Question 1

How much does a concrete driveway cost in Christchurch?

Accepted Answer

The cost depends on size, thickness, finish type, and site preparation. Plain driveways typically range from NZD $60–100/m², while decorative or coloured finishes can cost NZD $100–180/m². Site access and drainage requirements can also affect the price.

Question 2

How soon can I walk or drive on new concrete?

Accepted Answer

You can usually walk on fresh concrete within 24 hours. Light vehicles may be OK after around 7 days. Concrete continues curing and gaining strength for 3–6 months, so avoid heavy traffic until fully set.

Question 3

Do I need a building consent for a new driveway or slab in Christchurch?

Accepted Answer

For standard residential driveways or paths, building consent is often not required. However, altering kerbs, drainage, or footpaths typically requires approval from the Christchurch City Council.

Question 4

What thickness should a residential concrete driveway be?

Accepted Answer

A standard driveway is usually 100 mm thick. If heavy vehicles or machinery will be using the driveway, a thicker slab or additional reinforcement may be needed.

Question 5

What concrete finish options are available?

Accepted Answer

Common finishes include plain broom, exposed aggregate, coloured concrete, stamped designs, and polished surfaces. The finish affects appearance, texture, and slip-resistance.

Question 6

Will coloured concrete fade or change colour over time?

Accepted Answer

Some colour change is natural due to UV exposure and weathering. High-quality integral colouring and sealers reduce fading and help maintain vibrant tones over time.

Question 7

Will concrete crack and what causes it?

Accepted Answer

All concrete will experience minor cracks due to shrinkage as it cures. Cracks are normal and usually controlled with expansion cuts to prevent structural issues.

Question 8

Can old or damaged concrete be resurfaced instead of replaced?

Accepted Answer

Yes. Provided the base is sound, concrete can be patched, resurfaced, or overlaid to restore strength and appearance without full removal.

Question 9

What maintenance does concrete require?

Accepted Answer

Regular maintenance includes cleaning, sealing every few years, and repairing small cracks promptly. Proper care extends the life of both decorative and plain concrete surfaces.

Question 10

Is exposed aggregate concrete slippery when wet?

Accepted Answer

No. The texture of exposed aggregate provides excellent grip, making it safe for driveways, patios, and pool surrounds even in wet conditions.

Question 11

How long does concrete take to fully cure and reach design strength?

Accepted Answer

Concrete gains most of its strength in the first 28 days, but it continues curing and drying for 3–6 months. Full strength and durability are achieved during this period.

Question 12

What factors influence the cost of concrete work?

Accepted Answer

Cost depends on area size, slab thickness, type of finish, site accessibility, ground conditions, drainage needs, and labour requirements. Clear, upfront quotes help avoid surprises.

Question 13

What types of commercial concrete paving do you handle?

Accepted Answer

Question 14

What makes a good concrete contractor in Christchurch?

Accepted Answer
