SBS Membrane Overview 

 

SBS waterproofing membrane combines expertly blended SBS (Styrene-Butadiene-Styrene) elastomeric modified bitumen with high quality reinforcement carriers, produced by state of the art machinery. The result is a range of world class leading SBS waterproofing membranes, providing long term and reliable protection for buildings and civil engineering. The excellent product range offers flexibility in design and aesthetic finish to designers and specifiers whilst ensuring guaranteed performance, often for the life of the building.

 

The membrane is composed of SBS modified bitumen, which is oxidized bitumen modified with synthetic rubber. This increases the degree of elasticity by over 1000%, flexibility is present in temperatures below -30C and heat resistance exceeds temperatures of 110C. Its strength lies in the reinforcement being composed of 180 qsm non-woven polyester. This gives the membrane its superior mechanical resistance. Combining these two products has enabled us to create waterproofing systems that adapt to the needs and conditions of each specific roof.

 

The optimum elastomeric content and carrier reinforcement can tolerate repeated movement and stresses imposed by building movement and climatic extremes. SBS elastomeric waterproofing membrane is suitable for flat roofs, low pitch roofs, barrelled/domed structures, terraces, courtyards, basements, foundations and vertical surfaces.

SBS - Styrene Butadiene Styrene 
  
Asphalt or bitumen is still the best known waterproofing materials. However, it has poor aging characteristics, is brittle in cold weather and fluid in hot weather and has no resistance to fatigue. Elastomeric compounds such as SBS (Styrene-Butadiene-Styrene) substantially improves these properties. SBS thermoplastic rubber is flexible and has the memory to return to its original form. SBS forms a rubber matrix of butadiene when intensively mixed with molten bitumen. SBS is manufactured as white granules which are finely ground before adding to molten bitumen. A phase inversion takes place from the bitumen phase to a homogeneous elastomeric phase. The styrene end blocks act as links holding the elastomeric matrix together. The styrene and butadiene matrix increase the flow characteristics and improve the low temperature flexibility and fatigue resistance of roofing asphalt.
