Polyurethane is a fluid resin which is injected into concrete cracks, rock fissures, expansion joints and other voids in solid underground structures. When used in concrete crack injection applications the polyurethane is injected into a crack; within minutes the polyurethane undergoes a chemical transformation from a liquid to a solid. The versatility, and consequently the popularity, of polyurethane resins in crack injection applications stems from polyurethane’s properties:
