Resin Bound Driveway Case Study in Castle Hill
A large residential driveway in Castle Hill had failing exposed aggregate with extensive cracking and persistent moss and weed growth through the surface. Poor kerb appeal and maintenance challenges. We rebuilt the base course, corrected drainage, installed edging, and applied a Sandstone resin bound system with long-term permeability and kerb appeal.

Pricing and project context
This 90–110 sqm resin bound driveway surfacing project shows how preparation, repairs, selected finish, access, and handover timing shape a written scope. The driveway needed base correction before surfacing because resin bound systems depend on a stable, draining substrate and secure edge restraints.
FAQs
How much does a resin bound driveway cost in Sydney?
Sydney resin bound paving runs $180–$280/sqm supplied and installed, which puts a 50sqm driveway between $9,000 and $14,000. It is a premium surface — a new exposed aggregate pour is $80–$130/sqm, so resin bound is roughly double. Within the band, base condition is the main lever: overlaying a sound existing slab sits at the lower end, while a new excavated base with sub-base and drainage sits at the upper end. Aggregate selection, edge restraint and access also move the rate.
Can resin bound be installed over an existing concrete driveway?
Yes, provided the slab is sound, stable and not actively moving. Because resin bound is an overlay, cracks that are still moving will reflect through the new surface, so the slab is assessed and prepared first. Reusing a sound base is the cheapest route into resin bound — it removes excavation, sub-base and spoil removal — which is why those jobs sit at the lower end of the $180–$280/sqm band.
What base does resin bound paving need?
A stable, correctly graded base. New permeable installations use 100–150mm of compacted crushed sub-base with a permeable binder course; BS 7533-13 specifies a crushed 4/20mm aggregate with at least 30% voids. Edge restraint goes in before laying. Typical laid thickness is 15–20mm for paths and pool surrounds and 18–25mm for driveways.
