Question 1

How much does a concrete driveway cost in Sherman?

Accepted Answer

Angi's 2026 national cost guide puts concrete driveways at $8 to $20 per square foot installed, so a 24 by 24 foot two-car driveway typically lands around $4,600 to $8,600 before tear-out, thicker sections, or culvert work. A written fixed price follows an on-site walkthrough. Published cost guides give a starting range, and the property sets the final number. Angi's 2026 guide puts installed concrete driveways at $8 to $20 per square foot, with labor making up roughly half, and lists a 20 by 20 foot driveway at about $3,200 to $6,000 and a 24 by 36 foot drive at about $6,900 to $13,000. Sherman projects move within and beyond that range for five reasons. Tear-out: sawing, breaking, and hauling off an old slab adds cost that a pour over prepared ground does not carry. Base work: on the Blackland clay east and south of town, moisture conditioning and 4 to 6 inches of compacted flex base keep the new slab flat and are a real share of the price, while the sandy ground west of US 75 needs less base and more attention to edge drainage. Thickness and steel: 4 inches with bar on chairs carries cars, and aprons or pads for trailers and RVs run 5 to 6 inches; the driveway thickness guide shows what McKinney and Sherman build their own concrete to. The road end: inside Sherman a new approach needs a city permit and a drawing (the driveway permit FAQ covers it), a state highway connection needs a TxDOT access permit, and county roads bring their own culvert rules. Finish: broom-finish gray prices below stamped or colored work. Compare bids by scope, not total, because a lower number that says nothing about base depth, reinforcement, joints, or haul-off describes a different driveway. The concrete driveway service in Sherman prices each of those as its own line after a free walkthrough, and the concrete versus asphalt comparison covers the other surface option.

Question 2

How thick should a concrete driveway be?

Accepted Answer

A concrete driveway should be 4 inches thick for cars and pickups and 5 to 6 inches wherever trucks, trailers, or RVs load it, over 4 to 6 inches of compacted base. McKinney and Sherman build their own residential concrete at 6 inches. Thickness follows the heaviest load that will regularly cross the slab, not the average one. Four inches over a compacted base carries daily cars and pickups for decades, while 5 to 6 inches belongs at the apron where a trailer swings in, the pad where a boat, RV, or tractor parks, the run to a shop door, and the first stretch off the road where delivery and concrete trucks turn; thickening those areas at pour time costs far less than replacing a cracked 4-inch section later. The cities in this corridor show what they trust on this clay. McKinney's 2026 standard detail for the residential drive approach inside the right-of-way calls for 6 inches of 4,000 psi concrete with #4 bars at 18 inches each way on chairs, inspected before the pour, and Sherman's engineering manual builds residential streets at 6 inches with #3 bars at 18 inches over 8 inches of lime- or cement-treated subgrade. A private drive does not have to match a street, but those numbers are a useful yardstick when one bid says 3.5 inches. Two companion specs matter as much as the inches. The base: thickness cannot rescue a slab poured on loose or wet clay, so subgrade preparation and compacted flex base belong in the written scope. The joints: the National Ready Mixed Concrete Association recommends spacing of 24 to 36 times the slab thickness, about 10 feet for a 4-inch slab and never more than 15, with grooves cut to at least a quarter of the depth. Concrete in the 3,000 to 4,000 psi range with rebar on chairs completes the spec. The full driveway thickness guide walks through each piece, and the driveway service in McKinney states thickness by area in every written scope.

Question 3

Does a concrete driveway need rebar?

