Using the best products available for basement wall repair greatly affects the success of any project. Carefully choose the right products for your needs. The basement wall repair products you use will depend on the type of damage your wall has sustained.


Small cracks in your basement wall are typically nothing to worry about, but they need to be patched all the same. These small cracks are generally caused by the house settling over time. If any of the cracks are growing, or if they always seem to re-crack, contact a professional to help.

There are several techniques for fixing cracks in basement walls. The easiest is to scrape the debris from inside the crack using a chisel or similar tool. Make the crack wider at the top than at the bottom to keep the mortar in place. You can then fill the crack with hydraulic cement, which will expand slightly as it dries. Hydraulic cement is very easy to apply, as it requires no specialist equipment.

Another technique used to fix basement wall cracks is applying epoxy resin. Epoxy is either a natural or synthetic mixture of chemicals that hardens. The mixture can be injected directly inside the crack to fill the porous areas of concrete.

Bowing Walls

If your basement walls are bowing, they need careful consideration. The best method of correcting bowed walls is to use steel beams that are mortared directly into the walls. Doing so reduces the load on your bowed walls and should prevent the problem from becoming worse.

Bowing walls are a cause for concern. If you are concerned or not confident that you can complete the job yourself, you must call a professional.


Another cause of basement wall damage is excess moisture within the walls. If that is the problem, you have two main options for waterproofing the basement walls. Remove any drywall and everything else from the surface of your walls.

Once the concrete block is exposed, apply a vapor barrier or drylok paint to seal the walls. A vapor lock is a sheet of rubber that you can fix directly onto the wall; drylok is a special type of paint that you can paint on to seal the walls. After sealing the walls, replace the wall coverings so that nobody can see what you've done.
