use the phrase, “French Drain,” when they mean “Surface Drain” or “Channel Drain.”

French Drain Installation is what we specialize in.  Since 1993 we have installed over 2000 French Drains or Drainage Systems in Oklahoma.

Just what is a “French Drain?”  Many times people incorrectly.  A French Drain can protect your foundation!

use the phrase, “French Drain,”  to apply to many different types of Drains that could be used in a Drainage System.  The term is widely used and many times incorrectly connected to “Surface Drains,” or “Channel Drains.”

A Surface Drain has a grate that sits on top of a basin.  The basin is underground.  A Drain Pipe is connected underground to an outlet on the Drain Basin. Storm-Water Drains through the grate into the Drain Basin.  Once in the Drain Basin, water travels out of the basin through a Drain Pipe.  The Storm-Water continues downhill in an underground Drain Pipe to an exit point.

THIS IS NOT A FRENCH DRAIN!

A Surface Drain may come in many different shapes or sizes.  The Drain Grate may be round or square.  Here is a picture of a common Surface Drain.Surface Drain and Drain Pipe

A Channel Drain is a type of Surface Drain and many times is installed in concrete across sidewalks or driveways.Channel Drain

A French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged.

The dirt that was taken out to make the trench is hauled away.  It is replaced by some type of small stone or gravel depending on what is desired or available.  I prefer crushed 1 inch lime stone.  It is the most economical option in my area.  Pea Gravel or some other type of small stone can work just as well.    The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level).   In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed.  This helps maintain the integrity of the trench over time.  It also increases the cost of the French Drain and the amount of time to install it.  I install a trench liner in a French Drain about 20% of the time.  Most of the time a liner in not needed. A French Drain is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations.  It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it. The main downfall of a French Drain is that they, for the most part aren’t very pretty.  They don’t look very nice in a yard once they are completed.Depending on the area the French Drain is installed and the type of grass around the French Drain, will dictate whether grass grows over the lime stone.  Grass can grow up and through the gravel in the French Drain over time eventually covering the gravel.  This is Ok.  It won’t have a measurable effect on the performance of the drain. DONT COVER THE GRAVEL IN THE FRENCH DRAIN WITH DIRT.  THE FRENCH DRAIN WON’T WORK IF THE TRENCH IS CLOGGED WITH DIRT.  DON’T EVEN INSTALL IT IF YOU ARE GOING TO COVER IT UP WITH DIRT.

Many different types of Drains can be hooked together by one Drain Pipe.  The Drain Pipe then running to an Exit Point makes up a Drainage System.  One common type of Drain used in a Drainage System is A “French Drain.”  Many times a French Drain is installed close to a building foundation or in a low area next to a home or business.  This puts the French Drain in close proximity to Gutter Down Spouts.  Rather than have water come off the roof and out the Down Spout and on to the ground below, many times it is much better to tie a Gutter Down Spout Directly into a French Drain or near by Drain Pipe depending on the Drainage System Design.   Connecting The Down Spouts Directly into a French Drain is much  more efficient and causes suction to occur in the French Drain.  Connection of Gutter Down Spouts to a French Drain makes the Drainage System work better.

 

 

French Drain Before gravel is installed Drainage Systems can:

1.  Keep water away from foundations — A French Drain is best because it can move Surface Water and Sub-Surface Water (water moving under ground) away from the foundation.  Many times less experienced companies install Surface Drains to keep water away from foundations.  This can be a big mistake.  A Surface Drain can’t move or drain Sub-Surface Water.   Also A Surface Drain often can’t move enough water fast enough and easily becomes overwhelmed during a heavy rain.  A Surface Drain also can’t cover or protect a broad enough area. Surface Drains should be designed in a Drainage System to be located in smaller Drainage Areas moving moderate amounts of water.  Surface Drains look better than French Drains.  If ,”appearance” is more important than Drainage Capacity, Go with the Surface Drain.  Just know what you are getting into and what your expectations should be. One side of a foundation alone,  can be over 100 feet.  A 4 inch or 6 inch French Drain is best when protecting a large area such as a foundation.

