Mitigating Moisture Risk with Smart Design and Field-Verified Systems

Waterproofing Assurance ensured compliant, durable solutions with full-scope oversight across basements, balconies, and rooftops.

Waterproofing Assurance

At 388 Lane Cove, Waterproofing Assurance was engaged to deliver a full-scope waterproofing consultancy with a core focus on compliance, durability, and performance.

Led by Director Darren Williams, the team provided early-stage input and technical oversight across all critical areas—including basements, balconies, and rooftops.

“Our role focused on compliance with Australian Standards, and specifying cost-effective, long-life materials,” Darren explained. Working collaboratively with architects and engineers,
they ensured waterproofing strategies were integrated early, eliminating common failure points and reducing long-term risk.

What made the project especially unique were the below-grade conditions. “Being mid-slope on a hill, the site presented seepage risks during the rainy season,” Darren said. “We proposed a Newton system for the basement which allowed for compliance testing and early remediation—saving time and reducing rework.”

Complex transitions, particularly around penetrations and foundation-slab junctions, posed compliance challenges. These were met with carefully developed detailing, routine site inspections, and real-time coordination with MEP and structural teams.

“We worked with the applicators on membrane preparation protocols and adapted our protection board solution to suit a last-minute change in backfill material,” Darren added.

The project exemplified best-practice in climate resilience. Systems were selected for their long-term durability under hydrostatic pressure, thermal stress, and UV exposure. Field testing—including flood tests and electronic leak detection—verified system compliance, reducing lifecycle costs and supporting warranty approvals.

By project’s end, Waterproofing Assurance had delivered a fully compliant, low-maintenance, high-performance waterproofing envelope. “We provided documentation, training and long-term maintenance guidance to the client to ensure asset performance for years to come,” said Darren.

Reliable Hydraulic Contracting for Large-Scale Projects

ASI United delivers expert hydraulic solutions for major Sydney developments, combining precision, reliability, and trusted partnerships.

ASI United

In the thriving heart of Sydney’s residential construction boom, ASI United has emerged as a trusted and highly capable hydraulic services contractor, providing sophisticated solutions to some of the city’s standout developments—including the landmark ALBA and LUNA projects.

Established just three years ago, ASI United may be young in years, but it brings decades of collective experience to the table. With its directors boasting over 30 years in the field, the company has rapidly built a strong reputation for reliable, high-quality hydraulic work across both commercial and residential sectors.

Hydraulic engineering is the backbone of modern architecture. ASI United provides commercial and residential plumbing services, investigates issues, and explains problems and solutions to ensure their clients are fully informed and satisfied.

For the ALBA and LUNA developments, ASI United was engaged to deliver complete hydraulic services, a task that required technical precision and methodical coordination. Their scope included the installation of reticulating hot, cold, warm, and non-potable water systems, as well as stormwater, sewer/sanitary, and tradewaste infrastructure—core components for two of Sydney’s newest high-end residential projects.

“On both ALBA and LUNA, we were responsible for the full hydraulic scope,” said Ben Horton, Director at ASI United. “From the early design phases through to the final install and commissioning, we worked closely with the construction teams to ensure delivery on time and to the standard expected.”

Despite the scale and complexity of both sites, the team didn’t encounter any major obstacles. “It was a smooth run,” Ben explained. “That’s a testament to our team and how we plan our work. Nothing out of the ordinary came up—which is exactly how you want a job of this size to go.”

With a team of 50 employees, ASI United is structured to handle large-scale projects without compromising agility. “We had around 25 people dedicated to these developments,” Ben said. “That includes tradespeople, apprentices, and project supervisors. Every one of them understands the importance of doing the job once—and doing it right.”

Located in Clyde, NSW, ASI United prides itself on professionalism and partnership. Their collaborative approach with builders and developers ensures seamless integration of hydraulic systems—often one of the most complex layers in a build.

While ALBA and LUNA stand as recent highlights, they are far from the only projects in ASI United’s pipeline. “We’re currently working on another four sites of similar size and nature,” Ben revealed. “We’ve hit our stride, and we’re excited about the scale and diversity of work coming through.”

These projects continue to solidify ASI’s reputation as a go-to partner for hydraulic contracting across Sydney’s evolving urban landscape.

As the city continues to expand upwards and outwards, the demand for reliable hydraulic contractors is only set to grow—and ASI United is ready to meet it.

