Tunneling foam

Water ingress into tunnels, even the smallest leak, can have disastrous effects and compromise the durability of the structure. Among various choices, polyurethane foam is the best solution for addressing this issue due to its mechanical properties and effective sealing capabilities. As a result, demand for this product is increasing.

This product is injected as a liquid into cavities and cracks, where it then expands and forms foam. It has a low viscosity, allowing it to fill and repair voids and cracks in foundations, substructures, and supporting structures. Additionally, it has excellent adhesion and, after curing, demonstrates strong water resistance (hydrophobic properties).