2.  Keep water away from small or enclosed areas.  This might be a low area just through a gate on the side of a house, or the low area between a flowerbed and the wall of a house, or standing water on or near a sidewalk or driveway.  These types of Drainage Problems are best served with Surface Drains.  A Surface Drain can move water away from a low area that is relatively small.  This can occur in yards, flowerbeds, sidewalks and driveways.  A Surface Drain is designed to move Surface Water away from a problem area to a predetermined exit point.  Surface Drains are available in many sizes.  How quickly they remove standing water is usually determined by the size of the Drain Pipe that is connected to the Drain.

FRENCH DRAIN  CONNECTED TO GUTTERS

Many different types of Drains can be hooked together by one Drain Pipe.  The Drain Pipe then running to an Exit Point makes up a Drainage System.  One common type of Drain used in a Drainage System is A “French Drain.”  Many times a French Drain is installed close to a building foundation or in a low area next to a home or business.  This puts the French Drain in close proximity to Gutter Down Spouts.  Rather than have water come off the roof and out the Down Spout and on to the ground below, many times it is much better to tie a Gutter Down Spout Directly into a French Drain or near by Drain Pipe depending on the Drainage System Design.   Connecting The Down Spouts Directly into a French Drain is much  more efficient and causes suction to occur in the French Drain.  Connection of Gutter Down Spouts to a French Drain makes the Drainage System work better.


A “French Drain” Moves “surface water” away from a low lying problem drainage area. What flows over the ground.  Sub surface water  which runs underground  is not considered  when a drainage system is being installed.  People only think about what they can see and don’t think much about what they can’t see.

Channel Drain set in Driveway is one type of Surface Drain

Sub Surface water is water that is underground and saturated in the soil.  Just like water above ground (Surface Water) moves.  Water under ground moves too and is a very big part of any drainage problem.

Water flows over the surface into the area that floods and is a problem.  A big mistake that is made be the casual eye, is that all the water in a swampy problem area got there by running over the surface.  Yes, it probably did, but it also got there by moving there underground as well.  This is called SUB SURFACE WATER MOVEMENT, and it is important to any kind of Drainage System that might be installed.

If your problem water is partially Sub-Surface water, and you install a Drainage System that uses Surface Drains only, then you just wasted a lot of money!

Water can only be drained away that is on the surface.  It goes into the top of the Drain on the Surface.  It’s Name is ” A Surface Drain.”  It Drains Surface Water ONLY!

A French Drain can drain Surface water and Sub Surface water both.  It water is in the problem area by means of Sub – Surface movement, then it will enter the French Drain Laterally, under ground,  and be drained away along with the surface water.

When Installing a Drainage System, What kind of Drain Pipe do you use and what size Drain Pipe Do you need?

For a Drainage System you have 3 Choices of Drain Pipe.  You can use ADS,  Or Sewer and Drain, or Thick Walled Pvc Pipe.

ADS is Black and Flexible.  It is used in a majority of Drainage Systems.  It works well and is the easiest to install.

Covering ADS Drain Pipe

ADS is available in 3 inch , 4 inch, and 6 inch for residential and small business Drainage Applications.

Sewer and Drain Pipe is white, green, or grey and is thin walled.  It is used for cheap plumbing applications such as sewer lines.  It is also used for inexpensive Drainage Systems.  A Drainage System using Sewer and Drain Pipe is slightly cheaper than ADS.   It is rigid and harder to install than ADS. It takes more time to install and more digging is required at the joints or connections.  It is very difficult attaching a rigid Drain Pipe to a Curb outlet because the Pipe does not flex at the connection.  The pipe hits the curb outlet at a downward angle and does line up straight with the connection.  Many Drain Installation Companies use a piece of ADS on the end of the Sewer and Drain pipe and then connect it to the curb outlet.  Many times there is no other way to connect them depending on your downward slope.

