B-Dry® Systems Installation

Residential Waterproofing Services

The B-Dry® System is installed in a trench under the perimeter of the basement floor so that it picks up water about 8-12″ below the present floor surface. The trench is rough cut to enable the new cement to bond best to the existing floor. Before the system is re-cemented, a rigid vinyl barrier is attached to the base of the foundation wall to divert wall leakage down into the floor drain system. This is done when there is a poured concrete foundation. When the foundation is fieldstone, we install a flexible barrier that follows the contour of the stones directing any wall leakage into the system. Should you have finished walls (paneling or wallboard) we cannot access the foundation in order to install the rigid sealer, therefore an open stone moat is left behind your wall. The new cement over the B-Dry® System will dry to a light gray color.

As the water rises under the floor, it is picked up in the drain pipe system and drained by gravity to the sump well in which we install the pumps and covered with a plastic snap-on lid. Seepage from wall imperfections will run down the wall and behind the rigid sealer into our system. Whenever enough water has been collected in the sump well, an automatic electric sump pump empties the well in about 15 seconds, it then shuts off, and repeats the process as necessary. The pump operates only when the water level is high enough to trigger the float that activates the pump; therefore, it uses very little electricity. We normally install two electric pumps with every job, one as a back-up. Both pumps will pump at the same time only when necessary.

We normally install two electric pumps with every job, one as a back-up. Both pumps will pump at the same time only when necessary. We offer at additional cost the option of a battery back-up (power inverter and deep cycle marine battery) allowing the pump to work when there is a power outage.

The well and discharge line must be located in the best possible location for maximum output of water. The normal discharge of water from the pumps is to outside on top of the ground. No one can stop water or make it disappear; it must be redirected. When the water is table high, there could be puddling outside on the ground.
