Features
Corrotech Backing Rod is a non-extruding, non-absorbent, closed cell polyethylene backing rod designed for use as a backing material, to provide support and accurate depth measurement for subsequent joint sealant materials for expansion joints in concrete, and is particularly recommended for joints in brickwork, blockwork and masonry in accordance with BS 5628 – 3 : 2001 The Code of practice for use of masonry.
Corrotech Backing Rod is bitumen free, rot proof and has high compression & recovery therefore accommodating thermal and other structural movements in structures, without the risk of load transfer or reflective cracking through the designed joint.
Uses
Corrotech Backing Rod is typically used as a backing material for sealants in expansion and movement joints between concrete, brickwork, blockwork, and masonry where bituminous fibre boards are not recommended.
Corrotech Backing Rod is highly recommended for joints in water retaining or excluding structures.
