Oklahoma Drainage and Sprinkler Repair – We have over 27 years of experience solving all types of standing water and drainage issues. 

 

Since 1993 we have installed over 2000 Drainage Systems in Oklahoma.  Over the years we have utilized French Drains, Surface Drains, and Channel Drains as important parts of Drainage Systems.

A Drainage System has 3  Parts, an “Intake” A “Transition”, and an “Exit.”

The Intake is where water is taken in to the Drainage System.  This is done with a French Drain, Surface Drain, or Channel Drain.  There may be several intakes in one Drainage System depending on the Drainage needs.

The Transition is simply the pipe that takes the water to the Exit Point.

The Exit point is the place where the water leaves the Drainage System.  Typically through a “Pop Up Emitter” or a ” Curb Outlet.

 

Standing water can cause many types of property damage ranging from foundation problems to cracked sidewalks and dead plants and shrubs.  If you have need of French Drain or Surface Drain, give us a  call.  We provide free estimates for all of central Oklahoma.

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 Drains are one kind of Surface Drain that we install in concrete.

The most common Drain that we install is the French Drain.  This is because the French Drain is versatile.  It can handle Surface Water Problems or Underground Water Problems (sub-surface).  A huge mistake that many people make is assuming that water gets to a Problem Drainage Area by flowing over the surface only.  For example, if water is flowing down hill underground toward your home’s foundation, the only way to stop or intercept it is with a French Drain.  Water can flow laterally into a perforated French Drain Pipe.  It is then diverted away from the Problem Drainage Area to an Exit Point.

Pop Up Emitters can release water from Surface Drains or French Drains.  They can release water on to sidewalks or driveways, or out in the middle of yards.

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.

When we run Drain Pipe across yards to an Exit Point, the sod usually can be put back into place and in a few days you can’t tell a French Drain was ever Installed.
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 French Drain.  In some cases thick grass growing up through the French Drain will create a natural “Thatch” filter.  This makes the French Drain invisible.  The trick is to allow the grass to grow over the French Drain Gravel without covering it up with dirt.  Grasses such as Bermuda which grow well in the sun will put out runners and new roots and will grow up and through the French Drain.  This will not affect the performance of the French Drain.  The problem is that some times depending on the type of soil involved, it may take a long time to completely cover up the French Drain.  Sprinkling grass seed down in the gravel will speed up the process.

DON’T 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.

Oklahoma Drainage and Sprinkler Repair 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, we 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.

Recently we had a customer call us with a drainage problem.  She had water standing in front of garage door.  If it got high enough it would run into the garage.  We installed Surface Drains in the Driveway in front of the garage door in the concrete.  The Surface Drains had metal grates and could easily support the weight of a car once the concrete had cured.

Standing Water can cause all types of problems in and around homes in Oklahoma.

We use several types of drains to solve several types of  drainage problems.  Oklahoma Drainage and Sprinkler Repair utilizes French Drains, Surface Drains and Channel Drains.

Oklahoma Drainage and Sprinkler repair can help.  We can put a Drain in a Driveway, or fix a leaking Sprinkler Valve.

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.

Standing Water

Do you have water standing in your yard after a hard rain? Does your sidewalk become a moat during a thunder-storm? Is standing water causing your foundation to deteriorate and break down? Is water seeping into your home and causing mold?

Storm-water run off can cause many types of problems. Oklahoma Drainage and Sprinkler Repair can diagnose your drainage issues and design a Drainage System to fit your specific needs. We install many types of drains including: French Drains, Channel Drains, Surface Drains, Basin Drains, Trench Drains, Basement Drains, and Sump Pumps.

Water can cause damage in all kinds of places.  A Drainage System, simply put, is a Drain with a Drain  Pipe leading underground to an exit point.  Most Drainage Systems utilize a French Drain or a Surface Drain, or both.

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!

If you have problems with Standing Water after a hard rain, or your driveway or sidewalk turns into a moat after a thunderstorm, or worst of all, you have water standing against your foundation and seeping into your house and vents, Give CMG a Call!  TYPICALLY A DRAINAGE SYSTEM IS MUCH LESS EXPENSIVE THAN FOUNDATION REPAIR OR REMOVING MOLD FROM YOUR HOME OR BUSINESS!!

FRENCH DRAIN, SURFACE DRAIN PHOTOS AND INFORMATION

This is not a French Drain

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 Basin.  Storm-Water Drains through the grate into theDrain 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!

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.

This is a French Drain

 Many people confuse the two types of drains.  No problem, we install both.

Standing water can cause many types of property damage ranging from foundation problems to cracked sidewalks and dead plants and shrubs.  If you have need of French Drain or Surface Drain, give us a  call.  We provide free estimates for all of central Oklahoma.