 

Sewer and Drain

Green or White Sewer and Drain Pipe

Sewer and Drain is brittle after a short amount of time.  You can break it with a hammer.   Tree roots, many times squeeze the pipe and crack it causing it to leak.   It is not a good long term solution for anything.

Old Sewer and Drain Pipe

Old Sewer and Drain Pipe

Thick walled PVC is superior to ADS and Sewer and Drain.  It will last a lifetime.  It won’t crack under normal circumstances.

That being said, It is The most difficult of all to install.  It is not for weekend warriors or your brother-in-law who says he knows what he is doing.  Someone with a lot of experience is needed to install a Thick Walled PVC Drainage System.

SD and 40 schedule

40 Schedule PVC Drain Pipe on the right, Sewer and Drain on the left.

Oh, by the way, 40 Schedule or 200 Class PVC is by far the most expensive.

If money is no object, then absolutely hire an Expert to install a Thick walled PVC System.

There are two types of Thick Walled Pvc Pipe available for Drainage Systems, 40 Schedule and 200 class.

Forty Schedule is always the same thickness at a particular size pipe.

Two Hundred Class gets thicker as the pipe gets bigger.

Forty Schedule is thicker in pipes smaller than 2 inch.

Two hundred Class is thicker in pipes over 2 inch.

Typically 4 inch pipe is most commonly used in a Drainage Systems.  Forty Schedule and 200 Class are both very good in the 4 inch Size.

 

The size of Drain Pipe you use in your Drainage System is fairly simple.  You can use 3 Inch, 4 Inch, or 6 Inch.  Sometimes 2 inch can be used on a small single drain but it is easily overwhelmed by too much water.

Four Inch, as stated earlier is the most common size used in a Drainage System.

If your system is a Drainage System and not a Flood Prevention System, then 4 Inch Should be fine for most applications.

If your drainage system must handle a lot of water in a hurry and is designed intercept water to protect property then two 4 inch pipes may be needed or one 6 inch Pipe.  It can vary.

In 2015 we installed a Flood Prevention System that had two 6 inch pipes in the same trench.  Our customer never had water in her garage again.

If you can afford larger Drain Pipe or more than one Drain Pipe in the same trench, your Drainage System should do its job well.

If you connect 5 large Surface Drains to one small 3 inch pipe, be prepared for poor performance.  I’ve seen a large French Drain connected to a 3 inch pipe.  The water shot out of the exit point like a cannon and the problem drainage area stayed flooded for a long time.

I try not to use 3 inch at all for a Drainage System and I am very careful not to attach too large or too many drains to 4 inch.

Surface Drains look nice but they have limited applications.  They must be installed in situations that they are designed for.  Surface Water only in smaller volume applications.  Surface Drains don’t move as much water as French Drains.

Oklahoma Drainage and Sprinkler Repair Installs Surface Drains and French Drains.  Some times it is up hill in all directions from the Problem Drainage Area.  This problem can be solved by installing a Sump Pump.  When the cavity fills, the water is pumped away to the point where the water exits the drain which can be a curb outlet or a pop-up emitter.

Some Drainage Systems are complex and incorporate several types of drains.  Most Drainage Systems , however are basic and require just one type of DrainOklahoma Drainage and Sprinkler Repair installs a variety of drains to solve a variety of problems. French Drains, Surface Drains, and Channel Drains are most commonly used.  If you live in Edmond and need a Channel Drain installed across your driveway, or if you live in Norman and need a French Drain in your backyard, or if you live in Oklahoma City and need a Surface drain installed next to your sidewalk, we can help. Channel Drain Installed by CMG In Yukon Oklahoma Drainage and Sprinkler Repair provides Drainage Diagnostics .  A Drainage Diagnostic is a scheduled appointment where we come out and look at your Drainage Problem and get your input on the situation.  We look at all the variables that are causing your Water-Runoff Problems and design a Drainage System to solve it.  French Drains and Surface Drains are used to make up the Drainage System.

Typically many things must be considered when completing a Drainage Diagnostic.

