摘要

A process for solidifying and making watertight underground and other building structures, artefacts (especially conduits, pipes and canals), rocks and soil, utilising an aqueous water glass solution and fluosilicic acid. In, on or in the vicinity of the object to be treated water glass solution is brought into contact with fluosilicic acid in the presence of 0.01-1 part by weight %, expediently 0.05-0.2 part by weight, of a hydrogel-forming water-soluble organic polymer and a cross-linking agent for the polymer, calculated on one part by weight of solid material in the water glass solution. The thus formed gels are resilient as well as suitably solid and strong and provide very good water-tightness.
