Polymer waterproofing membrane (1) is characterized by high tensile strength, good elasticity at low temperature, large elongation, and strong adaptability to tensile deformation of building structural layers under different climatic conditions, which solves the problem that traditional waterproofing materials are easy to crack and ensures waterproof quality. (2) Corrosion resistance, aging resistance and long service life. The service life of synthetic polymer waterproofing membrane is generally over 10 years, for example, the average service life of EPDM waterproofing membrane is over 30 years. (3) adopt cold construction. Due to the requirements of on-site fire prevention and urban environmental sanitation, many cities explicitly prohibit open flame construction and hot asphalt, polymer waterproofing membrane bonding, mechanical fixation, Songpu emergency and other construction methods as cold operation, which not only improves workers' construction conditions and construction site management, but also reduces environmental pollution. (4) It can be single-layer waterproof, and the construction speed is fast. (5) Besides being used for building waterproofing, it is also widely used in water conservancy, civil engineering and other fields. Because some polymer materials have excellent long-term water resistance, when used in underground, water or other humid environments, the basic properties of polymer waterproofing membrane remain unchanged, which can effectively prevent corrosion and mildew. (6) decoration. Adding pigments in the production process of polymer waterproofing membrane can make the membrane obtain various colors.
Polymer waterproofing membrane has high unit price and belongs to high-grade waterproofing membrane. But its comprehensive economic benefits are remarkable. Exposed waterproofing of roof engineering of industrial and civil buildings; Waterproofing of building engineering is vulnerable to vibration and deformation; Rigid protective layer or inverted roof, as well as soil chamber, aqueduct, reservoir, tunnel and other civil engineering construction waterproof.
