Who Pours Your Concrete in Clarksville
Our own finish crews do, not subcontractors. The company was started by Chris Torres and Grant Lang, the same owners as The Roof Guys, and the office is on Crossland Ave.
The work covers the whole property: driveways and patios and walkways, stamped and decorative concrete, foundations, garage slabs and shed pads, repair and leveling for slabs that have dropped, and commercial flatwork for lots, pads and ramps.
Sinkholes Come First on a Clarksville Lot
Before anyone lays out a slab here, look for sinkholes and soft low spots. Montgomery County's building department says sinkholes are a common feature of the county and the areas around it[1].
The southeast side has been studied closely. A 2016 peer-reviewed study of the Sango area, on Clarksville's southeast side, counted an average of 5.877 sinkholes per square kilometer and tied growth there to subsidence, sinkhole collapse and flooding[2].
Concrete does not fix a sinkhole
The county's sinkhole sheet warns that filled sinkholes can grow or re-form, and that an engineer or geotechnical professional should be consulted before anyone tries to fix one[3]. If a depression sits where you want a patio or a pad, the layout should move, or the pour should wait for that professional's advice. Covering one with concrete does not change that.
The 60-foot buffer
Montgomery County's stormwater rules require a 60-foot undisturbed buffer around sinkhole throats, cave entrances and Class V injection wells[4]. If one of those is on or next to your lot, find out where that ring falls before a driveway or slab gets drawn inside it.
Where the runoff goes
A new slab sheds water that used to soak in. The county's karst policy treats every sinkhole as a regulated stormwater structure[5], and sending more runoff into a sinkhole requires a state Underground Injection Control permit from TDEC[6]. So the drainage plan for a Clarksville driveway is not only about keeping water off the garage floor. It also has to keep new runoff out of the nearest sinkhole, or get a TDEC Underground Injection Control permit before sending more runoff into it.
Red Clay, Chert and About 78 Freezing Nights
What sits under the slab and what the winter does to it matter more here than the finish on top.
Baxter soils are the most widespread soils in the USDA soil survey of Montgomery County. They are deep and cherty, with a reddish clay subsoil[7]. Soil still changes from one lot to the next, so the compacted gravel or crushed stone base under every slab we pour is sized to the soil and to the load it will carry.
Winter is the other half. Clarksville averages about 78 nights a year at or below freezing[8], and on roughly 70 days a year it freezes overnight and then thaws[9]. Water that gets into concrete expands each time it freezes, which is why NRMCA says concrete exposed to freeze-thaw should be air-entrained[10]. Ask what air content is in the mix before the truck is ordered.
City Street, County Road or State Highway
Which permit a driveway needs depends first on who owns the road it meets, and we handle the permit pulls where they are required.
- Inside city limits. Clarksville has adopted the 2018 International Residential Code for one- and two-family homes[11]. Under the city's 2006 access ordinance, no curb or right-of-way may be cut or paved for a driveway until the Street Department approves an access permit, and that permit comes before the building permit[12]. The ordinance may have been amended, so the Street Department has the final word.
- On county roads. Any right-of-way work needs Montgomery County Highway Department permission, and a driveway that needs no culvert pays a $250 frontage fee[13]. Outside city limits, the county began enforcing the 2018 International Building and Residential Codes on January 1, 2021[14].
- On a state highway. A TDOT highway entrance permit is needed, starting with the local TDOT district office[15].
About Half of Clarksville's Housing Units Date to 1997 or Earlier
Clarksville had about 176,000 residents and a median housing-unit build year of 1997 in the Census's 2020-2024 estimates[16]. So about half the housing units in the city were built in 1997 or earlier. If your driveway, walk or patio went in with a house that age, it has seen a lot of winters.
Old concrete does not always need to come out. A slab that has sunk but is still in one piece is a candidate for mudjacking or polyfoam leveling. A worn but sound surface may take a cement overlay. A slab that is broken into pieces or heaving usually needs replacing, and we break out and haul away the old concrete as part of that job.
From Estimate to Walkthrough
Start with the instant estimate for a ballpark range. Then:
- Chris or Grant gets back to you within 1 business hour, by call or text.
- A free on-site visit confirms the price, because soil, access and site prep can change it.
- You get a line-item estimate before the pour, and no change order you did not sign.
- Every pour gets a compacted base, control joints, and rebar or fiber reinforcement.
- You get the cure time, not just the pour date: walk on it after 24–48 hours, keep cars off for 7 days, and expect it to keep curing for about 28 days.