“We’re focused on steady growth,” Ben said. “Not just in terms of projects, but in nurturing our people and refining our processes. That’s what keeps quality high and clients happy.”

From expertly planned systems to faultless delivery, ASI United continues to prove why they’re one of the most dependable hydraulic contractors in the game.

Stone Will Landscaping has once again raised the bar in luxury landscape construction with their stunning work at the prestigious Rumbalara Residences. Responsible for the entire outdoor transformation, the team brought to life a seamless integration of natural beauty, high-end materials, and practical innovation across the multi-residential development.

“Our scope included everything from softscaping and hardscaping to premium turfing, custom sports surfaces, and bespoke planters,” said David Black, Director of Stone Will. “Every outdoor space—communal gardens, terraces, pathways—was designed to reflect the same level of sophistication as the interiors.”

In line with the project’s vision of creating a tranquil retreat, Stone Will worked in close collaboration with architects and developers to hand-select climate-resilient, native plant species and elegant finishes that harmonised with the natural surroundings. “We paid attention to every detail—from textures and colours to materials—ensuring that the landscaping complemented the architectural vision,” David added.

To overcome these, the team employed advanced erosion control methods, precision terracing, and a well-coordinated logistics strategy to ensure efficient and safe material delivery and installation.

Sustainability was another cornerstone of the project. “We incorporated drought-tolerant plants, water-efficient irrigation systems, and used locally sourced materials,” said David. “This not only reduced the environmental impact but also ensures a low-maintenance, thriving landscape long term.”

The Rumbalara Residences project is a showcase of Stone Will Landscaping’s signature approach—precision, collaboration, and innovation. With an unwavering commitment to excellence and sustainability, the team has delivered an outdoor environment that’s as functional as it is breathtaking, elevating luxury living in one of Australia’s most picturesque locations.

Fire Protection Systems for Multi-Tower Residential Development in Gosford

Goldfish & Bay delivered compliant fire protection design for Rumbalara’s multi-building residential development, addressing project complexity through coordinated engineering solutions.

Goldfish and Bay

Goldfish and Bay, a leading building services design and consulting firm, delivered specialised fire protection solutions for the Rumbalara Residences project in Gosford.

With a strong focus on quality, compliance, and technical performance, the team designed a system that integrated effectively into the development’s large-scale infrastructure.

Rumbalara comprises four interconnected residential towers, each up to 11 storeys, supported by a 11,000m² basement structure. The scale and complexity of the development required a carefully coordinated fire services strategy to ensure safety, resilience, and long-term reliability.

Goldfish and Bay’s Fire Engineering team designed and implemented a combined hydrant and sprinkler system, providing both fire suppression and firefighting water supply through a single integrated network.

The system was developed to meet AS 2118.6-2012 and incorporates key redundancies, including dual diesel-driven fire pumps. Each pump is capable of meeting pressure and flow requirements independently, with automatic switchover to maintain system continuity in the event of failure.

Water supply reliability was further supported through a primary on-site storage tank and a secondary mains connection.

A looped pipework configuration ensures consistent water availability, while sectional isolation valves enable targeted maintenance without compromising building-wide protection.

Throughout the design process, the team prioritised hydraulic performance, pressure zoning, and full compliance with relevant standards. Given the scale and complexity of the Rumbalara development, a compliant and resilient fire protection system was essential.

The integrated design addressed both fire suppression and operational continuity and was developed in close coordination with Deicorp and other key project stakeholders to ensure alignment with performance requirements and regulatory standards.

The integration of these features reflects Goldfish and Bay’s broader capability in delivering reliable, high-performing fire services for large-scale residential projects.

Goldfish and Bay holds ISO 9001, ISO 14001, and ISO 45001 certifications and maintains a 4-star iCIRT rating, underscoring its commitment to quality, safety, and compliance. The firm is also registered with Engineers Australia, FPA Australia, AIRAH, and the Hydraulic Consultants Association of Australasia (HCAA).

Goldfish and Bay’s broader project portfolio with Deicorp includes Tallawong Village, Melrose Park, The Rothschild, Marquet & Mary, Hyde Metropolitan, 130 Joyton Avenue, Highline Westmead, and Kings Bay Precinct, reinforcing the firm’s position in delivering dependable fire and building services across complex, large-scale developments.
