Sika - internal sealing tape for Sika Elastomer FM expansion joints

Flexible, internal tape for sealing expansion joints in reinforced concrete and concrete structures. Made of elastomer based on SBR (styrene-butadiene rubber).

Features

• permanently elastic tape with high elasticity
• highly resistant to stretching and elongation at break
• resistant to the action of natural agents that are aggressive to concrete
• resistant to many chemical compounds
• suitable for sealing structures exposed to high stresses and water pressure
• dimension stability in contact with hot bitumen
• ready-to-install, prefabricated sealing systems
• joined by vulcanization (butt welds on the construction site)

Application

The tape is used for sealing gaps in reinforced concrete and concrete structures, sealing expansion joints in concrete structures made of reinforced concrete and concrete, e.g. in underground parts the facility in commercial, underground garages, road and rail tunnels, bridges, power plants, sewage treatment plants, locks and weirs, dams and dams. The tapes comply with DIN 18197 and DIN 786.
