ABSTRACT:
Liquid or water-soluble pollutants which have entered into permeable soil strata are prevented from spreading and contaminating ground water by surrounding the contaminated zone on all sides with vertical barriers and closed off at the bottom by a horizontal injected floor which seals not only against water but also against the pollutants. The pollutant resistance of the floor is achieved by the use of injection materials on a silicate basis containing trialkoxysilanes of the general formula R-Si(OR').sub.3.
