Cavity Wall Tie Failure - Twistfix Solutions
Missing or rusted wall ties seriously compromise the stability of a building, a fact dramatically highlighted in a recent case of falling brickwork caused by cavity wall tie failure in Lancashire. The outer brick walls of the buildings suffered a near-fatal collapse during a period of high winds of up to 70mph.
A number of properties were damaged in the collapse, caused by high winds coupled with a serious lack of tie irons and with high levels of corrosion affecting the few cavity ties that were built into the wall during construction of the terraced houses. The fallen brickwork lay on the pavement next to the front wall of the houses, which were so compromised due to their neglected wall ties that they could not stand up to the onslaught of the wind.
Wall tie failure is not a problem confined to the UK; collapsed walls that result from missing or rusted ties are a problem that regularly affects homes in countries as far apart as Holland, USA and Australia. Indeed anywhere where cavity walls are the traditional method of construction can be at risk of tie failure due to poor workmanship that leaves insufficient ties to resist wind loads or a natural aging process in which metal ties rust and loose strength.
