The Wyoming Concrete Calculator helps homeowners, ranchers, and contractors estimate cubic yards, bag count, and ready-mix costs for any concrete project in Wyoming. Wyoming pricing typically runs $120–$165/yd for standard mixes — near the national average — but rural delivery surcharges can add $50–$100/yd in remote areas. Wyoming's extreme freeze-thaw cycles and high-altitude conditions require air-entrained, properly cured mixes for long-lasting results. Enter your dimensions for instant, WY-accurate results.

Wyoming Concrete Calculator — What You Need to Know
Wyoming concrete projects face two major challenges that set them apart from most other states: extreme freeze-thaw cycles (Wyoming records over 100 freeze-thaw cycles per year in higher elevations) and remote rural delivery, which can significantly increase ready-mix pricing and lead times. Wyoming follows the International Building Code (IBC) with state amendments, requiring minimum 4,000 PSI air-entrained concrete for any flatwork exposed to weather. Always contact your local Wyoming Fire Prevention & Electrical Division or county building department before starting structural concrete work.
🔵 Wyoming IBC Minimum Concrete Requirements
Exposed flatwork (driveways, patios, sidewalks): 4,000 PSI min · Structural exposed to weather: 4,500 PSI · Air entrainment: 5–7% for severe freeze-thaw exposure (Wyoming Exposure Class F2) · W/C ratio: max 0.45. Footing depth must extend below the local frost line — 36 in. in Cheyenne, up to 48 in. in Laramie and higher elevations.
🚜 Ranch / Rural Driveway
A standard 12×100 ft ranch driveway at 6 inches needs ~22 cubic yards. At Wyoming pricing ($130–$155/yd for 4,000 PSI), material alone runs $2,860–$3,410. A WYDOT access permit is required for driveways connecting to state highways.
🌾 Agricultural Barn / Shop Slab
Wyoming barn and shop slabs typically use 5–6 inch, 3,500–4,000 PSI concrete with #4 rebar on 18-inch centers for heavy equipment. A 40×60 ft shop slab at 6 inches requires roughly 27 cubic yards.
🏗️ Foundation / Basement Floor
Wyoming foundations require footings placed below frost depth — 36–48 inches depending on location. Use minimum 4,000–4,500 PSI with a waterproofing admixture. Local county building permits are required for all new foundations.
How to Calculate Concrete Volume for Wyoming Projects
Break your project into simple shapes — rectangles for slabs and driveways, cylinders for post holes and piers. Calculate cubic feet first, then convert to cubic yards by dividing by 27. Always order at least 10% extra — in rural Wyoming, re-ordering can mean a next-day wait and an additional short-load fee. Use the Colorado Concrete Calculator for neighboring state price comparisons.
Example: 20 ft × 10 ft driveway × 6 in = 100 cu ft = 3.70 cu yd → Order 4.1 cu yd (+10%)
⚠️ Wyoming Rural Delivery Surcharges
Ready-mix suppliers in Wyoming often add rural delivery fees of $3–$8 per mile beyond a standard service radius (typically 20–30 miles from the plant). For remote ranch projects, this can add $50–$120 per yard to your cost. Consider mobile mixers or bagged concrete for small remote jobs under 2 yards.
Wyoming Concrete Pricing Reference
Wyoming ready-mix pricing is close to the national average in urban areas like Cheyenne and Casper, but climbs steeply with distance from batching plants. Air-entrained mixes — required for freeze-thaw durability — typically cost $5–$12/yd more than standard mixes.

✅ Wyoming High-Altitude Concrete Note
Cities like Laramie (7,165 ft) and Rawlins (6,759 ft) experience reduced atmospheric pressure, which can accelerate concrete set time and moisture evaporation. Use a set-retarding admixture during warm months and always cure with wet burlap or curing compound for a minimum of 7 days at altitude.
Wyoming Concrete Project Tips
Always use air-entrained mix for outdoor concrete — Wyoming freeze-thaw cycles will destroy non-entrained concrete within 2–3 winters. Specify 5–7% air content.
