Nystrom's Seismic Elastomeric Twin Seal System, as its name implies offers protection of expansion joints in a seismic event. Elastomeric seals lock into. The joint seal, which is a stay-in-place form, fits various gaps, minimizing premeasuring.
Bridge expansion joint systems are directly exposed to vehicular wheel loads and, therefore, must resist dynamic forces causing fatigue and wear. In addition, these expansion joint systems must remain watertight to protect the bridge superstructure Steel Rail Profile.

Introduction In recent decades one can observe a great development of modern structural designs for bearings, Block et al.
The D series gland utilizes two elements for added protection Engineered to last as long or longer than the bridge decks they protect Provides a smooth riding surface while absorbing the impact of heavy traffic WaboModular is designed for use in heavy trafficked bridge structures requiring movements in excess of 4 inches. This joint system allows the bridge deck to move while maintaining a smooth watertight riding surface. Engineered to last longer than the bridge decks they protect, WaboModular joint system longevity comes from the steel multiple support bar system, which combines the strength to support traffic loads and impacts with the flexibility to accommodate continual structure movement. Each WaboModular is made to order and available in two styles, the WaboModular with a box seal D serieswhich utilizes a double, layer sealing element and the WaboModular with a strip seal STM Series.
