What Is an Interior Drain?

An interior drain is a kind of drainage system for basements. They’re incredibly efficient in stopping water from flowing into your basement. With interior drains such as these, any kind of water that makes its way in will be redirected towards the sump pump and pumped out and away from the foundation. First, contractors dig a trench along the perimeter of the basement and then filled with some gravel. The drain pipe is then placed on the gravel and the floor is restored once everything is in place.

The soil that surrounds your basement is constantly saturated with water. Because basements are partially underground, they are constantly exposed to all the moisture from the soil, which can seep through the porous concrete and humidify your basement. With an interior drain installed, any moisture that appears on the walls of the basement trickles down into the drain, accumulates, and gets pumped out instead of staying in the space and contributing to the humidity. An interior drain works best when accompanied by a sump pump, so if you’re thinking of getting this kind of drainage system for your basement, you need to get a working sump pump if you don’t have one already. At Tar Heel Basement Systems, we have the BasementGutter™, an award-winning interior drain for your basement.

We also have AquaGrate™, which is a drain that can be installed at the entrance of your basement. Not all the water in a basement comes through the walls. Sometimes, water comes in from the outside. When that happens, you can count on AquaGrate™ to collect the water and redirect it elsewhere. With these two drainage systems in place, you no longer have to worry about basement flooding.
