Hydrostatic pressure is the weight of water when it’s at rest. It is a big source of foundation problems and basement waterproofing problems. Poor drainage, clay soil, underground water sources and extreme weather all contribute to hydrostatic pressure.
The water collecting around your foundation has to go somewhere. And if the footing drains are clogged, then the water can go into your basement. The hydrostatic pressure pushes against your basement foundation and will eventually cause cracks, leaks, acid damage and other problems.
