UV Accelerated Weathering Test: Features, Diagram, Uses, and Standards
This involves careful design to minimise the risk of water ingress and redirecting it away from the building to prevent damage to nearby properties. By meticulously preparing substrates, selecting compatible materials, designing effective drainage, and carefully addressing membrane terminations and penetrations, the risk of water ingress can be minimised. The final layer of an external waterproofing system often involves the application of overlays or finishes. To maximise the durability and effectiveness of external waterproofing systems, incorporating protective measures and finishes is essential. These terminations must be designed and executed meticulously to ensure that water does not bypass the waterproof barrier at edges, corners, and transitions. The correct termination of waterproofing membranes is crucial for the overall effectiveness of the waterproofing system.
Membrane Terminations: Essential for Preventing Water Ingress
There are 5 main types of waterproofing membranes that are differentiated by the way they are attached to the substrate and held in position; ballasted, fully bonded, inverted roofs, mechanically fastened & partially bonded. Independent Testing Australia (ITA) is equipped with specialised apparatus to test materials and provide data to coating manufacturers, specifiers, builders and waterproofers to determine product suitability for use in the Australian construction industry and satisfy documentation requirements of the Australian Building Code (BCA), the National Construction Code (NCC) and Australian Paint Approval Scheme specifications (APAS). As such, specific consideration should be given to the curing of a membrane, in relation to both the product type as well as the area of application. The same membrane installed to both internal and external areas, may have a vastly different curing time in each area, depending on variables such as temperature, relative humidity, and airflow. Inherently the ambient conditions for internal areas and external areas are likely to differ, and this is likely to have a significant impact on the curing of a membrane system.
Ensuring Effective Waterproofing Through Design and Application
By adhering to these standards, professionals ensure that buildings are adequately protected against water ingress, thereby preserving structural integrity and preventing moisture-related damage. It is essential to carefully consider each area of a building’s integral requirements when selecting a high-quality waterproofing membrane to ensure long-lasting protection against water ingress. In order to maintain healthy living conditions and to preserve the integrity of a building and its property, it is crucial to avoid the accumulation of water in internal wet areas. These standards are designed to guide contractors, builders, and engineers in the selection of materials and the installation of waterproofing systems for external above-ground use, such as balconies, decks, and roof

In any case, at least one of Appendix A, C or D should be used for all external pedestrian surfaces and internal surfaces that have a reasonably foreseeable risk of the presence of wet substances such as water, grease and oi
Accreditation with the National Association of Testing Authorities
The wet pendulum and dry floor friction test methods (Appendices A and B) may not apply to heavily profiled surfaces. Our technicians are highly trained and utilise the latest technology available including wet pendulum tests to ensure our clients have peace of mind Regular monitoring involves slip resistance testing with either or both methods in AS/NZ 4663. Continuous monitoring of your pedestrian surface through regular testing will ensure the risk of slipping remains known and a responsible risk management plan is maintaine
Effective water management is a critical component of external waterproofing, necessitating the implementation of proper falls and drainage to guide water away from the structure. Our approach combines in-depth industry knowledge with rigorous adherence to these standards, ensuring that every waterproofing system we design offers superior protection against water damage. The standard helps builders and contractors specify materials that are not only waterproof but also resistant to UV radiation, temperature variations, and physical damage. The secret is the control of the membrane application from the supplier to the contractor as well as the onsite support and quality control of the installation. During this time, we have noticed that the main causes of waterproofing failure is in the design, application, incorrect membrane and installation. Projex Group Pty Ltd has been supplying the Australian market with waterproofing systems for over 30 year
