Concrete spalling, brick rotation and thermal movements.

This residential complex built in the 1960’s and consisting of multiple levels of face brickwork was in urgent need of remedial works to its façade. Concrete spalling, brick rotation and thermal movements were resulting in this building being distressed. This stress left the appearance of a significant cracking and bulging of the façade.

BellMont was engaged to inspect and identify the causes and establish a suitable remedial option.

Remedial Building Services was engaged to implement the solution which was provided by BellMont.

The internal surfaces of the concrete frame were corroding (reinforcing steel) resulting in expansive forces being applied to the brickwork.

The solution—to undertake the necessary concrete repairs and construct a mechanism within the façade to accommodate future movements. Horizontal joints were expressed into the façade together with the building of load bearing slab edges. New cavity flashings were installed to ensure that water within the cavity was being expelled outward and not draining into the cavity.
