Project Description
Torch-On Bituminous Waterproofing
The Builden BT series of torch-on bituminous waterproofing membranes is manufactured from a rich mixture of bitumen and selected APP (Atactic Poly Propylene) polymers blended together to obtain excellent heat & UV resistance and waterproofing properties. It has superior tear-resistant qualities as the polymerised bitumen is coated onto a dimensionally stable reinforcement core of non-woven spun-bond polyester rot-proof fabric giving it a long lifespan.
Builden BT series products exhibit:-
- Excellent resistance to positive water & vapor pressure
- Good heat resistance
- Good dimensional stability under tension
- Can accommodate structural movements due to its excellent flexural qualities
- High puncture and fatigue resistance
- High tensile and tear strengths
- Resistant to water borne chemicals and chlorine free
