Under the QBCC Act 1991, waterproofing work must be carried out by contractors licensed with the Queensland Building and Construction Commission (QBCC). All contractors in our network hold current QBCC licences and appropriate insurance. Request your free quotes to get matched with licensed professionals.

Brisbane's subtropical climate can affect curing times — high humidity may extend drying periods slightly. Our matched contractors will provide accurate timelines in their free quotes.

AS 3740 is the Australian Standard for waterproofing of domestic wet areas. It specifies minimum membrane requirements, bond-breaker placement, and testing protocols.
