Abstract: 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 composit 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.
