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 Drainpipe is connected underground to an outlet on the Drain Basin. Stormwater Drains through the grate into the Drain Basin.  Once in the Drain Basin, water travels out of the basin through a Drain Pipe.  The Stormwater continues downhill in an underground Drainpipe to an exit point.

THIS IS NOT A FRENCH DRAIN!

A 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.

A Channel Drain is a type of Surface Drain, and many times is installed in concrete across sidewalks or driveways.

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.  The Drainpipe should have a neoprene sock around the Perforated Drainpipe.   This is to ensure that the Drainpipe does not become clogged.

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 Drainpipe 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 Drainpipe 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.
