How Much Does a 40x60 Concrete Slab Cost in Tennessee?
A 40x60 concrete slab — 2,400 square feet — is a significant pour. It's the foundation size for most large pole barns, shop buildings, and multi-vehicle garages we build in Lawrence and Giles County. If you're budgeting a 40x60 building project and trying to understand what the slab alone costs, this breaks it down from our actual job data in this market.
A large building slab with rebar grid in Middle Tennessee — properly formed, reinforced, and ready for the pour.
Quick answer: 40x60 slab cost in Middle Tennessee
A 40x60 concrete slab (2,400 sq ft) in Lawrence or Giles County runs $19,000 to $28,000 for a 4-inch slab with wire mesh. A 5-inch slab with a #4 rebar grid — the right spec for a working shop or vehicle garage — runs $24,000 to $34,000. Site conditions move the number. An on-site estimate is necessary for accuracy.
What makes a 40x60 slab different from a smaller pour
At 2,400 square feet, this is a pump truck job in most cases. A standard concrete chute can reach 12–15 feet from the truck; a 40x60 slab that's fully enclosed or set back from road access needs a pump line to place the concrete accurately throughout the slab. Pump truck rental is $800–$1,500 depending on the day and availability, and it's built into our quote for pours that need it. Some contractors leave this out of an initial number and add it back later — we price it correctly from the start.
The concrete quantity matters at this scale
A 40x60 at 4 inches thick takes roughly 19.5 cubic yards of concrete before waste factor — call it 22 yards ordered. At 5 inches thick, you're ordering around 27 yards. At 6 inches, around 33 yards. In Middle Tennessee's 2025 market, ready-mix concrete runs $165–$195 per yard delivered, so the material cost on the concrete alone is $3,600–$6,400 depending on thickness and mix spec. That's just the material — it doesn't include base prep, labor, forming, or finishing.

|---|---|
| 40x60 slab, 4 in, wire mesh, stable site | $19,000 – $24,000 |
| 40x60 slab, 4 in, wire mesh, clay subgrade | $22,000 – $28,000 |
| 40x60 slab, 5 in, #4 rebar grid, vehicle use | $26,000 – $34,000 |
| 40x60 slab, 6 in, rebar, heavy equipment | $31,000 – $40,000 |
Rebar vs wire mesh on a 40x60 — what to actually use
Wire mesh (welded wire reinforcement) is appropriate for slabs that see foot traffic and light storage. For a 40x60 building where you're parking vehicles, rolling in equipment, or using it as an active workshop, wire mesh is the minimum — and on a 2,400 sq ft slab, a rebar grid is the better investment. Rebar costs more upfront but gives the slab dramatically more crack resistance under point loading from vehicle tires and jacks. On a slab this size, the cost difference between wire mesh and rebar is roughly $2,000–$4,000 — not nothing, but a fraction of the total project and worth it for a shop that needs to perform for 30+ years.
Site grading before a 40x60 pour
A 40x60 building pad needs to be level and drain correctly in all directions. On larger pours, any grade error in the forming gets amplified — a 1-inch slope error across 60 feet creates a noticeably tilted floor that you'll notice every time you sweep the shop. We set a laser elevation on the forms for every building slab we pour and check it at multiple points before any concrete is placed. This is standard practice that not every contractor applies to residential agricultural work.
Frequently asked questions
How much does a 40x60 concrete slab cost in Tennessee?
In Lawrence and Giles County in 2025, a 4-inch slab with wire mesh runs $19,000–$28,000. A 5-inch slab with rebar — right for vehicle use — runs $24,000–$34,000. These are ACS's local numbers based on actual projects in this market.
What is a 40x60 slab typically used for?
Most commonly the floor for a 40x60 pole barn or metal building — comfortably fitting 4 vehicles, a workshop area, and storage. Also used for large garages, equipment storage, and agricultural buildings.
How many yards of concrete does a 40x60 slab take?
At 4 inches: approximately 22 yards ordered. At 5 inches: approximately 27 yards. At 6 inches: approximately 33 yards. These include a 10% waste factor for a proper pour.
Does a 40x60 slab need rebar or wire mesh?
For active vehicle use and working shops, we recommend a #4 rebar grid minimum. Wire mesh is adequate for light storage only. The upgrade from mesh to rebar on a 40x60 costs $2,000–$4,000 and is worth it for slabs that will see real use.
How long does it take to pour a 40x60 slab?
Site prep takes 2–3 days. The pour is one day. Light use after 7 days, heavy vehicles after 28 days. Permit-to-pour timeline is typically 2–4 weeks.
