Abstract

Methods are disclosed for treating porous media such as subsurface storage tanks or excavations therefore to form primary or secondary permeability barriers. A treatment fluid comprising a polymerizable monomer, a diluent therefor, and a strong acid catalyst mixed with steam is injected into a volume to be treated and contacted with the interior surface thereof. Contact is maintained for a duration sufficient to cause polymerization to occur forming an impermeable barrier in or on the interior surface of the treated volume.
