Balcony Waterproofing Remediation – South Melbourne

We successfully managed the remediation of a failed waterproofing system across 11 private balconies in South Melbourne, including associated re-waterproofing of a lift shaft.

Our structured approach ensured correct defect diagnosis, full-slab remediation, and a compliant long-term waterproofing solution designed to prevent recurring water ingress.

This balcony waterproofing remediation project in South Melbourne, VIC involved coordinating multiple owners, staging works across occupied residences, and delivering a fully compliant waterproofing system with long-term warranties.

South Melbourne, VIC

What We Managed

We successfully managed the remediation of a common podium courtyard as well as the nearby planter boxes causing water ingress into the below carpark basement. Our structured approach ensured proper diagnosis and long-term waterproofing solutions.

The project involved coordinating multiple stakeholders while keeping the common gym operational during works, requiring careful staging and access management.

Leak Investigation

Identified the source of water ingress and developed a targeted remediation plan.

Project Coordination

Managed planning, remedial engineering design, scope of works, contractor tendering, and compliance from start to finish.

Waterproofing & Repairs

Removed large trees from planter boxes, removed old bitumen waterproofing, created proper falls, installed high-quality waterproofing to podium and planter boxes, and reinstated planter boxes with soil for landscaping.

Final Inspection

Verified waterproofing effectiveness and completed defects checks.

TitleDescription

Leak Investigation

Identified the source of water ingress and confirmed systemic waterproofing failure requiring full slab remediation.

Project Coordination

Managed remedial engineering design, scope development, contractor tendering, staging, and compliance oversight from start to finish.

Waterproofing Remediation

Used a material hoist to manage removal and installation logistics across roof and balcony levels. Demolished existing screed and failed waterproofing, reinstated screed with correct falls, and installed a compliant waterproofing system. New decking boards and dividing screens were installed to deliver a clean and consistent finish.

Final Inspection

Completed flood testing, conducted on-site inspections with engineer and supplier representatives, and secured compliance reports and 20-year waterproofing warranties.

The Challenge

The existing waterproofing system had failed across multiple balconies, creating ongoing water ingress risk for private lot owners and common property.

Committee members initially preferred isolated repairs. However, partial solutions would not have delivered long-term protection.

The lift shaft required additional coordination and compliance oversight due to its critical structural and service function.

Challenges & Solutions

Every project presents unique obstacles. Here’s how we tackled the key challenges on this remediation project.
ChallengeChallenge DescriptionOur Solution
Committee Education

Resistance to full slab remediation due to perceived cost and disruption.

Provided clear technical explanation and defect risk assessment to demonstrate why continuous slab remediation was required for long-term protection.

Occupied Residences

Works undertaken across 11 private balconies.

Carefully staged works to maintain access and minimise disruption to residents.

Systemic Waterproofing Failure

Failed screed and inadequate falls contributing to repeat water ingress.

Demolished entire system and reinstated compliant screed and waterproofing with correct falls and premium materials.

Long-Term Durability

Need to avoid repeat remediation cycles.

Installed premium waterproofing system backed by 20-year warranty and engineer sign-off.
