What Makes Our SBS Waterproof Membrane Different?
SBS-Modified Elasticity
The SBS-modified system provides high elasticity for waterproofing applications, with elongation at break ≥250% on polyester-reinforced types.
It helps the membrane adapt to structural movement and temperature changes without cracking.
Strong Waterproof Barrier
The modified bitumen layer forms a continuous waterproofing barrier with impermeability rated at 0.3 MPa for 30 minutes with no leakage.
It is suitable for areas where reliable water protection is required, including below-grade foundations and flat roofs with standing water risk.
Good Low-Temperature Flexibility
SBS technology provides low-temperature flexibility down to -25°C (Type II) or -20°C (Type I) with no cracking.
Actual cold-weather installation should follow project requirements and manufacturer guidance.
Multiple Surface & Application Options
Surface options include PE film, sand, mineral flakes, and aluminum foil, each suited for different exposure conditions: PE film for non-exposed layers, sand for below-grade applications, mineral flakes for UV-exposed roofing, and aluminum foil for reflective surfaces.

Waterproofing Applications for Various Projects
Roof Waterproofing
Suitable for residential and commercial roof waterproofing projects, including flat roofs, pitched roofs, and exposed single-ply roofing systems.
Mineral-flaked surface type is recommended for UV-exposed roofing, providing weather resistance without requiring a separate protective layer.
Basement & Foundation Waterproofing
Used for basement walls, foundations, and other below-grade areas where continuous waterproof protection is required.
Provides a waterproof layer between the structure and surrounding moisture. Torch-applied method creates a strong bond to the substrate for reliable below-grade performance.
Underground & Infrastructure Projects
Can be applied to underground structures and related infrastructure including tunnels, Metro stations, and water-retaining structures.
PE film or sand-surfaced types are typically selected for non-exposed, buried applications where the membrane is covered by protective layers.
Balcony & Other Building Areas
Can be used for balconies, terraces, and selected building areas requiring surface waterproofing.
The final membrane type should match the substrate, exposure conditions, and construction method.
Common Questions Answered
1. What is the difference between self-adhesive and torch-applied SBS membrane?
Self-adhesive membrane has a peel-and-stick backing for installation without an open flame. Torch-applied membrane needs a torch for bonding. It can create strong adhesion on well-prepared surfaces.
2. What thickness should I choose for my project?
Thickness selection depends on project usage, structural conditions, and local construction standards. The final specification should be confirmed by the project engineering team.
3. What is the typical shelf life of SBS membrane?
The typical shelf life is 12–18 months when stored in the original packaging in a cool, dry, and shaded area. Please confirm the shelf life and storage conditions when ordering.
4. What is the MOQ for SBS waterproof membrane?
MOQ is quoted based on factors such as thickness, surface finish, and total order volume. Contact Jinsimai with your specifications for a confirmed MOQ.
