FAQs — Concrete Cost in Montgomery
How many bags of concrete do I need?
One 80 lb bag yields about 0.60 cubic feet, so you need roughly 45 bags per cubic yard. For large pours, ready-mix concrete is more economical than bags.
How thick should a concrete slab be?
A standard residential slab (patio, garage floor) is 4 inches thick. Driveways should be 4–6 inches. Structural or heavy-load slabs are typically 8–12 inches.
What does concrete cost per yard in the US?
Ready-mix concrete averages $125–$165 per cubic yard for materials. With labor (pouring, finishing), total costs typically range from $170–$220 per cubic yard, depending on your state.
How long does concrete take to cure?
Concrete reaches 70% of its strength in 7 days and full strength at 28 days. You can walk on it after 24–48 hours, but avoid heavy loads for at least a week.