Accepted Answer

Yes. On North Texas clay a concrete driveway should have rebar, typically #3 or #4 bars at 18 inches each way, set on chairs so the steel sits mid-slab. Rebar does not stop cracking; it keeps cracks tight and panels level when the clay moves. Every slab cracks as it shrinks, so the question is what happens after. On expansive clay an unreinforced driveway cracks, the cracks widen and step out of level as the soil swells and shrinks, water gets into the base, and the damage compounds. Rebar holds the pieces tight and at the same height. Spacing: #3 bars at 18 inches each way is the common residential spec, #4 bars at 18 inches suit heavier sections, and 24 inches is the widest spacing worth accepting on this ground. The cities use the tighter end for their own work; McKinney's 2026 residential drive approach detail calls for #4 bars at 18 inches each way on chairs in 6 inches of 4,000 psi concrete, and Sherman builds residential streets with #3 bars at 18 inches. Placement: bar lying on the dirt does almost nothing, so it sits on chairs at mid-depth, and that detail belongs in the written scope. Welded wire mesh: the National Ready Mixed Concrete Association notes that mesh will not prevent cracking but tends to keep cracks and joints from opening, and it only works as flat sheet held up in the slab, never as roll mesh walked into the bottom of the pour. Fiber: synthetic micro fibers at 1 to 2 pounds per cubic yard reduce plastic shrinkage cracking in fresh concrete, and macro fibers around 5 pounds per cubic yard can act as non-structural shrinkage reinforcement when the supplier documents their performance, which makes fiber a good companion to bar on clay rather than a replacement. Reinforcement is still the second line of defense; the first is a compacted base, because steel over soft fill only holds broken pieces together. The driveway thickness guide covers joints and base in detail, the thickness FAQ gives the quick numbers, and every concrete driveway scope here states bar size, spacing, and support in writing.

Question 4

How long before you can drive on new concrete?

Accepted Answer

Walk on it after 24 to 48 hours, drive cars on it after about 7 days, and keep heavy trucks off for the full 28-day cure. Concrete reaches roughly 70 percent of its design strength in the first week and its rated strength at 28 days. Concrete does not dry; it cures, a chemical reaction that needs time and moisture. The strength curve is steep early and long afterward: roughly 70 percent of design strength arrives in about 7 days, and the 3,000 to 4,000 psi the mix is rated for is a 28-day number. The practical schedule follows that curve. Foot traffic is fine at 24 to 48 hours. Passenger vehicles wait about 7 days. Concrete trucks, moving vans, loaded trailers, and equipment wait the full 28, and on a rural drive it is worth scheduling deliveries around that window. Cure quality is set in the first week, which is why the scope states the method: curing compound sprayed at finish, or wet curing, either of which slows moisture loss so the surface gains hardness instead of dusting. Texas summer makes this real: a slab poured at 100 degrees and left bare can lose water faster than the reaction can use it, which is why summer pours start at first light and cure protection is not optional. Two first-year rules protect the investment: keep deicing salts off the slab its first winter (the surface is still maturing and salt scaling is permanent), and keep skid-steer turns and trailer jack points off the edges. After that, a correctly built slab does not ask for much for a very long time.

Question 5

Do I need a permit for a driveway in Sherman?

Accepted Answer

Yes, inside Sherman city limits a new or rebuilt driveway approach needs a city engineering permit through the Self Service Portal, with a drawing of the approach. On a state highway TxDOT issues the access permit, and on county roads outside town, Grayson County's driveway and culvert rules apply. Who permits a driveway depends on the road it connects to. Inside Sherman, Development Services issues driveway and sidewalk permits through the Self Service Portal it launched on March 31, 2025, and the permit and drawing must be approved before any inspection is scheduled. The city's drawing criteria ask for the approach width at the property line and at the curb, the flare sizes, the distance from each flare to the nearest property line and curb return, nearby storm inlets, and the water meter location; meters are not allowed inside an approach, the approach should sit 10.5 feet from the nearest drainage inlet unless a variance is granted, and a sidewalk is required unless the Director of Engineering waives it. Sherman's engineering manual adds the geometry: a driveway centerline at 90 degrees to the curb, the drive at least 6 inches above the street gutter where it meets the right-of-way, a residential grade no steeper than 10 percent beyond the right-of-way, and one driveway per residential lot onto a public street unless the City Engineer approves a circular drive. Where a drive meets a state-maintained highway such as US 82, US 377, SH 289, or an FM road, the approach needs a TxDOT access permit whether or not the lot is in a city, and TxDOT's manual sets its angle, width, radii, surface, and drainage. On unincorporated Grayson County land, the county's Development Certificate process covers the driveway: you stake it, the precinct foreman decides whether a culvert is needed and inspects the finished drive, and culvert pipe runs 12 to 36 inches, bought and installed by the owner. The Sherman driveway permits post walks through the three authorities, the driveway thickness guide covers what an approach should be built to, and every driveway scope in Sherman names the permit and who pulls it.
