GusjoinT® backing rods are heat-resistant, closed-cell, rot-resistant polyethylene backing rods for use in concrete and asphalt joints. They ensure accurate joint depth control and reliably prevent three-sided adhesion of the joint sealing compound.
Suitable for all hot- and cold-applied joint sealing compounds, they provide high flexibility and elasticity within the joint.
