How Much Does Concrete Cost in Iowa?
Concrete averages $156.75 per cubic yard in Iowa as of 2026 research, with metro-level pricing ranging from $145.78 (lowest-cost metro) to $159.89 (highest-cost metro). That's 5% below the national midpoint of $165.00 per cubic yard (source; confidence: high). The state midpoint is computed by applying Iowa's 0.95× regional adjustment to the national-average dataset documented on our pricing methodology page.

What Drives Concrete Pricing in Iowa?
Iowa prices roughly 5% below the national midpoint — a central-Midwest, heavily agricultural market with abundant local limestone aggregate and established ready-mix and paving networks. Costs run higher in the Des Moines and Iowa City metros and softer in smaller and rural markets. Deep-frost footings and radon-resistant detailing add to residential foundation scope statewide.
Climate and supply factors: Iowa footings must reach well below a deep frost line (roughly 42-48 in), and freeze-thaw cycling drives spalling and heave concerns for concrete and foundations. Soils vary sharply across the state — thick wind-deposited loess in the west, young, poorly drained glacial till and closed-basin topography on the north-central Des Moines Lobe — which affects bearing, drainage and the widespread use of subsurface tile drainage on agricultural sites. Iowa also has the nation's highest average indoor radon, and every county is EPA Radon Zone 1, so radon-resistant construction and sub-slab detailing are common design considerations.
Concrete Prices by Iowa's Major Metros
Per-metro estimates apply each metro's population-weighted price tier to the Iowa state midpoint. Population figures are 2024 ACS estimates from the U.S. Census Bureau.

|---|---|---|---|
| Des Moines | 213K | $159.89 | +2% |
| Cedar Rapids | 138K | $153.62 | -2% |
| Davenport | 101K | $152.05 | -3% |
| Sioux City | 87K | $145.78 | -7% |

When to Buy Concrete in Iowa
Construction season in Iowa: April through November is the practical building window in Iowa. Deep frost and freeze-thaw cycling make late fall and winter footing and flatwork work difficult and more expensive, so most excavation, foundation and concrete pours are scheduled from spring thaw through late autumn; interior work continues year-round.
Ready-mix pricing peaks in May-July when residential and commercial demand stack; cold-weather pours add curing-protection cost in northern states. For non-emergency work in Iowa, ordering during the off-peak window typically saves 5-15% vs. spring/summer peak pricing. Material yards run promotional pricing twice a year — early-spring (Mar-Apr) on bagged products and late-fall (Oct-Nov) on bulk aggregates as plants clear inventory before shutdown.
Climate & Code Considerations for Concrete in Iowa
Frost line: 42-48 in (Iowa is a deep-frost state; ~42 in is the common design depth used across Des Moines, Cedar Rapids and Davenport, with far-northern counties running toward 48 in. Iowa's code sets no single statewide value — the frost depth is fixed by the local jurisdiction per IRC Table R301.2(1), so confirm with the building department.). Iowa's frost line drives footings and bases below the frost depth, adding 25-50% more concrete (or aggregate base) to perimeter foundations vs. southern states with no frost requirement.
State / local code: Iowa administers a State Building Code through the Building Code Bureau (whose code commission historically sat in the Department of Public Safety's Fire Marshal Division and building-code plan review now runs through the Department of Inspections, Appeals & Licensing). Under Iowa Code Chapter 103A, only portions of that code apply mandatorily everywhere — most notably state-owned buildings, factory-built (manufactured and modular) structures, and statewide energy provisions. For general residential and commercial construction, adoption is largely a local option: cities and counties may adopt the State Building Code, adopt another nationally recognized code, or enforce none at all. Larger jurisdictions commonly adopt a recent edition of the International Residential Code (IRC).
Where to Source Ready-Mix Concrete in Iowa
Authoritative directories for sourcing ready-mix producers, aggregate quarries, and bagged-product retailers across Iowa:
- Iowa Ready Mixed Concrete Association (ConcreteState)
- NRMCA ready-mix producer directory (filter by state)
- Quikrete dealer locator
Get quotes from at least three local suppliers — pricing on the same spec varies 10-20% across producers in the same metro. Volume orders (10+ cu yd ready-mix, 20+ tons aggregate, full pallets bagged) typically earn another 5-10% off published quotes.
Calculate Concrete for Your Project
To budget accurately for your pour, calculate how many cubic yards you need, then apply Iowa's 0.95× adjustment to the national-average cost displayed on the calculator. The calculator's built-in cost overlay uses national pricing — multiply the displayed total by 0.95 for a Iowa-specific estimate, or use the per-metro figures in the table above for tighter budgeting.
Frequently Asked Questions
How much does concrete cost per cubic yard in Iowa?
Concrete averages $156.75 per cubic yard in Iowa, with a metro range of $145.78 to $159.89 as of 2026. Iowa pricing runs about 5% below the national midpoint.
What is the cheapest Iowa metro for concrete?
Sioux City typically prices the lowest of the major Iowa metros, around $145.78 per cubic yard. Des Moines typically prices the highest, around $159.89. Differences come from delivery distance to producer plants and metro-area labor rates.
When is the best time of year to buy concrete in Iowa?
April through November is the practical building window in Iowa. Deep frost and freeze-thaw cycling make late fall and winter footing and flatwork work difficult and more expensive, so most excavation, foundation and concrete pours are scheduled from spring thaw through late autumn; interior work continues year-round. Ready-mix pricing peaks in May-July when residential and commercial demand stack; cold-weather pours add curing-protection cost in northern states. For non-emergency work, ordering off-peak (late fall in cold-winter states, mid-winter in southern states) typically saves 5-15% vs. spring/summer peak pricing.
What code requirements affect concrete costs in Iowa?
Iowa administers a State Building Code through the Building Code Bureau (whose code commission historically sat in the Department of Public Safety's Fire Marshal Division and building-code plan review now runs through the Department of Inspections, Appeals & Licensing). Under Iowa Code Chapter 103A, only portions of that code apply mandatorily everywhere — most notably state-owned buildings, factory-built (manufactured and modular) structures, and statewide energy provisions. For general residential and commercial construction, adoption is largely a local option: cities and counties may adopt the State Building Code, adopt another nationally recognized code, or enforce none at all. Larger jurisdictions commonly adopt a recent edition of the International Residential Code (IRC).
Where can I find concrete suppliers in Iowa?
Start with the Iowa Ready Mixed Concrete Association (ConcreteState), the NRMCA national producer directory filtered to Iowa, or the Quikrete dealer locator for bagged products. Get quotes from at least three local suppliers — pricing varies 10-20% across producers in the same metro.
Why is concrete more expensive in Iowa than the national average?
Iowa prices roughly 5% below the national midpoint — a central-Midwest, heavily agricultural market with abundant local limestone aggregate and established ready-mix and paving networks. Costs run higher in the Des Moines and Iowa City metros and softer in smaller and rural markets. Deep-frost footings and radon-resistant detailing add to residential foundation scope statewide.
