Despite the name, French drains are the product of American ingenuity. The first examples were developed by Henry Flagg French, a lawyer and farmer who lived in Concord, Massachusetts in the mid-1800s. Today French drains are used in many forms and go by different names, too. The French Drain System from Basement Systems is a collection of patented products that work together to keep basements dry.
A French drain is sometimes also referred to as drainage tile, a rubble drain, a perimeter drain or weeping tile.
Clog-free drainage. Drain lines installed outside the foundation or in the “mud zone” eventually clog and stop working. The French drain system installed by Basement Systems won’t clog because it’s located in the “clear water zone” above the basement wall footing.
Wet weather saturates the soil outside your foundation. Water pushes against your basement walls just like the ocean pushes against the hull of a boat. This high hydrostatic pressure means that even a small leak can admit enough water to flood your basement.
French drains can lower hydrostatic pressure by providing ground water with an escape route. But as shown in the drawing, French drains installed in the “mud zone” or outside the foundation are easily clogged with silt, mud and plant roots. Basement Systems’ WaterGuard® drainage system won’t clog because it’s located in the “clear water zone” above the footing. It’s the best way to relieve hydrostatic pressure and keep the basement dry.
