H2O Xpanda PU Seal Hydrophilic Injection

H2O Xpanda PU Seal is a hydrophilic polyurethane injection resin designed for sealing damp, seeping, and moisture-affected concrete and masonry. It reacts with water to form a highly flexible polyurethane seal that expands in a controlled manner, maintaining contact within cracks and joints.

This is a single-component injection system that reacts only when exposed to moisture. Its low expansion profile and high flexibility make it suitable for long-term sealing where minor movement is present without creating rigid stress points.

Commonly used for basements, retaining walls, tunnels, and below-ground structures experiencing ongoing moisture ingress where controlled swelling and flexibility are required.
