Polyester Reinforced SBS Waterproofing Membrane High Tensile Building Waterproof Material

Polyester Reinforced Sbs Waterproof Membrane High Tensile Building Waterproof Material

Product Advantages

Excellent high-low temperature resistance: Maintains good flexibility at -25℃, resists flowing at high temperatures, and adapts well to all-season environments.

High tensile strength and large elongation: The membrane deforms together with minor cracking and displacement of the substrate, delivering strong crack-resistance performance.

Great aging and corrosion resistance: Resists UV radiation, rain erosion, acid and alkali. Suitable for both underground and exposed applications with long service life.

Firm bonding and reliable waterproof sealing: Tightly bonded to the substrate after hot-melt construction. Overlaps fuse into an integral structure to reduce water-channeling risks.

Strong compatibility: Compatible with various substrates and available for composite waterproofing systems to fit diverse project scenarios.

Complete specifications: Available in multiple thicknesses with top surfaces of shale, PE film or aluminum foil, meeting requirements for exposed and non-exposed conditions.

technical parameters

Material Features

Type I: Heat resistance 90℃, low-temperature flexibility -20℃. 

Type II: Heat resistance 105℃, low-temperature flexibility -25℃, preferred for cold-climate regions.

Top-surface separators: PE polyethylene film, M mineral shale granules

Flexibility: Maintains elasticity at low temperatures, adapts to substrate settlement and cracking deformation.

Bonding performance: Asphalt features strong self-adhesion after hot-melting; overlapping seams can fuse into an integral body.

Chemical resistance: Resistant to acid, alkali and corrosion, performs stably in underground humid environments.

Weather resistance: Membrane with shale granule surface resists UV rays and is applicable for open-air roofs. PE-film version shall not be directly exposed.

Construction properties: Mainly installed by hot-melt method. Cold-adhesive construction is also available, as well as composite membrane-coating system with non-curing bitumen coating.

Application Scope

1. Roofs and sloped roofs of various industrial and civil buildings; mineral‑granule surface for exposed roof waterproofing

2. Waterproofing for basement slabs, side walls and top slabs

3. Waterproofing for underground garages and civil air‑defense projects

4. Waterproofing and anti‑seepage for subways, tunnels and culverts

5. Anti‑seepage treatment for reservoirs and sewage treatment tanks

6. Old roof refurbishment and waterproofing retrofitting of existing buildings

7. Waterproofing works for bridges and parking lots

8. Green roofs (auxiliary root‑resistant layer is required)
