Paving & Driveways in Christchurch

Often yes — asphalt can be overlaid if the base is sound, concrete can sometimes be resurfaced or used as a base for pavers, and sunken block paving can be lifted and relaid on fresh bedding. If the base has failed (widespread cracking, deep ruts), resurfacing only buys a year or two.

Make each contractor state the excavation depth, sub-base material and compacted depth, surface thickness, edge restraints and drainage plan. In Christchurch, also ask what happens to excavated spoil — cartage and disposal is a real cost that cheap quotes quietly exclude.

Yes — water must drain to a lawful outfall or soak into the ground. Many jurisdictions now require permeable paving or on-site soakaways when front gardens are paved, precisely to stop rain sheeting onto the street. A good contractor designs falls and drainage before laying anything.

On a proper base: asphalt 15-25 years, concrete 25-40, block paving 25+ (with occasional re-sanding and weed control), gravel indefinitely with topping up. Sealing asphalt and concrete every few years extends life in harsh climates.

Yes. 'We have leftover asphalt from a job down the road' is a classic scam — the material is often laid thin over no base and fails within months, and the crew is untraceable. Reputable paving firms price from a site visit and written spec, not from surplus material on a truck.

Driveway cost depends on area, material (asphalt, concrete, block/brick pavers, gravel, resin) and how much excavation and sub-base work is needed. Gravel is cheapest, asphalt and plain concrete mid-range, and block paving or resin-bound surfaces the most expensive per square metre. Quotes should always include excavation, sub-base depth and edging.

The section crossing the berm and footpath is council land, needing its own permit, spec and inspection. It is often the most expensive part per square metre, and some councils keep a list of approved crossing contractors.
