Concrete Across Comanche County, OK

Concrete across Comanche County

Comanche County is Fort Sill country, and Lawton holds most of its people. We pour concrete in Comanche County across 5 towns and the acreage between them. Our Wichita Falls team pours the slab and then grinds, coats, or seals the finish, so one spec runs the job from the dirt to the final coat. That covers driveways, shop and barn slabs, garage coatings, and polished floors.

Comanche County ranks fifth in Oklahoma for population, with roughly 121,000 people. About 90,000 of them live in Lawton, the county seat and the largest city in western Oklahoma. The Army drives the economy. Fort Sill covers 90,000 acres and hires more people than anyone else in the county. Government, factory, and store jobs line up behind it. That mix brings commercial pads and shop floors near the post, home drives in Lawton, and farm and acreage pours out in Elgin, Fletcher, and Geronimo.

Which Comanche County towns does Bel Covo serve?

Lawton sits in the middle, about 50 miles north of our Wichita Falls team and about an hour up I-44, and it carries most of the commercial and home work. The smaller towns ring it on the U.S. highways that feed the I-44 corridor.

• Lawton, the county seat and the largest city in western Oklahoma, right next to Fort Sill
• Elgin, a fast-growing bedroom town on the U.S. 277 corridor north of Lawton, near the Richards Spur quarry
• Fletcher, the northeast-corner town out toward the Caddo County line
• Geronimo, a small town on the U.S. 277 spur south of Lawton, reaching to the Cotton County line
• Sterling, a small Comanche County town that’s inside our coverage too

The town links below reach every covered Comanche County town. The smaller places and the rural acreage between them are covered too.

Why does one spec across the county change a Comanche County job?

The same spec that guides a Lawton commercial pad also sets the rebar in an Elgin shop slab and the broom finish on a Geronimo driveway. That keeps the prep and the finish steady across a county of roughly 121,000 people. Nobody hands the trowel work to whoever happens to be closest and hopes it matches. We plan each job from the red-bed clay or granite gravel actually under it, not from a template.

What does concrete work look like across Comanche County?

The Fort Sill economy and the ranch land around it split the county’s concrete work into five clear types. Find yours:

• Commercial and base-side flatwork. Retail pads, shop floors, and loading aprons around Lawton and Fort Sill pour at 4,000 PSI (pounds per square inch, how strong the cured concrete gets) on a packed base. Joints and flatness follow ACI 302.1R, with #4 rebar in the drive lanes.
• Polished concrete floors. We polish Lawton store, warehouse, and showroom slabs to a Mohs 7 to 8 wear surface. On that scratch scale, 7 is as hard as quartz. A granite mix from the Wichita Mountains country shows a pink-and-steel speckle.
• Farm and equipment slabs. Out in Elgin, Fletcher, and Geronimo, shop and equipment pads run 6 to 8 inches thick, with rebar sized to the equipment list. Grain carts and tractors put point loads on a slab that a basic 4-inch spec never planned for.
• Home drives and patios. A standard 4-inch slab goes down on a crushed-stone base, with air mixed into the concrete so freezing nights don’t flake the top. Concrete driveways run $6.96 to $16.43 a square foot, from a plain broom-finished slab up to one with every upgrade.
• Garage and shop coatings. Epoxy and polyaspartic systems from 4 to 20 mils thick serve homes and base housing. We put them down over a slab we’ve checked for moisture first.

What stone and clay sit under Comanche County?

Two stories sit under one county line. Comanche County straddles the seam where the Red Bed Plains meet the Wichita Mountains. The north end rises into the Cambrian Wichita Granite Group around Mount Scott. Near Elgin, the Dolese Richards Spur quarry mines Ordovician Arbuckle limestone and supplies the region’s coarse rock. It’s one of the largest crushed-stone operations in the country.

The rest of the county is Permian red beds. That means shale, sandstone, and smectite clay that swells wet and shrinks dry, with gypsum pockets scattered through it. To beat that movement, we take three steps:

1. We pack the subgrade (the dirt under the slab) to about 95 percent standard Proctor density, a lab measure of how tightly soil can pack.
2. We lay 4 to 6 inches of crushed-stone base.
3. We air-entrain every outdoor pour at 4 to 7 percent. Those tiny air bubbles give water room to freeze through the roughly 70 freeze-thaw cycles a winter here brings.
