Basements made of concrete can have cracks design in them. These cracks can let water seep into the interior of the basement and damage a homeowner's possessions. Stopping the water leak is an easy process that can be fulfilled, from the interior of a basement without digging up the exterior.

Traditional heal Process

In the past a heal was done by a technician chiseling a vee-notch 6" wide and 4" deep into an 8" wall. This chiseling can sell out the structural drive of the wall in that area. Once the notch was completed, a product called hydraulic cement was packed into the vee-notch. The hydraulic cement then cures and stops water.

The disadvantage of using hydraulic cement is that water still gets into the crack. It then dries out and leaves behind the salts that were dissolved in the water. Over time these salts break the bond in the middle of the wall and the hydraulic cement. Also, high hydrostatic pressure can cause the hydraulic cement to crack and break. The labor involved to chisel out the notch can make the heal relatively expensive.

Polyurethane Foam Injection

The modern way to heal a basement crack leak in a concrete wall is to inject a polyurethane foam into it. This foam is verily injected by a technician in a liquid form. The foams are commonly two components and mix themselves before going into the crack.

The liquid urethane enters the crack and begins to foam and expand. This foaming performance drives out water, forms a tight seal with the concrete and stops water from entering the basement. When the injection is complete, the basement wall crack will be filled from the bottom to top and from the front to back. Now water will be unable to seep into the crack. Salts will not be deposited in the crack and cause the bond in the middle of the foam and concrete to be broken.

The heal process is quick, clean and much less high-priced than a heal using hydraulic cement. No chiseling is required or digging up the surface of the foundation.
