Our sealing solution for expansion joints

For decades, experts around the world have relied on our Soba expansion joint systems to seal expansion joints effectively and permanently.

Building components are constantly exposed to extreme stresses due to temperature fluctuations, earthquakes and other physical conditions. These can affect the volume of the substance of the buildings and the building materials and lead to signs of fatigue or even breakage. Improper sealing of expansion joints can lead to complex and costly repairs.

Early planning to accommodate cyclical 3D-movements along the joints is crucial. Appropriate structural protection of the building envelope contributes to sustainable and high-quality solutions.

Soba FlamLINERedLINE and EpoLINE: These joint tape systems made of elastomers are specially designed for three-dimensional joint movements. Depending on the type, the lateral adhesive flanges are flamed into bituminous sealing systems and/or applied directly to the substrate with liquid plastic or epoxy resin adhesive.

The most important product advantages:
Factory prefabrication for quick and safe installation on site
Low thickness
Absolute flatness
High elasticity with movement compensation up to 240 mm (depending on tape type)
