Concrete questions Raleigh homeowners ask
- How much does a concrete slab cost in Raleigh?
- Materials alone for a 20×20 ft (400 sq ft) 4-inch concrete slab run about $704 in Raleigh. Fully installed — gravel base, forms, reinforcement, labor, and finishing — most homeowners pay $2,280 to $3,800 for the same slab, roughly $5.7–$9.5 per square foot.
- What does ready-mix concrete cost per yard in Raleigh?
- Plan on $142–$176 per cubic yard delivered for a standard 3,000–4,000 PSI mix in the Raleigh area. Orders under about 4 cubic yards usually add a short-load fee of $71–$142, so small pours cost noticeably more per yard.
- Do I need a permit to pour a concrete slab in Raleigh?
- Driveways, sidewalks, and anything structural almost always require one; small detached patio pads sometimes fall under the permit threshold. Confirm with the Raleigh building department before you pour — a permit costs far less than being ordered to remove finished work.
- Is it cheaper to pour concrete myself in Raleigh?
- Labor and finishing account for $3.8–$7.6 per square foot of the installed price, so DIY can roughly halve the cost of a simple pad. But concrete is unforgiving: once the truck arrives you have under two hours to place, screed, and finish. Most first-timers cap DIY at about 100–150 square feet.
- How thick should my slab be?
- Four inches is standard for patios and walkways; use 5–6 inches for driveways or anything carrying vehicles. Going from 4 to 6 inches adds 50% more concrete, so match the thickness to the real use.
- How can I save money on concrete in Raleigh?
- Combine small pours into one delivery to clear the short-load threshold, handle your own excavation and gravel base, and collect at least three written Raleigh quotes — 30% spreads between local bids are normal.
