A French drain is a type of drainage system designed to redirect water away from a specific area. It typically consists of a perforated pipe that is surrounded by gravel or other porous materials and installed in a trench filled with gravel or crushed stone. The trench is sloped to direct water toward the perforated pipe, which carries it away to a designated drainage area.
French drains are commonly used to address issues with standing water or excessive moisture in basements, crawl spaces, yards, and other outdoor areas. They can help prevent water damage to buildings, prevent soil erosion, and promote healthier plant growth.
The term “French drain” originated in the early 19th century, when Henry Flagg French, a farmer and lawyer, first described the system in a book on farm drainage. The term has since become widely used to describe any type of drainage system that uses a similar design.
French drains can be installed by a professional contractor or as a DIY project, depending on the complexity of the installation and the specific needs of the area. A professional contractor can help determine the appropriate size and design of the drain based on factors such as soil type, slope, and drainage needs.
