YSBP Black Gold Shield Poly Roof Roll is a pre-applied self-adhesive waterproof roll designed for pre-lay, anti-adhesive construction. It is made with a polyester base fabric as reinforcement, coated with modified asphalt on both sides. The bottom surface is covered with polyethylene film or fine sand as a release layer, while the top surface is coated with silicone release film or paper.
Product Features
- High tensile strength and elongation due to polyester base, with strong tear, puncture, and rupture resistance. Adaptable to substrate shrinkage and cracking.
- Excellent adhesion, with seams self-bonding to match the roll’s service life; safe and environmentally friendly. Full adhesion to the building structure effectively blocks liquid water and vapor penetration.
- After pre-applied roll installation, reinforcement and concrete can be laid directly without additional protection layers, accelerating construction progress.
Scope of Application
- Widely used for basements, bottom slabs, and side walls in underground projects such as excavated subways.
Product Specification Type
- Thickness: 4.0 mm
- Width: 1.0 m
- Area per roll: 10 m²
Executive Standards
- GB/T 23457-2017 《Pre-applied Waterproof Rolls》
Construction Method
- Pre-lay rolls starting with horizontal surfaces first, then vertical surfaces.
- Use a heavy roller on overlaps to ensure full adhesion.
- For low-temperature installation, use a hot air welding gun to assist adhesion.
- During vertical installation, mechanically fix edges every 400–600 mm within 10–20 mm of the edge.
- At transitions from horizontal to vertical surfaces contacting permanent protection walls, use loose-lay method.
- When no protection wall is installed, apply reliable protection measures at horizontal-to-vertical transitions.
Transportation and Storage
- Store different types and specifications separately; do not mix.
- Avoid sunlight and rain, ensure ventilation.
- Maximum storage temperature: 45℃. Flat storage: ≤5 layers; vertical storage: single layer.
- During transport, prevent tilting or lateral pressure; cover with tarpaulin if necessary.
- Shelf life: 1 year under normal storage and transport conditions.
