Expansion Joints


The Iso-Flex Factory Molded Urethane Expansion Joint Sealing System consists of premolded urethane seals, produced under factory controlled climatic conditions. Iso-Flex polymeric nosing, traffic plates, primers, bedding and bond breakers are as recommended by the manufacturer. The premolded seal is shipped to the job site in its cured state and installed in the field by adhering in place with IsoFlex 980 Polymeric Nosing compound. Traffic plates, Iso-Flex Bedding Compound, Iso-Flex Primers and bond breakers are included in the installation process as recommended to complete the installed system.


The Iso-Flex Compression Seal Expansion Joint System is an extruded, Santoprene thermoplastic rubber material. When compressed into place this system provides an excellent seal against the intrusion of moisture and debris into an expansion joint gap.

Iso-Flex "K" Series Winged Expansion Joint Sealing System consists of a thermoplastic elastomeric, membrane strip type of seal with integral perforated wings. Both expansion joint seal types are continuously bonded into a concrete blockout with Iso-Flex 900 Elastomeric Concrete header material.
