Abstract: A composition and method for stabilizing or consolidating soil, rock, coal, mineral, or other loose aggregates, especially in a subterranean environment. A hydroswelling admixture of polyurethane prepolymers and hydrophobic plasticizer is injected or pumped into the interstices of loose aggregates. The admixture is a single component system and has a low viscosity. The admixture reacts with water that is naturally present in the subterranean environment or with water that is simultaneously pumped in prior to or concurrent with the admixture. Upon reaction, the product polymerizes and swells to a polyurethane foam, in order to stabilize the loose aggregates.
