At Danrae Group, we pride ourselves on our comprehensive waterproofing solutions for strata, construction, civil, commercial and government sectors.

We’re committed to excellence for every customer – and we lead by example to ensure the highest quality standards across the waterproofing industry.

We’re pleased to announce that we are now offering waterproofing consultancy services. Our expert waterproofing consultant will provide an independent assessment of your contractor’s waterproofing at every stage of a new construction project – to ensure it consistently meets Australian Standards.

We’ve recently been providing consultant services for the boutique Opera Residences development at Bennelong Point. Here’s how our expertise is helping this landmark strata project take shape.

Expertise for a landmark project


Opera Residences is a $600 million luxury apartment development on Sydney Harbour, in close vicinity to the Opera House. Once complete, it will feature 104 high-end apartments over 19 levels, a restaurant, swimming pool, gym, retail outlets and a six-level car park.

Opera Residences is the joint creation of developers Macrolink and Landream, architects Tzannes and Crone Partners, and Make interior designers.

At an early stage of the development, the clients called on Danrae Group Founder Ron Caruana. Ron has decades of experience across all aspects of waterproofing, including diagnostic, solution design, remediation and preventative maintenance. In addition to founding Danrae Group, he is the NSW representative of the Australian Institute of Waterproofing.

He was the ideal choice to ensure the project’s waterproofing meets the same exceptional standards as every other aspect of the development.

Ensuring exceptional quality


As part of our waterproofing consultancy, we provide comprehensive assessment, testing and reporting of internal and external waterproofing at multiple stages of construction to ensure your waterproofer has designed and installed it to the highest quality – and that it is fully compliant. Ron explains the process as delivered for Opera Residences:

“The developer engaged me to oversee the installation around a year ago. I reviewed all the design documents, including product data sheets, to confirm both the design and materials – glues and membranes – met Australian Standards.

Additionally, I have provided visual inspections and random testing through the project duration on balconies, bathrooms, the swimming pool and the roof,” adds Ron. “We also use specialised technology to confirm the membrane micron sizing is correct. The builder completes inspection test reports and I also double check their reports are accurate and completed as required.”

Improving industry standards


Ron believes the call for independent expert waterproofing consultants reflects the drive for enhanced industry standards. As we reported last year, the NSW government has introduced new legislation to overhaul the building and construction industry across the state.

As part of the new RAB Act, one of two key pieces of legislation introduced, all building work must comply with Building Code of Australia (BCA) requirements before an occupation certificate (OC) can be issued.

The NSW Building Commissioner has broad powers to advise against OCs if there is evidence of any defects. Without an OC, developments will not be able to proceed.

Developers are seeking independent and specialist advice to ensure every project meets stringent standards. “There are many building consultants around but not specialist waterproofing consultants. It’s imperative to understand the logistics of waterproofing and have a thorough knowledge of Australian Standards for waterproofing,” adds Ron.
