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.

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.

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.

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.

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.
DECORATIVE STONE CAN BE USED TO COVER A FRENCH DRAIN AND THEY LOOK GREAT AND LAST A LIFETIME.

Sprinkler System Installation in Oklahoma can be complicated.   There are many details that very important to ensure that a new Sprinkler System be durable and dependable for many years to come.  Attention to detail makes all the difference when installing a Sprinkler System.  Many times, So-Called, ” Fly By Night Sprinkler Companies,”  cut lots of corners to save money.  Low price should not be the determining factor for having a Sprinkler System installed.  A cheap Sprinkler System soon becomes very expensive if it has to be fixed all the time or won’t work at all.

Two things you should require on any Sprinkler System:

1.  Make shure PRIMER  is used along with PVC Glue when the Sprinkler Pipe is put together.  Primer helps the glue to bond to the PVC pipe.  This ensures that all the pressurized pipe connections won’t leak over time.  I have seen Sprinkler Systems that were no more than a year old that leaked everywhere.

2.  Make shure the connection for the Sprinkler System at the water meter is done with a, “compression T.”  This ensures that no leaks will occur over time at this connection.  The Sprinkler Connection at the water meter is highly stressed every time the Sprinkler System is turned on.  A connection with Glue and Primer will not hold up to the stress over time.  This is why a Compression T must be used.

The above two points are just a few of the details that need to be considered when installing a Lawn Sprinkler System.

For twenty years, CMG has been paying close attention to the important details necessary to ensuring the Installation of Sprinkler Systems that are dependable and will last.

My name is Blane Callen. I have owned and operated CMG Sprinklers and Drains since 1993.  I take great pride in my work.  The Letters “CMG” stand for the first letter of the first name of each of my children.  ( Chance, Melissa, Garrett )  = CMG

I have amassed a great deal of experience designing and installing Sprinkler SystemsRepairing Sprinkler Systems, and designing and installing Drainage SystemsIn the past 19 years, I have made mistakes, but I have learned from them.  As a result I get calls, from time to time,  from other Sprinkler and Drainage companies that have run into a problem that they can’t handle.  I am always glad to help.

I usually don’t take money up front for Sprinkler Installation, Sprinkler Repair, or  French Drain Installation.  I prefer that the customer pay me when the job.  In a few cases on very large jobs I request a draw or outlay for parts.  The parts are delivered from my supplier to the address where the job is being done and equal the amount of the draw.  The parts stay on the premises until they are installed.

 


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)

French Drain Running Through Low Areas in Yukon

French Drain Running Through Low Areas in Yukon

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.

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 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.

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.

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.

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.

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!

Oklahoma City is one of the communities in  Oklahoma that CMG services.  We have installed almost a thousand French Drains in the Oklahoma City community in the past 21 years.  Oklahoma City  has many hills and valleys.  Many Neighborhoods are built on hillsides.  This causes many Drainage Problems.  CMG has installed French Drains by themselves and as a part of Drainage Systems to protect Driveways, Sidewalks, Foundations all over Edmond.  French Drains may be installed in Flower Beds or grassy areas too.  French Drains when installed correctly can provide many years of property protection and Piece of Mind.

 

CMG has 21 years of experience installing French Drains, and Drainage Systems.  This ensures that a Drainage System that we install won’t have Drain Pipes that are too small, or Surface Drains installed where French Drains Should be placed, or Exit Points that allow water to Stand and become stagnant.  CMG relies on 21 years of experience to Diagnose a Drainage Problem.   Many Drainage Problems are not as simple as they seem.  Understanding why a French Drain should be installed over a Surface Drain in particular situations is just one of many variables that must be considered when Diagnosing a Drainage Problem.

Many times CMG is asked to look at Drainage Systems that aren’t working correctly.  Here are a few common problems that we find:

French Drain Pipe is too small for the Drainage Area.

French Drain is not connected to an Exit Point.

French Drain is installed where a Surface Drain is needed.

Surface Drain is installed where a French Drain is needed.

Too many gutters connected to French Drain.

French Drain covered with dirt.

Exit Point Covered with Dirt.

Water flow is bad for French Drain,  (trying to drain water up hill)

These are just a few of the Problems we are asked to solve when fixing a Drainage System that wasn’t designed correctly.

