Water, while so essential to human life on Earth, can be ruinous when it leaks into your basement. Whether it comes in through the walls or the floors, water is responsible for the infamous musty and unpleasant smells that plague many basements and cellars. The smells, however, can be the least of your worries, especially when that moisture leads to mold and mildew build-up.

If you have built a new home, or recently have redone the concrete in your basement, it is relatively easy to prevent moisture seepage. However, if youve moved into a new home or it is too late to seal the concrete because moisture is already present, you have to take extra steps to fix the problem.

Moisture seepage occurs primarily when there is a large amount of hydrostatic pressure beneath the floor of your home. When it rains, the water is absorbed into the ground until the earth is too saturated to soak up any more water. At this point, the water will begin to rise to the surface, causing hydrostatic pressure to build up against your foundation and basement floors, which leads directly to water seepage into your home. When large amounts of hydrostatic pressure are combined with large pores on your concrete, especially if the concrete is poorly poured, the water will leak in at a much faster rate.

In order to fix water seepage, you must first locate where the water is coming from. Whether the leak is in the floor or in the walls, the process to remedy the issue is still the same. Once youve discovered the source of the leak, you need to repair the crack the water leaks through. This is best accomplished by using a concrete crack repair kit.

After using the kit and waiting the requisite time until the crack is repaired, it is crucial to seal the concrete surfaces in your basement. While the crack is technically repaired, it will not withstand water seepage indefinitely. In order to ensure that the problem doesnt return, you need to protect your concrete with a concrete sealer designed to penetrate through the surface of the concrete and block water from entering. Lithi-Tek 9500 is a good option for protecting your concrete floors from water and moisture seepage, while also preventing mold and mildew build-up. It is a penetrating sealer that will enter the concrete through the surface pores before reacting chemically within the material to block these pores for good.
