How Much Does a Concrete Slab Cost in Las Vegas?

For a concrete slab in Las Vegas, one national cost guide lists $6 to $12 per square foot installed. Another lists $4 to $8. Those are published ranges, not our prices. Thickness, steel, caliche in the dig, access and removing an old slab move a job inside or past them.

What does a concrete slab cost per square foot?

One national guide puts a poured concrete slab at $6 to $12 per square foot installed. Materials run $3 to $7 of that and labor $3 to $5. Another guide lists $4 to $8. The type of slab sets the thickness and steel, and both change the price.

The table lines up published ranges by slab type. A casita slab or a foundation is priced from its plan.

A plain slab is priced by the square foot, so size drives the total. A garage floor for two cars is listed at $2,400 to $6,900 installed. Driveways carry vehicle loads, and our concrete driveway cost guide prices them on their own.

We pour patio slabs, shed and casita pads, RV pads, equipment pads and garage slabs for homeowners. Builders, general contractors and property managers call us for commercial pads poured to drawings. Our page on the slabs, pads and flatwork we pour covers how the work goes.

What makes a slab cost more in Las Vegas?

Caliche in the dig, thickness, steel, base gravel, access and summer pour timing all change what a slab costs here. Removing an old slab adds its own line. Each one belongs on an itemized bid. Together they explain why two quotes for the same size slab can sit far apart.

Caliche is a cemented hardpan that sits under many valley lots. One national guide prices ordinary digging at $2.50 to $15.00 per cubic yard. Rock that needs a jackhammer runs $50 to $200 or more per cubic yard.

One published Las Vegas estimate lists excavation at $210 to $360 per hour for a machine and operator. It assumes normal soil and notes that sites with hardpan cost more. A patio slab needs only a shallow cut. Caliche matters most where grade comes down or a footing goes in.

Thickness is concrete you pay for by the yard. One guide notes a cubic yard covers about 81 square feet at 4 inches. At 6 inches the same yard covers about 54, so a 6 inch slab takes half again as much concrete.

Steel is the next line. One guide lists wire mesh at $0.15 to $0.30 per square foot, and another at $0.35. A third calls wire mesh the more affordable option next to rebar. Where a plan calls for rebar, we tie it on chairs so it sits inside the slab.

Base work comes before the concrete. One guide puts gravel for a pad base at $1 to $3 per square foot. The same guide lists leveling or regrading a yard at $0.40 to $2.00 per square foot.

Access changes the labor. A backyard reached only through a side gate means a pump or wheelbarrows. One guide puts concrete pumping at $800 to $1,800 for most residential jobs, or $150 to $250 per hour.

Summer changes the timing. Heat shortens the window to place and finish concrete, so summer pours start early in the day. One guide lists cooled concrete for extreme weather at $30 to $100 per cubic yard.

Small pads carry a truck cost. An AC pad or a small shed slab can come in under a full truck, called a short load. One guide says a short load adds $53 per cubic yard, and another lists $40 to $60.

Finish and joints round out the bid. A broom finish is the plain option. Control joints get cut so the slab cracks along a line we chose. A sealer is an added line if you want one.

How thick should a concrete slab be?

For most patios, walks and shed pads, 4 inches. The residential code adopted in Clark County sets a concrete slab-on-ground floor at not less than 3 1/2 inches thick. One guide says most slabs run 4 to 6 inches, and heavier loads and foundations follow the engineer’s plan.

The code number is the minimum. One national guide advises at least 4 inches for a porch, sidewalk or patio. Another says most shed slabs are about 4 inches thick.

Heavier loads get more concrete. Home foundations typically run 6 inches with rebar, one guide says. An RV pad, a shop floor or a slab under a casita is sized to what it carries. The plan sets its thickness and steel.

A casita or foundation slab starts at the footing. Our page on the footings under casita and foundation slabs covers that part of the work. Post-tension foundation slabs are a specialty pour by others.

Do you need a permit for a concrete slab in Las Vegas?

Often not for the slab itself. The City of Las Vegas exempts private concrete slabs, sidewalks and driveways not more than 30 inches above adjacent grade. The exemption holds only when there is no basement or story below. Clark County’s code exempts walks and driveways on the same terms.

What you build on the slab is a separate question. The city and the county both exempt a detached one-story shed up to 200 square feet. The exemption covers a shed with no plumbing or mechanical work.

A bigger shed, a casita or a patio cover goes to the permit desk. Clark County requires a permit to construct, enlarge, alter, repair, move or demolish a building or structure.

Plan gas and power lines before the pour, since they run under or beside the slab. The City of Las Vegas requires a permit for gas piping between the meter and any appliance. A licensed plumbing contractor runs that line.

Henderson, North Las Vegas and Boulder City run their own permit desks, so the rule there comes from that desk. We check the rule for your parcel before the pour. If you have an HOA, its approval is a separate step, and that submittal goes in first.

Slab or pavers or stamped concrete?

A plain slab costs less per square foot than stamped concrete. One guide lists stamped concrete at $8 to $19 per square foot installed, slab included. The same guide lists a plain slab at $6 to $12. Pavers have their own published ranges, covered in a separate guide on this site.

Stamped concrete gives a stone or tile look on a single pour. Our breakdown of what a stamped concrete patio costs lays out the price tiers.

Pavers are separate units on a compacted base, so a damaged paver can come out and go back. See paver installation prices in the valley for that side.

A plain broom finished slab is the budget choice for a backyard patio. Our page on plain backyard patio slabs shows how that work goes.

What should a written slab bid list?

A bid you can compare lists the slab size, thickness and steel, the base work and any removal. It names how caliche is billed and who pays for a pump. It covers the finish, the joints and who files any permit or HOA submittal. A single total hides the lines where bids differ.

Ask how rock is billed before anyone digs. One national guide tells homeowners to confirm the contract outlines extra costs if the excavator hits rock that needs jackhammering. In the valley that rock is often caliche, so get the terms in writing.

Ask what happens after the pour. One guide puts foot traffic at 1 to 2 days and vehicles at 1 to 2 weeks. The bid should say who protects the slab while it cures and when you can use it.

How do you get a price for your slab?

Send the rough size, a photo of the spot, and what the slab will carry. We look at the grade, the access and what sits under the dig. Then we send a free written estimate that itemizes the work. Request a written bid for your slab to start.

We pour slabs across the valley, including Henderson, Summerlin, North Las Vegas and Boulder City. Pahrump jobs are on the list too.
