H2O Xpanda PU SemiFlex is a hydrophobic polyurethane injection resin designed for stopping active water leaks in concrete and masonry. It reacts with moisture to form a semi-flexible polyurethane foam capable of withstanding hydrostatic pressure. Used with H2O Xpanda PU SemiFlex Catalyst, the reaction time can be adjusted to suit site conditions, water flow and leak severity. Its low viscosity assists penetration into fine cracks when injected under pressure. Typical applications include active crack injection, basement and retaining wall leaks, water cut-off barriers, saturated ground and other below-ground water ingress applications. IMPORTANT: H2O Xpanda PU SemiFlex Resin must be used with the nominated PU SemiFlex Catalyst at the required dosage. Reaction time is controlled by varying the catalyst ratio.
