Deck-O-Foam 1413035 Joint Filler | 1/2" x 3 1/2"

The Deck-O-Foam Joint Filler 1413035 is a closed-cell polyethylene expansion joint filler used for pool decks, concrete slabs, and coping joints. Measuring 1/2 inch thick by 3-1/2 inches tall and sold in 50 foot increments, it installs between concrete sections to absorb movement from expansion and contraction. A pre-scored tear strip allows the top portion to be removed for creating a sealant channel. Its non-absorbent closed-cell foam construction resists water intrusion and maintains flexibility over time. The material is designed for outdoor use in pool and concrete environments.
