SBS modified bitumen waterproofing construction material
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:
1. Low temperature resistant,can used in all season in the year.
2. Good stab-proof , Tear resistance ability.
3.High tensile strength and elongation, which adapts to the contraction or crack of the base.
4. Good water resistance, aging resistance, corrosion resistance ability
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.
