EXPANDOFLEX Expansion Tape
high-performance, thermoplastic elastomer joint tape
EXPANDOFLEX Expansion Tape is a high-performance thermoplastic elastomer-based expansion joint tape.
Engineered for superior flexibility and long-term performance in high-stress environments, EXPANDOFLEX accommodates structural movement, making it ideal for sealing construction and expansion joints in tunnels, swimming pools, basements, and wastewater facilities. Its thermoplastic elastomer core offers outstanding resistance to UV exposure, chemicals, plant root intrusion, and biological attack, ensuring reliable waterproofing under extreme conditions. When bonded with PROBOND 1100 epoxy adhesive, it forms a permanent, watertight seal across substrates such as concrete, steel, and masonry, delivering exceptional protection against moisture ingress and environmental stress.
