Bangor's quiet family streets went in mostly through the 80s and early 90s, which means a lot of the suburb's original concrete is now 30 to 40 years old and sitting on the same reactive clay that runs under the rest of the Menai area. The combination shows. Walk a loop off Menai Road and you will pass driveway after driveway with stepped cracks, lifted corners and patched bays in the 2234 postcode.

Common concreting jobs in Bangor
- Replacing original 80s and 90s concrete driveways
- Concrete repairs for isolated movement cracks and spalled edges
- Concrete slabs for double garages, sheds and granny flats
- Concrete paths and patios around pools and pergolas in Bangor's family backyards
- Exposed aggregate finishes when the front of the house gets a refresh
The pattern in Bangor is predictable. The original driveway was poured with the house, it has done its decades of service on moving clay, and the owners are now deciding between patching it again or replacing it once and properly.
What a concreting job involves
Start with a site visit and a written quote that names thickness, mesh, base preparation and whether old slab removal is included. The job itself runs through demolition, excavation, a compacted road base layer to buffer the clay, formwork, steel mesh, the pour, finishing and curing. Control joints matter on clay, so ask where they will go.
New driveways need about seven days of curing before cars use them.
What concreting costs in Bangor
Plain concrete typically costs around $75 to $150 per square metre laid, exposed aggregate and decorative finishes more. Bangor's double driveways and the extra base work clay demands both push jobs toward the larger end.
NSW law requires a licensed contractor for any residential concreting job worth more than $5,000 (labour and materials, including GST). Check the licence before signing.
Frequently asked questions
My Bangor driveway has a long diagonal crack. Is the house footing at risk?
Not necessarily. Driveways and house slabs are separate structures, and driveway cracking on clay is common and usually affects only the driveway. If you see matching cracks in brickwork, get a building inspection.
Is patching a cracked clay-soil driveway worth it?
For one or two cracks on a sound slab, yes. If bays have moved to different heights, the base has failed and patching only delays the replacement.
How do concreters stop the new slab cracking on Bangor clay?
A compacted granular base, correct mesh placement and control joints at close spacings. The slab still moves, but the joints take the movement instead of the surface.
