Recent Cyclones

Category 4 Tropical Cyclone Debbie crossed the Queensland coast north east of Airlie Beach around midday on Tuesday 28 March 2017. CTS teams investigated the performance of houses; larger residential structures such as apartments, strata properties and resort accommodation; commercial and public buildings; and sheds. The study area included the communities of Bowen, Proserpine, Airlie Beach, Hamilton Island, Dingo Beach, Wilson’s Beach and Conway Beach.  The buildings within the study area were estimated to have experienced wind speeds lower than their relevant design wind speed. The following report provides recommendations to improve the performance of building structure and cladding systems.

Recent Damage Investigations

Recent CTS damage investigations have highlighted problems with flashing details on buildings, leading to water ingress and often significant internal damage. The house on the left has lost a flashing on the windward wall. The Cyclone Testing Station recommends that suppliers of flashing materials ensure that proposed detailing has been fully documented.
