In Dunedin, most decorative concrete installations, such as broom or swirl textures, coloured concrete, and exposed aggregate for driveways, paths, patios, and pads, typically fall within $90 to $200 per square metre. This is guidance only. Final pricing is determined by independent contractors following a site visit, a measured scope, and verification of access and ground conditions.
The budget is shaped by base preparation and access, overall footprint and layout, the finish tier (value textures vs. coloured or exposed), oxide dosage and colour complexity, feature borders or bands, saw-cut patterning, steps/edge details, drainage elements, and any removals or reinstatement. Protective measures around landscaping and facades, as well as extra labour for exposure, washing, or sealing, also influence the totals.
Gradients and soft patches may require undercutting and an additional basecourse to maintain texture and clean joints. Access to rear sections, narrow side paths, or elevated sites can slow production or necessitate the use of a small pump. For exposed aggregate, allow for water supply and safe slurry management during wash‑off. Cool southerlies, sea air, and shade can extend curing times, affect retarder performance, and shift the programme.
A baseline slab specification underpins decorative work. From there, finish choice drives detail and time: broom or light swirl for value and grip; coloured concrete where batch control and oxide dosing consistency matter; exposed aggregate requiring retarder application, wash/brush timing, and clean‑up. Many owners request a small sample panel or off‑cut to confirm colour/exposure. Sealing is an optional extra that deepens colour, enhances stain resistance, and simplifies maintenance; reseal intervals vary with use and exposure.
Confirm each proposal covers the same finish and scope. Check:
- GST status (inclusive or exclusive)
- Slab thickness and any reinforcement notes
- Base preparation depth and basecourse specification
- Finish specification: texture type, colour code/oxide dose, aggregate mix and target exposure level
- Joint layout and any feature borders, bands, or saw‑cut patterns
- Sealing: product, number of coats, and timing
- Inclusions/exclusions (removals, spoil, masking/protection, wash‑off management, reinstatement)
- Programme and weather/access allowances
Allow 1 to 2 days for excavation, trimming, and boxing, then a pour day. Exposed aggregate usually needs a return visit for wash/brush (timing weather‑dependent). Sealing is commonly applied after an initial cure period (often 3 to 7 days) and may add a short site return. Light foot traffic is typically fine after 24 to 48 hours; vehicles generally after about 5 to 7 days, particularly once sealing has cured. Your contractor will advise if conditions or finishes require longer protection.
