Disclosed is a heat-sealed polymeric waterproofing membranes having an upper layer and a lower layer penetrating an intermediate carrier material. The upper layer and the lower layer comprise a copolymer. The copolymer is the polymerization product of the monomer ethylene and a comonomer selected from the group, of vinylesters of a C.sub.2 - to C.sub.3 -alkane carboxylic acids and C.sub.1 - to C.sub.4 -alkyl esters of acrylic acid.
These are also described processes for the preparation of the polymeric waterproofing membranes.
The polymeric waterproofing membranes may be used for the sealing of buildings and constructions.
