SBS Modified-Bitumen
Revolutionary styrene-butadiene-styrene (SBS) modified bitumens were developed by Siplast in partnership with Shell Chemical of Europe in the late 1960s. This elastomeric blend of asphalt and SBS is highly durable and capable of exceptional elongation and recovery properties over a wide range of temperatures. This resilient blend provided the foundation for Teranap, Siplast's two-ply waterproofing system based on proven roof membrane design. With enhanced flexibility, elasticity, and puncture resistance, the Teranap Waterproofing System is engineered to meet the intense demands of plaza deck applications for years.