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.

Here is a description of other recent work.

A little bit North of Downtown Oklahoma City CMG installed a 6 inch French Drain between two businesses which were less than three feet apart.  The French Drain went between a Law Firm and a Tire shop.  Water was leaking through the walls of both businesses.  Gutters between the two establishments were dumping a huge amount of water.  CMG installed a 6 inch French Drain between the two.

French Drain connected to gutter

It took a long time to get the dirt out of the trench for the French Drain.  It was a very tight fit.  We had to use a little red wagon to haul out the dirt for the French Drain and haul back in the crushed limestone for the French Drain.  It looked a little silly, but it was the only thing we could find that was narrow enough to fit between the buildings.  A French Drain that normally would take 1 day to install took three.

Curb Outlet for French Drain

The French Drain had a Double Exit Point.  This means that once water entered the French Drain Pipe, it could run South to the street or it could run North to the alley.  To exit points greatly increases the water capacity for any French Drain.

Along the course of the French Drain, we connected two large gutters directly into the Drain Pipe.

Once in place, the French Drain eliminated all the water that was leaking into the two buildings.

Drainage Problem Solved!

 

 


 

Many people ask us what the rocks in a French Drain are for?

 

The small rocks on the trench in the picture serve many purposes for the french drain. First and foremost they collect surface water and allow it to flow into the drain pipe. A secondary purpose the rocks serve are they act as a filter for the pipe and keep any form of dirt or debris from clogging the pipe and reducing the effectiveness of the drain.  Third, the rocks maintain the integrity of the drainage trench, keeping the surrounding dirt from collapsing  onto the perforated pipe.

This is an example of the drain pipe used in our drainage systems. In this picture we used the perforated ads drain pipe. It is covered by a black sock to help keep dirt out of the Drainage  System. It was connected on two sides by what we call a “T” to allow a gutter downspout to be connected into the Drainage  System. You can also see at the top of the picture what the final product looked like when the system is covered by the small pieces of limestone.

 


FRENCH DRAIN, DRAINAGE SYSTEM, OKLAHOMA CITY, EDMOND, NORMAN, YUKON

 

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.

After Diagnosing a Drainage Problem in Oklahoma City, We installed a 6 inch French Drain that went all the way around the pool in the back yard and then ran all the way to the street on both sides of the house. The French Drain made the shape of a horse shoe. The Drainage System had two Curb Outlets installed through the curb at the street. This gave the French Drain two different directions to allow the water to flow to the street.  Two Drain Outlets allowed the French Drain to move a huge amount of water during heavy rains.   A few weeks  later we got a call from our customer after a heavy rain.  She was very happy.  The French Drain did a great job protecting her pool.  All the Storm Water was diverted around the Swimming Pool.

French Drain installation is a big focus for CMG during our 21st year in business. A French Drain is one part of a Drainage System.  A French Drain can be connected to other types of Drains or Gutter Down-Spouts and then run through Drain Pipe to an Exit point where the water is released.

A Drainage Exit Point is the area where water goes to be released when it comes out of the Drainage System. The two most common exit points for a Drainage System are a Pop-Up Emitter or a Curb Fitting.
A Pop-Up Emitter is a Fitting on the end of a Drain Pipe that has a lid that pops up and releases water. When water drainage is complete, the lid shuts back.

CMG Installed a Double Six inch French Drain in Edmond this week.  A Double Six Inch French Drain is two six inch French Drains laid side by side in one very wide and deep trench.  It is designed to move a huge amount of water away from a home.   The CMG customer had several different drainage problems in their back yard.  After a thunderstorm, water would run under their back fence and into their garage.  The back yard was on a steep hillside and the water would run very fast down the hill and into the garage.  CMG installed 2 large six inch French Drains across the water’s path.  This allowed the water to be diverted into the French Drain which then ran through drain pipe to a curb outlet at the street.  Three Gutter Down Spouts were connected into the French Drain.  The French Drain created a protective barrier for the garage.  A 12 inch Surface Drain was also included in the Drainage System.  It was placed up against the driveway and connected with 4 inch Solid drain pipe to the 6 inch French Drain.  Water was completely rerouted away from the home.  A French Drain  and Surface Drain combination in this case was the best solution to this particular drainage problem.
