Product Information


This is a 1/2 inch thick by 4 inch foam Expansion Joint Filler designed to be inserted into concrete expansion joints before a self leveling finishing product is used. Please note that this product comes in 50 foot rolls. So orders for over 50 feet would be fulfilled by 50 foot rolls and cut lengths to accommodate the quantity ordered.

DECK-O-FOAM 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, economical, compressible foam that offers an extended service life in both interior and exterior applications.

DECK-O-FOAM 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 an economical alternative as an expansion joint in all concrete paving projects. It is compatible with all currently available cold-applied sealants

DECK-O-FOAM 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. Attach DECK-O-FOAM securely to the existing concrete slab, coping, or form with tape or mechanical fasteners prior to pouring the next slab. Make sure that DECK-O-FOAM is level with the desired slab surfaces before finishing. If specifications require the use of a cold-applied sealant, remove the pre-scored strip and apply the sealant following the manufacturer's instructions.
