SOPRAWALK™ is an SBS-modified bitumen ply used to create a walkpath and protect the field membrane from traffic. SOPRAWALK is composed of a proprietary formulation of elastomeric styrene-butadiene-styrene (SBS) polymer modified bitumen and is reinforced with tough, dimensionally stable non-woven polyester mat. The topside surfaced with ceramic coated granules while the underside is surfaced with fine mineral aggregate to facilitate heat welding, cold adhesive and hot asphalt applications.

Installation

Prior to installation, unroll SOPRAWALK onto the roof surface and allow to relax. Place SOPRAWALK in desired position and back roll the product. SOPRAWALK is heat welded to approved substrates or applied with approved cold adhesive or hot asphalt following manufacturer specifications. SOPRAWALK is then rolled into the cold adhesive or hot asphalt and subsequently rolled with a weighted roller. Refer to the SOPREMA® SBS Roofing Manual for additional application guidelines.
