Concrete Restoration Case Study for a Heritage Strathfield Property
A 1940s Strathfield property had extensively cracked and damaged garage concrete with multiple structural cracks, surface spalling, and previous DIY repair attempts that had failed. We injected structural cracks, levelled spalled areas, ground away failed DIY patches, and sealed the natural concrete without hiding the original surface.
Service benefits
- Location: Strathfield, Inner West
- Surface and system: Concrete; Not applicable — restored and sealed natural concrete
- Preparation: Epoxy crack injection, spall levelling, diamond grinding and penetrating sealer
- Result: Restored concrete that looks and performs far better than expected. Cracks are fully injected, surface is smooth and sealed, and the natural concrete appearance is preserved in keeping with the heritage property.
- Timeframe: 2 working days
- Sweep regularly to prevent grit accumulation
- Reapply penetrating sealer every 3-5 years
Pricing and project context
This 35–55 sqm concrete restoration and crack repair project shows how preparation, repairs, selected finish, access, and handover timing shape a written scope. Grinding and repair sequencing allowed the slab to be stabilised while preserving the appearance expected for a heritage-sensitive property.
FAQs
Can cracked concrete be repaired without replacement?
In many cases, yes. We use epoxy injection, routing and sealing, and resurfacing techniques to repair cracked concrete.
What causes concrete to spall?
Spalling is usually caused by moisture penetration, freeze-thaw cycles, poor finishing, or corrosion of reinforcing steel.
Can cracked concrete be restored before epoxy?
Yes. Surface Master Australia repairs concrete cracks using epoxy crack injection for structural cracks and semi-flexible polyurethane for movement joints. Spalls and surface defects are filled with rapid-cure repair mortars. Restoration work cures before grinding and coating proceed.
