How to do the crack injection?

Cracks in poured foundations can be repaired by low-pressure injection of an epoxy or polyurethane foam material. For the repair of cracks in concrete floors, there are certain epoxy and polyurea materials, suitable for such tile repairs. The technician's job is to regulate the flow, as well as the pressure of the liquid in the concrete crack for a lasting end result. If water seeps continuously through the crack, the flow must be stopped for the epoxy injection to produce a proper repair.

By injecting Roadware 10 Minute Concrete Mender into concrete, the rapid gel and cure time allows you to perform a complete repair from the bottom of the crack to the top. This material can be combined with fabricated sand to form a PCC-compatible polymer concrete that can structurally repair cracks and chips in concrete. Most homeowners better identify concrete cracks in their basement, either in the foundation wall or in the floor. Let the compression spring of the dispensing tool push the material into the crack with slow, steady pressure.

Epoxy injection that takes several hours to cure will sink to the bottom of the crack and build up in the base before it has a chance to cure. However, the pillars will not seal existing cracks, which may still need to be injected to prevent leakage after the base has stabilized. Epoxy resins that are labeled as water insensitive during curing can develop milky white bond lines if injected into wet or damp cracks. Because epoxy and polyurethane foams used for crack injection are two-component materials, it is critical to mix them in the correct proportions to avoid problems with unreacted polymers.

Although injection of epoxy resin presents an excellent means of repairing cracks in floors and walls, it is not designed to seal leaks. Concrete Mender does not need to be forced into cracks with high-pressure pumps and extraordinary methods. Crack injection can be successfully performed in cracks as narrow as 0.013 mm wide with general epoxy injection resins. The general consensus is to seal the crack with a sacrificial epoxy and install injection ports every few centimeters.
