Combined sealing structure for enclose waste dumps having steeply - to perpendicular walls and / or - slopes in the form of a dump boundaries

摘要

The present invention relates to a combination seal for landfill sites with perpendicular walls and/or steep slopes as landfill boundaries, consisting of a plastic sealing sheet, concreted to the side facing the landfill of precast concrete slabs anchored in the subsoil with anchor elements, and of a mineral layer located under the precast concrete slabs, the mineral layer consisting of a material which is capable of setting and is free-flowing (= so-called fluid material) and has sealing properties. This material is capable of penetrating into both the space between the wall and/or the slope and the precast concrete slabs, and the gaps between the individual slabs, the material maintaining a pressure bond with the plastic sealing sheet.
