X-FOAM™
Flexible, Lightweight, Concrete Expansion Joint Filler
DESCRIPTION
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.
USES
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.
FEATURES/BENEFITS
- Flexible, lightweight, and can be formed around curved objects.
- Can be used with both cold and hot applied joint sealants
- 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®

APPLICATION
Attach X-FOAM securely to the existing concrete slab, coping, or form with tape or mechanical fasteners prior to pouring the next slab. Make sure that X-FOAM is level with the desired slab surfaces before finishing.
When using with hot-applied joint sealants, apply against the factory-formed edge. If not possible, please contact W. R. MEADOWS.
