Remedial works in the Sydney metropolitan area
Engineer-directed concrete repairs, membrane renewals and leak investigations for strata, commercial and industrial envelopes.
Why owners corporations choose Velocity CG for remedial work
Engineer-backed scopes, documented installations and programming that respects residents.
Documented handover packs
Batch numbers, curing times and weather readings travel with your handover pack when your scope calls for them.
Level-by-level staging
We stage works per level so only one fire zone is offline at a time, where your engineer and building rules allow it.
Australian supply partners
Membranes, coatings and systems are sourced through Australian distributors and selected to align with Australian Standards as set out in your engineer’s scope.

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 across the Sydney metro from our Sutherland office, 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.

What is involved on site
- 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.
Toolbox talks may occur before higher-risk activities and cover noise limits, fire panel isolations and dust control. You receive photo logs, SDS registers and inspection hold points before membranes are covered.

Strata and commercial feedback from waterproofing and envelope projects.
“They flood-tested before tiling went back down and sent us the curing log. The engineer signed off without a single rework item.”
Strata manager, Eastern Suburbs
“Our balcony membrane failed twice with another contractor. Velocity mapped moisture, stripped to slab and reinstated per the data sheet. Two seasons on, still dry.”
Chairperson, owners corporation
“Daily photos went straight into our defect portal. When the certifier asked for proof of membrane thickness, we already had it.”

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.
