Basement Interior Waterproofing
Basement interior waterproofing involves the installation of an interior drainage channel that will run along the inner boundary of your basement floor. This channel will collect the water that enters your basement by way of any cracks and crevices in the walls and floor. The water is then drained into a sump pump and pumped away from your property.
We then use a dehumidifier to control the humidity of your basement and prevent rotting, mold and mildew buildup and get rid of dust mites.
Along the affected area we remove a section of concrete. Once we have exposed the work area we clean the trench of any debris. Then we install a 4″ corrugated perforated pipe covered in a soil separating sock. Then we install gravel to keep the pipe from shifting. After the pipe is installed, we install a bead board on the wall to allow any moisture to enter the pipe under the concrete. Finally, we reinstall the concrete over the pipe.

Common Questions About Interior Basement Waterproofing
What happens during an interior waterproofing installation?
We remove a section of concrete along the affected area and clean the trench of debris. Then we lay a four inch corrugated perforated pipe wrapped in a soil separating sock, and pack gravel around it so the pipe does not shift. We install bead board against the wall so moisture coming through the block can reach the pipe underneath the floor, then we pour the concrete back over the top.
What is the sock around the pipe for?
It keeps soil and fine sediment out of the perforations. Without it, the holes that let water into the pipe gradually silt up, and a clogged drain does not drain. The sock is what keeps the system working years down the road.
Where does the water actually go?
The drainage channel carries it to a sump pump, and the pump moves it away from your property. The system collects the water that comes in through cracks and crevices in the walls and floor and gets it out before it can stand in the basement.
Do I need a dehumidifier as well?
We use one to control the humidity after the drainage is in. Getting the standing water out is the first job. Bringing the humidity down is what prevents rot, mold and mildew buildup, and dust mites, and that takes a dehumidifier in most basements.
Is interior waterproofing less disruptive than exterior?
Generally yes, because the work stays inside and we are not excavating around the house. The trade-off is that interior work manages water after it reaches the wall rather than stopping it outside. Both approaches are valid. Which one fits depends on how water is entering and what access we have around the foundation.
