The causes of a wet basement

Did you know you can have water issues in your basement without heavy rains or obvious standing water? It's easy enough to see water coming through a crack in your floor or basement wall, but what's the real cause of your basement water problem?

The Clay Bowl Effect

Excavated soil that's replaced around a completed foundation isn't as dense and tightly packed as undisturbed soil farther away. As a result, water collects in the soil immediately surrounding the house, putting pressure on foundation walls and causing cracks.

Hydrostatic Pressure

The weight of the water in the soil around the foundation exerts pressure, forcing the water through cracks, gaps, holes, and around windows leading into the basement.


How we solve your basement waterproofing problems

Effective water removal & protection. Clog-free drainage, a powerful sump pump, and efficient dehumidifier provide the ultimate dry basement solution.
