PU (POLYURETHANE) Injection
PU injection, or polyurethane injection, is a method of repairing concrete structures that have cracks or leaks. Polyurethane injection involves injecting a liquid polyurethane resin into the cracks or voids in the concrete structure. The liquid resin then reacts with the moisture in the surrounding area to expand and solidify, effectively sealing the crack or void. PU injection is a preferred method for repairing concrete structures because it is cost-effective, efficient, and non-disruptive. It can be used to repair a wide range of concrete structures, such as foundations, walls, and slabs.
