External tape for sealing expansion joints, characterized by flexibility. Made of elastomer based on SBR (styrene-butadiene rubber).

Features

• high tensile strength and elongation at break
• permanently elastic, high resilience
• resistant to the action of natural agents that are aggressive to concrete
• resistant to chemical compounds (necessary tests in special cases)
• stable dimension in contact with hot bitumen
• combined with the vulcanization method

Application

It is used for sealing joints in concrete and reinforced concrete structures, sealing expansion joints in concrete and reinforced concrete structures concreted on the construction site, e.g. underground parts of a commercial facility, underground garages, railway and road tunnels, bridges, sewage treatment plants, locks and weirs, power plants, dams.
