Waterproofing Basement Walls

It is possible to successfully waterproof your basement walls and floor. The steps you will need to take are dependent on the cause and severity of your moisture problem. Whether you plan to sell or occupy your home, addressing a moisture problem in your basement is a worthwhile investment. Moisture can cause damage to the structure of your home as well as your belongings. Additionally, dampness can result in the growth of mold which can cause a variety of serious health problems.

The steps required to waterproof your basement will be determined by the way that the moisture is entering. The first step is to locate the origin of the moisture. Some sources to consider include street run-off, faulty storm drains, a high water table, standing water due to a deficient slope, underground springs, or quite often, poorly functioning gutters. If ground water is a concern, you may need to install french drains or a sump pump. Contact your local public works department if you need help assessing the cause of your water problem.

The second step is to find the point or points of entry into your foundation. If there are no cracks or defects in your floor or foundation and you have mild seepage, the process may be as simple as applying a waterproofing product to the foundation walls and sealing the concrete floors. Begin by cleaning the surface thoroughly to remove dirt and any loose partials. Then apply a concrete or masonry waterproof coating as instructed on the label of one of the many products available.

Basements with cracks or defects require more attention to be successfully waterproofed. If a crack is wider than one eighth of an inch, it is recommended that you use a chisel to open up the crack in order for the hydraulic cement to bond. Make sure that the space you create is wider at the deepest level and narrower towards the surface. It is essential to prepare a crack or defect by properly cleaning it and removing any loose concrete. Fill the crack with hydraulic cement or another crack repair product. Follow the directions on the product label. After you have filled all the cracks you can then apply a water resistant concrete or masonry coating to your basement walls and floor.

If you have tried the above techniques and you still have moisture seeping into your basement, it is recommended that you contact a professional. We can’t stress enough the importance of having a dry basement.
