SBS Modified Asphalt waterproof Membrane with Aluminum film
Description:
SBS 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 corrosion resistance, SBS compound 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
Good ability of anti-aging, anti-alkali, resistant to low temperature. High tensile strength and enlongation, which adapts to the contraction or crack of the base.
Application
1.Basement and roofing of key waterproof engineering, general and civil engineering.
2.Bridge, road, granary, tunnel, park, swimming pool, sewage purifying pool and others.
3.Especially adapting to the waterproof of structure changeable and cold area.
