Nobody wants to think about water in their basement, but when a leak occurs, it can be devastating to the home. Water saturates the ground and can enter the basement through cracks in the wall and floor. This causes damage to anything stored in the basement, but ultimately it can cause the foundation of the home to crumble.
Liquid Rubber Paint
Liquid rubber paint prevents water from seeping out of the walls and down to the floor. With a paintbrush or paint roller, you can apply it in the same manner as normal wall paint. This method is effective on basement walls that leak very little as larger amounts of water tend to build up behind the paint, cause large bubbles and then burst.
Epoxy Crack Filler
Painting over a cracked concrete wall with rubber paint does not stop water from entering the basement. You must replace or repair a cracked concrete foundation wall. The process of replacing a foundation wall is expensive, time-consuming and not always possible. Repairing the crack with epoxy resin filler serves as a viable alternative. Although repairing a crack does not address or fix the root cause of the crack, it does stop water from seeping into the basement.
One way to seal a foundation wall is with urethane. Urethane seals over the crack but does not extend to the outside of the wall. This allows water into the wall so it can filter downward and back into the ground. Urethane allows the wall to flex slightly when the temperature and humidity of the basement change. When this happens, the urethane flexes with the wall and does not crack. Urethane is considered to be a long-term cost-effective repair technique.