Dig footings below frost depth — 36 inches minimum in Cheyenne and Casper, 42–48 inches in Laramie, Sheridan, and high-altitude regions per IBC Table R301.2.
Order early in rural areas — Many Wyoming suppliers serve large geographic areas. Schedule your pour at least 1–2 weeks in advance, especially in spring and summer.
Plan for wind — Wyoming is consistently one of the windiest states. High winds accelerate surface drying and can cause plastic shrinkage cracks. Use windbreaks and evaporation retarder during pours.
Check permit requirements — Contact your county building department before pouring any foundation, structural slab, or barn floor. Requirements vary by county across Wyoming.
Cure properly in winter — When temperatures drop below 40°F, use insulating blankets and heated enclosures. Follow ACI 306 cold-weather concreting guidelines — Wyoming winters are severe.
Account for rural short-load fees — Most Wyoming suppliers charge $100–$250 short-load fee for orders under 5–6 cubic yards. For small jobs, Quikrete or Sakrete from local hardware stores is more cost-effective.
$120–$165 per cubic yard for standard 4,000 PSI ready-mix in Wyoming urban areas (Cheyenne, Casper, Gillette). Rural and remote locations can run $160–$220+/yd due to delivery surcharges. Short-load fees of $100–$250 apply for orders under 5–6 yards. Bagged concrete (80 lb bags) costs approximately $9–$10 per bag at Wyoming hardware stores.
What PSI concrete is required for Wyoming driveways and patios?+
Wyoming's IBC-based building code requires minimum 4,000 PSI with 5–7% air entrainment for flatwork exposed to weather (driveways, patios, sidewalks). This corresponds to IBC/ACI 318 Exposure Class F2 (severe freeze-thaw). A maximum W/C ratio of 0.45 is also required. Using 3,000 PSI non-air-entrained concrete outdoors in Wyoming is a common and costly mistake.
How deep should concrete footings be in Wyoming?+
Footing depth must extend below the local frost line to prevent frost heave. Minimum depths in Wyoming: Cheyenne — 36 in., Casper — 38 in., Laramie — 48 in., Sheridan — 42 in., Rock Springs — 36 in. Always verify with your local county building department, as frost depth maps are periodically updated.
How many cubic yards for a Wyoming ranch driveway?+
A typical ranch driveway of 12 ft wide × 50 ft long at 6 inches needs approximately 11.1 cubic yards (plus 10% waste = 12.3 yd). At Wyoming ready-mix pricing of $128–$155/yd, material cost runs roughly $1,575–$1,905. For longer driveways (200+ ft), ready-mix delivery cost and access logistics become the primary planning factor.
Who supplies ready-mix concrete in Wyoming?+
Major Wyoming ready-mix suppliers include Knife River Corporation (plants in Casper and Sheridan), Reiman Corp (Cheyenne area), Western Wyoming Concrete (Rock Springs / Green River), and Vulcan Materials / local affiliates in Gillette. For remote areas, check with your county for the nearest licensed supplier — some rural sites require mobile mixers or long-haul delivery.
Bagged concrete vs. ready-mix in Wyoming — which to use?+
Use bagged concrete (Quikrete/Sakrete) for jobs under 0.5 cubic yards — post holes, small repairs, or isolated footings. For anything larger, ready-mix is more economical once you factor in labor mixing bags. The break-even is roughly a 10×10 ft slab at 4 inches (1.2 cu yd). In very remote Wyoming locations, the added delivery cost may push the break-even point higher toward 2–3 yards.
How long does concrete take to cure in Wyoming?+
24 hrs foot traffic · 3 days form removal · 7 days light vehicles · 28 days full structural strength. In Wyoming winters (below 40°F), insulating blankets are required and curing time extends — follow ACI 306 cold-weather guidelines. At high altitude (Laramie, Saratoga), faster evaporation means keeping concrete moist is especially critical for the first 7 days.
