tuowang Color Wide polyvinyl chloride (pvc) waterproofing membrane is a high performance polymer waterproofing materials, in PVC resin as the main raw materials, the incorporation of special agents and anti-aging components. using advanced equipment, and advanced technology into production. Products have the tensile strength, elongation, the rate of contraction of small, low-temperature flexibility, and long service life characteristics. 1.05m,2.05,2.10m products width, thickness 0.8,1.0,1.2,1.5. 2.0mm (special specifications can be customized), the product is stable, reliable, and convenient.

Product Performance :
1、Long service life, resistance to aging and roofing material to be used in 20 years, the underground up to 50 years.
2、Strong high tensile strength, elongation, heat treatment changes the small size
3、Flexible hypothermia that meet environmental temperature change is good.
4、Root penetration resistance, and will create green roofs.
5、Anti-perforation good.
6、Construction of convenience, welding, solid reliable environmental pollution-free.
7、Strong chemical resistance, apply special occasions.
8、Good plasticity, corner detail treatment convenient and quick.
9、Easy maintenance and low cost.

Construction Technology :

一、Roof Engineering(GB50207-2002)

1．Construction of grassroots strength, thickness, Water rates, and other indicators should be consistent with national norms design requirements before proceeding with PVC waterproof membrane construction.　　
2．Identify planning membrane Underground direction and order, waterproof layer on the natural contours of the arrangement at the grassroots level. Formation straight, not bent, in accordance with the requirements of the lap lap width, size precision.
3．According to a fixed method of choice for the fixed, such as : mechanical fixation, full bonding method of bonding, fixed point, it should be tightly sealed
4．Waterproofing membrane surface welding lap site should wipe clean, dry lap width of not less than 60mm, using hot air welding, welding and welding welding mouth direction was 45 ° angle, and welding Roller mouth equality and maintain a distance of about 5mm. Welding side was due Luminance melts exudative, no leakage of welding, welding jump, charred or welding is not strong, Welding may not harm non-welded parts of the membrane.
5．Coil received the first Department of metal pressure fixed, the largest nail distance should not exceed 900mm with sealant sealed cement mortar is closed.　
6．The whole project site waterproof construction has been completed, a comprehensive quality inspection with them.

二、Underground Engineering(0B50208-2002)
1．Underground construction methods can be divided into defense posted outside defense and foreign law within two stickers, According to GB50208 standard specifications with different thickness of the PVC membrane and different construction side Law, and adhere to the following general provisions :
2．Construction of grassroots strength, thickness, Water rates and other indicators should be consistent with national norms design requirements before proceeding with PVC waterproof membrane construction.　
3．According to different parts of the waterproof reasonable choice method, the concrete implementation of GB50208 standard.　
4．Coil lap width should be not less than 100mm. the upper and lower levels of membrane seams should be staggered one-third of sheet width and the upper and lower levels of membrane not perpendicular to each other Stones.　
5．Coil lap width should be not less than 100mm. the upper and lower levels of membrane seams should be staggered one-third of the width roll joints to take over the use of welding, of the single-lap weld width is not less than 10mm.
6．PVC membrane laying ride should not have to sag, tension and breakage. The inspection can only be confirmed after a process under construction.

三、Tunnel project and special occasions use of the light of the implementation of national construction norms or linked construction company providing guidance.
