Roof waterproofing is a common quality problem in building engineering. The main function of roof is to meet the user's needs for water drainage, waterproofing, heat insulation and thermal insulation of the house. Therefore, the roof should not have leakage and water accumulation, and the roof should also be beautified after the completion of the roof. The quality and quality of roof construction are related to the service life of buildings. If the roof leaks or seeps, it will definitely bring inconvenience to people's life, and more or less economic losses will be caused. In serious cases, it will also affect people's normal life.

Filament polyester tire can be widely used in various fields and types of waterproof engineering, and is applicable to various industrial and civil building roof waterproof engineering; Waterproof and moisture-proof of underground works of industrial and civil buildings, and waterproof of structures such as indoor swimming pools and fire pools.

Elastomer (SBS) modified asphalt waterproof coiled material is made of asphalt as the main material, long fiber polyester tire, glass fiber felt or glass fiber reinforced polyester felt as the base, SBS as the modifier, and the surface is covered with polyethylene film, fine sand, mineral particles, aluminum foil and other isolation materials. It can form a high-strength waterproof layer with strong resistance to pressure water.

High tensile strength, good elongation, strong self-healing force, and strong adaptability to shrinkage deformation and cracking of the base; Excellent high and low temperature resistance, large temperature difference resistance, suitable for cold and hot areas, especially for cold areas; Corrosion resistance, mold resistance, low temperature resistance, aging resistance, UV resistance and good weather resistance. No construction is allowed in rainy, snowy and windy days with force five or above. The construction environment and climate should not be lower than 0 ℃.

The distance between the nozzle of the flame heater and the surface of the coiled material should be moderate, and the heating should be uniform within the width. The surface of the coiled material should be melted to bright black, and the coiled material should not be overheated. It is applicable to the waterproof layer of non-exposed roof and underground works, as well as the waterproof layer of subway, tunnel, pool, canal and other works with open cut method. It is especially suitable for projects where open fire is not allowed. It has good flexibility at low temperature and is suitable for cold areas.

Type I coiled material covered with PE film or fine sand is suitable for underground works of general and medium buildings and roofing without rigid protective layer as waterproof layer; Type II: low temperature flexibility * good, Guilin filament polyester tire, suitable for cold areas, buildings and roofs with rigid protective layer as waterproof layer; - The thickness of the waterproof layer on the roof shall not be less than 3mm when the single layer is used, and the thickness of each layer shall not be less than 2mm when two or more layers of protection are provided. When the aluminum foil surface coiled material is used as the waterproof layer on the roof, it can be directly exposed.
