The subject building started as a 1960s eight-storey commercial concrete frame building that was converted to 50 flats in 2004. Dampness, poor insulation and instability to the brickwork flack walls and brickwork features were constantly experienced and reported.
Action Wall Ties was instructed to engage a firm of consulting structural engineers to jointly undertake an intrusive inspection in order to establish a defects report on our findings to enable the design of a suitable remediation.
Following AWT and Conisbee’s intrusive investigations a remedial scheme was developed that proposed providing temporary support at each floor beam, with AWT developed props, to accommodate the continuous removal of brickwork to clean the cavity and install a cavity tray, followed by the reinstatement of the brickwork, together with remedial wall ties and bed joint reinforcement to assist in supporting the brickwork.
Once the intrusive survey has been completed, remedial wall ties were installed and the areas of bridged cavity identified for cleaning to the foot of each infill wall line.
