Seismic Retrofit Codes Drive Modular Joint Adoption
Updated seismic design codes across California, Japan, and Turkey now require expansion joints to accommodate significantly larger movement ranges than legacy rigid designs were ever engineered to handle during a major earthquake event. Caltrans and Japan's Ministry of Land, Infrastructure, Transport and Tourism have both mandated modular multi-cell systems on new bridge construction and major retrofit projects across seismically active corridors. Mageba and Maurer have both expanded seismic-rated product lines specifically to meet these tightening requirements, and agencies increasingly specify documented shake-table testing data during vendor qualification rather than relying on calculated movement capacity alone.
Market Impact: Adds 18,000 bridges needing joints
