Abstract: The present invention provides processes for infrastructure repairs and geo-stabilization with a low-exotherm polyurethane foam, grout or elastomer. The inventive process involves at least partially filling a cavity in the infrastructure or earth with a low-exotherm polyurethane foam, grout or elastomer made from at least one polyisocyanate, at least one isocyanate-reactive compound and an organic particulate material capable of absorbing heat, optionally in the presence of one or more chosen from water, surfactants, pigments, catalysts, alkali silicates and fillers and curing the polyurethane foam, grout or elastomer. The inventive processes may improve the repair of buildings, foundations, roads, bridges, highways, sidewalks, tunnels, manholes, sewers, sewage treatment systems, water treatment systems, reservoirs, canals, irrigation ditches, etc.; and in the geo-stabilization of mines, caves, wells, bore-holes, ditches, trenches, pits, cracks, fissures, craters, postholes, potholes, sinkholes, wallows, waterholes and the like. The inventive solid polyurethane compositions are made from at least one polyisocyanate, at least one isocyanate-reactive compound, and an organic particulate material capable of absorbing heat, optionally one or more chosen from water, surfactants, pigments, catalysts and fillers. Such solid polyurethane compositions may improve reaction injection molding (RIM), spray elastomer and cast molding processes.

Abstract: The present invention provides water swellable one-component sealants prepared by incorporation of polyols containing ethylene oxide ("EO") into the backbone of the polymer. The inventive one-component hydrophilic polyurethane sealant contains a silane-terminated polyurethane prepolymer, a compound having an ethylene oxide content of at least about 40 wt.%, based on the weight of the compound and a catalyst, optionally, one or more of plasticizers, fillers, pigments, drying agents, light stabilizers, antioxidants, thixotropic agents and bonding agents. The one-component hydrophilic polyurethane sealant increases at least about 1.4% by weight and at least about 2.5% by volume upon exposure to water for 24 hours and are capable of curing in a high humidity environment (including underwater) without foaming and maintain physical characteristics such as hardness.
