FORZAFLEX RR Torch-On Sheet Membrane 1m x 10m

• Planter boxes and raised planting beds
• Green roofs and landscaped podiums
• Plaza decks beneath soil and planting systems
• Retaining walls adjacent to landscaped areas
• Below-ground structures requiring root resistance
• Roof and podium areas where planted and exposed zones adjoin and a single cap sheet is preferred
• Exposed roof areas within a landscaped scheme, where the micro-mineral surface remains the finished surface

Surface suitability

• FORZAFLEX BASE 3mm (the standard substrate; fully bonded, inspected and free of defects, blisters and unfused laps, no priming required)
• Concrete (fully cured minimum 28 days, Concrete Surface Profile 3-6, dry and sound, primed with FORZAPRIME)
• Cement render and screed (fully cured, sound and non-friable, dry at the time of priming, primed with FORZAPRIME)
• Masonry and blockwork (sound, joints struck flush and made good, primed with FORZAPRIME)
• Metal (rigid, clean, free of oil, oxide and mill scale, primed before membrane installation)
• Timber and combustible substrates (torch application direct to a combustible substrate is prohibited; a non-combustible overlay board must be installed first)

NOT A TRAFFICABLE MEMBRANE. Certified abrasion depth is 0.539 mm against a 0.2 mm pedestrian limit, so the membrane is suitable for MAINTENANCE ACCESS ONLY; where pedestrian or vehicle traffic is required, design a separate trafficable wearing surface over the membrane. Root resistance protects the membrane; it does not substitute for a correctly designed planted build-up, and protection board, drainage cell, filter fabric and drainage falls must all be provided. Root resistance is not classified under an Australian Standard - where a project specification requires certified root resistance to a nominated test method, confirm the current position with FORSPEC Technical Services. Never place growing medium, soil, ballast or planting directly on the membrane; a protection layer is mandatory. Classified CLASS I, low extensibility; where the design requires a Class II or Class III membrane for movement accommodation, specify a higher-class FORSPEC membrane. Torch application direct to combustible substrates is PROHIBITED; a non-combustible overlay board must be installed first. Torch-applied work is hot work and must not proceed without a hot work permit, a fire watch and the fire safety measures in the TDS. Do not torch onto wet, damp, green or uncured substrates, or onto wet or uncured primer. Do not overheat; excessive heat degrades the bitumen, damages the polyester reinforcement and may impair the anti-root additive system. No cold joints, fish-mouths or open seams are permitted at any lap - a lap that has not fused is the pathway a root will find. Not compatible in direct contact with polystyrene insulation, PVC membranes or plasticised sheet materials without an approved separation layer. Bitumen fume is classified as a suspected carcinogen.
