Roof Waterproofing
Flat roofs: Suitable for concrete roofs, steel structure roofs, etc., especially in areas that need to withstand temperature changes (such as high temperatures in summer and severe cold in winter). The high elasticity of SBS membranes can cope with the deformation of the roof base caused by thermal expansion and contraction, reducing the risk of cracking.
Sloped roofs: With a suitable adhesive, it can be used for sloped roofs with a slope not exceeding 25%, such as the sloped roofs of villas and factories, which can effectively prevent rainwater penetration.
Green roofs: In the waterproof layer of green roofs, SBS membranes can serve as the core waterproof layer. It is necessary to choose root-resistant types (with root-resistant layers such as copper base) to resist damage from plant roots.
II. Underground Engineering Waterproofing
Basement floor and side walls: Basements are in a humid or water-containing environment for a long time. The water resistance and impermeability of SBS membranes can effectively block the penetration of groundwater, especially suitable for scenarios with deep burial depth and high water pressure.
Underground garages: Including the roof, floor, and walls of the garage, it can cope with the base deformation caused by vehicle loads and ground settlement, ensuring the garage remains dry.
Tunnels and pipe corridors: In underground structures such as subway tunnels and comprehensive pipe corridors, SBS membranes can be an important part of the waterproof layer, adapting to structural settlement and vibration.
III. Wall and Special Part Waterproofing
External wall waterproofing: Used on the outside of the external wall leveling layer, it can prevent rainwater from seeping into the wall, especially suitable for building external walls in rainy or humid areas.
Kitchen and bathroom waterproofing: Although waterproof coatings are more commonly used in kitchens and bathrooms, SBS membranes can be used when the base is flat and rapid construction is required (attention should be paid to the adhesion treatment with decorative layers such as ceramic tiles).
Junction points such as internal and external corners, pipe roots: As a waterproof reinforcement layer, it is paved at easily leaking parts such as internal and external corners, pipe roots of roofs and basements to enhance local waterproof effects.
IV. Other Scenarios
Bridge and road engineering: Used for waterproofing of bridge decks and road bases, preventing rainwater from seeping into the internal structure of bridges, and delaying steel corrosion and concrete aging.
Water pools and water conservancy projects: Suitable for waterproofing of structures such as water storage pools and sewage treatment pools, resisting long-term immersion in water.
Notes
SBS waterproofing membranes are divided into hot-melt type (need to be pasted by heating with a blowtorch) and self-adhesive type (can be pasted directly without heating). The choice should be based on the construction environment (such as whether open flames are allowed) and base conditions.
In cold regions, priority should be given to models with good low-temperature flexibility (such as -20℃, -25℃ grades). In high-temperature regions, attention should be paid to their heat resistance (usually required to be ≥90℃).
During construction, the base must be flat and dry, and the overlap width of the membranes should meet the specifications (usually 10-15cm) to ensure the waterproof effect.
