Today we are installing a French Drain system for a customer in East Norman.  She has water running into her front door through her flower bed.  The bed acts like a pond and over-spills onto her front porch and then through her front door.  To solve the problem, we are installing a French Drain running across her flower bed and under her sidewalk.  Once under the sidewalk the French Drain will connect to Solid Drain Pipe and continue on down the hill to the exit point where we will install a pop-up emitter.  There are two gutter downspouts that will be connected into the French Drain System along the way.

A French Drain that will keep standing water away!

A French Drain that will keep standing water away!

 

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. 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 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.

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.

French Drain March 2011

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.

French Drain with Colored Gravel

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.

Edmond Oklahoma has been the location for many French Drain Installations for CMG in the past several years.  Recently we ripped out an old Surface Drain that was under a deck.  The Surface Drain was too small for the job and did not Protect the Foundation from Standing Water


 The First step was to take out part of the deck along the wall.  Next we took out the Surface Drain and the Three Inch Pipe which was too small.  Digging a trench along the foundation came next.  We had to ensure the, “Fall” to make sure the water would run from left to right. 


 Next a French Drain Liner  needed to be installed.  This was necessary to maintain the integrity of the trench and to keep the French Drain Pipe from filling up with sand and getting clogged over the next few years.  CMG then installed 4 inch ADS Perf/Soc French Drain Pipe along the course of the French Drain.  Next we connected the end of the French Drain Pipe to Solid 4 Inch ADS Drain pipe to continue along the trench to the Pop-Up Emitter at the Exit Point.

Connecting a gutter to a Drainage System

CMG installed a 4 inch French Drain in East Norman this week.  The customer had water standing on the side of his house that was causing foundation damage.  He contracted a Structural Engineer to come out and look at the Drainage Problem and to give him some advise.

6 inch French Drain

The Structural Engineer recommended a French Drain to protect and draw water away from the foundation.  He said that, “he had recommended French Drain Installation to solve similar problems for home owners many times in the past.  The Structural Engineer was confident that it would solve the Drainage Problem.

Next, our customer went online and found us by searching under, ” Norman Oklahoma French Drain.”  He also checked us out on Angie’s List and Found that we were one of the highest ranked Drainage Contractors in the state of Oklahoma for installing French Drains.

Drain Pipe running to Pop-Up Emitter

The Gentleman gave us a call to set up an appointment.  CMG arrived on the agreed time and provided a ( Free- No Obligation- Drainage Diagnostic and Quote) We came out and looked at his Drainage Problem and designed a Drainage System to solve his, Standing-Water Problem.”  We also recommended a surface drain in a corner where water was coming off a steep part of the roof and overwhelming the gutter.

Installing a curb outlet for a French Drain in Norman

The customer let us know that he was ready to move forward.  We scheduled the Drainage System Installation for the following week.  When the scheduled day arrived, we installed the Drainage System.  The Drain was made up of a 6 inch French Drain running 30 feet along the East side of the house.  It curved around the corner of the house.  At that point a 12 inch Surface Drain was connected to the French Drain with 4 inch pipe.  The 6 inch French Drain at that point changed to 6 inch Solid Drain Pipe and continued under ground 65 feet to a pop-up emitter at the curb in the front yard near the street.

Problem solved!

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.

French Drains can utilize  several types and sizes of French Drain Pipe.  An older type that is not commonly used any more is 4 inch PVC Pipe with large half inch holes drilled in the Pipe.  This doesn’t work very well,   Because the holes are too large and the number of holes in the French Drain Pipe are too few.  Also there is no filter or “Soc” around this particular French Drain Pipe.  If it is used in sandy or loose soil the holes will clog and the pipe will fill up with sand.  PVC French Drain Pipe should be avoided.

ADS French Drain Pipe is much better, the holes are smaller and much more numerous.  It also comes inside a soc that acts as a filter and helps keep sand and debris out of the French Drain Pipe.  It works very well.

For Small business and Residential French Drains, Four inch ADS Perf/Soc French Drain pipe is adequate and the most common.  It is used for the majority of all French Drains installed.  French Drains can be installed using 3 inch ADS Perf/Soc but many times it is too small and can be overwhelmed by a heavy rain or from a bad design.  (Too many gutter down spouts connected directly into the French Drain, For Example)  Three Inch French Drain Pipe should be avoided if possible.

Six inch  ADS Perf/Soc French Drain Pipe is usually a good idea when possible.  It carries a much larger volume of water.  Six Inch French Drains are rarely overwhelmed.

