Injectable PU foam is a low-viscosity liquid material injected under pressure into cracks, joints, and voids. Upon contact with water, it reacts and expands to form a flexible or rigid foam that blocks water paths and prevents further leakage.
Injectable Polyurethane (PU) Foam is a highly effective waterproofing solution used to stop active water leaks and seal cracks in concrete structures. It expands on injection, filling voids and cracks to create a durable, watertight seal.
Applications of Injectable PU Foam
Crack sealing in concrete structures
Basement and foundation leak repair
Water leakage control in tunnels
Expansion joints and construction joints
Retaining walls and underground structures
Industrial and commercial buildings
Key Benefits of Injectable PU Foam
Stops active water leaks instantly
Expands to fill cracks and voids completely
Excellent adhesion to concrete and masonry
Flexible and durable performance
Long-lasting waterproof sealing
Minimal surface disruption



Injectable PU foam is ideal for repair and rehabilitation projects where traditional waterproofing methods are not feasible. It provides targeted, efficient, and permanent leak-sealing solutions without major demolition.
