People have been struggling with water intrusion in basements for hundreds of years. The soils surrounding your home will settle causing voids in the soil. When these voided spaces are temporarily filled with rain water, it causes hydrostatic pressure. This pressure then pushes the water into the basement leaving you with a mess to clean up.
Why you may ask. Well, water will find the path of least resistance. When a basement is built, it is built out of concrete which is a porous material that most always has cracks, holes, and joints in it. These small openings allow the water to enter the basement through the walls, floors and joints. When water enters you begin to notice a more damp environment and begin to smell odors. If your basement is finished, it causes damage to your walls and floors.
No two homes are identical and that is why the best solution is one that is designed specifically for the conditions of your home, designed not to clog, provides a gap between your floor and your wall to drain wall leaks, and will not cause structural damage to your foundation.
Installing a customized interior sub-floor drainage system along the full perimeter of the floor as well as a pumping system is the most effective way to control the water intrusion in your home.
