Abstract
A basemented floor structure under a waste dump, whereby the burden of the waste body is transferred to piers and then onto foundations and the subgrade, and on which layers of sealing material, drainage material or protective material lie, is built up from individual support elements separated from one another by seams and having an upwardly convex or concave shape. By this structure, unequal setting of the subgrade can be accommodated without harm and cracks in the floor structure are prevented. The upper surfaces of the support element are inclined toward the piers. The seepage is taken from collecting zones through a water removal system to a purification plant.
