ABSTRACT:
Dome for waste dumps with at least one outside filter layer and one draining and/or degassing area arranged within the outside filter layer, characterized in that the draining and/or degassing area is formed by at least one shaped body of plastic material, having a hollow space volume of at least 70% and that a continuous supporting tube is placed in the shaped body having a length corresponding to the height of the dome. These shaped bodies may consist of three-dimensionally shaped panels of plastic material or of a multitude of intersecting filaments of melt-spun polymers arranged in loops and having a filament diameter of at least 0.1 mm, and which are bonded to each other at their points of intersection. In a preferred embodiment of the invention, the supporting tube is coupled to a base plate. The shaped body may consist of a rolled-up mat, on which the filter layer is covered.
