Description

ABSTRACT Liquid or water soluble noxious substances which have extended into water permeable ground layers are prevented from spreading and contaminating ground water, as a result of the harmed region being enclosed on all sides by vertical seals and being closed off below by a horizontal injection base, which seals not only against water but also against the noxious substances present. The resistance of the base to noxious substances is obtained by use of injection means based on silicates which contain trialkoxysilanes of the general formula R-Si(OR')3.
