Cost to pour a concrete slab in Texas

What is the Cost of a Concrete Slab in Texas?

When having a concrete slab installed, be aware that most contractors will estimate the cost of your project based on the overall square footage of the slab. On average, homeowners should expect to pay between $8 and $20 per square foot towards the cost of a concrete slab in Texas. The overall cost to prepare, pour, and finish a concrete slab will depend on its size, finish, ease of access to the job site, and a few more reasons discussed below.

How Much is a 10×10 Concrete Slab?

On the smaller side, a 10×10 concrete slab would be the approximate size of a shed floor or a 2-person bistro seating area. A 10x10 slab or a 100-square-foot concrete slab may cost between $800 and $2,000. Although it is a smaller slab installation, most concrete companies will have a minimum charge of at least $2,000.

How Much is a 10×20 Concrete Slab?

A 10×20 concrete slab would be considered a medium-sized slab, the equivalent of a 4-6-person patio seating area. A 10×20 concrete slab or 200 square feet of concrete may cost between $1,600 and $4,000. The 10×20 slab may cost less per square foot than a 10×10 slab, but a homeowner can still expect to pay an inflated price per square foot due to the smaller quantity. A 200-square-foot concrete patio slab pour will likely require a concrete truck and incur a small batch fee.

How Much is a 20×20 Concrete Slab?

At 400 square feet, a 20×20 concrete slab would be sufficient for a 6- to 8-person backyard patio seating area with a grilling area. A 20×20 concrete slab or 400 square feet of concrete may cost between $3,200 and $8,000. With the higher overall square footage, most concrete delivery companies will no longer be charging small batch fees, and the square foot price will be lower.

A 20×30 concrete slab would be the equivalent of a 6–8 person backyard patio seating area, outdoor kitchen space, as well as a firepit. A 20×30 concrete slab or 600 square feet of concrete may cost between $4,800 and $12,000. With the larger quantity of concrete, lower pricing is available for the concrete.

Concrete Work Cost Considerations

City Permits

Concrete installation often requires a permit. If your project requires a city permit, you can expect to pay an additional fee. This fee could range between $200 and $400. The fee typically covers the costs for the stone masonry company or concrete company to apply for the permit, pay the permit fees, and coordinate the initial and final inspections.

You may incur additional charges if your home is located outside the normal delivery range of the concrete company, in a rural area, or outside the normal service area of the concrete contractor.

Job-Site Access

Installing a concrete slab in the front yard as opposed to a concrete slab in the backyard is two very different things because of job-site access. You can expect to pay a slightly higher rate if your concrete installation work is in the backyard or in hard-to-reach areas.

Special Tools

If your specific job requires special tools, like a concrete pump, additional charges may apply. A concrete pump may be required if the work area is a great distance from the concrete truck, if there are large sums of concrete being poured, or if severe grades on the property prevent the concrete contractor from transporting concrete from the truck to the work area with a wheelbarrow.


The most time-consuming part of any concrete job is preparation, which may begin with demolition if you have an old concrete slab replaced. You can expect to pay a higher price if your specific job requires the demolition of anything other than dirt and sod.


Most responsible and reputable concrete installation companies will provide you with an estimate that includes capping any sprinkler heads in the installation area. However, if you require that existing irrigation valve boxes and pipes be relocated or if irrigation system diagnoses is needed, additional charges may apply.


A rounded or curved-shaped concrete slab may cost a bit more than a squared slab. There is more labor and time involved to finish a round or curve-shaped slab than a square slab.

Depth and Strength

The depth of a concrete slab is typically 4 inches for most projects, like a sidewalk or patio. However, the depth of a concrete slab may increase if the work area is on a sloped grade or when pouring a driveway slab, which directly impacts the amount of concrete needed and may cost a bit more.

Most concrete projects, like a sidewalk or patio, can use 3,000-psi strength concrete. Should your project require higher-strength concrete, you may pay a bit more.

Type of Finish

Standard concrete slabs typically have a broom finish or trowel finish. This is what you would see on your city sidewalk. However, if your project involves a specialty finish, you can expect to pay a higher price. Your concrete contractor may offer specialty finishes like a salt finish, a stamped finish, or a stained finish to update the look of a concrete patio.

As you can see, the cost of a concrete slab in Texas can vary greatly, so it’s worth your time to do a little research before deciding on the size and finish of your concrete slab project. This will help you have an educated conversation before hiring a stonemason or concrete contractor as well as anticipate the overall costs.
