Concrete Driveways in Clarksville, TN

New Driveway or Full Replacement

A new pour usually means a new home or an upgrade from gravel. A replacement means the old slab has failed: broken up, heaving, or sunk low enough to hold water by the garage. We break out the old concrete, haul it away, put down a compacted stone base and pour again.

Not every tired driveway has to come out. If yours is sound but sunken, price repair and leveling first. Want more than a broom finish? A driveway can also be stamped.

Old concrete has to go somewhere legal. Montgomery County's sinkhole information sheet notes that it's illegal to dump dirt, trash or building materials in or around a sinkhole^[1], so ask any contractor where your old slab will end up.

What Goes Under and Inside a Driveway

Plenty of driveway failures start in the layers nobody sees once the concrete is down.

The base

We grade and compact the site, then place a compacted gravel or crushed stone base sized to your soil and to what will park on it. For comparison, TDOT's standard drawing for concrete driveways built on state projects and state right-of-way calls for a 6-inch slab, unless the plans say otherwise, over at least 4 inches of mineral aggregate base^[2]. That's the state DOT's standard for its own work, not a rule for every driveway.

The reinforcement

Driveways get rebar. Wire mesh is hard to hold in position during a pour and often ends up at the bottom of the slab, where it does little. Fiber reinforcement is also an option on every pour.

The mix and the joints

For exterior slabs that stay damp, freeze and see deicers, NRMCA recommends ordering 4,000 psi concrete, consistent with ACI 332, the residential concrete code^[3]. We keep the water-cement ratio low, since extra water makes concrete weaker. Control joints go in at the correct spacing, and NRMCA says a joint groove should be at least a quarter of the slab's thickness^[4].

Slope, Drainage and the Curb

Water should leave your driveway toward the street or a part of the yard that can take it, never back toward the garage. We plan drainage as part of the job, so the slab doesn't pool water at the garage door.

The apron, where the driveway drops to meet the road, has its own grade limits in TDOT's standard drawing for driveways on state projects and right-of-way: 15% at most for a residential apron, with 10% recommended^[5].

Permits where the driveway meets the road

We handle permit pulls where they're required. The section in the public right-of-way answers to whoever owns the road:

• City streets. Clarksville's 2006 access ordinance calls for a Street Department access permit before a curb or right-of-way is cut or paved for a driveway^[6]. It may have been amended since, so confirm current practice with the Street Department.
• County roads. Montgomery County's Highway Department must approve right-of-way work. It inspects the site and sets the culvert size, and a driveway that needs no culvert pays a $250 frontage fee^[7].
• State highways. A driveway on state right-of-way needs a TDOT highway entrance permit, and residential owners start with the local TDOT district office^[8].

Why Driveways Crack Here

Clarksville averages roughly 70 days a year that freeze overnight and then thaw^[9]. Water in or under the slab expands when it freezes, which is why NRMCA says concrete exposed to freezing and thawing should be air-entrained^[10].

The ground matters too. In the USDA soil survey of Montgomery County, Baxter soils make up most of two soil associations that together cover about half the county^[11], and the survey describes them as deep and cherty with a reddish clay subsoil^[12]. Soil varies from lot to lot, which is why the stone base under every slab we pour is sized to the soil.

Much of the rest is workmanship: compaction, joint spacing and a mix that isn't too wet. You can't make concrete crack-proof, but a driveway built right shouldn't crack early or unevenly.

The first winter

NRMCA advises against deicing chemicals during a new slab's first winter and suggests clean sand for traction instead^[13]. Our guidance lines up: no de-icing salts the first winter. We also recommend sealing the driveway every 2–3 years.

What a Concrete Driveway Costs

A standard concrete driveway runs a ballpark $9–$13 per square foot. That's a rough range, not a quote: the price is confirmed at a free on-site visit, because soil conditions, access and site prep can change the total. What moves it:

• Size. The ballpark is per square foot, so a bigger driveway costs more.
• Tear-out. Breaking out and hauling away the old driveway adds to the price.
• Reinforcement. Rebar or fiber adds to the price.
• Site prep and access. Regrading, building up soft ground, or a spot the concrete truck can't reach can change the total.
• Finish. A stamped driveway is priced as decorative work, around $14–$20 per square foot.

What that works out to by size

Take the square footage and multiply it by the range. TDOT's standard drawing lists 12 feet as a typical residential driveway width, or 14 feet for two-way^[14], so most drives here land somewhere near the runs below. Measure yours the same way — length times width — then multiply by 9 and by 13.

Ballpark only, at $9–$13 per square foot: the area multiplied by the range and nothing else. A new pour on ground that needs no tear-out and no unusual site prep.

Driveway	Square feet	Ballpark total
One car, 10 × 20 ft	200	$1,800–$2,600
Standard, 12 × 30 ft	360	$3,240–$4,680
Two cars, 20 × 20 ft	400	$3,600–$5,200
Long run, 12 × 50 ft	600	$5,400–$7,800

Reinforced or not: why two quotes sit far apart

A per-square-foot number only means something once you know what is under it. Our range is for a driveway with a compacted stone base, rebar or fiber through the slab, and control joints cut to depth. Thin the slab, leave the reinforcement out and pour on graded dirt instead of stone, and the per-foot price comes down. The quote can be honest and still be for a different driveway than the one you asked about.

So compare the specification, not the total. Ask every bidder for four numbers: slab thickness, base depth, reinforcement type and joint spacing. Where two quotes are a few dollars a foot apart, the gap is usually sitting in those four lines, and it shows up years later as a slab that cracks early or settles.

What the range does not include

Tear-out is priced at the visit rather than published as a figure, because it depends on how thick the old slab is, whether it was reinforced, and where the truck can park to load it out. Building up soft ground or regrading for drainage works the same way. Fees for work in the right-of-way are separate again — our Clarksville driveway permit guide sets out which office is involved and when. None of those are in the table above.

A line-item estimate first

You get a line-item estimate before we pour, and no change orders you didn't sign off on. It breaks out square footage, slab thickness, base, reinforcement and any tear-out as separate lines, so you can set it beside anyone else's number and read the two line for line.

Questions to Ask Any Driveway Contractor

• What base goes under the slab, and how is it compacted?
• Rebar, fiber or wire mesh, and how will it stay in position during the pour?
• Where will the control joints go, and how deep will they be?
• Which way will water drain, and who pulls the permit for work in the right-of-way?
• Are you licensed for this job? Tennessee currently requires a Home Improvement license for residential projects from $3,000 to $24,999, driveways included, in nine counties that adopted the law, among them Davidson, Robertson and Rutherford; Montgomery County isn't on the list^[15].
