production of waterproofing materials. SUBSTANCE: material has two layers manufactured from polymer including ethylene links, and at least one comonomer selected from group containing vinyl esters of alkancarboxylic acid with 2-3 carbon atoms and C1-C4 acrylic acid esters, standard additives and polyolefin or mixture of polyolefins. Reinforcement layer sandwiched between two mentioned layers is made from fabric, loosely laid particles, knitted fabric, canvas or like material. Waterproofing material has high tensile strength and sufficient tensile elongation at normal and increased temperature. EFFECT: increased efficiency and simplified structure. 3 cl, 3 tbl, 2 ex |
