We go above and beyond for every customer. We tailor the best quality waterproofing plan, we’re qualified to install every type of membrane and we provide comprehensive project management that includes full building remediation.
We also never say no to a challenge. It’s why our waterproofing project solutions have incorporated everything from 130 tonne cranes to professional abseilers.
Ron Caruana, Danrae Group Co-Founder and our lead Project Manager, ensures we deliver every project seamlessly.
While we manage every stage of diagnosis, design, repair and rebuild with our in-house team, there are just a few things beyond our reach… as seen in our waterproofing for a Wentworth Street penthouse apartment in Surry Hills.
“We had to engage abseilers for a concrete cancer repair on the facade,” explains Ron. “We do it quite regularly. We instruct them step by step and they carry out the process, working 10 storeys high.” The extensive preparations included installing barricades on the rooftop, organising the closure of one section of road and lifting the materials to the roof – by hand.
“We couldn’t use a crane, given the particular location, so our team had to bring the material up via the lift… and stairs. When you consider that the membrane rolls are close to 100kg, it’s very exhausting.”
Close by to Wentworth Street is Lacey on Cooper, an apartment block that had been plagued by leaks and waterproofing issues for years. Zach Smith, our specialist torch-on waterproofer, worked on the roof and beneath a rooftop swimming pool to provide a first-class membrane installation.
Ron explains that a lot of effort also went into logistics. “Being 16 storeys high, we had to crane up all the materials,” he explains.
“We also had to coordinate the crane hire and street blockage with deliveries of pavers from Melbourne, the arrival of the carpenters with their decking and the carpet guys bringing in the artificial turf for the tennis court. And we had ten cubic metres of rubbish that had to be removed from the roof.” And that all had to happen in one day.
It’s this attention to detail and expert processes that help us deliver projects on time and with quality guaranteed.
Central to quality strata waterproofing like Wentworth Street and Lacey on Cooper is our top-notch diagnostic team. They have years of experience targeting the root cause of issues, including concrete cancer, liquid damp coursing, leaks, cracks and efflorescence.
To ensure our diagnostic is 100% accurate, we employ advanced technology and multiple methods, including traditional water testing, Electric Field Vector Mapping (EFVM) and InfraRed Detection.
InfraRed or thermal imagery works by identifying heat differences, and for our purposes, those areas affected by moisture. We use highly accurate InfraRed detection to pinpoint precise locations of water ingress.
It’s a process made easier with drone technology. Our ground team controls each drone which sends a live feed during operation. Drones can help us assess expansive flat roofs and high-rise facades, quickly and very thoroughly.
Having worked on so many projects, our team understands safety and compliance inside and out, knowledge we called on for our St Vincent’s Hospital waterproofing repair.
Staff had discovered water seeping in over the MRI theatre, which is home to highly sensitive, specialised and expensive technology. “It’s a critical area,” says Ron. “We had to fix the issue with minimal impact on patients and staff and fix it as fast as possible to protect the equipment. We also had to consider noise, given it’s a public space and there are offices nearby.”
So, to make sure every waterproofing project is sound, we triple test our quality.
On completion of every installation, Danrae conduct their own ITP (Inspection Test Plan) process along with an EFVM test which is conducted independently prior to the relevant supplier certifying each individual job if required.
As Ron explains, “We give the client the reassurance of having both internal and external testing… and with additional supplier sign off, we can issue our full warranty.”
