Structural scope
Facade & external wall repair
Facade concrete cancer risks something balconies rarely do: fragments falling to streets and walkways. Window heads, sun hoods, awning edges and slab bands carry lightly covered steel in fully exposed positions, and their failures shed material from height. Remediation pairs the corrosion repair itself with honest access engineering and public protection.
Scope
What this covers
Make-safe surveys and removal of loose material as an immediate first stage
Systematic breakout and reinstatement of affected bands, heads and hoods
Crack injection where structural cracking admits water to the steel
Colour and texture matched finishes on architectural concrete
Overhead protection, exclusion zones and traffic management during works
Timing
When it's needed
Cracked or bulging render lines tracking reinforcement, rust bleeding through paint, fragments found at ground level, or defects noted in facade safety inspections. Buildings above busy footpaths carry an obvious duty here, a make-safe stage can proceed quickly while the full program is designed.
Concrete dropping from a building is an emergency, not a maintenance item. Cordon off the area beneath any loose or drummy overhead concrete, keep residents and the public clear, and arrange a make-safe inspection immediately: especially for awnings, window hoods and balcony edges above walkways.
Quote variables
What shapes the scope
Height and access strategy, often the largest single cost driver
Extent of concealed deterioration behind render and paint systems
Heritage or architectural finish requirements on visible elements
Staging to keep entries, footpaths and tenancies operating beneath the work
Concrete remediation on NSW strata and commercial buildings sits within the state's building and design accountability framework: structural repair work should be specified or reviewed by a registered structural engineer, performed by contractors licensed for the work, and documented so the owners corporation holds a proper record. Ask for licence details, engineer registration and product system warranties in writing.
