Abstract

The invention relates to pollutant-resistant compositions containing organopolysiloxanes. They are used for producing impermeable walls and similar ground seals introduced into the earth. This pollutant-resistant organopolysiloxane-containing composition comprises (A) a salt of organic or inorganic acid and organopolysiloxane which has SiC-attached radicals containing basic nitrogen in amounts of at least 0.5% by weight of basic nitrogen, based on the weight of this organopolysiloxane, (B) organosilicon compound containing basic nitrogen in amounts of from 0 to 0.5% by weight, based on the weight of this organosilicon compound, (C) swellable clay minerals and (D) hydraulic binder.
