Description
Walkway membrane applied on a two-ply roof system.
UNITS PER SKID: 30
Material Use:
SOPRAWALK is a cap sheet membrane designed for use as a protective, walkable surface on roofing systems. It is specifically engineered to provide a durable, granule-surfaced finish that can withstand pedestrian traffic. SOPRAWALK is used as the top layer in a multi-ply SBS-modified bitumen roofing system, offering both waterproofing and surface protection.
System Components:
SOPRAWALK is part of a complete SBS-modified bitumen roofing system. It is installed as the cap sheet over a two-ply base system. The system requires the use of ELASTOCOL 500 primer on the substrate prior to installation to ensure proper adhesion. The SOPRAWALK membrane itself is composed of SBS-modified bitumen reinforced with non-woven polyester, with a black granule surface and a thermofusible plastic film on the underside for heat-welded application.
Applications:
SOPRAWALK is intended for use on flat or low-slope roofs where pedestrian access is required, such as maintenance walkways or rooftop terraces. It is suitable for commercial, industrial, and institutional buildings where a durable, traffic-resistant surface is needed over a waterproofing membrane.
Application Details:
- Installation Method: SOPRAWALK is installed using a heat-welding technique with a propane torch.
- Primer Requirement: The substrate must be primed with ELASTOCOL 500 before membrane application.
- Surface Preparation: The surface must be clean, dry, and primed.
- Dimensions: Each roll measures 8 m x 1 m (26 ft x 3.3 ft).
- Thickness: Minimum thickness before heat conditioning is 4.0 mm (157 mils); after heat conditioning, 3.3 mm (130 mils).
- Back Surface Coating Thickness: Minimum 1.0 mm (40 mils).
- Mass per Unit Area: 5.27 kg/m² (108 lb/100 ft²) before heat conditioning.
- Low Temperature Flexibility: -18 °C (-0.4 °F).
- Compound Stability: Up to 121 °C (250 °F).
- UV Resistance: SOPRAWALK is UV-resistant due to its granule surface, which protects the membrane from degradation.
- Puncture Resistance: Passes standard puncture resistance tests.
- Granule Embedment: Less than 2.0 g (0.07 oz), indicating strong granule adhesion.
Special Notes:
- SOPRAWALK is not a standalone waterproofing membrane; it must be installed over a two-ply SBS-modified bitumen base system.
- The product is designed for pedestrian traffic only and is not suitable for vehicular traffic.
- Rolls must be stored upright with the selvedge side on top and protected from UV exposure if stored outdoors.
- For optimal performance, installation should be conducted in dry weather conditions and within the temperature range that allows proper heat welding.
- Always consult with a SOPREMA representative for complete installation guidelines and compatibility with other SOPREMA roofing components.
This material is ideal for creating durable, walkable surfaces on SBS-modified bitumen roofing systems, particularly in areas requiring regular foot traffic for maintenance or access.
