Many basement flooding and seeping problems could have been avoided by waterproofing the basement when constructed. A basement can be so much more than just a convenient place for storing junk! Now, people realize the potential of this space for something much more such as extra living space, family rooms and bedrooms.

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. A leakage in the basement might result from all 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. 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. The end results are a water filled crawlspace or basement.

Pressure relief systems are a good way to prevent hydrostatic water from entering your home. Whenever there happens to be a power outage due to a rainstorm, it is very likely that the primary pumps will not work, and that may cause somewhat of an inconvenience. Over time this pressure increases until the moisture is literally pushed through the floor or wall (sometimes termed 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. However, concrete is porous and allows water vapor to pass through. A wet or damp basement due to excessive moisture will cause carpeting to rot, allows mold to grow and makes the basement smell musty.

Using high quality sealants easily found in the marketplace is a good remedy. It is often possible to paint them with either the roller or spray method.

A normal basement floor waterproofing job may 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.
- Priming the floor when the product calls for the use of a primer.
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. This indoor waterproofing system claims to permanently seal you lower level floor at considerably less cost than other systems.
