modified bitumen waterproof membrane
Description:
DYAPP Modified Bitumen Waterproof Membrane materials uses polyester reinforcement or fiberglass reinforcement for waterproofing, it's made from polyester felt or fiberglass felt as its reinforcement featuring high strength,elongation and corrision resistance, APP,APAO as its modifier for meeting the torched-on applications, it shall be covered with polyethylene membrane(PE),aluminum foil, colorful sand or mineral granule on its top face and polyethylene membrane(PE)coated on its under face. This series of membrane is designed for the waterproofing of underground construction such as tunnel, subway, basement ,roofs and pools etc.
Advantages:
1.High heat resistance, specially used in high temperature area.
2. Good water resistance, aging resistance, corrosion resistance ability
3.Good flexibility. Can accommodate structural movements.
Features
Good ability of anti-aging, anti-alkali, resistant to high temperature. High tensile strength and elongation, which adapts to the contraction or crack of the base
non-toxicity,odourless,non-pollution and good flexibility
Application:
1, Basement and roofing of key waterproof engineering , general and civil engineering . Such as planting roof, flat roof and sloping roof.
2, Bridge , grain depot, road, granary, tunnel, park ,swimming pool, sewage purifying pool landfill and others.
3, Especially adapting to the area with strong sunshine or high temperature.
