Frequently asked
Common questions
Concrete or asphalt — which is better?
Concrete lasts longer (30 to 40 years vs 20 to 25 for asphalt) but costs 30 to 50% more up front.
When can I drive on it?
Walking 24 hours; light vehicles after 7 days; full strength at 28 days. Avoid de-icers the first winter.
Will it crack?
Concrete always cracks as it cures. Correctly spaced control joints choose where. Random cracking means joints were not sawn in time.
Can I get a coloured or stamped finish?
Yes. Integral colour at the truck, or stamped pattern from rubber mats. Adds 25 to 40% to base cost.
How long does the work take?
2 to 3 days from break-out to finishing, plus 28 days before heavy use.
Can I park RVs and trailers?
Standard 200 mm slab handles standard vehicles plus occasional RV. For permanent RV use, recommend a thicker slab.
