H2O Xpanda PU SuperFlex

H2O Xpanda PU SuperFlex is a hydrophilic polyurethane injection resin designed for sealing damp, seeping and moisture-affected concrete and masonry. When exposed to water, it reacts to form a highly flexible polyurethane seal that expands in a controlled manner and maintains contact within cracks and joints. This is a single-component injection resin with a low expansion profile and high flexibility, making it suitable for long-term sealing where minor structural movement may be present without creating rigid stress points. Typical applications include leaking cracks and joints, basements, retaining walls, tunnels, masonry and other below-ground structures subject to ongoing moisture ingress.
