Non-cladding defects on Class 2 buildings

The establishment of Cladding Safety Victoria (CSV) by the Victorian Government is a world-leading initiative. The $600 million program is making Victorians safer by reducing the risk associated with combustible cladding on residential apartment buildings across the state.

The program has also provided a unique opportunity to examine the performance of external wall systems behind the external layer of cladding. CSV has compiled a significant body of data obtained through the program that highlights extensive non-cladding defects, that must be funded by owners.

As of May 2023, of the 359 buildings funded by CSV which have combustible cladding, nearly 50 per cent have non-cladding defects (i.e., structural, fixing and sealing, water ingress), and of these nearly 80 per cent were identified to have water/moisture related structural damage, which are indicators of the presence of mould.

This is more extensively covered in CSV’s research analysis below.

Research analysis

Cladding Safety Victoria has published a research analysis with findings relating to building defects other than cladding, including photographs of various defects found.