1.  Identify the areas being damaged by water and determine if there are any hidden areas.

2.  Identify the sources of water causing the damage.  Most Drainage Problems have more than one source.  A water source can fall from the sky as rain, or can flow down the hill as storm-water runoff, or can flow from a gutter down-spout (yours or your neighbor’s),  or flow under ground as sub-surface water flow, or water can flow off a sidewalk, driveway, or street.  (These are the most common)

3.  Identify the Exit Point by determining where we want to take the unwanted water.

4.  Determine what type of Drains can best solve the Drainage Problem.  We utilize: French Drains, Surface Drains, Channel Drains, Trench Drains, and Sump Pumps.

5.  Determine what type and size of Drain Pipe is needed to accommodate the volume of water to be drained.  Larger is always better!  Big Drains with Small Drain Pipes never works!

Standing water can cause a lot of damage to your yard.  The above picture was from a French Drain Installation in Oklahoma City.

Many times we wait until things dry out a bit before beginning a French Drain Installation.  Some times the water never goes away.  So we start digging in standing water and putting the mud in a wheelbarrow.   We then haul it to a dump trailer to be hauled away.  It isn’t the easiest thing to do.

 

Liner and French dran

Perforated Pipe, Filter , and Liner installed in a drainage trench.

The water started draining away as soon as we dug the Drainage Trench.  Once the Pipe and Limestone were installed, it drained away even faster.

The trench liner allows sub surface water to pass through it and reach the French Drain Pipe.  The reason it is installed is to maintain the integrity of the drainage trench so it doesn’t collapse over time.  It also helps protect the pipe from filling up with mud or sand, clogging the French Drain.

Below is a picture of a French Drain that we had to take out and replace because it had no liner or filter around the Pipe.

The type of rock that covers a perforated French Drain Pipe can be just about any type of quality gravel or crushed stone.  Very small crushed stone or sand is not a good idea, however.  The water must be able to flow through the stone to reach the perforated pipe.

French Drains can be installed by themselves, or as part of a Drainage System that uses other French Drains, Surface Drains, or other Drain combinations.  Typically a French Drain is used to protect a broad area that has a lot of standing water.  A French Drain might run along side a homes foundation, or beside a driveway, or on any Drainage Project where Sub-Surface water is the primary problem.  If water is running toward your home under ground ( through sandy soil), A French Drain is the only Solution  for draining away water flowing under ground.

Drainage Trench

Just what is a “French Drain?” Many times people incorrectly

French Drain can protect your foundation!

use the phrase, “French Drain,” when they mean “Surface Drain” or “Channel Drain.”

 
 

A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench. The French Drain Trench runs through a Problem Drainage Area that needs to be drained.   The French Drain Pipe is perforated (Full of Small Holes) and has Neo-Prene Soc around the pipe.  This soc helps prevent debris from clogging the French Drain Pipe.

 

The dirt that was taken out to make the trench is hauled away. It is replaced by some type of small stone or gravel depending on what is desired or available. I prefer crushed 1 inch lime stone. It is the most economical option in my area. Pea Gravel or some other type of small stone can work just as well. The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level). In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed. This helps maintain the integrity of the trench over time. It also increases the cost of the French Drain and the amount of time to install it. I install a trench liner in a French Drain about 20% of the time. Most of the time a liner in not needed.

A French Drain is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations. It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it.

The main downfall of a French Drain is that they, for the most part aren’t very pretty. They don’t look very nice in a yard once they are completed.

French Drains can be installed by themselves, or as part of a Drainage System that uses other French Drains, Surface Drains, or other Drain combinations.  Typically a French Drain is used to protect a broad area that has a lot of standing water.  A French Drain might run along side a homes foundation, or beside a driveway, or on any Drainage Project where Sub-Surface water is the primary problem.  If water is running toward your home under ground ( through sandy soil), A French Drain is the only Solution  for draining away water flowing under ground.

