Basement wall cracks

Believe it or not, basement problems such as cracks in poured concrete walls are very common. Most basement wall crack repair is necessary due to the shrinkage attributed to the concrete curing process. Often times, you will see these types of cracks located in the middle third of the wall or from the corner of a window. However, many of those cracks do not pose structural concerns. 

Foundation Crack Size Information

The main problem with the presence of these cracks is their ability to let water into your basement. When it comes to basement wall crack repair there are many different solutions, but only a few make the cut in terms of their effectiveness.

What Does NOT Work

Patching wall cracks on the surface

One of the first things many homeowners assume is that they can patch basement wall cracks by applying plaster over them. However, this does not solve the underlying issue. The soil around your home swells and shrinks as the weather changes, so the plaster will either crack in the middle or lose its bond with the concrete and leak again.

Epoxy

Another “quick fix” for many homeowners is injecting epoxy into the crack. The problem that arises from this method is the fact that epoxy does not allow flexibility for movement. Meaning, when the wall moves, the epoxy won’t, creating even more cracks.

Urethane Liquid

Urethane came about as a better solution to epoxy because it is more flexible. However, urethane does not stretch very far. Therefore, urethane is not an effective basement wall crack repair solution.

What Does Work

Carbon Fiber Wall Reinforcement

What DOES work, is the basement wall crack repair solution called the Carbon Fiber® Wall Reinforcing System.

Stronger than steel, hi-tech carbon fiber reinforcement can provide a permanent repair for cracked & bowed basement walls – innovative product development undertaken by aerospace engineers and the U.S. Dept. of Defense is now being applied to the age-old problem of cracked and bowing foundation walls.

The Carbon Fiber® Wall Reinforcing System utilizes the same technology used to support bridges, skyscrapers and bomb shelters to stabilize building foundations that have sustained damage such as cracks and bowing.

If your basement wall has a lot of cracks, then you might want to consider installing a BasementGutter™ system and wall paneling over your leaking wall cracks without doing anything else to them. By installing a BasementGutter™ and Wall system you are protecting yourself from any future headaches involving floor/wall joint leakage.
