A Backer Rod is a cylindrical kind of foam, designed to be used in constructional projects, mainly for filing gaps or joints where materials come together.
Backer Rod are used in joints in pre-cast and cast-in-situ concrete elements to give support to the joint sealant application, aid in the correct joint sealant geometry (application depth and shape) and prevent the joint sealant from adhering to the top of the expansion joint filler board (3-way bonding), acting as a bond breaker.
