What to Expect During Your Building’s Concrete & Structural Repairs

Your building is undergoing concrete and structural remediation. This page covers what’s happening, how it affects your daily life, and what you need to do.

2–6 wks

Duration

Per area — depending on extent of deterioration and number of repair locations. Staged by zone so your disruption window is limited.

7am – 5pm

Working Hours

Monday to Friday. Saturdays (8am–1pm) only if required for catch-up. No work Sundays or public holidays.

Loudest period: the breakout phase.

Concrete breakout — removing spalled and damaged concrete to expose reinforcement — is the noisiest part of the project. Heavy jackhammering, grinding, and debris removal. Can run 1–3 weeks depending on extent. After breakout, noise drops significantly.

Impact on You

What changes during the works.

This is what you’ll actually notice.

🔊

Noise & Vibration

Heavy jackhammering and grinding during breakout. Vibration felt through the building structure. Significantly quieter once repairs begin.

🏗️

Scaffolding & Access

Scaffolding, swing stages, or EWPs on affected elevations. Catch nets and debris screens installed for safety. May reduce natural light.

⚠️

Exclusion Zones

Areas below repair works closed with hoarding and overhead protection. Footpaths, driveways, entries, or car spaces may be affected.

💨

Dust & Debris

Concrete breakout generates heavy dust. Dust suppression and sheeting used, but some may reach nearby windows and common areas.

👷

Workers Near Your Unit

Crews on scaffolding outside your windows, or working directly above or below your unit. Unit access may be needed for inspections.

🚗

Parking & Access

Car spaces below repair zones may be closed for safety. Driveways restricted during crane lifts. Building entry points may shift.

🐕

Pets

Keep pets away from exclusion zones and scaffolding. Falling debris and noise can distress animals. Flag dogs needing common-area access.

🔧

Services

Water or power may be briefly interrupted if services run through the repair zone. Notified in advance.

⚠ Falling Debris & Exclusion Zones

Safety zones are non-negotiable.

Concrete spalling means pieces can detach without warning. During repairs, we remove damaged material in a controlled way — but the risk of falling debris is real. Exclusion zones, overhead protection, and catch nets are installed.

Do not enter exclusion zones. These areas are barricaded for your safety. Even small pieces of falling concrete can cause serious injury. If you need access to a closed area, speak to the site supervisor — do not move barriers.

The Process

High-level overview.

The specific scope is detailed in your project’s engineering specification. This is the general sequence.

1

Investigation & Scanning

Affected areas scanned and sounded to map the full extent of deterioration — not just what’s visible. Cover meters and delamination surveys identify corroding reinforcement and compromised concrete.

2

Access & Safety Setup

Scaffolding, swing stages, or EWPs erected. Exclusion zones established with hoarding, catch nets, and overhead protection. Residents and public redirected away from drop zones.

3

Concrete Breakout

Damaged, spalled, and delaminated concrete removed by jackhammer to expose corroded reinforcement. Loudest phase. Breakout continues until sound concrete is reached — repair boundary determined by condition, not estimate.

4

Reinforcement Treatment

Exposed steel cleaned to bright metal, treated with anti-corrosion primer, supplemented or replaced where section loss has occurred. If steel isn’t properly treated, corrosion restarts behind the repair.

5

Repair & Reinstatement

Engineered repair mortar applied to reinstate the concrete profile. Larger voids may require formwork and structural grout. Repairs shaped to match original profile and left to cure.

6

Finishes

Repaired areas rendered, painted, or coated to match existing finish. In some cases a full-elevation coating is specified for uniform appearance and additional protection.

7

Handover

Scaffolding dismantled, exclusion zones removed, affected areas handed back progressively. Defects liability period begins — if anything needs attention, we come back at no additional cost.

Common Questions

What residents usually ask.

No. You stay in your unit. Main impacts are noise during breakout and temporary changes to access routes around exclusion zones.

Exclusion zones, catch nets, and overhead protection are installed before breakout begins. Stay out of barricaded areas — the controls only work if you stay behind the barriers.

We complete a dilapidation report before starting. Heavy jackhammering can cause vibration — if you notice cracking or damage, report it to the site supervisor with a photo.

Typically for the full duration on that elevation — 2–6 weeks depending on scope. Comes down once repairs and finishes are complete.

We match as closely as possible. In some cases a full-elevation coating is specified for uniform appearance across old and new surfaces.

Funded through the owners corporation — capital works fund or special levy. Individual owners aren’t separately invoiced unless private lot areas are involved.

Defects liability period plus NSW Fair Trading warranty. If something needs fixing, report it to your strata manager. We come back at no cost.
