Water leakage below door openings has been a source of concern for the Queensland Building and Construction Commission (QBCC) and other state regulators for a number of years.
The Building Code of Australia’s adoption of ‘AS4654 Waterproofing membranes for external above-ground use – Part 1 Materials and Part 2 Design and installation’ means that building contractors working throughout Australia are provided with clear and consistent detailing requirements to eliminate water leakage in construction. This standard came into effect in Queensland back in May, 2013.
Tradespeople working in Queensland are used to the heat, although there are a few more things they need to be aware of while on worksites as summer temperatures start to rise.
High temperatures (above 30 degrees Celsius) and windy conditions can affect the application and performance of various building materials, such as concrete, primer, rendered coating, waterproofing membrane, adhesive, and grout.
