ABSTRACT OF THE DISCLOSURE: The present invention relates to compounds for producing sealing-walls, dump-linings and the like, more particularly to sealing-means built in the ground. They contain clay minerals capable of swelling, cement and fillers in aqueous suspension, as well as the additives alkaline- metal aluminates and alkoxyalkyl-silanes according to the invention. These additives substantially improve the sealing-action against water and pollutants, so that sealing- walls produced therefrom, especially in conjunction with a similarly pollutant-resistant floor, may be used to encapsulate pollutants in permeable ground.
