What is SUPERFLEX Joint Tape used for?

SUPERFLEX Joint Tape is a wider, longer joint reinforcement tape for dynamic joints, precast panel connections, and critical transitions in wet areas, balconies, rooftops, and retaining walls. The 50m roll length suits commercial-scale projects.

150mm width by 50m roll length (other widths 100-700mm available). Approximately 0.7mm thick. Blue TPE core with white fleece flanks. 370%+ elongation. Water pressure resistance greater than 1.5 bar.

Embed in the wet first coat of liquid membrane (cementitious, polyurethane, or acrylic) along the joint. The TPE core spans movement; the fleece flanks bond to the membrane. Easy embed - no float or delamination.

Which membranes work with it?

Compatible with Forspec cementitious (988, 989 CWP), polyurethane (929 HV/SL, 925, 906 WPU), and acrylic membrane systems. The 150mm width handles most slab edge and movement joint applications.

Standards compliance?

Complies with AS4654.2 for external waterproofing reinforcement. Use for AS-compliant balcony, podium, and external deck waterproofing detailing.

How to Use

Centre the tape over the joint in the wet membrane base coat and press it in with a steel trowel or spatula, working from the centre outwards, then overcoat to fully encapsulate it.Confirm substrates are clean, dry, structurally sound and free of laitance, dust, oil, grease, paint, sealers and curing compounds
Grind or lightly abrade dense, burnished or coated surfaces to expose sound substrate, then vacuum the area thoroughly
Make junction zones smooth and continuous for a minimum of 200 mm in every direction from the corner, including the wall upturn
Cut out and reinstate any weak, hollow or drummy render or screed
Reinstate defects, voids and blowholes with FORBUILD 100 or FORCRETE 100, finished flush and cured
Remove all loose fasteners, screws, nails and debris from wall and floor sheet surfaces
Confirm any required primer has been applied and is fully dry
Pre-fill cracks and static joints wider than 3 mm with ACTFLEX 75FC or ACTFLEX MS PRO and allow to cure
Apply a generous, continuous base coat of the specified FORSPEC membrane along the full length of the joint, wide enough for the full tape width plus margin on both sides
While the membrane is still wet, centre the tape over the junction so the elastomeric centre spans the joint and the felt faces lie flat on both planes
Press the tape into the wet membrane with a steel trowel or spatula, working from the centre outwards to expel air, wrinkles and dry zones
Overlap tape ends by a minimum of 50 mm, fully embedded in membrane at the lap
Cut internal corners at 45 degrees and lap or mitre neatly, keeping the centre of the tape continuous around the corner
Pre-form or cut external corners to the corner shape with continuous overlap, fully saturated on both planes
Join factory-preformed corner units to the running tape with a minimum 50 mm overlap and full embedment
Allow the base coat to partially set, then apply the second coat over the entire tape length, fully encapsulating the tape
Inspect for hollow zones, wrinkles, dry felt and lifted edges, and cut out and re-detail any defective length
Flood test after full cure of the membrane system, then tile or cover

Technical overview

FORSPEC SUPERFLEX JOINT TAPE is a three-layer thermoplastic elastomer waterproofing joint tape faced with flexible felt laminate on both sides, for dynamic movement joints, cold joints and the critical transitions where a waterproofing system is most likely to fail. A systematic perforation pattern along both felt edges lets liquid membranes filter through the tape and key mechanically from both directions. It is a detailing component and is not itself certified to a membrane standard, so AS/NZS 4858 does not apply to it. Compliance is established by the certified FORSPEC membrane system in which the tape is embedded. No accredited certificate is currently held on file for the tape properties, and VOC certification is not currently held.

Key applications

Wet areas - bathrooms, laundries and commercial kitchens
Balconies, terraces, rooftops and planter boxes
Retaining walls, swimming pools and water tanks
Horizontal and vertical wall-to-floor junctions
Cold joints, chamfers and precast panel seams
Corner junctions and transitional zones as a high-performance transition tape
Under-tile systems using C2-class adhesives

Surface suitability

Concrete (smooth and free of surface ridges, sharp projections, fins and voids)
Render (fully cured, crack-free and solidly bonded)
Screed (fully cured, crack-free and solidly bonded)
Building boards and sheet substrates (installed and fastened per the sheet manufacturer's instructions, all loose fasteners and debris removed)

Not a stand-alone waterproofing product. The tape performs only as a reinforced detail within a complete FORSPEC waterproofing system and must not be left exposed. Never embed dry: the membrane must fully wet out the tape from beneath and be applied over it, or a dry-laid tape will float, bridge and debond. Cracks and static joints wider than 3 mm must be pre-filled with ACTFLEX 75FC or ACTFLEX MS PRO before the tape is installed. Not a substitute for a designed movement joint - dynamic structural joints require the joint detail nominated in the project design. Do not install over frosted, damp or contaminated substrates, or where condensation is present. Do not stretch the tape during installation, as an installed tape under tension will pull out of the junction as the membrane cures. Tile adhesive may be applied only once the waterproofing membrane has fully cured. Confirm compatibility between the tape and the specified membrane with a FORSPEC technical representative before use.
