Methods for floor waterproofing of the basement
Many basement flooding and seeping problems could have been avoided by waterproofing the basement when constructed. Many people think basements are just concrete storage spaces for things you don’t use very often. The possibility of family rooms having extra space are realized.
After many years drains can become plugged with mud and causes water problems to occur.
The soil will become too saturated if water from the roof is not directed away from the foundation. As the home settles, walls crack, protective coatings applied to the exterior biodegrades and drainage systems fill up with silt. A leakage in the basement might result from all these problems. Flowing ground water enters through cracks or other openings in the foundation; moisture in saturated soil enters through solid masonry as well as through cracks and other openings because of the natural pressure the soil exerts against the foundation. The higher the level of water, the greater the pressure. As water pressure increases, water begins to seep into cracks in the concrete walls and floors. The end results are a water filled crawlspace or basement.
If you want to keep hydrostatic water from getting into your home, pressure relief systems will do the job for you. However when the electricity goes out, most likely during a rainstorm, primary pumps cannot work. Over time this pressure increases until the moisture is literally pushed through the floor or wall (usually called 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. However, concrete is porous and allows water vapor to pass through. 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.
Here are some examples of what a regular basement floor waterproofing project might entail:
- getting the floor ready by taking up any materials that are broken up or loose.
- Care has to be taken to see that the floor of the basement is absolutely dry,and for this one may need to hire large fans or heaters.
- Assuring that the wall/floor junctions are sealed off.
- Filling in all crevices and bends which are especially visible.
- Priming the floor when the product calls for the use of a primer.
- top-coating floor with the final product, using 2 or 3 coats as appropriate.
If you waterproof your basement floor with a good product the results should last for a number of years. Permaflex is one type of sealant that will give a complete and permanent waterproofing for a basement floor. Quoted as being the only indoor waterproofing system that completely seals any basement floor permanently, no matter how wet or deteriorated, seems a good easy system that costs a few hundred dollars as opposed to thousands for considerable manual work, pumps and pipes.
