How To Address Wet Basement Flooring

Posted on: 31 March 2020

Standing water on your basement floor can be a major issue. The problem usually stems from a combination of factors -- a high water table compounded by rain and poor drainage combined with leaks in the basement floor itself. Leaks tend to occur first around cove joints and cracks in the floor. Fortunately, there are some waterproofing strategies that can solve the problem.

Drain Tile Systems

You may not be able to do anything to counteract a high water table, but you can ensure the water doesn't end up in your basement. The installation of a drain tile system in your basement floor is the most effective way to deal with the leak. Your waterproofing contractor will dig trenches in your basement floor and then install perforated pipes, known as drain tiles, in these trenches. Then, concrete is typically poured over the top of the tiles. As water percolates out of the ground, it enters the drain tiles and is promptly routed away from your home. This prevents the water from putting pressure on your basement foundation and causing leaks.

Sump Pumps

Not all water will drain out as desired, even with a drainage system. This is where a sump pump can help. Pumps are needed when water comes into the basement too quickly for the drain tiles to route it away. They are also useful if your home is in a low area that makes it impossible to route water away from the foundation through the drains via gravity. The waterproofing contractor installs a pump trench (sometimes called a sump pit) and routes the drain tiles to this pit. The pump sits in the pit and turns on when the water sensor is tripped. This way the pump can move the water out of the basement more quickly. Most homes only need one sump pit to handle the issue.

Crack Injection

Injecting cracks with an expanding polyurethane seal can render the crack waterproof, which is why this method is often used on basement walls. Unfortunately, it will only have limited success on a basement floor because the pressure of the water beneath the floor will eventually cause new cracks to form. That doesn't mean that crack injection shouldn't be used on floors, though. Instead, crack injection is used to fix floor damage after a viable drain solution is installed, such as drain tiles or a sump pump.
