Superstructure Repair

A pair of semi-detached houses in Oxfordshire of cavity wall construction with external cracking to all elevations.

The houses are constructed from calcium silicate bricks, which are prone to cracking caused by thermal or moisture induced movement.

After discussions with the client a reinforcement scheme was designed by the Bersche-Rolt engineer to provide resistance to future cracking.

Bersche-Rolt’s patented masonry reinforcement system was installed in the outer leaf by in-house site personnel in order to repair and strengthen the cracking. All prepared joints were repointed to match the existing finish.

A movement joint was also installed between the two properties to prevent future thermally induced cracking.