Harsh weather in Oklahoma seems to becoming more common.  In 2013,  Norman Oklahoma had 4 inches of rain in two hours.  That’s the most rain in a short time that I can remember.  Storm-Water runoff can cause damage to all types of property and buildings.  Water getting inside your house is never a good thing.  A Drainage System that utilizes a French Drain can help.

Drains can protect your home and property from water damage.  Oklahoma Drainage install a wide variety of Drains in many different places.  A Drain or Group of Drains with Drain Pipe going to an exit point is a “Drainage System.”

A “French Drain” Moves “surface water” away from a low lying problem drainage area.  Sub surface water is many times not considered or thought about when a drainage system is being installed.  People only think about what they can see and don’t think much about what they can’t see.

Sub Surface water is water that is underground and saturated in the soil.  Just like water above ground (Surface Water) moves.  Water under ground moves too and is a very big part of any drainage problem.

Water flows over the surface into the area that floods and is a problem.  A big mistake that is made be the casual eye, is that all the water in a swampy problem area got there by running over the surface.  Yes, it probably did, but it also got there by moving there underground as well.  This is called SUB SURFACE WATER MOVEMENT, and it is important to any kind of Drainage System that might be installed.

If your problem water is partially Sub-Surface water, and you install a Drainage System that uses Surface Drains only, then you just wasted a lot of money!

Drainage Systems can be made up of one drain or a combination of many drains.  Drainage  problems can be very complex.   Complex Drainage Problems may require a combination of several different types of drains all inter-connected and working together.  Other times the drainage problem may be simple and straight-forward requiring only one drain or several of the same type of drain connected together.

An example of a complex drainage system would be:  A French Drain in the back yard connected to a Surface Drain near a flower bed connected to several gutter downspouts, which are connected to a Channel Drain going across a driveway, which is connected to additional Surface Drain in the front yard, which runs to a Curb Fitting that lets all the water drain out on to the street.

A simple Drainage System might consist of a Surface Drain that is connected to a second Surface Drain which runs to a Pop-up Emitter which lets water drain over the curb and into the street.

An “Exit Point” is the term used for where all the water leaves the Drainage System.  Determining the Exit Point is very critical.  It is one of the first things we do when diagnosing a Drainage Problem.

Drainage Systems can:

1.  Keep water away from foundations — A French Drain is best because it can move Surface Water and Sub-Surface Water (water moving under ground) away from the foundation.  Many times less experienced companies install Surface Drains to keep water away from foundations.  This can be a big mistake.  A Surface Drain can’t move or drain Sub-Surface Water.   Also A Surface Drain often can’t move enough water fast enough and easily becomes overwhelmed during a heavy rain.  A Surface Drain also can’t cover or protect a broad enough area. Surface Drains should be designed in a Drainage System to be located in smaller Drainage Areas moving moderate amounts of water.  Surface Drains look better than French Drains.  If ,”appearance” is more important than Drainage Capacity, Go with the Surface Drain.  Just know what you are getting into and what your expectations should be. One side of a foundation alone,  can be over 100 feet.  A 4 inch or 6 inch French Drain is best when protecting a large area such as a foundation.Surface Drain Installed next to sidewalk in Oklahoma City.

2.  Keep water away from small or enclosed areas.  This might be a low area just through a gate on the side of a house, or the low area between a flowerbed and the wall of a house, or standing water on or near a sidewalk or driveway.  These types of Drainage Problems are best served with Surface Drains.  A Surface Drain can move water away from a low area that is relatively small.  This can occur in yards, flowerbeds, sidewalks and driveways.  A Surface Drain is designed to move Surface Water away from a problem area to a predetermined exit point.  Surface Drains are available in many sizes.  How quickly they remove standing water is usually determined by the size of the Drain Pipe that is connected to the Drain.Surface Drain Installation in Norman

Simply put, a Drainage System is one or a group of underground Drain Pipes that take water away from a place that has water standing on it or flowing across it.  The water that is in the problem area, can be causing damage or may be inconvenient or both.  (Usually Both)  A simple Drainage System is a Drain for the water to enter, a Drain Pipe to move the water away from the Drain, and an Exit Point for the water to be released out of the Drain Pipe.

