Abstract
The present invention relates to compositions for making sealing walls, dump linings and the like, especially barriers placed in the ground. The compositions contain expandable clay minerals, cement and fillers in aqueous suspension, as well as additives of alkali metal aluminates and alkoxy alkylsilanes. On the basis of these additives, the sealing action against water and pollutants is substantially improved, so that sealing walls prepared therefrom, especially in combination with an also pollutant-resistant sealing floor, can be used for the encapsulation of pollutants in permeable soils.
