Joint systems from Aestuver®

The targeted planning of expansion or movement joints in the building structure can prevent constraining forces from occurring and damaging the structure. These joints between building components must be sealed with flexible materials. These absorb the movement of the joints, ensure they are sealed and maintain the fire resistance. AESTUVER offers high-performance fire protection joint systems for tunnels.