Drainage Systems quickly can become more complicated.  Considerations must include:

How does the water get to the problem area?  There may be one or many sources.

Water Sources:

1.  It falls from the sky directly

2.  It flows down hill over the surface (surface water)

3.  It flows underground under the surface (sub-surface water)

4.  It flows from the edge of a roof ( There may be many roofs near the problem area, neighbors etc.)

5.  It flows from a gutter downspout

6.  It flows over the edge of a gutter because the gutter is too small is is clogged

7.  It flows up from the ground (seeps and springs are common in Oklahoma)

8.  It flows from a sprinkler system use ( yours or your neighbors)

9.  It flows from a leaking pipe ( water mains, water meters, water lines, sprinkler pipes, sprinkler valves)

There are other reasons for Drainage Problems, the above reasons are just the most common.

Once the number of water sources is determined, a rough estimate of the amount of water that needs to be drained away on average must be estimated.  This can be simplified down to “SMALL, MEDIUM, OR LARGE AMOUNTS OF WATER TO BE DRAINED AWAY.  You don’t have to be an engineer trying to calculate fluid dynamics.  Experience at diagnosing drainage problems helps however.  How much water needs to be moved will help determine the type and size of the Surface Drain or French Drain that needs to be installed.  It also helps to determine the size of Drain Pipe required for the Drainage System.  A good rule to follow is, “If in doubt, install a larger Drain and Drain Pipe.”  Unused Drainage Capacity is better than property damage caused by a Drain that is overwhelmed by too much water.

For home and small business use typical materials used are:

6 inch, 9 inch, and 12 inch Surface Drains

3 inch, 4 inch, and 6 inch Drain Pipes

3 inch, 4 inch, and 6 inch French Drains

French Drains move more water than Surface Drains —

French Drains move Surface Water and Sub-Surface Water

Surface Drains move Surface Water only

Surface Drains look nicer than French Drains in most cases

Once the type and number of drains is determined and what size Drain Pipe will connect them, an exit point must be selected.  (Where is the Drainage System going to take the water to and release it?)

The Drainage Curb Fitting is installed when the desired exit point for the French Drain will release the Drainage Water into the Street.   The Drainage Curb Fitting is rectangular in shape and made to be installed through the curb.  A small section of Curb is cut out with a concrete saw.  The Section is a few inches wider than the Drainage Curb Fitting.  We then install new concrete around the curb fitting.  Once the concrete has dried, the Drain Pipe coming from a French Drain or Surface Drain is connected to the Drainage Curb fitting and then covered with dirt.Cutting The Curb and Installing Curb Fitting for French Drain

The Drainage Pop-Up Emitter is connected to the end of a Drain Pipe.  It is downhill from a French Drain or a Surface Drain.  It is a small release basin with a green pop-up lid.  When releasing water, it pops up about an inch to release the water from the French Drain or Surface Drain.  When the Storm Water has moved through the Drainage System and out of the Pop-Up Emitter, the green lid closes back to its original closed position.  The emitter is designed to release water out into a yard or down a hill or other desirable Drainage Exit Point where there is no curb.Popup Emitter to release water from a Drainage System in Yukon.

A good place for a French Drain

We just finished a 4 inch Drainage System in Yukon.  It was a complicated system to install.  It utilized 4 inch French Drain in the flower beds,  12 inch Surface Drains on the side of the house,  6 inch French Drain along the garage foundation with 2 Pop – Up Emitters in the back yard and 3 Curb Fittings in the front.    First we installed 4 inch French Drain in the flowerbeds on both sides of the front door.  We connected 4 inch solid Drain Pipe into the French Drain and ran them underside walk to the curb.  Next we cut the curb with a concrete saw and installed 3 curb outlets for 3 separate French Drains.

