How To Seal Bottom Of Basement Walls

Basement flooding is a common problem for homeowners, and it can cause serious damage to your home and belongings. Water can seep into your basement through cracks in the walls, floors, or foundation, and it can also enter through windows or doors. If you have a basement, it is important to take steps to seal the bottom of the walls to prevent water from entering.

There are a few different ways to seal the bottom of basement walls. One option is to apply a hydraulic cement patch to the cracks. Hydraulic cement is a type of cement that expands when it is wet, and it can be used to fill cracks and seal leaks. To apply a hydraulic cement patch, follow the manufacturer's instructions. Be sure to clean the crack thoroughly before applying the patch, and allow the patch to dry completely before sealing it with paint or caulk.

Another option for sealing the bottom of basement walls is to use a polyurethane sealant. Polyurethane sealant is a type of sealant that is resistant to water and moisture. To apply a polyurethane sealant, follow the manufacturer's instructions. Be sure to apply the sealant evenly to the crack, and allow it to dry completely before sealing it with paint or caulk.

If you have a large crack in the bottom of your basement wall, you may need to use a more permanent solution, such as a sump pump. A sump pump is a device that pumps water out of your basement. Sump pumps are typically installed in a sump pit, which is a hole in the floor of your basement. When the water level in the sump pit rises, the sump pump will turn on and pump the water out of the basement. Sump pumps can be a very effective way to keep your basement dry, but they can be expensive to install and maintain.

If you are not comfortable sealing the bottom of your basement walls yourself, you can hire a professional basement waterproofing contractor. Basement waterproofing contractors have the experience and expertise to seal your basement walls properly and prevent water from entering your home.

Here are some additional tips for sealing the bottom of basement walls:

Inspect your basement walls regularly for cracks or leaks. If you find any cracks or leaks, seal them immediately.
Keep your gutters and downspouts clean and free of debris. This will help to prevent water from pooling around your foundation and seeping into your basement.
Grade your yard away from your foundation. This will help to prevent water from flowing towards your foundation and seeping into your basement.
Install a sump pump in your basement if you have a history of basement flooding. Sump pumps can be a very effective way to keep your basement dry.
