摘要： The present invention is directed to the use of a composite comprising a layer (L1) selected from the group of polyurethane layers, polyisocyanurat layers and polyurea layers as a landfill liner as well as a process for preparing a composite landfill liner comprising a layer (L1) selected from the group of polyurethane layers, polyisocyanurat layers and polyurea layers, the process comprising the step of applying a reaction mixture which is suitable to form a product selected from the group of polyurethane, polyisocyanurat and polyurea products onto a surface. Furthermore, the present invention is directed to a composite comprising a layer (L1) selected from the group of polyurethane layers, polyisocyanurat layers and polyurea layers, a primer layer on one surface of layer (L1), and a protective layer (L2) selected from the group of mortar layers or elastomer layers on the surface of the primer layer. In particular, the present invention is directed to the use of a composite comprising a polyurethane foam layer (L1) as a landfill liner, wherein the layer (L1) comprises a spray product as well as a preparing a composite landfill liner comprising a polyurethane foam layer (L1), the process comprising the step of applying a reaction mixture which is suitable to form a polyurethane foam onto a surface. Finally, the present invention is directed to a composite comprising a polyurethane foam layer (L1), a primer layer on one surface of layer (L1), and a protective layer (L2) selected from the group of mortar layers or elastomer layers on the surface of the primer layer.
