What Is a French Drain?
Managing water on your property is key to preserving your foundation, and keeping your grounds looking great. Whether you’re buying a new property, building a home for your family, or work professionally as a realtor, you may have heard the term “French drain” used to describe a certain type of drainage system. You may be wondering, what is a French drain and how does it work? Here’s the inside info on all things French drain-related from the experts at Align Foundation Repair.
How Does a French Drain Work?
A French drain uses a buried pipe to collect water and divert it to a place where it can be better absorbed into the ground. It is a specific style of yard drain that allows for broad collection of water. Relying on nothing but smart design and gravity, these drains feature a pipe with holes facing upwards. As the ground becomes saturated, water seeps in through the holes and collects in the pipe. At this point it can flow freely to lower ground. Align uses only PVC pipes for French drains, since they provide the best in both performance and durability. A smart, simple, and highly functional design that’s been in use for centuries all around the globe, it’s no wonder French drains are a popular water management solution throughout the American South.
How are French Drains Installed?
Installing a French drain is a fairly straightforward procedure. First a trench is dug from where unwanted water collects to where the property owner wants it diverted. This usually means digging a small trench from around foundation, driveway or lawn, to lower ground. Then a drainage pipe with openings cut along the top is installed. This pipe is often wrapped in a fiber cloth to prevent small debris from clogging the holes. Then the trench is lined with a combination of filler fabric and heavy mill plastic, and back-filled with gravel. In most cases, the gravel remains exposed to allow for both subterranean and surface collection.
Benefits of a French Drain
Water can damage foundations, cause mold problems in a crawlspace, or make outdoor areas muddy and unusable. A French drain is a great, low maintenance solution to this problem. Once installed, they need minimal upkeep. However, should your drain become even partially clogged, it’s effectiveness could be majorly diminished.
