In the past 20 years, CMG has designed and installed a large number of Drainage Systems. For the most part, we have utilized French Drains and Surface Drains of many different shapes and sizes. In two decades we have built up a high level of experience diagnosing Drainage Problems. We know what to look for, what to expect, and how to approach a wide variety of situations where water is in a harmful or undesirable place.
CMG Sprinklers and Drains installs many types of Drains in a wide variety of places. Here are a few of them. French Drain Installation along foundations near walls – French Drain Installation behind retaining walls – French Drain Installation in and around flower beds – French Drain Installation in basements – French Drain Installation near sidewalks and along driveways – French Drain Installation under pool decks and around swimming pools – French Drain Installation on hillsides and on slopes to protect building and homes – Surface Drain Installation in sidewalks set in concrete – Surface Drain Installation in driveway set in concrete – Surface Drain Installation on side of house to catch water from gutter downspout – Surface Drain Installation in basement with Sump Pump inside to pump out the water – Surface Drain Installation in low spot in yard to handle a moderate amount of water – Surface Drain Installation next to driveway to catch water run-off – Surface Drain Installation next to sidewalk to catch water run-off – Surface Drain Installation connected to gutter down-spout – 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 the Drain 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. A Surface Drain may come in many different shapes or sizes. It is a Drain Basin with a Drain Grate on top and a Drain Pipe connected on the side. The Drain Grate may be round or square.

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.
