CLOSED CELL POLYETHYLENE FILLER

Description

Corkjoint Jointflex Backer Rod is manufactured from closed cell polyethylene, are non-absorbing, are U.V resistant and have excellent weatherability properties. It is a type of material that is commonly used in construction projects as a backing material for sealing joints, gaps, and cracks in various surfaces. It is particularly useful in applications where a flexible, compressible material is needed to create a watertight seal.

Uses

Jointflex 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.
