Remedial works in the Sydney metropolitan area
Engineer-directed concrete repairs, membrane renewals and leak investigations for strata, commercial and industrial envelopes.
Why Sydney buildings need disciplined remedial work
Coastal weather, thermal movement and ageing membranes push balconies, podiums and basements past their original design life. Our remedial division works from Bankstown across the Sydney metro, pairing licensed builders with specialist subcontractors so every cut-back, patch and coating is photographed and labelled for your consultant.
Whether you are reacting to a waterproofing failure or staging a ten-year capital works plan, we translate engineer drawings into ITPs, isolate work zones for residents and remove waste through approved lift windows. That keeps defects from reopening after the first storm.
What is involved
- Moisture mapping, hammer sounding and pull-off tests arranged with your nominated engineer.
- Concrete breakout, reinforcement treatment and cathodic options where specified.
- Sheet, liquid or torch-on membranes reinstated to manufacturer details and flood tested.
- Expansion joints, flashings and drainage rebalanced before final tiling or traffic coatings.
What to expect on site
7.00am toolbox talks cover noise limits, fire panel isolations and dust control. You receive daily photo logs, SDS registers and inspection hold points before membranes are covered. Variations only proceed once you approve costs in writing, which protects strata committees from open-ended hourly rates.
Three reasons owners specify Velocity CG
- Traceability: Batch numbers, curing times and weather readings travel with your handover USB.
- Strata-aware programming: We stage works per level so only one fire zone is offline at a time.
- Local supply chain: Materials are sourced through NSW distributors to shorten lead times.
Frequently asked questions
Do remedial works require a certifier in NSW?
Most balcony and façade repairs trigger either a complying development pathway or a full development application depending on extent. We prepare inspection-ready packs so your certifier can verify structural and waterproofing elements against the National Construction Code and referenced Australian Standards.
How long should waterproofing cure before flood testing?
Cure times vary by polymer chemistry and ambient humidity. We follow manufacturer data sheets, typically 24-72 hours, and only flood test once the engineer signs off on preparation. Rushing this step is the main reason leaks return within a year.
Can residents stay in the building during works?
Yes, provided egress and fire systems remain compliant. We coordinate isolations with your building manager, install temporary barriers to Australian Standards for fall protection and schedule noisy plant inside by-law hours across Sydney strata schemes.
