Expansion Joints choices for large and seismic joint gaps in parking decks have been limited to cover plates and self-centering-bar systems. Neither of these systems is watertight. Both of these systems are noisy. The RandD goals for the SJS SYSTEM from EMSEAL were: 1) Watertight; 2) Traffic and Load Durable; 3) no invasive anchors; 4) no hard connections to concrete; for joint openings larger than 4-inches (100mm); and 5) Quiet.

This video shows a 3-year old SJS SYSTEM installation in a shopping mall. The failing and terribly noisy self-centering bar system was replaced in phases. The result is a dramatic difference in noise between the yet-to-be replaced older systems and the SJS seismic expansion joint system.
