EXPANDOFLEX FT JOINT TAPE
felt-laminated, thermoplastic elastomer joint tape
Expansion joint system with integrated fabric backing for compatibility with waterproofing membranes.
EXPANDOFLEX FT Expansion Tape 250mm x 25m is a felt-laminated, thermoplastic elastomer joint tape designed for structural and movement joints. With dual bonded felt edges, EXPANDOFLEX FT Expansion Tape 250mm x 25m integrates seamlessly into liquid or sheet-applied membrane systems. Engineered for high flexibility, UV stability, and chemical resistance, EXPANDOFLEX FT Expansion Tape 250mm x 25m is ideal for tunnels, retaining walls, slab joints, parapets, and waterproofing transitions requiring long-term movement accommodation.
