French Drains

Installing a drainage system is an integral part of basement waterproofing. French drains help you direct water away from structural walls, which can cause damage to your foundation, including cracking and crumbling.

The French drain was originally developed by Henry French. French improved upon existing drainage systems by eliminating the main problem with other water drains: clogging. French added crushed rock to a channel to prevent it from clogging with debris. The rock acts as a natural filter, allowing the water to move through the channel, but preventing soil, leaves and other organic matter from clogging the water’s path. This most basic drainage system design simply involved a dug trench, gravel and re-cementing the floor leaving a gap between the floor and the wall called the French drain. The trench should be sloped to channel the water to whatever point has been designated to handle the water collection, be it a sump pit, a dry well or simply a more appropriate water accumulation point.
