How to Build a Linear French Drain
French drains, though their name indicates differently, were developed in the United States. They primarily operate by supplying invasive groundwater with a path of least resistance by which it can be redirected away from a basement or low-lying section of lawn. They are named after a new Hampshire man, Henry Flagg French, who, in 1860, published a volume with the inviting title: “Farm Drainage – The Principles, Processes, and Effects of Draining Land with Stones, Wood, Plows, and Open Ditches, and Especially with Tiles.”
