We install french drains in NJ. A french drain is a trench filled and covered with rocks or gravel that redirects ground and surface water from your property.
French drains are one of our most popular drainage solutions, as they are primarily used to prevent surface and ground water from damaging or penetrating building and house foundations.
The French drain system may also be used to distribute water, such as as septic drain field at the outlet of the typical septic tank sewage treatment system.
French drains are commonly installed behind or in retaining walls to relieve ground water pressure.
When installed correctly and applied to correct situations they can handle vast quantities of water for many years.
French drains are a time proven system for eliminating excess water. The earliest forms of French Drains were simple ditches, pitched from a high area to a lower one and filled with gravel. These were described and popularized by Henry French in his book Farm Drainage.
Today, specialized drain tiles are designed with perforations or holes to admit water. To prevent clogging gravel is placed around the perimeter of the drain tile to give water a path to the drain tile as well as filter soil particles.
With the development of geo-textile fabrics, gravel can now be surrounded with this fabric greatly enhancing its ability to filter soil. A French drain can be covered over with sod after installation, making them less conspicuous.
Over time the term French drain has developed numerous definitions and has been applied to many different products. It has gotten to the point that any piping that is buried in the ground is now called a French drain.
