Product:

1/2 X 4" Flat Expansion Joint Foam. Charcoal Color Closed Cell Polyurethane. 50 foot rolls. 9 Rolls/Bag (450 feet). Price/Bag. (shipping leadtime 1-3 business days)

Description:

A flat backer rod foam design to create quality concrete expansion joints quicker and easier that traditional wood or composite spacers. The unique top tear strip is removed (during trowelling of fresh concrete) to quickly create an exact top joint shape for sealants. The polyurethane material does not adhere to sealants, so proper 2-sided joints are created and the joint meets sealant joint specifications requireing a bond breaker.

Features:

  • Highly Bendable: Easily creates tight radius / complex joints.
  • Lightweight: Over 11 times lighter than traditional products
  • Resistant to Moisture: Virtually zero water absorption
  • Termite Resistant: Does not facilitate destructive termites.
  • Environmentally Friendly: Material is CFC and HCFC-free
  • Temperature Compatible: Excellent range for cold or hot climates
  • Sealant Compatible: Works with common sealants.
  • Made in USA

Physical Properties:

  • Material: Closed Cell Polyurethane foam.
  • Color: Charcoal (contrasts with concrete for good visibility)
  • Bond Breaker: Meets sealant and caulking specifications as a bond breaker
  • Extrusion: 0.12 (in), ASTM D545-05
  • Compressive Strength: 14.9 PSI, ASTM D545-05, Suffix D @ 50%
  • Compression Set: 18.3 (%), ASTM D3575-00 Suffix B
  • Tensile Stress: 103 (psi), ASTM D3575-00 103 Suffix T MD/CMD
  • Tear Resistance: 14 (lb/in), ASTM D3575-00
  • Density Range: 2 (lb/ft3), ASTM D3575-00 (nominal)
  • Water Absorption: 0.001 (lb/ft2) ASTM D545-05
  • Meets Application Requirements of: ASTM D-7174 Standard Specification for preformed closed cell polyolefin expansion joint fillers for concrete paving and structural construction.
  • Exceeds ASTM Standard D-7174.
  • Limitations: Not UV Stable. Not compatible with hot pour sealants or some chemical sure sealants.

Installation Instructions:

  • Unroll and cut to length. Remove any rough edge material from adjacent surface, so that foam can seconcrete.
  • Attach tear-side-up to the adjacent material before pouring next concrete section. Attachment can be made with construction adhesive, nails or staples. Be sure that the top of the expansion joint foam is set at the top of the intended concrete pour.
  • Expansion Joint material includes a built-in “tear-off” strip. Place “tear-off” strip facing up if caulking is desired after concrete hardens. Put “tear off” strip facing down if no caulking is planned.
  • Pour concrete and finish. During trowelling / finish stage, remove tear-off strip. Then finish concrete joint edges.
  • After concrete cures, clean joint area, and fill with sealant, to a height below the top surfaces. The joint should be no deeper than its width, preferably depth is 1/2 the joint width. See Example: Joint Placement and Shape
  • Options:

    • Height: 3", 4", 6", or 8".
    • Thickness: 1/4, 3/8 and 1/2".
