W R Meadows X-Foam™ Closed-Cell Joint Filler


X-FOAM expansion joint filler is a flexible, lightweight, non-staining, polypropylene, 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.


X-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.  The use of X-FOAM expansion joint combined with proper sealing and joint design per American Concrete Institute guidelines can help reduce unwanted cracking and early joint edge deterioration.


•    Flexible, lightweight, and can be formed around curved objects.

•    Easy to carry.

•    Easy to install.

•    Can be used in interior or exterior applications.

•    May be easily scored with a razor tool to create a void for POURTHANE® or DECK-O-SEAL®
