GREENZONE BACKER ROD

GREENZONE® Backer Rods are an integral component of sealant joints and provide three main functions that allow the sealant joint to perform and stop the ingress of pests – in particular ants cockroaches

and termites.

GREENZONE® Backer Rods are ideal as a vertical and horizontal joint filler in concrete, masonry substrates between precast concrete panels, interior walls, sealing skylights, shop fronts and curtain wall construction, it can also be used in areas such as, dust sealing, sealing electrical control boxes, truck and trailer construction. The chemically treated Greenzone Backer Rod will stop the ingress of ants, cockroaches & termites into any structure where it is installed.

The backer rod acts as a bond breaker, preventing what is commonly referred to as ‘three sided adhesion’. This is when the sealant is adhered to the bottom and both sides of the joint. In this configuration the sealant cannot move nearly as well as when it is only bonded to the sides of the joint.

The backer rod supports tooling so after installation of material the sealant can be pushed to the bond line with a spatula, ensuring wet-out of the sealant to the substrate.
