Cold Joint Seepage & Leaking Floor Cracks
Other common areas for water seepage are the cold joint-the place where your foundation wall and concrete slab meet and cracks in the floor. When the ground around your home becomes saturated from heavy rainstorms or from a water table under the foundation, it increases the hydrostatic pressure. This pressure can force the water to seep in from the outside through the cold joint.
This hydrostatic pressure can also build up under the basement slab and force water through any cracks in the floor. Most often people loo to the simple fix: sealing the cracks. The problem with this “simple” fix is that the seal causes a dam like effect, which causes more pressure to build up under the floor.