Installing Gravel on top of a 6 inch French Drain

The Drawbacks to 6 inch French Drain installation are:  1.  The Materials Cost is higher for six-inch French Drain Compared to Four Inch Pipe.
                                                                                                                    2.  Many times 6 Inch French Drain Pipe is too large for many applications, Such as going under a fence or sidewalk.  
                                                                                                                   3.  The trench for a 6 inch French Drain must be much larger than a 4 Inch
                                                                                                                   4.  The amount of gravel or limestone or River Rock used to Cover the 6 inch French Drain is Much larger
 
All things being considered, the performance and longevity of a 6 inch French Drain is well worth it if you are trying to protect something of value to you!  If the higher cost and the additional labor and materials are not a problem and 6 inch French Drain pipe is not too big for what you want to do then a 6 inch French Drain would be the best.  
French Drain Installation can prevent water from getting into your air conditioner floor ducts.

A common Drainage Problem for people in Central Oklahoma is ground water seeping into floor air conditioner  ducts.  This can cause very costly damage to a home or business.  Water-proofing Ducts, or even worse, trying to remove mold from duct work can cost big bucks.   Structural Engineers typically recommend  French Drain Installation  to keep water out of ducts.   French Drains catch and remove sub-surface water that is traveling underground toward a foundation. It is intercepted by the French Drain before it can seep under the building in question.   Because this water is not usually seen, it may not be taken into consideration when diagnosing drainage problems.  Surface Water traveling to a problem area is obvious as it flows on the surface in plain sight.

French Drains can also be used to remove water that is standing in a large area such as up against a foundation or along a fence.  French Drains don’t do so well in tight small areas.  These areas are best suited for a Surface Drain with a grate.  Many times we install French Drains along foundations after a home owner has spent large amounts of money on foundation repair.

Recently we installed a French Drain in Norman.  Our customer had water running down the hill from his neighbor’s Sprinkler System into the North wall of his house.  Over time the ground became saturated and water seeped under the wall and into his floor air conditioning vents.  We installed a 4 inch French Drain along the North wall of his house to provide a barrier to the continuous water flow.  In a few days the moss that was growing on the side of his house began to die from lack of water.  A Duct company came in and cleaned out is vents.  The French Drain removed the surface and sub surface water that was flowing into his home.   Problem solved.

Installing Surface Drain in Driveway

Installing Surface Drain in Driveway

CMG Sprinklers and Drains Recently installed a Drainage System in Nichols Hills.  The Drainage System was made up of a 4 inch French Drain starting in the back yard.  It ran between the garage and the pool.  Several gutters were connected directly into the French Drain.  From this point, we expanded up to a larger 6 inch Drain pipe to handle the added water into the system from the gutters.  In several places the French Drain had to run through areas where Sprinkler Pipes were in the way.  We had to re-rout all the Sprinkler Pipes and Wires under the French Drain.

Once the Sprinkler System had been redesigned and the gutters had been connected, CMG ran the 6 inch Drain Pipe from the end of the French Drain, around the house to release through the curb.  We cut the curb and installed a 6 inch curb fitting with acrylic concrete.  A few days later a major thunderstorm poured down on the property.  The French Drain and the Drainage System Worked Perfectly.

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.

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. 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 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.

 

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 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.  CMG typically uses 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.

When water come in contact with the French Drain, it seeps down through the stones and into the French Drain Pipe.  It then flows through the Drain Pipe to the exit point.  Typically a French Drain will have two possible exit points.   The First is called a “Pop-Up Emitter.”  It is a Green Lid on top of a release basin for the French Drain.

The second type of Exit Point for a French Drain is a “Curb Fitting.”  The Curb Fitting is installed through the curb going out into the street.  The French Drain Pipe runs to the Curb.  The curb is cut out and the Curb Fitting is cemented through the Curb.

French Drains are designed to move large amounts of water.  A French Drain moves water away from the Drainage Problem area from the Surface like a large Surface Drain, But also below ground, or sub surface.  Most people don’t take into account the water that flows to a problem area underground.  Sub surface water flow is not eliminated by a Surface Drain.  A French Drain can move away water that is below the surface of the ground and drain away water that is on the surface.

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.

A French Drain is a long perforated pipe in the bottom of a trench.  The trench runs through the problem drainage area.  The trench is filled with gravel or crushed lime stone.  The French Drain takes in water any place that water runs into the trench.

A French Drain will move large amounts of water from the Drainage Problem Area to the Exit point.

A French Drain will Drain away water that gets to the Drainage Problem Area in 3 ways.

1.  Water gets to the problem area by falling from the sky.

2.  Water gets to the problem area by flowing down hill over the ground.

3.  Water gets to the problem area by flowing underground. (Sub-Surface water flow)

Number 3,  Sub-Surface water flow is the big consideration.  When doing a Drainage Diagnostic, this is the area that is many times missed or not considered by less experienced companies.  CMG relies on 21 years of experience.  Many Times it is cheaper and more effective to install a French Drain over a Surface Drain.  A Surface Drain can’t move as much water as a French Drain, and a Surface Drain can’t Drain away Sub-Surface waterSurface Drains should be installed in areas where the Drainage Problem area is smaller and is not affected by sub-surface water.

