ABSTRACT:
A soil injection agent on an alkali metal silicate basis, containing as gelling agent trialkoxysilanes of the formula R-Si(OR').sub.3, in which R is an aliphatic moiety of 1 to 6 carbon atoms and R' represents equal or different alkyl moieties of 1 to 4 carbon atoms, is adjusted for properties by the addition of acid alkali metal phosphates or ammonium phosphates and/or phosphoric acid. The addition improves the sealing and strengthening action of the gels and permits a reduction of the silane content, without impairing the resistance of the gels to pollutants.
