摘要： A filling up process is disclosed for water-proofing engineering objects buried in the ground. In a first embodiment, an aqueous solution of non-polluting, water-soluble polyvalent metals salts is led onto or into the engineering object and if required any excess of aqueous metal salt solution is removed. In a second embodiment, a possibly additive-containing, aqueous sodium water glass solution or aqueous silicic acid sol with a pH value from 1 to 9 is supplied to the engineering object. The process has the following characteristics: (a) the viscosity of the aqueous solution of polyvalent metal salts is set from 10 to 1,000 mPa.s, preferably from 20 to 200 mPa.s, by admixture of water-soluble, non-ionic linear polymers; (b) as solution of water-soluble polyvalent metal salts a solution of said salts saturated at 35-45 DEG C is used; (c) an amount of alkali carbonate and/or alkali hydrogenated carbonate and/or if required carbon dioxide that does not cause any sedimentation is added to the solution of water-soluble polyvalent metal salts; (d) a previously prepared, fine aqueous suspension is added to the solution of water-soluble polyvalent metal salts and/or a fine suspension is generated in the solution itself; or (e) methods (a) to (d) may be combined. When methods (a) and (d) are used, the order of the two solutions (first solution, second solution) may also be reversed. If required, this filling up process is repeated one or several times.
