Polyurethane Injection (PU Injection) is a waterproofing method that utilises an expanding polyurethane which gets injected into cracks and voids to stop the flow of water. Polyurethane is a hydroactive compound, meaning it reacts expansively when in contact with water, helping to form a seal and rapidly reducing and eliminating futher water penetration. Variations in polyurethane formulation, allows injected PU to react rapidly and deal with situations where water flow is high, or remain flexible where ongoing movement is anticipated. Polyurethane has also been formulated to enable any water penetration through the finest cracks in concrete structures to be effectively sealed.
