Foam Backer Rod Material 1-1/2″ Foam Rope


A unique, round, continuous-length, compressible foam material that helps ensure proper performance of the sealing system. It has an open-cell structure that allows airflow to speed sealant drying and curing from both the top and bottom. Being hydrophobic, it will not wick water. The backer rod can be used with hot or cold applied sealant material.

Foam backer rod material is an ideal, non-absorbent, compressible backup material inserted into a joint to control sealant depth and create a backstop to:

  • Allow for proper sealant tooling.
  • Allow for proper sealant wetting of the joint surfaces.
  • Yield proper bond breaker between the backup material and sealant.

Foam backer rod is a backstop material for most hot-pour sealants used to fill contraction and expansion joints of concrete highways, runways, driveways, and parking lots. It is compatible with most rubber-asphalt and coal tar-rubber polymer thermoplastic compounds.
