- 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.
