Polyurethane Foam

Polyurethane foam is utilized as part of the OBIC multi-layer liner system. This spray applied material provides a build-back surface to the wastewater structure. As it expands on the surface it fills cracks, bug holes, missing mortar joints or eroded areas. The higher density of the OBIC polyurethane foam enhances the strength of the liner system affording superior resistance to hydrostatic groundwater infiltration.