Next we installed 4 12 Inch Drain Basins with grates along both sides of the house continuing with Solid Drain Pipe to the Pop-Up Emitters on the back fence. Finally we completed the Drainage System by installing a long run of 6 inch French Drain down the side of the garage foundation.   Installing the French Drains in the flower beds was the most difficult and took the most time.  Each French Drain took over a ton of crushed limestone to fill the French Drain trench.  The Six inch French Drain took even more limestone.

French Drains as part of a Drainage System –

Many times people use the term ” French Drain” as general name for a Drain used in or around your home.  French Drains are designed to move a lot of water over a large flooded area.  They are also designed to take water in on the surface of the ground or below the surface of the ground.  This is very important if the water coming into the flooded area is moving through the ground or coming up from underneath.  ” Sub Surface Water Movement.”  The picture below is not a French Drain!

A French Drain Can Handle Standing Water

A French Drain can take in water in a broad area.  It can move a much larger volume of water compared to a Surface Drain.  Also, it can move sub surface water moving into the area where a Surface Drain won’t move any water at all.

Surface Drains are designed to move surface water only on a smaller scale in confined areas.

Each solves specific drainage problems.  A Drainage System may use one or both together or even several using many types of drains.

Do you have standing water in a large area in your yard?  Typically this calls for a French Drain.  A French Drain is a great way to control standing water in a large grassy area.  It can also protect areas from flooding to a certain degree.  As long as the French Drains capacity to move water is not exceeded.  If the French Drains capacity is exceeded then water will stand in the drainage area until the rain stops and the drain has time to catch up.  A good way to prevent this is to install a bigger French Drain with a larger pipe.  The difference between a 3 inch French Drain and a 6 inch French Drain is huge.

Another way to beef up a French Drain is to connect gutter down spouts in front of the French Drain.  The water coming off the roof causes suction in the French Drain Behind it.  This greatly increases the French Drains ability to move water without increasing the size of the French Drain Pipe.

Recently we installed a French Drain inside the court yard of a rest home in Norman.  We had several interesting challenges to overcome that were not typical for a French Drain Installation.  The court yard was in the center of the home and was a secure area for the patrons.  We had to put down painters tarps to run our wheel barrows over.  We took out 44 loads of dirt and brought in 52 loads of Crushed one inch lime stone for the French Drain.  Each trip was over a hundred yards from the trailer in the parking lot, in the front door, down the hall, making two turns along the way.  Each time we had to be escorted by security.  Needless to say, the installation of this particular drainage system took a while.In the above picture, the French Drain runs along the low area crossing all the areas where water would stand each time it rained.

When a French Drain is installed, a big mistake that is made by many people is to cover up the gravel with dirt.  This is a big mistake.  Basically it is ” Putting the cork back in the bottle.”  If the French Drain is in full sun and has a type of grass surrounding it that spreads on its own such a ” Tift” or “Bermuda” , Grass will grow over it and the French Drain will eventually disappear.  Grass covering a French Drain is a good thing if it grows across the drain without adding dirt.  The Grass thatch acts a water filter preventing clogging and extending the life of the Drainage System.

When a French Drain is in Full Shade, or the surrounding grass will not spread on its own, such as with Fescue,  other steps must be taken.  One option is to just leave it alone.  If you don’t mind how it looks, it will drain a large amount of water for many years.  Many times a French Drain can be a landscaping focal point.  They can be dressed up with all kinds of Rocks and Stones and Plants.

Just what is a “French Drain?”  Many times people incorrectlyA French Drain can protect your foundation!

use the phrase, “French Drain,”  to apply to many different types of Drains that could be used in a Drainage System.  The term is widely used and many times incorrectly connected to “Surface Drains,” or “Channel Drains.”

A Surface Drain has a grate that sits on top of a basin.  The basin is underground.  A Drain Pipe is connected underground to an outlet on the Drain Basin Storm-Water Drains through the grate into the Drain Basin.  Once in the Drain Basin, water travels out of the basin through a Drain Pipe.  The Storm-Water continues downhill in an underground Drain Pipe to an exit point.

