The North Dakota Concrete Calculator helps homeowners, contractors, and farmers estimate cubic yards, bag count, and ready-mix costs for any concrete project in North Dakota. ND pricing runs $140–$175/yd — slightly above the national average due to limited batch plants and long delivery distances in rural areas. North Dakota’s extreme winters demand air-entrained, high-PSI mixes and deep footings below the state’s 42–72 in. frost depth. Enter your dimensions and get instant, ND-accurate results.

      North Dakota Concrete Calculator — What You Need to Know

      North Dakota has one of the most demanding climates for concrete in the entire United States. With average winter lows of -20°F to -40°F and a frost depth ranging from 42 in. in the south to 72 in. in the north, every outdoor concrete project must account for extreme freeze-thaw cycles. Air-entrained 4,000 PSI mix is the minimum standard statewide, and the North Dakota Building Code (NDBC) strictly enforces footing depth below frost line. The concrete pouring season in ND is effectively limited to May through September.

      🔵 NDBC Minimum Concrete Requirements

      All outdoor flatwork: 4,000 PSI min + 5–7% air entrainment · Foundations & footings: must extend below frost line (42–72 in.) · W/C ratio: max 0.45 · De-icing salt resistance: required for driveways and sidewalks. Verify local requirements with the North Dakota Department of Labor & Human Rights.

      🚗 ND Residential Driveway

      A standard 10×20 ft driveway at 6 in. needs ~3.7 cubic yards. At ND pricing ($148–$168/yd for 4,000 PSI), material costs $548–$622. Always use 4,000 PSI air-entrained mix — ND driveways face 100+ freeze-thaw cycles per year, destroying lower-grade concrete within 2–3 seasons.

      🚜 Farm / Agricultural Slab

      Agricultural concrete is one of the most common pours in ND. Barn floors, grain bin pads, and equipment slabs typically use 6–8 in. thickness at 4,000–4,500 PSI. A 40×60 ft bin pad needs ~33–44 cubic yards. Fiber-reinforced concrete is popular for farm slabs to reduce cracking.

      🏗️ ND Foundation / Basement

      Most ND homes use full basements due to the deep frost line. A standard 1,200 sq ft basement needs 20–30 cubic yards for walls and floor. NDBC requires footings at minimum 42–72 in. below grade depending on county. Licensed contractor and permit required statewide.

      How to Calculate Concrete Volume — North Dakota

      Calculate cubic feet first by multiplying Length × Width × (Depth in inches ÷ 12), then divide by 27 for cubic yards. In North Dakota, always add a minimum 10% waste factor — remote rural sites often cannot get a second delivery same-day, and leaving a pour unfinished in ND weather is extremely costly. For large farm slabs, use the calculator multiple times for each section and sum the results.

      📐 North Dakota Concrete Formula

      Volume (cu ft) = Length (ft) × Width (ft) × [Depth (in) ÷ 12]
      Volume (cu yd) = Volume (cu ft) ÷ 27
      Order Qty = CEIL[ Volume (cu yd) × Waste Factor ]
      Example: 40 ft × 60 ft farm slab × 6 in = 1,200 cu ft = 44.4 cu yd → Order 49 cu yd

      ⚠️ North Dakota Cold-Weather Concrete Warning

      Never pour concrete when air temperature is below 40°F or forecast to drop below 40°F within 24 hours. ND temperatures can drop 30–40°F in hours. If pouring in spring or fall, have insulated blankets and heated enclosures on standby. Most ND ready-mix suppliers charge a hot-water surcharge of $15–$30/yd for cold-weather pours, and remote rural delivery adds $3–$6/mile beyond 10 miles.

      North Dakota Concrete Calculator — Pricing Reference

      North Dakota ready-mix pricing runs slightly above the national average due to limited batch plant locations, high fuel costs for rural delivery, and the need for specialty cold-weather admixtures. Fargo and Bismarck have the most suppliers and best pricing. Minot, Grand Forks, and Williston run slightly higher. Compare with the Alaska Concrete Calculator for the most extreme cold-climate state pricing comparison.

