To consistently deliver expert waterproofing solutions, the Danrae Group team relies on decades of experience and a thorough knowledge of waterproofing Australian standards.
Australian standards set out specifications and design procedures to ensure businesses deliver safe, effective and reliable products and services. There are two types of standards – mandatory and voluntary.
Voluntary standards are developed by non-government bodies such as Standards Australia and the international body ISO (International Organization for Standardization) and represent best practice.
Mandatory standards are law, and all service providers must comply with them. They are developed by the Australian Competition and Consumer Commission (ACCC) and consist of safety standards (including performance, design and construction) and information standards.
The Australian Standards applicable to waterproofing are:
There is no standard for below ground waterproofing.
The standards above cover materials, solution design and membrane installation, and it is essential that waterproofing contractors follow every applicable standard to deliver a consistent, reliable and permanent waterproofing solution.
We have, of course, reported several times on waterproofing failures across strata properties in particular and new government legislation to tighten up industry standards. Commercial waterproofing statistics consistently indicate that damage from ineffective and neglected waterproofing is the primary culprit of defects.
According to the standard, the primary causes of waterproofing defects are:
It is vital therefore that in addition to adhering to the standards, contractors also have a thorough and detailed understanding of them in order to avoid future waterproofing failure.
One issue that often impacts the delivery of a quality, compliant waterproofing repair or installation is misinterpretation of clauses in the standards. The following terms for instance are often misunderstood:
1.4.24 Waterproof (WP) – The property of the material does NOT allow moisture to penetrate.
1.4.25 Waterproofing System – It is the COMBINATION of elements to provide a waterproof barrier.
1.4.26 Water resistant (WR) – The property of a system that restricts water movement; will not degrade under conditions of moisture (MAY NOT BE WATERPROOF).
1.4.29 Wicking – The action of water rising by a capillary path.
We’re able to deliver, thanks to a thorough knowledge of waterproofing Australian standards and the expertise to provide tailored, safe and compliant waterproofing solutions. With an in-house team of waterproofers and trades professionals, we can also oversee every stage of a project to guarantee our quality.