THIS IS NOT A FRENCH DRAIN!

A Surface Drain may come in many different shapes or sizes.  The Drain Grate may be round or square.  Here is a picture of a common Surface Drain.Surface Drain and Drain Pipe

A Channel Drain is a type of Surface Drain and many times is installed in concrete across sidewalks or driveways.Channel Drain

A French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged.

The dirt that was taken out to make the trench is hauled away.  It is replaced by some type of small stone or gravel depending on what is desired or available.  I prefer crushed 1 inch lime stone.  It is the most economical option in my area.  Pea Gravel or some other type of small stone can work just as well.    The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level).   In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed.  This helps maintain the integrity of the trench over time.  It also increases the cost of the French Drain and the amount of time to install it.  I install a trench liner in a French Drain about 20% of the time.  Most of the time a liner in not needed.French Drain A French Drain is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations.  It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it. The main downfall of a French Drain is that they, for the most part aren’t very pretty.  They don’t look very nice in a yard once they are completed.Depending on the area the French Drain is installed and the type of grass around the French Drain, will dictate whether grass grows over the lime stone.  Grass can grow up and through the gravel in the French Drain over time eventually covering the gravel.  This is Ok.  It won’t have a measurable effect on the performance of the drain.DONT COVER THE GRAVEL IN THE FRENCH DRAIN WITH DIRT.  THE FRENCH DRAIN WON’T WORK IF THE TRENCH IS CLOGGED WITH DIRT.  DON’T EVEN INSTALL IT IF YOU ARE GOING TO COVER IT UP WITH DIRT.

Standing water can cause a lot of damage to your yard.  The above picture was from a French Drain Installation in Oklahoma City.

Many times we wait until things dry out a bit before beginning a French Drain Installation.  Some times the water never goes away.  So we start digging in standing water and putting the mud in a wheelbarrow.   We then haul it to a dump trailer to be hauled away.  It isn’t the easiest thing to do.

The water started draining away as soon as we dug the Drainage Trench.  Once the Pipe and Limestone were installed, it drained away even faster.

The trench liner allows sub surface water to pass through it and reach the French Drain Pipe.  The reason it is installed is to maintain the integrity of the drainage trench so it doesn’t collapse over time.  It also helps protect the pipe from filling up with mud or sand, clogging the French Drain.

Below is a picture of a French Drain that we had to take out and replace because it had no liner or filter around the Pipe.

This year Oklahoma Drainage and Sprinkler Repair has addressed many standing water problems and drainage issues for residents and business owners of Oklahoma.  On one occasion, we installed a Surface Drain in the middle of a driveway.  After a rain, water was standing in front of the garage and would flow under the door when it got too deep.  We cut the driveway, Installed the Surface Drain, and replaced the cement.  Problem Solved.

Another Drainage Problem involved installing a Sump Pump in a basement floor.  The basement would flood after a hard rain.  Again, Problem solved!

Harsh weather in Oklahoma seems to becoming more common.  In 2013,  Norman Oklahoma had 4 inches of rain in two hours.  That’s the most rain in a short time that I can remember.  Storm-Water runoff can cause damage to all types of property and buildings.  Water getting inside your house is never a good thing.  A Drainage System that utilizes a French Drain can help.

Drains can protect your home and property from water damage.  Oklahoma Drainage and Sprinkler Repair installs a wide variety of Drains in many different places.  A Drain or Group of Drains with Drain Pipe going to an exit point is a “Drainage System.”

A Channel Drain is a type of Surface Drain and many times is installed in concrete across sidewalks or driveways.  It is long and narrow with a grate on top.Channel Drain installed in a sidewalk by a front door.

A French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  A  Trench Liner is sometimes used depending on the Drainage System Design and the type of soil.   The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged. A trench is dug that is slightly wider than the French Drain Pipe that is being used.  There are several sizes of French Drain Pipe.   Three Inch, Four Inch, and Six Inch are the most common sizes of French drain Pipe.
