Abstract: A process for restoring the damaged bottom of a storage tank. The process is initiated by preparing a slurry containing unconsolidated solids and a gelation solution. The gelation solution includes an aqueous liquid solvent, a crosslinkable polymer, and a crosslinking agent. The slurry is placed on the internal bottom surface of the storage tank in a sufficient volume to fully cover the surface. The gelation solution is then gelled substantially to completion in the storage tank to form a gel that binds the unconsolidated solids and converts the slurry into a hardened conglomeration. The hardened conglomeration provides a coat over the internal bottom surface of the storage tank to prevent further damage to the bottom of the tank and leakage therethrough.
