Welcome to the Danrae Group. We are the experts in waterproofing, remediation and commercial.
For over 20 years we have been providing exceptional waterproofing and remedial building services… and we have grown to become the in-demand go-to for clients across the country who need waterproofing advice, design and remediation quickly, efficiently and expertly.
We’re not afraid to admit that we’re one of the few in this industry that truly excels at end-to-end waterproofing management.
We don’t believe in shortcuts or half-measures. Every project is approached with care, attention to detail, and a commitment to quality from start to finish. We take pride in delivering work that lasts, with no loose ends and no compromises.
We challenge the status quo and look for smarter ways to work. By thinking differently, reducing waste, and analysing the root cause of problems, we deliver solutions that are more cost-effective, efficient, and durable. Continuous improvement is part of how we operate every day.
We take ownership of our work and our decisions. When challenges arise, we have honest conversations, take responsibility, and focus on solutions rather than blame. Transparency and accountability build trust — with our team and our clients.
Our people are our greatest strength. We value diversity, collaboration, and open communication, where every team member’s voice matters. We work together with respect and integrity, and we don’t engage in behind-the-scenes or “triangle” conversations — we address things directly and constructively.
We believe growth comes from curiosity and experience. We encourage our team to learn from mistakes, develop new skills, and continuously improve. Knowledge is shared, not isolated. When one person learns, the whole team benefits.
We treat our people, customers, and suppliers like family. That means respect, loyalty, and long-term relationships built on trust. We care about the outcomes we deliver and the people we work with, creating partnerships that go beyond a single project.
It’s true. And it’s why our advice is highly sought after at the highest levels – from consulting on commercial new builds, to the entire scope of remedial building.
We have the depth of knowledge to find the right solution for complex issues across the commercial, construction, commercial and strata sectors. And we stay abreast of building reforms and industry changes so that every solution meets the highest standards.
Because we understand that your time is precious and quality is key, we guarantee to complete each project to exacting standards, on time … every time.
Some customers come to us with a building leak – and need it fixed fast. Some may require investigative advice for an ongoing issue. And others have a precise demand for a complex project.
Our team is the best in the business and includes carpenters, builders, roofers and electricians. In short, we have full capability in end-to-end waterproofing and remedial building projects.
We’ve worked on ventures of every shape and scale – from residential homes to major infrastructure. We have extensive experience with concrete cancer and spalling.
With our decades of experience, we’re adept at diagnosis, design, waterproofing and remediation – plus full project management. We also provide ongoing preventative maintenance where required.
Our clients include a wide cross-section of the strata, commercial, government and health sectors. They include leading Australian property developers like JLL, Goodman and Frasers Property.
And we’ve project managed waterproofing for everything from schools to hospitals to high-rise apartments.
Some of our major projects include IKEA Tempe, ANSTO (Australia’s Nuclear Science and Technology Organisation), The Kinghorn Cancer Centre and Campbelltown, Camden and St Vincent’s Hospitals.
And as diverse as client projects may be, they have one thing in common.
They need guaranteed fast-response and comprehensive waterproofing, intrusive investigation and remediation – from a trusted professional.
Our waterproofers are trained and certified in every waterproofing technique — and we offer the all-round service that comes with decades of successful project completion.
Founded by Ron and Lillian Caruana in 1996, the Danrae name was inspired by their children, Daniel and Renee.
As the business has grown, they’ve come on board – bringing their own unique skills and expertise learned from growing up in the business.
The Danrae Group has decades of combined experience.
Our diverse team of carpenters, builders, plumbers and skilled project managers brings a wealth of experience, energy and dedication.
Our loyal team members are proud to be part of Danrae – and we’re super proud of our team and our ability to deliver exceptional services to our clients.
We’ll be on hand for every stage of every project – so your waterproofing solution is seamless. And that means guaranteed waterproofing solutions on time, every time.
Expertise and efficiency are the Danrae Group hallmarks. We deliver quality solutions… with no shortcuts. It’s just one way we provide full client satisfaction.
As part of our commitment to superior service, we also use only premier brands of waterproofing products including Sika, Parchem and Fatra.
We’re fully trained and experienced in all industry-leading brands, so we are exceptionally qualified to deliver the highest quality waterproofing and remediation solutions.
Danrae Group has grown to service some of the leading names in construction and building management, but we’ve retained a family-focused attitude.
We understand that everyone brings something to the table – and we value every contribution.
And that’s why we’re also committed to nurturing our employees and helping every team member develop their career. When our team delivers, we deliver.
If you’re interested in building a career with Danrae, we’d love to hear from you. And we’d love you to take a look at everything we offer our valued team members.
We believe strong values build strong communities. Danrae Group embeds sustainability, ethics, and environmental care into everything we do. Our responsibility goes beyond buildings; it extends to responsible resource use, waste reduction, and creating safer working environments for our people and partners.
Our approach includes:
We actively support the local communities who support us. From charitable collaborations to skills development and sponsorships, we invest in initiatives that uplift people and create opportunities.
