What is hydrostatic pressure?
Hydrostatic pressure is what builds up around your basement’s foundation and pushes water seepage into your home’s foundation. As water builds up in the pocket of porous soil around the exterior basement walls gravity pulls the water downward forcing water seepage into the basement.
How to relieve hydrostatic pressure:
To relieve hydrostatic pressure around a basement, you will need to tap into the source of the water by drill weep holes into the hollow cores of the bottom row of blocks. This will allow the water to drain, now you need to install a baseboard system that will collect the water and drain it to your sump pump. SealOnce Basement System an above floor channel baseboard system works on both poured wall and block wall foundations to relieve the hydrostatic pressure pushing against your homes foundation.
Block wall foundations have hollow cells that fill with water, which creates hydrostatic pressure. Tapping holes in each main cell will keep water from building up into hydrostatic pressure. With the SealOnce Basement System it’s not necessary to drill every cell available. Poured wall foundations do not have hollow cells, therefore, there is no need to tap holes into the wall. Poured wall water seepage comes in through the cracks in the wall and the cold joint where the floor and wall meet. Wall cracks should be sealed from the top down to within 4 inches of the floor.
