South Jersey Waterproofing & Structural Repair is the leader in concrete crack repairs and concrete crack injections.
To stop water from leaking into a concrete basement or concrete foundation crack, liquid urethane foam can be injected into the concrete crack. On contact with water, the liquid urethane foams and expands inside the crack.
South Jersey Waterproofing commonly completes concrete basement crack repairs by injecting urethane into cracks in walls and foundations. To ensure the most coverage and correction, we apply these injections from the bottom to the top and the entire width of the foundation wall. As a result, the water stays outside the foundation, and the basement contents are safe. The foam created is a closed-cell structure that will not allow water to work through the basement crack. The finished foam bonds tightly to the surrounding concrete to ensure that water does not push the foam out of the foundation crack. Once the urethane has foamed and expanded inside the foundation crack, water cannot leak into the basement again.
In comparison, a patch repair using hydraulic cement is much less reliable. Hydraulic cement must have the crack chiseled out into a vee-notch, which can be a long and messy process. The chiseled-out notch is only a few inches deep; thus, the hydraulic cement cannot inject into the entire width of the concrete wall. Therefore, water still gets into the basement crack from the outside. In addition, salts break the bond between the hydraulic cement and the existing concrete foundation over time, allowing water to leak again into the basement.
A patch repair covers the inside surface of a foundation crack. This is a weakly bonded repair that the water can push off of the wall and allow water to leak into the basement.
Repair from the inside means no digging or messy excavation
Concrete basement and foundation crack repair is done from the inside of the basement. The home’s outside landscaping does not have to be removed and the foundation excavated for the leak repair. Also, there is no drilling or chiseling to perform a foundation crack leak repair. The concrete basement crack is filled entirely by the concrete crack injection repair material. This stops water from leaking into a basement and keeps the possessions dry.
