Corroded mild steel cavity wall ties

An 1950s estate of street housing with corroded mild steel cavity wall ties – remedial wall tie treatment

The subject buildings form an estate of terraced and semi-detached social street housing of cavity construction under pitched roofs.

The wall tie problem

The existing wall ties viewed were found to be mild steel vertical twist ties, commonly known as fishtail ties.

The galvanised coating was found to be in varying stages of corrosion, blackened with red rusting noted.

The corrosion of the embedded mild steel wall ties had resulted in the forming of ferrous oxide (rust), which had expanded to several times the thickness of the metal it had resulted from, in turn lifting and cracking the brickwork.

AWT completed a remedial programme providing a viable repair through the introduction of a pattern of remedial wall ties and isolating the existing ties, together with general brickwork repairs and re-pointing.
