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.
