A French Drain is essentially a “path of least resistance” to channel water from one area to another. It is a drain rock-filled trench with a perforated pipe, covered by filter fabric. It captures water from the surrounding soil and provides the easiest path for the water to move away from the area towards the city’s storm drain or a more desirable dispersal area.

A simple french drain is straightforward to install and once complete, blends into the landscape over time.