The draw back to a French Drain, is that it is not a pretty as a Surface Drain.

French Drains do a great job running along foundations and driveways.  A French Drain will keep water away from cement and prevent damage to concrete if water should freeze up against it.  A French Drain can keep your foundation Dry.

Some Simple rules about French Drains and Surface Drains.  A French Drain should be installed when there is a large volume of water to be drained over a large area.  Surface Drains are needed when the water volume is smaller and the Drainage Area is small and focused.  French Drains move away Surface Water and Sub-Surface water.  Surface Drains move only surface water.

 

French Drain Design must take into account many variables.  One consideration for a French Drain that many times is missed, is the type of soil.  French Drain Design must take into account the type of soil that the French Drain runs through.  If the soil is “Tight or made up of Clay, A French Drain Liner may not be necessary.  The Gravel or Limestone that is used to fill the French Drain trench may be all that is needed to maintain the integrity of the trench over time.   This means that dirt will not mix in with the French Drain Gravel and clog it up over time.  This is not the case however if your soil is sandy or loose.  A Trench Liner should be used to prevent this type of soil from moving into the gravel of the French Drain.  Trench Liners are relatively inexpensive and are not hard to install.  If you are not sure what to do then install the Trench Liner in the French Drain.

 

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.

Today we installed a 6 Inch French Drain at an apartment complex near Lake Heffner.  The French Drain started in the back yard of one unit.  The Drain Pipe went under the fence and into the adjoining unit’s back yard.  The French Drain then looped around their patio and out under their fence to the west.  To get the 6 inch Drain Pipe to the correct Exit Point, we had to cut out 30 feet of sidewalk and run the French Drain Pipe under the sidewalk.  Next, we replaced the sidewalk with new concrete.  Finally, we dug a drainage ditch across the front yard to the parking lot.  We covered the Drain Pipe with sod that we carefully removed when digging the trench.  At the edge of the parking lot a 6 inch Pop-Up Emitter was installed to release the Storm water.  Seven Gutters were connected directly into the Drainage System along the way.

Edmond Oklahoma has been the location for many French Drain Installations for CMG in the past several years.  Recently we ripped out an old Surface Drain that was under a deck.  The Surface Drain was too small for the job and did not Protect the Foundation from Standing Water


 The First step was to take out part of the deck along the wall.  Next we took out the Surface Drain and the Three Inch Pipe which was too small.  Digging a trench along the foundation came next.  We had to ensure the, “Fall” to make sure the water would run from left to right. 


 Next a French Drain Liner  needed to be installed.  This was necessary to maintain the integrity of the trench and to keep the French Drain Pipe from filling up with sand and getting clogged over the next few years.  CMG then installed 4 inch ADS Perf/Soc French Drain Pipe along the course of the French Drain.  Next we connected the end of the French Drain Pipe to Solid 4 Inch ADS Drain pipe to continue along the trench to the Pop-Up Emitter at the Exit Point.

Connecting a gutter to a Drainage System

CMG installed a 4 inch French Drain in East Norman this week.  The customer had water standing on the side of his house that was causing foundation damage.  He contracted a Structural Engineer to come out and look at the Drainage Problem and to give him some advise.

The Structural Engineer recommended a French Drain to protect and draw water away from the foundation.  He said that, “he had recommended French Drain Installation to solve similar problems for home owners many times in the past.  The Structural Engineer was confident that it would solve the Drainage Problem.

Next, our customer went online and found us by searching under, ” Norman Oklahoma French Drain.”  He also checked us out on Angie’s List and Found that we were one of the highest ranked Drainage Contractors in the state of Oklahoma for installing French Drains.

The Gentleman gave us a call to set up an appointment.  CMG arrived on the agreed time and provided a ( Free- No Obligation- Drainage Diagnostic and Quote) We came out and looked at his Drainage Problem and designed a Drainage System to solve his, Standing-Water Problem.”  We also recommended a surface drain in a corner where water was coming off a steep part of the roof and overwhelming the gutter.

Installing a curb outlet for a French Drain in Norman

The customer let us know that he was ready to move forward.  We scheduled the Drainage System Installation for the following week.  When the scheduled day arrived, we installed the Drainage System.  The Drain was made up of a 6 inch French Drain running 30 feet along the East side of the house.  It curved around the corner of the house.  At that point a 12 inch Surface Drain was connected to the French Drain with 4 inch pipe.  The 6 inch French Drain at that point changed to 6 inch Solid Drain Pipe and continued under ground 65 feet to a pop-up emitter at the curb in the front yard near the street.

Problem solved!
