Joint tapes

Our sealing solution for expansion joints

Our joint tapes have been used all over the world for decades to absorb joint movements, seal construction joints and connect and seal bitumen seals by force-fitting.

Building components are constantly exposed to extreme stresses, such as temperature fluctuations, earthquakes and other physical conditions. These affect the volume and composition of the materials used and the substance of the buildings and can cause fatigue or fractures with catastrophic consequences.
To avoid damage, it is necessary to think about the ongoing absorption of cyclic movements (3D movements) along the joints between separated building structures when sealing. At a structural level, the building envelope should, wherever possible, be protected with sustainable, high-quality solutions that offer long-lasting effect.
Soba FlamLINE, RedLINE and EpoLINE are joint tapes made of synthetic rubber. They are used to bridge three-dimensional joint movements in bitumen seals and between concrete components. Their most important product advantages are their low thickness, absolute flatness and high elasticity, with movement compensation of up to 240 mm.
