About Extragum SBS
Extragum SBS is an elastomeric modified bitumen membrane used for a wide range of waterproofing applications. It is manufactured in a high-tech calendaring process, which saturates and coats a heavy duty polyester carrier with an SBS elastomer-modified bitumen compound. The SBS modifiers improve the thermal, chemical and ageing properties of the bitumen, while the non-woven polyester carrier acts as reinforcement, boosting tensile strength, elongation and tear resistance.
Surface finish
The lower surface of the membrane is laminated with a thin thermo-fusible polyethylene burn-off film. The upper surface is available in a range of finishes including coloured slates, aluminium foil, sand and polyethylene film.
Key features
- Absolute impermeability to water
- High chemical resistance to alkaline solutions, light acidic solutions and bacteria
- Thermal resistance across a wide range of temperature fluctuation
- Excellent UV resistance when the surface is finished with slates
- Ease of adhesion to a wide variety of surfaces
- Suitable for above and below ground use
Application
Extragum SBS is used across a wide variety of waterproofing requirements, particularly where the membrane is subject to constant movement and high stresses:
- Roofing and re-roofing, single or multi-layer systems
- Sloped and flat roofs
- Metal decks subject to significant movement
- Tunnels, wet areas, swimming pools and toilets
- Foundations and underground structures
