mageba’s TENSA-CRETE single gap expansion joints provides a maximum displacement of 80 -100 mm. the Sinus Plates used in the RE-LS type provides the 20 mm excess displacement and reduces traffic noise up to 80%. TENSA-CRETE steel edge profiles are anchored in mageba’s quick-hardening watertight concrete. An advantage of this expansion joints is its quick and cost efficient installation, which is a result of being anchored in the surface of the pavement. Due to the use of quick-hardening polymer concrete, this system makes utilization possible in a few hours from installation. The drainage of the joint is via the drainage system of the bridge deck.
TENSA-CRETE expansion joint is applicable for concrete and asphalt decks and can be installed on existing or new bridges. This expansion joint is beneficial for retrofit of existing bridges, due to its shallow structural depth and quick installation.
