Our polyurethane injection solutions are tailored to address a wide range of concrete and water ingress issues, with two specialized formulations for different conditions.
Water-based Polyurethane (WPU) is designed for slow, deep penetration, allowing it to seal fine capillaries and bond structurally with concrete. This makes it ideal for treating rising damp in walls, hairline cracks in slabs and roofs, damp retaining walls, cold joints without active leaks, and microcracks caused by shrinkage or thermal movement.
Oil-based Polyurethane (OPU) delivers rapid, high-volume expansion, reacting instantly with active water to stop high-flow leaks and infiltration. Engineered for demanding situations, it effectively seals leaking pool joints, cold joints with active seepage, tunnel seepage, pipe penetration leaks, and retaining walls under water pressure. The resulting flexible waterproof barrier can withstand dynamic water movement and high pressure, providing immediate and lasting protection.
Together, WPU and OPU provide a complete, high-performance solution for both passive moisture issues and aggressive water ingress challenges.
