Balcony Upgrade & Waterproofing Remediation in Drummoyne | Network Remedial Builders Sydney

Network, a specialist remedial builder, has been engaged to undertake significant balcony remediation and upgrade works at a three-storey residential property located in Drummoyne.

The project has been initiated due to poor original construction detailing and inadequate waterproofing design, which has resulted in the need for a full corrective remediation approach to ensure long-term performance, compliance, and durability of the building envelope.

The scope of works includes a full strip-out of the existing balcony systems back to the structural substrate. This will involve the careful removal of existing finishes and defective elements to allow for proper assessment and rectification of underlying construction issues. Once exposed, the substrate will be inspected, repaired where required, and prepared to receive a fully compliant new waterproofing system.

The upgrade works will include the installation of a modern, high-performance waterproofing system designed to meet current Australian Standards and contemporary best-practice detailing. This system will be installed in accordance with manufacturer specifications and will be subject to staged inspections and sign-off by the waterproofing manufacturer to ensure compliance and warranty eligibility. Upon completion, a 10-year waterproofing system warranty will be issued by the manufacturer.

In addition to the waterproofing upgrades, the scope includes replacement and improvement of the sliding door interfaces to ensure correct termination details, improved water tightness, and long-term durability. The existing balustrade systems will also be removed and replaced with new compliant balustrade installations, ensuring full adherence to current safety and loading requirements under applicable building codes.

Careful attention will be given to detailing at all junctions, thresholds, and interface points to ensure proper drainage, fall compliance, and elimination of potential future water ingress risks. All works will be coordinated to integrate seamlessly with the existing building structure while minimising disruption to occupants.

This project forms part of Network’s ongoing portfolio of remedial building works across Greater Sydney, where the company continues to be engaged for complex waterproofing rectification, façade upgrades, and structural remediation projects. Network maintains a strong reputation for delivering practical, compliant, and long-lasting building solutions in challenging existing building environments.

Once again, Network is proud to be recognised as a remedial builder of choice for residential and commercial projects requiring detailed investigation, technical remediation expertise, and high-quality construction delivery.
