Learn more about grout injection.
Injection grouting is the process of filling cracks, opening joints, or voids or honeycombs, of masonry or concrete members. The grouting material is cured under pressure, and may be utilized to help strengthen structures or stop water from getting into. Grouting can either enhance or slow the water flow through the structure. Also, it is utilized to repair flaws in constructions made of concrete or masonry. The flowable material grout is composed of plastic, and must not shrink to completely make up the gap voids. Also, it must be stable and free from cracking, delamination or crumbling. There are different types of grouts such as cement grout, polymer-cement slurry, epoxy, urethane, and high-molecular-weight methacrylate (HMWM).
The process of high pressure polyurethane (PU) injecting grout is the injection of polyurethane onto the substrate at high pressure so the cracks and voids in the substrate will be filled with the waterproofing slurry to stop any potential leakage of water. uu1e9wixzk.
