How to Stop Concrete Floor Seepage

Concrete floor seepage occurs primarily when there is a large amount of hydrostatic pressure beneath the floor of your home. Continue reading to learn how to stop concrete floor seepage and how to keep a basement or concrete floor dry.

What causes concrete floor seepage?

When it rains, 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.

How to fix concrete floor seepage:

  1. In order to fix concrete floor seepage, you must first locate where the water is coming from; the floor, a cold seam or a crack.
  2. Once you've discovered the source of the leak, you need to repair any cracks with a concrete crack repair kit and seal the cold seam with a cold seam sealer.
  3. Lastly, seal the floor with a waterproofing concrete floor sealer.

In order to determine the moisture vapor emission of your concrete perform a calcium chloride test.
