Expansion Joints for Roadways, Bridges, Parking Garages, & Other Structures

Expansion joints play a critical role in the long-term health of bridges and multi-level parking structures, and other critical infrastructures such as dams and airports. When pavement expands or contracts, the rubber seal within the expansion joint allows for movement while maintaining a watertight seal between pavement sections, or between the pavement and bridge structure.

Custom-designed and fabricated to accommodate structural movements, expansion joints ensure the continuity of vehicular traffic while maintaining a watertight seal on the deck. They also prevent structural damage by absorbing movements such as expansions and rotations that result from loads caused by traffic, temperature variations, strong winds or earthquakes.

HK expansion joints meet or exceed compliance with MTO, MTQ, and CHBDC in Canada and AASHTO in the U.S. Made from neoprene or EPDM rubber compounds, HK expansion joints have high tensile strength and resist the effects of ozone, UV exposure, and extreme weather.

Some of the more common specifications that can be considered for these expansion joint applications are the following:

• ASTM D2628 – Standard Specification for Preformed Polychloroprene Elastomeric Joint Seals for Concrete Pavements
• ASTM D5973 – Standard Specification for Elastomeric Strip Seals with Steel Locking Edge Rails Used in Expansion Joint Sealing
• MTO / OPSS 1210 – Material Specification for Deck Joint Assemblies
