SBS modified bitumen

Hydrophobic, resistant and durable, bitumen has set the standard for waterproofing since Antiquity. A natural and noble material, bitumen is still at the cutting edge of technology today.

In fact, SOPREMA’s research and development centres have always sought to optimize the mechanical properties of the bitumen waterproofed membranes to give them unequaled resistance against time.

A bitumen is said to be an elastomer when it is modified by synthetic materials or styrene-butadiene-styrene (SBS) polymers. The quality of SBS bitumen is determined by the properties of the added elastomers and by the formulations used in the mixture.

Benefits of elastomer bitumen:

• Its excellent elasticity;
• Its flexibility;
• Its characteristic properties at high temperatures;
• Its characteristic properties at low temperatures;
• Its excellent adherence to the support;
• Its reliable and solid waterproofing for joints;
• Its durability;
• Its non-aggressive properties;
• Its potential for development and new applications.
