SUPERFLEX Joint Tape
flexible waterproofing tape
FORSPEC SUPERFLEX JOINT TAPE is a premium flexible waterproofing tape designed for sealing dynamic joints, precast panel connections, and critical transitions.
Featuring over 370% elongation, dual felt-laminated surfaces, and >1.5 bar water pressure resistance, FORSPEC SUPERFLEX JOINT TAPE ensures long-term performance under thermal and structural movement. Ideal for wet areas, balconies, rooftops, and retaining walls, this tape integrates seamlessly with cementitious, polyurethane, and acrylic membranes. Available in widths from 100–700 mm, it meets AS4654.2 standards and is UV stable, VOC-free, and easy to embed.
