Action Wall Ties - Specialists in masonry repair and reinforcement

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, which had expanded to several times the thickness of the metal it had resulted from, in turn lifting and cracking the brickwork.

Solution
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.
