Paving & Driveways in Sha Tin Wai

A typical residential driveway takes 2-5 days: excavation and sub-base first, then the surface. Asphalt is drivable within days; new concrete should cure about a week before taking a car's weight; pavers can be used almost immediately once compacted and sanded.

A skimped sub-base. The surface layer gets the attention, but 100-200mm of properly compacted hardcore beneath it is what stops sinking, cracking and rutting. Quotes that are far below the rest usually save money underground where you cannot see it.

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 Sha Tin Wai, 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.

Access. Materials often have to be carried by hand up village paths or through buildings, and skilled outdoor trades are scarce. Expect labour to be half or more of the total, and per-square-foot rates well above regional norms.
