What is SBS bitumen membrane?
SBS bitumen membrane is a type of roofing or waterproofing material that is commonly used in the construction industry. SBS bitumen membrane is made up of a base layer of modified bitumen that is reinforced with a polyester or fiberglass mat, and then coated with a layer of SBS rubber on the top and bottom. This provides the membrane with excellent flexibility, durability, and resistance to temperature changes.
SBS bitumen membrane is used as a roofing material on flat or low-slope roofs, as well as in below-grade waterproofing applications such as basements and foundation walls. It is also used as a flashing material around roof penetrations, such as vents and chimneys.
One of the benefits of SBS bitumen membrane is its ability to adapt to different weather conditions and temperature changes. It can also withstand heavy foot traffic and exposure to UV radiation without deteriorating or cracking. SBS bitumen membrane is also resistant to water, making it an ideal material for waterproofing applications.
Benefit of SBS bitumen membrane roofing
Flexibility: SBS bitumen membrane is highly flexible and can easily conform to the shape of the roof or surface it is applied to. This makes it an ideal material for use on roofs with complex shapes or structures.
Durability: SBS bitumen membrane is extremely durable and can withstand harsh weather conditions, including extreme heat and cold. It is also resistant to UV radiation and can last for many years without deteriorating.
Waterproofing: SBS bitumen membrane is an effective waterproofing material and can prevent water from penetrating the roof or surface it is applied to. This helps to protect the underlying structure from water damage and prolong its lifespan.
Energy efficiency: SBS bitumen membrane is available in different colors and finishes, including reflective options that can help to reduce energy consumption by reflecting heat away from the building.
Ease of maintenance: SBS bitumen membrane is relatively easy to maintain and can be repaired or patched in the event of damage or wear and tear.

Bitumen membrane usage
SBS Bitumen membranes are generally used in single or multi-layer waterproofing systems. They may be used on accessible or inaccessible concrete roofs, balconies, wet areas, foundations & footings, below grade structures, swimming pools, tunnels or any smooth concrete surface that require flexible waterproofing. Bitumen membrane is generally used for covered applications only.
Application of SBS membrane
The surface to be waterproofed should be clean, dry, firm, even and free of any surface imperfection.
A coat of primer solvent based should be applied on the prepared surface and allowed to dry. The membranes are bonded to the surface by directly torching it using propane/butane gas. The laying should start from the lowest point of the roof and overlapping should be formed so as to shed water. Excessive heating may damage the reinforcement. The overlaps of adjacent rolls should be staggered.
The side laps should be min. 5cm and end laps min.10cm. Details such as corners, edges and joints should be carefully prepared in advance by torching and fixing strips of primer in place. The overlaps should be dressed with a hand trowel to ensure perfect bonding without any opening.
