concrete toe reinforcement & re-tie infill walls
The subject of this case study was a 12 storey concrete frame building with brick infill walls believed to have been constructed in the 1960s.
Problem
The building was of a concrete frame and floor construction, with cavity brickwork infill walls. The infill walls were constructed with an external brick skin on a single course high concrete toe that was visible above the fenestration openings and balcony soffit.
a. Cracking movement was noted to the infill walls.
b. Sections of the concrete toes were found to be failing along with sections of the external brickwork not supported by the concrete toe.
c. A wall tie deficiency was evident.

SolutionAWT completed a remedial scheme providing a viable repair by the introduction of 10mm stainless steel reinforcement to the concrete toe, remedial wall ties and general brick repairs.
