mageba TENSA-GRIP expansion joints are single gap joints for movements of up to 80 mm in the case of type RS, or 100 mm in the case of Type RS-LS. Type RS-LS joints feature so-called “sinus plates” on their surface, which make this increased movement possible and also reduce noise from over-passing traffic by up to 80%. The joints consist of robust steel edge profiles and replaceable elastomeric sealing profiles, which ensure long-lasting watertightness. The drainage of the joints is via the drainage system of the bridge deck.
