Waterproofing techniques for basement floors.

Why is basement floor waterproofing so often overlooked, when if it was done when the basement was built, there would be fewer problems with seepage and flooding? 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. These days, many individuals recognize that such an area can be used for other things besides more bedrooms, living rooms and dens.

Water situation 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 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. Leakage in the basement can be caused by all of 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. The level of pressure is positively correlated with the height of the water level. As water pressure increases, water begins to seep into cracks in the concrete walls and floors. The result is a flooded crawlspace or basement.

A pressure relief system can eliminate water that leaks into your basement. 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. As pressure increases the floor or wall will be penetrated by moisture. (sometimes termed bleeding). Seepage is often found where the wall meets the floor around the corners and joints.

If water come from an isolated area and is installed a pump below the floor level will lower the water and the underground pressure However, concrete is porous and allows water vapor to pass through. Because of moisture it feels even more cold, and rots carpet and other floor coverings. Even the mold starts to grow and basement smeels musty.

Using high quality sealants easily found in the marketplace is a good remedy. Frequently, they can be applied with a brush, roller or spray can.

A normal basement floor waterproofing job may entail:

- preparing the floor by removing crumbly or loose material.
- 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.
- making sure wall/floor junctions are sealed.
- filling any particularly noticeable cracks or joints.
- Find out if it is necessary to use a primer and if it should be, prime the floor as per instructions
- Use 2 to 3 coats as needed to top coat the floor with the final product.

A high quality product will result in basement floor waterproofing that can last for years and years. There exist sealants in the market like PermaFlex which has lasting and durable basement floor waterproofing. This is arguably the only waterproofing system that is suitable for indoor use that will result in the complete sealing of a basement floor, no matter what sort of state it might be in. And it is considerably cheaper than other type of work as it does not involve pipes or pumps!
