Ministerial Specifications for waterproofing wet areas in SA were updated in May 2012. 
There is still low awareness about these specifications. In the past we have mailed out the specifications to all tilers and apprentices attending FCTA. Just in case, the specifications can be downloaded by following this link. Questions about state requirements, are sometimes asked during technical interviews for a contractors licence. If you are planning on undertaking any projects that involve waterproofing, take time to read through the state requirements, the Building Code of Australia (BCA) requirements as well as the manufacturers instructions supplied when purchasing waterproofing products/ systems.
