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 the carrier with an SBS elastomer-modified bitumen compound. The SBS modifiers improve the thermal, chemical and ageing properties of the bitumen, while the 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