      North Dakota Concrete Project Tips

      • Always specify air-entrained mix — 5–7% air entrainment is mandatory for all outdoor ND concrete. It is the single most important protection against freeze-thaw spalling and surface scaling.
      • Pour only May through September — ND’s concrete season is short. Spring pours (May) and fall pours (September) should include insulated blanket protection and cold-weather monitoring for 72 hours.
      • Footings must go below frost line — ND frost depth ranges from 42 in. (southeastern ND) to 72 in. (northern ND near Canadian border). Footings above frost line will heave and crack within 1–2 winters.
      • Use de-icing resistant mix for driveways — Request a low W/C ratio (≤ 0.45) and ask your supplier about silica fume or fly ash admixtures to boost de-icing salt resistance for ND driveways and sidewalks.
      • Order 10–15% extra for rural sites — Many ND concrete projects are miles from the nearest batch plant. A second delivery on the same day is often impossible in rural areas. Over-ordering is always the safer choice.
      • Cure concrete for a full 7 days minimum — In ND’s cool spring and fall temperatures, curing is slower. Keep concrete moist and above 50°F for at least 7 days using wet burlap or insulated curing blankets.
      • Agricultural slabs: use fiber reinforcement — For grain bin pads and barn floors subject to heavy equipment, NRMCA-recommended polypropylene fiber-reinforced 4,500 PSI concrete dramatically reduces cracking under point loads.

      ✅ Fargo vs. Bismarck vs. Williston — Pricing Snapshot

      Fargo is the most competitive ND market at $140–$165/yd with several Cemex and local plant options. Bismarck averages $148–$172/yd. Williston (oil patch) and rural western ND run $158–$195/yd due to longer haul distances and higher fuel costs.

      North Dakota Concrete Calculator — Frequently Asked Questions

      How much does concrete cost per yard in North Dakota?+
      $140–$175 per cubic yard for standard 4,000 PSI ready-mix in ND. Fargo is most affordable at $140–$165/yd. Williston and rural western ND run $158–$195/yd. Remote rural sites add $3–$6/mile delivery surcharge beyond 10 miles.
      What PSI concrete is required in North Dakota?+
      4,000 PSI minimum with 5–7% air entrainment for all outdoor flatwork, driveways, and sidewalks statewide. Interior-only slabs (basement floors) may use 3,000–3,500 PSI. Never use non-air-entrained mix for any outdoor ND concrete.
      How deep must footings be in North Dakota?+
      42 to 72 inches below grade depending on location — 42 in. in southeastern ND (Fargo area) and up to 72 in. in northern ND near the Canadian border. All footings must extend below the local frost depth per NDBC requirements.
      When is the best time to pour concrete in North Dakota?+
      May through mid-September is the ideal ND concrete season. June, July, and August offer the most reliable warm weather. Avoid pouring when temperatures are below 40°F or forecast to drop below 40°F within 24 hours of the pour.
      Do I need a permit for concrete work in North Dakota?+
      Yes for structural work. Foundations, footings, basement walls, and structural slabs require a building permit from your local ND city or county. Simple driveways and sidewalks on private property may not require a permit — verify with your local jurisdiction.
      How many cubic yards for a North Dakota garage floor?+
      A standard 24×24 ft garage at 6 in. needs ~10.7 cubic yards including 10% waste. At ND pricing of $152–$172/yd, material costs approximately $1,626–$1,840. Use 4,000 PSI air-entrained mix and seal the floor after 28-day cure for maximum durability.
      Who supplies ready-mix concrete in North Dakota?+
      Major ND suppliers include Cemex (Fargo), Border States Paving, Butler Machinery affiliates, and various local independent plants in Bismarck, Minot, and Grand Forks. Schedule at least 48–72 hrs in advance, especially for large farm pours in rural ND.
