French Drain Installation in Norman

Recently  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.”

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.

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.

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

Recently we installed a large French Drain System for a home in North Edmond.  Their gutters were dumping a huge amount of water into the flower beds.  Once in the flower beds, the water traveled down into the foundation and filled up the air conditioner vents.  We installed a large French Drain with 6 inch perforated pipe.  The gutter down spouts were removed and the gutters were run straight into the French Drain Pipe.

Oklahoma Drainage installs a wide variety of drains to solve a wide variety of Drainage Problems. If you need a Channel Drain installed across a sidewalk, We can help. If water is seeping into your foundation, A French Drain could solve the problem. If water is standing in a low spot in your backyard, a Surface Drain will be a good addition.

Drainage Problems are common with many homes in Oklahoma.  Storm-water run-off can cause damage to foundations, driveways, and sidewalks.  It can also ruin expensive plants and trees and yards.

Oklahoma Drainage and Sprinkler Repair has been diagnosing and solving Drainage Problems since 1993.  Water has the ability to get into places around your home where you really don’t want it to be.  Some drainage problems are easy to solve.  Typically water enters the problem drainage area one way from one source.  The really tricky drainage problems occur when water enters the problem drainage area from multiple directions and from multiple sources.  Sometimes a secondary water source can’t be seen or identified until the primary water problem source is eliminated.

An example of this occurs when water is running into a problem area in an obvious way over the ground where you can see it.

Simple enough.

A drainage system is installed with a surface drain as the “intake” with drainage pipe running to an exit point.  Initially the water drains away and everything looks great.  The next day water is back and is all around the surface drain, but below the edge and it hasn’t rained at all, so no additional water ran over the surface of the ground to flood the area.  The primary water source was solved, ( The surface water run off ) but the secondary water source was not.  Which was sub-surface water, (ground water) running into the area.  A surface drain can’t drain “ground water.”  A French Drain should have initially been installed instead of a Surface Drain.  A French Drain can drain both Surface Water and Ground Water.

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. The dirt that is 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 Pipeor 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.

Keep water off your driveway with a channel drain

Standing water comes from many sources.  It causes damage to  sidewalks, driveways, and foundations not to mention plants, trees, and  grass.  Does the side of your house flood because your neighbor doesn’t  have gutters, or does your sidewalk turn into a moat after a heavy rain,  or worst of all, is water seeping into your foundation and duct work  after a thunderstorm?  Theses are just a few of the Drainage  Problems that Oklahoma Drainage and Sprinkler Repair can help with.  We can design a Drainage  System to fit your specific needs.  We install many types  of Drains  to solve many types of problems.    French  Drains, Surface  Drains, Channel  Drains, Basement  Drains, Trench Drains, Basin Drains, and Sump  Pumps are utilized.

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

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.

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.  PUTTING DIRT OVER A FRENCH DRAIN IS LIKE PUTTING A CORK BACK IN A BOTTLE.

French Drain Running Through Low Areas

French Drains are designed to cover large areas and move lots of water.  During a hard rain water will seep down through the gravel and into the Perforated French Drain Pipe that is buried under the gravel.  The water fills into the pipe and moves down hill to the desired Exit Point.  French Drains like the one in the picture above that are in the sun most of the day will have grass that overgrows the limestone.  The gravel will disappear over time.  The French Drain will continue to work even after the grass has grown over it.  A “Thatch Filter ” is made up of the grass that covers the French Drain.  The French Drain then has two filters.  First is the Neo-Prene Soc that comes around the Perforated French Drain Pipe.  Later when the grass grows over it, the French Drain then has a second Thatch Filter.  This ensures that the French Drain Pipe won’t clog over time with dirt, sand, or debris.  This only works with grass that does well in the sun like Bermuda or Tift.

Shade Grasses won’t grow up and through French Drain gravel.

YOU DON’T WANT TO COVER THE FRENCH DRAIN  WITH DIRT.  IT WILL GREATLY REDUCE THE DRAINAGE PERFORMANCE OF THE FRENCH DRAIN.  IT DEFEATS THE ENTIRE REASON FOR THE FRENCH DRAIN.  IF YOU DON’T LIKE THE WAY IT LOOKS AND CAN’T BE PATIENT ENOUGH TO WAIT UNTIL  THE GRASS GROWS THROUGH IT IF IT IS IN THE SUN, THEN DON’T INSTALL IT AT ALL.

IF THE FRENCH DRAIN IS INSTALLED IN THE SHADE YOU CAN USE DECORATIVE ROCK TO MAKE A FOOT PATH OR ROCK GARDEN ON TOP OF IT.  YOU ARE ONLY LIMITED BY YOU IMAGINATION.

French Drain Installation—   French Drains are designed to do a lot of things.  If you have an area that has unwanted water standing in it or running across it, a French Drain can be the answer.  A French Drain is a trench that runs across the Drainage Problem Area.  A French Drain Pipe is placed in the bottom of the trench.  The French Drain Pipe is perforated with thousands of small holes.  In most cases the Drain Pipe has a nylon soc around the pipe to act as a filter for the French Drain.  The French Drain trench is then filled with some type of small rock or stone.  We typically use crushed 1 inch Lime Stone to cover the French Drain Pipe.  The dirt that was dug out of the trench is taken away or spread out around the French Drain.  The Lime Stone replaces the dirt and fills the French Drain Trench all the way to the surface.

Covering a French Drain with dirt is a bad idea.  Water can’t get into the drain through the stones if it is clogged with dirt.  If you are more concerned about how it looks over what it does, then don’t install it in the first place.  French drains can move a lot of water and protect property such as foundations, sidewalks, plants, yards just to mention a few things.  If you don’t like how a French Drain looks then change it.  Put Stepping stones on top of it, use river rock to improve the look, You are limited only by your own creativity.

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.

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.
