If 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. Basements are often thought of as just places for storage that have concrete floors and walls where you can store old toys, tools and other stuff. The possibility of family rooms having extra space are realized.

Many homeowners go years without a water problem and then develop one due to the existing sub-floor and sub-surface drains clogging with mud.

The soil will become too saturated if water from the roof is not directed away from the foundation. As the home stabilizes, wall fissures appeared, exterior paintings decayed and the drains filled with sand or silt. Leakage in the basement can be caused by all of these problems. It is possible that flowing water on the ground enters the foundation through cracks or other openings; even solid masonry is not free from moisture as saturated soil enters through the walls as well as other openings. This is due to the natural pressure the soil exerts against the foundation. The higher the level of water, the greater the 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. The result is a flooded 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. Pressure builds up over time and moisture is pushed through the wall or floor. (usually called bleeding). Usually you’ll find seepage in corners or in joints where the wall meets the floor.

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 will go right through concrete since it is porous. 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. These can often be painted, rollered or sprayed on.

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.
- You must seal all joints between the walls and floor.
- Any cracks or joints noticed will need to be filled.
- Find out if it is necessary to use a primer and if it should be, prime the floor as per instructions
Spread two or three coats which is just right top-coating of the final product.

If you waterproof your basement floor with a good product the results should last for a number of years. There exist sealants in the market like PermaFlex which has lasting and durable basement floor waterproofing. 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.
