Basement Floor Waterproofing MethodsIf basement floor waterproofing wasn't overlooked on such a regular
basis, then there wouldn't be as many problems with seepage and flooding
when it was finished. Many people think basements are just concrete
storage spaces for things you don't use very often. These days, many
individuals recognize that such an area can be used for other things
besides more bedrooms, living rooms and dens.
The water problem was not encountered in the beginning by homeowners, but it later appeared because sub-floor and sub-surface drains clogged with mud. The soil will become too wet and saturated if water from the roof isn't directed far away enough from the foundation. As the home stabilizes, wall fissures appeared, exterior paintings decayed and the drains filled with sand or silt. A leakage in the basement might result from all these problems. Natural pressure from the soil against the foundation will cause flowing ground water to enter through any cracks or crevices in your foundation. A high water level can create a great amount of pressure. In turn this water, under increased pressure, seeks entry through cracks and crevices in the walls and floors, and concrete is no match for water pressure. Without proper preparation, torrential rains could cause flooding in basements or crawlspaces. If you want to keep hydrostatic water from getting into your home, pressure relief systems will do the job for you. Primary pumps cannot work if the electricity goes out during a rainstorm. Pressure builds up over time and moisture is pushed through the wall or floor. (sometimes termed bleeding). Corners and joints that connect the floor and the wall are the most likely candidates for seepage. If water seems to be coming in from an isolated area, installing a sump pump below floor level can lower the water table and underground hydrostatic pressure in that area. Water vapor passes through porous concrete. This moisture makes it feel even colder, causes carpet or other floor covering to rot, allows mold to grow, and causes the basement to smell musty. One solution is to use one of the high-grade sealants that are available on the market for the home-owner. Frequently, they can be applied with a brush, roller or spray can.
