ABSTRACT:
Arrangement for covering the surface, which may be inclined, of loose material, in particular earth or waste dump material, comprising a sealing course which is provided with a top fill. In order to improve the adhesion between the sealing course and the top fill, a rough layer is arranged on the sealing course, on top of the rough layer an adhesive non-woven fabric, which cooperates with the rough layer in an adhesive manner, and on top of the non-woven fabric a retaining mat, which bonds with the top fill. The adhesive non-woven fabric and the retaining mat may be a known geotextile drainage layer which, when reversed, is used for a standard drainage arrangement.
