The Challenge ASRS was consulted to conduct a wall tie investigation at a large commercial property, which showed no obvious signs of movement except for one masonry panel that had leaned outward by 80mm at the top. After an extensive survey, it discovered that the inner and outer leaves of the masonry lacked sufficient wall ties to connect the two skins effectively. The Solution ASRS performed numerous tests and endoscope surveys to evaluate the existing ties. Pull-out tests were conducted on various remedial wall ties, with the Helifix resi-tie yielding the best results, achieving pull-out ratings of over 2.5 kN. The masonry drilled using only a 12mm hole, and the tie was installed with portable drills, followed by resin fixation on the outer leaf.
