What is a French drain system?

As the name suggests, a Terryville, NY French drain basement system is a type of drainage system for a basement. While there are several types of basement drains, the French drain system is one of the most widely used and recommended among experts in Suffolk County.

Introduced decades ago, the French drain system is a trench that’s filled with rocks and gravel. The rocks and gravel filter sediment and dirt out of the water. A perforated hollow pipe may also be placed along the bottom of the trench to collect and channel the water away from the basement. The coarsest grains of rock and gravel is situated in the center of the trench, while the finer grains line the outer layer. Arranging the gravel and rock in this way prevents the drain from clogging.

There are two different types of French basement drain systems: an interior French drain and an exterior French drain. The primary difference between the two types is where they are placed; however, both are relatively similar in terms of function, and both are highly effective.

What is an interior French drain?

An interior French drain is installed within the basement along the perimeter of the interior walls of the foundation. In existing basements, concrete is removed down to the footing of the house, a layer of stone is laid, and a perforated pipe is placed along the top of the stone. Any water on the floor joint of the basement wall will be collected in the drain, and a pump will remove the water that has been collected out of the house.

Benefits of an interior French drain

Interior French drain systems offer specific benefits over the exterior French drain. These benefits include the following:

What is an exterior French drain?

Exterior French drains are similar to interior French drains; however, as the name suggests, rather than being installed along the interior perimeter of the basement walls, it’s installed along the exterior perimeter of the foundation. This drainage system consists of a flexible, perforated drain pipe, which is buried in a trench along the bottom of the foundation footing of your Suffolk County foundation. Again, gravel and rocks are installed around the pipe, and landscaping fiber may also be installed, which will filter out the sediment and dirt from the water.

As water pools around the exterior walls of your home’s foundation, it will filter into the pipes of the exterior French drain system. A sump pump or gravity can be used to drain the water away from the trench. In order to use gravity, there must be a relatively steep incline in your property, otherwise, it will not drain efficiently. Exterior French basement drains are a popular choice for newly constructed homes in Suffolk County.

Benefits of an exterior French drain

Some of the most notable benefits of an exterior French drain system include the following:

Which Terryville, NY French drain basement system should you choose?
