The right material and build depend on what the surface carries and what is under it. These are the choices people ask us about most, answered for Middle Tennessee clay, slopes, summer heat and winter freeze and thaw.
The price ranges on this page are national figures published by HomeGuide for 2026. They are not quotes from The Nashville Concrete Guys. Local wages, ready-mix prices, truck access, slope and what is under your yard all move the real number. Last checked October 2026.
Concrete or asphalt for a driveway?
Concrete lasts longer and needs less upkeep. Asphalt costs less on day one. National figures put a concrete driveway at $6 to $15 per square foot and an asphalt driveway at $5 to $12 or more, with a 20x20 at $2,400 to $6,000 in concrete and $2,000 to $4,800 in asphalt. Asphalt softens in a Nashville summer and wants resealing every few years. It suits long rural drives. Concrete suits most house lots in town.
Poured concrete or pavers?
Pavers cost more and can be lifted and relaid. Poured concrete costs less and is one solid surface. A paver patio is $10 to $17 per square foot nationally, or $3,800 to $6,800 for a 20x20, against $4 to $12 per square foot for plain concrete. Pavers cope well with a root or a spot that settles, since single units can be reset. They also grow weeds in the joints and can shift on a slope if the edge is weak.
How thick should a concrete driveway be?
Four inches is the usual minimum for cars and light trucks, on a compacted stone base. Go to 5 or 6 inches where a heavy pickup, a trailer, an RV or delivery trucks will sit or turn. The base matters as much as the slab. Four inches over packed stone outperforms six inches over soft clay.
Do I need rebar or wire mesh?
On Nashville clay, we recommend rebar or wire mesh in any slab that carries a vehicle. Steel does not prevent cracks. It keeps cracked pieces locked together and level. Rebar on chairs stays in the middle of the slab where it works. Mesh often ends up on the ground under the concrete unless the crew pulls it up during the pour. Fiber in the mix helps with surface cracking but does not replace steel.
What PSI concrete do I need?
For outdoor flatwork that sees freezing weather, 4,000 PSI air-entrained concrete is the usual choice, and 3,000 to 3,500 PSI is common for interior slabs. Air entrainment matters more than a high number here. It puts tiny bubbles in the concrete that give freezing water room to expand. Ask what mix is on the delivery ticket.
Is stamped concrete worth it?
Stamped concrete is worth it if you want the look of stone or brick and accept the upkeep. It costs $8 to $19 per square foot nationally and needs resealing every few years. It can be slick when wet unless grit is added to the sealer. For a patio you look at every day it earns its cost. For a driveway that takes salt and tires, a plain broom finish with a stamped border is often the better buy.
Should I seal my new concrete, and how often does it need sealing?
Sealing is a good idea in this climate, because it keeps water and deicer out of the surface. Wait until the slab has cured, about a month, unless the product is a cure-and-seal made to go on the first day. How often after that depends on the sealer and the wear: every two to three years is typical for a film sealer on decorative work, and longer for a penetrating sealer on a plain drive. National cost for cleaning and sealing is $1 to $3 per square foot, or $575 to $1,700 for a two-car driveway.
Broom finish or smooth finish? What finish for a steep driveway?
Use a broom finish outdoors. It gives grip in rain and frost. A smooth troweled finish belongs indoors, in a garage or shop, where it is easy to sweep. On a steep driveway, which many Nashville hillsides have, ask for a heavy broom pulled across the slope, not down it, or a grooved finish. Avoid glossy sealers on a slope.
What does a hot tub pad need?
A hot tub pad needs to be flat, level and strong enough for several thousand pounds of water and people. That usually means at least 4 inches of reinforced concrete on compacted stone, and more if the maker's instructions call for it. Check the tub's manual for the required load. Plan the electrical conduit and where splash-out and drain water will go before the pour.
I want a shop slab for a vehicle lift or heavy equipment. What should it be?
Follow the lift maker's slab requirements, which state a minimum thickness and concrete strength at the anchor points. A vehicle lift bolted to a thin or weak slab is a safety risk. Many shop floors are 5 to 6 inches with rebar and thickened pads under the posts. For heavy equipment, tell us the weights and wheel loads. Larger buildings follow the engineer's drawings.
Do I need gravel under a slab? Do I need a vapor barrier?
Yes to gravel under almost every slab here. Four inches or more of compacted crushed stone gives even support and lets water drain instead of sitting in the clay. A vapor barrier, a sheet of heavy plastic under the slab, is needed under enclosed or heated space such as a garage you will finish, a shop with a coated floor or living area. It is not used under driveways and open patios.
What does a pad need to take delivery trucks?
A pad that takes delivery trucks needs more thickness, more base and steel. Six inches or more of reinforced concrete over a deep compacted base is a normal starting point, with joints laid out so wheels do not ride along an unsupported edge. For a dumpster pad or loading area, tell us the truck type. A loaded trash truck is far heavier than anything else that touches most lots.
My pool deck is worn. Resurface, pavers or new poured concrete?
If the pool deck is solid and level, resurfacing is the cheapest route at $3 to $6 per square foot nationally. Use a textured, light-colored coating that stays cooler and grips wet feet. If panels have sunk or tipped toward the pool, replace those panels with poured concrete. Pavers are the choice when you want to be able to lift sections later for plumbing repairs.
My patio is poured against the house. What goes between the slab and the wall?
An isolation joint, sometimes called an expansion joint. It is a strip of compressible material between the slab and the foundation so the two can move separately. Without it, a patio that shifts with the clay pushes on the wall or cracks along it. The slab should also slope away from the house, and the top of the joint is sealed to keep water out.
