A driveway gets driven on every day for thirty years. The difference between one that lasts and one that cracks in five is everything you can't see once the truck leaves.
Foot traffic in 24-48 hours; vehicles after 7 days. Full strength takes 28 days - patience here is what the warranty is built on.
All concrete cracks - the trade secret is controlling where. Proper joints and reinforcement mean hairlines happen inside the cuts, not across your slab.
Concrete costs more up front and lasts decades longer with almost no maintenance. We'll give you the honest math for your situation.
