Flexible Expansion Joint Material for Concrete Flatwork and Paving Applications
Fast Flex Foam Expansion Joint is a lightweight, durable, closed-cell polyethylene expansion joint designed to absorb concrete movement caused by temperature changes, shrinkage, and expansion. Ideal for sidewalks, curb and gutter, driveways, paving, and commercial concrete applications, Fast Flex creates a clean separation between concrete sections while helping prevent random cracking and edge damage.
Easy to cut, handle, and install, this resilient foam material compresses under pressure and rebounds as concrete moves, providing long-lasting performance in both residential and commercial projects.
