For strata managers across NSW and QLD, few responsibilities carry higher stakes than maintaining the structural integrity of multi-unit buildings. Balconies, parapets, soffits, and façades are not just architectural features—they are critical safety assets. When concrete begins to deteriorate—through spalling, cracking, or hidden corrosion—the risks escalate quickly: falling debris, legal liability, insurance complications, and plummeting property values.

Yet many strata schemes delay action due to cost concerns, lack of technical knowledge, or the false belief that “it’s not urgent.” The truth? Proactive concrete remediation is far cheaper, safer, and more compliant than emergency intervention.

At Perfect Remediation, we work closely with strata managers, owners corporations, and building consultants to navigate this complex landscape. As a certified, in-house specialist contractor with ISO 9001, 14001, and 45001 accreditation , and part of the integrated Perfect Group , we combine engineering precision, regulatory expertise, and live-environment delivery to protect residents, assets, and reputations.

This comprehensive guide provides a practical concrete remediation checklist for strata managers, aligned with Australian standards, legal obligations, and best practices—so you can act with confidence, not confusion.

Why Concrete Remediation Is a Strata Priority

Multi-unit developments built between the 1970s and early 2000s are now entering their high-risk deterioration phase. Common issues include:

• Concrete cancer (rebar corrosion) from coastal chlorides or poor waterproofing
• Balcony spalling due to water ingress from planter boxes or failed membranes
• Parapet wall delamination from thermal cycling and inadequate cover

According to NSW Fair Trading, over 200 emergency repair orders were issued to strata schemes in 2023 alone—many involving scaffold enclosures, public footpath closures, and six-figure repair bills.

The Legal and Compliance Landscape

Strata managers operate under a clear duty of care:

NSW Strata Schemes Management Act 2015

• Requires a 10-year capital works fund plan that includes structural maintenance
• Mandates regular building condition audits

Design and Building Practitioners Act 2020

• Imposes a statutory duty of care to avoid economic loss from defective building work
• Allows owners to sue for defects—even years after construction

Work Health and Safety (WHS) Regulations

• Building owners must eliminate or minimise risks of falling objects (Regulation 78)
• Failure can result in fines up to $3M or prosecution

Ignoring visible concrete defects isn’t just risky—it’s legally indefensible.

Concrete Remediation Checklist for Strata Managers

Use this step-by-step guide to assess, plan, and execute remediation with confidence.

Step 1: Conduct Biannual Visual Inspections

Frequency: Every 6 months (more often in coastal zones)
Focus Areas:

• Balcony edges and soffits
• Parapet walls and window sills
• Planter box perimeters
• Structural columns in lobbies or car parks

Red Flags:

• Rust staining (brown streaks)
• Map cracking or surface flaking
• Hollow sounds when tapped
• Exposed rebar or rust flakes

See our guide to spotting early signs of concrete cancer .

Step 2: Commission Non-Destructive Testing (NDT)

If visual signs are present—or your building is over 15 years old—NDT is essential.

Recommended Tests:

• Half-cell potential mapping: Detects active corrosion
• Cover meter survey: Measures rebar depth vs. AS 3600 requirements
• Ultrasonic Pulse Velocity (UPV): Identifies internal delamination

At Perfect Remediation , we provide NATA-aligned NDT reports with heat maps and risk ratings—so you know exactly what needs repair, and what can wait.

In our Artarmon concrete remediation project , NDT revealed widespread delamination in a 30-year-old car park—despite minimal surface damage.

Step 3: Engage a Qualified Structural Engineer

Use NDT data to commission an independent structural engineer to:

• Assess load capacity loss
• Specify repair scope and methodology
• Provide certification post-repair

Ensure the engineer has experience in concrete remediation, not just new design.

Step 4: Select a Certified, In-House Remediation Contractor

Avoid subcontractor-dependent firms. Choose a contractor who:

• Holds ISO 9001, 14001, and 45001 certification
• Self-performs all works (no “subcontractor roulette”)
• Has proven experience in live, occupied buildings

At Perfect Remediation , we operate under government-ready systems—ensuring safety, quality, and minimal disruption.

Led by Group Safety Manager Roxanna Roszkowska and Project Engineer Lucas Rocha , our team specialises in strata-sensitive delivery.

Step 5: Review Method Statement & SWMS

Before work begins, ensure the contractor provides:

• Safe Work Method Statement (SWMS) with public safety controls
• Dust and noise mitigation plan (critical for occupied buildings)
• Debris containment strategy (e.g., netting, hoarding)
• Waste management plan aligned with sustainability goals

We recycle 60%+ of project waste—diverting concrete, steel, and packaging from landfill. Learn more about our commitment to sustainable practices .

Step 6: Verify Insurance and Licences

Confirm the contractor holds:

• Public liability insurance ($20M+)
• Workers’ compensation
• EPA and asbestos handling licences (if applicable)

All documentation is available on our licences and insurance page .

Step 7: Communicate with Owners and Residents

Transparency builds trust. Provide:

• Clear timeline and access requirements
• Contact for noise or safety concerns
• Photos of completed work

We offer resident liaison support as part of our service—minimising complaints and maximising cooperation.

Step 8: Obtain Completion Certification

Post-repair, require:

• As-built drawings
• Material compliance certificates
• Engineer’s structural certification
• 10-year warranty documentation

This supports your asset register, insurance renewals, and future sales disclosures.

Recognised as an Outstanding Employer of Choice , we ensure every project meets the highest standards.

Common Pitfalls to Avoid

Waiting for Spalling to Occur

By the time concrete falls, corrosion is advanced—and repair costs triple.

Choosing the Cheapest Quote

Low-cost contractors often cut corners on surface prep, materials, or safety—leading to rework and liability.

Ignoring Waterproofing

Balcony repairs fail within 2–3 years if membranes aren’t upgraded. Always pair structural repair with waterproofing solutions .

Skipping NDT

Guessing repair scope leads to under-budgeting and incomplete fixes.

Real-World Success: Kingsford Balcony Project

A 22-storey apartment building in Kingsford faced multiple spalling incidents. The owners corporation was overwhelmed by conflicting quotes and resident complaints.

Our approach:

1. Conducted half-cell mapping and cover meter surveys
2. Identified 14 high-risk balconies out of 88
3. Executed targeted repair with carbon fibre reinforcement
4. Upgraded waterproofing membranes
5. Completed works at night with full containment

Outcome:

• Zero resident complaints
• Full structural certification
• Capital works plan updated with 10-year maintenance schedule

Sustainability and Strata: A Shared Responsibility

At Perfect Remediation , we align every strata project with circular economy principles:

• Concrete crushed into road base
• Steel recycled through certified partners
• Low-VOC coatings to protect indoor air quality

In 2024, our industrial demolition project achieved a record-breaking recycling rate—proving that sustainability and structural integrity go hand-in-hand.

When to Seek Early Contractor Involvement (ECI)

For buildings over 20 years old, consider Early Contractor Involvement during capital planning:

• We help forecast repair costs over 10 years
• Recommend preventative measures (e.g., protective coatings)
• Align scope with budget and regulatory requirements
