Often confused with a “trench” drainage system, a French drainage system is designed to stop surface and groundwater from sinking into your property’s earth and weakening your home or business’s foundation. It is essentially a small, gravel-covered trench that contains a perforated pipe. Conversely, a french drain is a trough-like structure that moves surface water away from your property before it has the chance to seep in.

French drain depth: About 8 inches to 2 feet deep should be sufficient for many water-diverting projects, though related systems, such as those built around foundations and sub-ground living spaces, as well as the bases of retaining walls, may be deeper.

A French drain starts with digging a trench. The depth and width of the trench can vary, but 5 to 6 inches wide and 8 to 12 inches deep are common sizes and usually satisfy most needs.

French drains are extremely effective at removing moisture from over-saturated soil. 

French drain installation costs can vary, but usually cost between $6,000 to $10,000 depending on the size of the basement and the amount of sump pumps that need to be installed.
