Woronora Heights sits on the plateau above the Woronora valley, a tidy pocket of estate housing mostly built from the 1980s onward. The streets are level by Shire standards, but the ground has its own personality. Much of the plateau carries clay soils, and clay moves. It swells when wet and shrinks when dry, and concrete that was not built for that cycle shows it in cracks within a few years.
We are a referral service, not a concreting company. We connect Woronora Heights homeowners with experienced, insured local concreters who know how to build on reactive ground.
Common concreting jobs in Woronora Heights
- Driveway replacements where clay movement has cracked the original
- New slabs for sheds, extensions and outdoor rooms
- Paths and patios around family homes
- Exposed aggregate driveways for homes being updated
- Repairs to lifted edges and corner cracks
On clay, the unglamorous parts of the job decide how long the concrete lasts. A compacted base of the right depth, reinforcement placed where it works, control joints at sensible spacing and drainage that keeps water away from the slab edges. The local concreters we work with treat these as standard, not extras.
What concreting costs in Woronora Heights
As a guide, plain concrete typically costs around $75 to $150 per square metre laid, with exposed aggregate and decorative finishes costing more. Allow for base preparation on clay ground, which may add to the quote but is the cheapest insurance a slab can have.
Any residential concreting job over $5,000 (labour and materials, including GST) must be done by a licensed contractor under NSW law. For work over that amount, ask for the licence number and check it before you sign.

Frequently asked questions
Why does concrete crack so readily around Woronora Heights?
Reactive clay soils are the usual culprit. Seasonal wetting and drying moves the ground under the slab. Concrete built with proper base, reinforcement and joints handles the movement, and older pours often had none of the three.
Does keeping water off the slab really help?
Yes, more than most people expect. Downpipes that discharge beside a driveway keep the clay underneath swinging between wet and dry. Fixing drainage protects the new concrete.
