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.
