Closed cell polyolefin foam expansion joint filler

Expansion joint filler is a flexible, lightweight, non-staining, polyethylene, closed-cell expansion joint filler. It is a chemical-resistant, ultraviolet stable, non-absorbent, low density, cost-effective, compressible foam that offers an extended service life in both interior and exterior applications.

Expansion joint filler is supplied with a convenient, pre-scored removable strip to provide a uniform sealing reservoir in the joint. It also serves as a sealant bond-breaker and provides a cost-effective alternative as an expansion joint in all concrete paving projects. It is compatible with all currently available cold-applied sealants.

Expansion joint filler is ideal for use as an expansion, contraction, and/or isolation joint in swimming pool decks, curb and gutter work, floor slabs, pavement patch repair, sidewalks, driveways, plazas, parking decks, highways, and airport runways.
