Services
Two service streams, one accountable crew
Pick the one that sounds like your job. Both are delivered by the same directly employed crew, under the same insurance and with the same photographed close-out.
I manufacture or install precast panels

I have a concrete problem on a building
- Concrete cancer, spalling and exposed reo treated behind the bar, not patched over.
- Crack repair, honeycomb repair, correction of falls, floor grinding and levelling.
- Commercial, industrial and infrastructure buildings direct, and strata buildings as the concrete subcontractor to remedial builders, across Sydney, with AU$20,000,000 public liability.
Precast panel post-works
The finishing works between panel installation and practical completion
Works during and after the panel installation process, delivered to the manufacturer's specification and application requirements.
We understand that post-installation works sit on the critical path. Our commitment is a planned sequence, agreed with the builder and our supervisor at least one day ahead, so the trade behind us is never waiting.
Scope
- Caulking & joint sealing, internal and external
- Base grouting
- Dowel grouting & liquid grouting
- Patching of lifting plates & grout tubes
- Expansion joints
- Fire-rated joint systems
- Panel-to-panel and panel-to-blockwork junctions
- Defect rectification & punch-list close-out
Junctions and substrates
Silicone joint sealing to the system nominated by the panel supplier or builder. Sealed to precast, blockwork, brickwork, render, cladding and tiles. Expansion joints and fire-rated joint systems installed as a system, not as a bead.
Who supplies what on site

Concrete care & repair

What we treat
- Concrete cancer & spalling treatmentRust staining, cover lifting off in plates, and concrete that sounds drummy or hollow when tapped.
- Exposed reinforcement treatment & reinstatementBar visible at the surface, from low cover, vibration faults or corrosion.
- Honeycomb & general patchingVoids and open aggregate where the concrete did not compact around the reinforcement.
- Crack repairCracks in slabs, walls, parapets and soffits, repaired and made good to the surrounding surface.
- Technical demolitionControlled break-out of concrete sections, with the surrounding structure left intact.
- Floor grinding & floor toppingWorn, uneven or damaged slabs brought back to a level, usable surface. Concrete floor levelling to the tolerance specified.
- Correction of fallsPonding on balconies, car park decks and wet areas that should drain and do not.
- All grades of finishing productFinished to the surface class the specification calls up, ready for coating or left as the final face.

How a repair is done
01
Break out to sound concrete
Concrete is broken out square and cut back behind the bar, so the full circumference of the reinforcement is exposed rather than the face of it.

02
Reinforcement cleaned and treated
Steel is cleaned to bare metal and coated with a zinc-rich primer before the section is reinstated.

03
Reinstated to the original line
Repair mortar applied to the manufacturer's specification and ruled back to the original profile.

04
Finished to the class nominated
Surface finished to the class the specification calls up, ready for coating.

Why the repair holds
A patch applied over corroded steel hides the defect for a season and comes back larger. Cutting back behind the bar costs more time at break-out, and it is the difference between a repair and a cover-up.
Where the cause is cover depth or water ingress rather than the patch itself, we put that in writing before starting, so the builder can decide the scope with the engineer.
The same wall, start to finish
One parapet run, photographed from the same position at each stage. The pockets below held corroded cast-in fixings. The same face is shown as found, prepared, reinstated and finished.






Overhead slab repair
Soffit repairs are saw-cut to a square perimeter, broken out to sound concrete, and reinstated in halves so the bay stays supported while it cures.


Two or three photos with something in frame for scale, plus the building type, is enough to start.

- Project price

On site
We bring
Platform ladders and steps. Hand, battery and electric tools. Gloves, safety glasses, hard hats and boots for every worker. Height safety equipment where required.
You provide
Scissor and boom lifts. Site induction. A panel installation schedule, or the defect list and access arrangements for remedial work.

Our crew
Directly employed. Uniformed. Inducted.
The people who start your package are the people who finish it.
Our General Manager, Bruno Wagner, has more than ten years in the precast and concrete industry in Australia: caulking and patching precast panels on the tools, then concrete remediation, before running the crew and the programme. The method on site is one he has done himself.
Every crew member is directly engaged by Black Feather, uniformed and inducted on the head contractor's site before start. We pay above the going rate for the trade, and that is a retention decision rather than a gesture: a crew that stays is a crew that knows your sequence, holds the programme and leaves less rework for the trade behind us. It is what allows us to hold quality on repeat engagements rather than staffing a job and disappearing.
On-site practice
- Gloves, safety glasses, hard hats and boots supplied to every worker
- Fortnightly toolbox talks raising current site safety points
- Silica Awareness training and mask fit test completed by every worker
- Height safety equipment and harness use where required
- Task sequence agreed with builder and supervisor one day prior to start
- Compliance with head contractor site rules and inductions

Straight answers
Straight answers
The five things we hear before a first engagement, and where we stand on each.
“You'll staff the job and then disappear halfway through.”
Our crew is directly employed, not hired in for the job, so the people who start your package are the people who finish it. The sequence is agreed with your supervisor at least one day ahead, and if a date has to move you hear it from us before it moves, not after. Every rectification is photographed, so the close-out is documented rather than verbal.
“A new supplier means three weeks of compliance paperwork.”
The documents a prequalification asks for exist today: certificates of currency for AU$20,000,000 public and products liability and for workers compensation, White Card records for every worker, ABN, ACN and GST registration. Request them at tender stage and they are issued to you or loaded straight into your portal. The Capability Statement on this page is the same information in the format your estimator files.
“Your rate won't fit the way my contract is written.”
Then tell us how it is written. We quote by project or by hour, built from your scope, the drawings or the defect list, and with or without material, so the price lands in the format your contract already uses. The engagement fits your contract, not ours.
“You'll patch over it and it comes back in two years.”
A patch applied over corroded steel hides the defect for a season and comes back larger. We break out behind the bar, clean the reinforcement to bare metal, prime it, and only then reinstate. Where the cause is cover depth or water ingress rather than the patch itself, we put that in writing before starting, so you can decide the scope with your engineer instead of paying for the same repair twice.
“You're too big for my building. Or too small for my job.”
The crew that seals the joints on a full data centre package is the same crew that reconstructs a single stair haunch. What changes is the sequence and how many people we put on it, not the method or the paperwork. Tell us the extent and we will say plainly whether it is a job for us.
