Before roofing main waterproof layer polypropylene construction, should focus on drainage and structure complex detail node processing and additional sealing layer paste. The corner shop should add an additional layer; yin and yang angle, etc. are made of R = 20mm rounded. Experiments show that: Compared with ordinary mortar / concrete, such as adding 0.1% volume fraction (about 0.9Kg / m3) of monofilament, crack resistance mortar / concrete is increased by 70%. 2, greatly improving the impermeability of concrete. Polypropylene monofilament fiber bundle concrete 0.9Kg / m3 content than ordinary concrete impermeability capacity increased by 60% to 70%. 3, significantly improve the impact resistance and abrasion resistance of concrete waterproof polypropylene, polypropylene, Shouguang Tianxiang water provided by Shouguang City Tianxiang waterproof material plant.
