SOPREMA’s bitumen technology has been proving its durability since 1908. It is by far the most reliabletechnology in the industry. Most of SOPREMA’s waterproofing membranes are manufactured with SBS modified bitumen and include polyester, glass mat or composite reinforcement. Our experienced research and development team created and refined these membranes, and their unique superior-quality composition makes them exceptionally durable and strong.
Water repellent, long-lasting, bitumen has been the material of choice for waterproofing requirements since antiquity. Bitumen is a natural, noble material that remains on the cutting edge of technology to this day.
SOPREMA’s research and development centres have always striven to optimize the mechanical properties of bituminous waterproofing membranes in order to give them unequalled durable resistance.
Bitumen is said to be an elastomer when it is modified by synthetic compounds or styrene-butadiene-styrene (SBS) polymers. The quality of SBS-modified bitumen is determined by the properties of the added elastomers and the formulations used in the mixture.
