French Drain Parts
French Drain Parts are a Drainage Trench, French Drain Trench Liner, French Drainpipe, Gravel or Crushed Limestone, Transition Drainpipe and Drainage Exit.
Drainage Trench
A Drainage Trench is where a French Drainpipe is located. The Drainpipe is placed in the bottom of the Drainage Trench. It needs to be in a low area where the water is standing or flowing toward.
French Drain Trench Liner

The White Material is the Trench Liner. The black material is the Pipe Filter.
A liner is placed in the bottom of the Drainage Trench. This liner allows water to enter the French Drain from the dirt surrounding the French Drain. Underground water, AKA “Sub-Surface Water, “can be drained away.
French Drainpipe
French Drainpipe is perforated. It is full of thousands of little holes. The holes allow water to enter the French Drainpipe. This can be Surface Water or Sub-Surface water. A cloth filter is wrapped around the pipe.
Gravel or Crushed Limestone
Gravel or Crushed limestone is used to fill the French Drain Trench once the Perforated Pipe is installed.
Transition Drainpipe
A Transition Drainpipe is a Solid Pipe that is connected to the Downhill end of the French Drain. It takes water away from the French Drain.
Drainage Exit
A Drainage Exit is a release point. This is where water leaves the Solid Transition Drainpipe.

French Drains can utilize several types and sizes of French Drainpipe. 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 Drainpipe are too few. Also, there is no filter or “Soc” around this particular French Drainpipe. 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 Drainpipe 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 Drainpipe. It works very well.
For Small business and Residential French Drains, four-inch ADS Perf/Soc French Drainpipe is adequate and the most common. It is used for the majority of all Drainage Systems.
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 gutters down spouts connected directly into the French Drain, For Example) Three Inch French Drainpipe should be avoided if possible.
6 Inch PIpe
Six-inch ADS Perf/Soc French Drainpipe is usually a good idea when possible. It carries a much larger volume of water. Six Inch pipes are rarely overwhelmed.

French Drain in Flower Bed in Edmond
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 Engineer
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.
Oklahoma Drainage has 30 years of experience Diagnosing Drainage Problems. We always check for sub-surface water flow into any Problem Drainage Area.

Don’t Do Well in Small Areas
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. They 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 homeowner has spent large amounts of money on foundation repair.

Several Foundation Repair companies and Duct waterproofing companies recommend Oklahoma Drainage for French Drain Installation. Typically, we install a French Drain by itself or as part of a Drainage System after they have completed their repairs to the foundation or duct work.
