Basement wall leaks were still a problem during heavy rains with the existing basement waterproofing system in this Clayton, Missouri home. We added our BrightWall® wall covering that looks like a finished wall and at the base we incorporated it into the existing wall flange.
The room addition in this Brentwood, Missouri house was built off a slab foundation and water was getting in from the patio and wetting the carpet inside. Our TrenchDrain® collected the water and drained it away from the home.
We use laser transits to determine how far a foundation wall is laterally moving inward. We can measure the inside wall and look for other visible signs of this problem. Typically, a poured foundation wall will tip in at the top of the foundation. See the 2nd photo of the exterior space between the siding and foundation wall of this O'Fallon, Missouri foundation. The Foundation SupportWorks® Geo-Lock™ wall anchors system solves this problem and is cost effective to do.
With a slab foundation the concrete floor is where the sill plate of a frame structure would be. When enough water can pool outside, the water can come directly in to the home and get on top of the slab. An exterior drainage system must be in place lower than the slab floor seam/sill plate and drained to a lower spot away from the building. In this case, it runs across the smaller section of a blacktop parking area near a garage.
Single sump pumps do not offer enough peace of mind if your home has a finished basement. Also, the open lid lets water vapor out and the increased humidity can help mold to grow. Our complete basement waterproofing system includes a WaterGuard® drainage system, TripleSafe® sump pump with sealed lid and battery backup pump. In this Oakville, Missouri home, we also installed the SaniDry® dehumidifier appliance, and BrightWall® giving the unfinished basement area a finished look, in addition to an IceGuard® discharge line and more.
