Professional Concrete Repair Sydney
Cracked driveways, spalling garage floors, sinking paths, pitted patios — concrete damage doesn't mean you need replacement. Wizcrete has been repairing Sydney concrete since 2005, using premium polymer-based repair systems that bond permanently.
Common Concrete Problems We Fix
- Cracks & Fractures — Hairline to structural. Injected, stitched, or patched depending on severity
- Spalling & Flaking — Surface peeling caused by poor curing or salt damage. Ground back and resurfaced
- Pitting & Pop-outs — Small holes where aggregate has come loose. Filled and colour-matched
- Sinking & Uneven Slabs — Settlement due to soil movement. Mudjacking or slab lifting available
- Expansion Joint Damage — Worn or broken joints. Re-cut, cleaned, and sealed with flexible filler
- Old Stencil / Paint Removal — Stripping old coatings back to bare concrete for a fresh start
Our Repair Process
- Diagnosis — We identify the root cause (not just the symptom)
- Preparation — Grind, cut out, or pressure clean the damaged area
- Repair — Apply polymer-modified repair mortar or resurfacer
- Finish — Colour-match, texture-match, and seal to blend with surrounding concrete
