Abstract
Abstract Subsoil impermeablisation. Infiltrating flow from a reservoir into excessively permeable subsoil is used to induce penetration of finely divided elements to reduce the degree of permeability. Spec. the finely divided elements may be mixed with the surface layers of the bottom of the reservoir and penetrate the subsoil under the action of water filling the basin and infiltrating the subsoil. The finely divided material may include a substance which swells.
