Cubic yards, bags & Anchorage-accurate ready-mix costs for driveways, foundations, slabs & footings — Municipality of Anchorage AK.
The Anchorage Concrete Calculator helps homeowners and contractors in the Municipality of Anchorage estimate cubic yards, bag count, and ready-mix cost for any Alaska concrete project. Anchorage pricing runs $185–$265/yd — among the highest in the United States due to Alaska's remote supply chain, high labor costs, and extreme climate requirements. Anchorage's 60-inch frost depth demands deep footings on all structures. 4,500 PSI with 6–7.5% air entrainment is required on all exterior concrete due to 60–80 annual freeze-thaw cycles. ACI 306 cold-weather procedures apply roughly October through May. Seismic Design Category E applies across Anchorage — rebar and engineering are mandatory on all foundations. All work requires a Municipality of Anchorage building permit and Alaska licensed contractor. More tools at Concrete Toolkit.

Residential driveway: 5-6 in. min, 4,500 PSI, 6-7.5% air entrainment required, heated subbase recommended, insulated curing blankets required Oct-May. MOA building permit required. Alaska licensed contractor required.
Driveway 5-6 in · Garage slab 5 in · Foundation wall 10 in+ · Footing 12 in+ at 60 in below grade
Anchorage presents one of the most demanding concrete environments in North America. Three overlapping challenges define every project: extreme freeze-thaw cycling (60–80 cycles per year), a 60-inch frost depth requiring deep footings, and Seismic Design Category E — the highest in the continental US — driven by Anchorage's location on the Pacific Ring of Fire. On top of this, Anchorage's silty and glacial soils have poor bearing capacity in many neighborhoods, and isolated areas around Turnagain Arm and south Anchorage have near-surface permafrost that must be evaluated before any foundation work. All exterior concrete requires 4,500 PSI with 6–7.5% air entrainment and a water-cement ratio of 0.40 maximum. ACI 306 cold-weather procedures apply October through May.
All exterior flatwork (driveways, sidewalks, patios): 4,500 PSI min, 5-6 in. min, 6-7.5% air entrainment, W/C 0.40 max, rebar required · Foundation walls: 5,000 PSI, 10 in. min thick, rebar per AK seismic engineer spec, 60 in. frost depth · Footings: 5,000 PSI min, bottom of footing at 60 in. below grade · Interior heated slabs: 4,000 PSI, vapor barrier, insulation required · Oct–May: ACI 306 cold-weather mandatory — heated enclosures, insulated blankets, heated mix water · All work: MOA building permit + Alaska licensed contractor required.
Anchorage's cold season runs October through May with January lows averaging -5°F and extreme events reaching -30°F. ACI 306 procedures are mandatory whenever ambient temperature is below 40°F — which in Anchorage means essentially 7 months of the year. Requirements: heat mix water and aggregates, target delivery temp 55–65°F, never pour on frozen subgrade (thaw with hydronic heating mats), enclose the pour area with heated tents, wrap finished concrete in insulated curing blankets, and maintain above 50°F for a minimum of 7 days. Unprotected winter concrete in Anchorage will freeze before reaching design strength and must be completely demolished.
Anchorage is served by a small number of local ready-mix suppliers with limited competition — pricing is substantially above the national average. Winter surcharges for heated mix water and cold-weather delivery add $15–$30/yd from October through May. Short-load fees of $175–$350 apply for orders under 3 yards. Pump truck hire is $600–$1,100 for remote or constrained sites. Remote delivery outside the MOA (Wasilla, Palmer, Kenai) carries additional haul surcharges.
| PSI Grade | Anchorage Price / Cu Yd | Air Entrained? | Best For | AK Code |
|---|---|---|---|---|
| 4,000 PSI | $185–$215 | Interior Only | Heated interior slabs, garages (heated) | Interior OK |
| 4,500 PSI | $198–$232 | Required 6-7.5% | All exterior flatwork, driveways, sidewalks | AK Minimum |
| 5,000 PSI | $215–$252 | Required 6-7.5% | Foundations, footings, retaining walls | Compliant |
| 5,500 PSI | $232–$268 | Required 6-7.5% | Commercial, seismic-critical structural elements | Compliant |
Alaska requires all contractors to hold a valid Alaska Contractor License issued by the Alaska Division of Corporations, Business & Professional Licensing. Verify your contractor's license at commerce.alaska.gov/cbpl. The Municipality of Anchorage Development Services Department issues building permits — contact 907-343-8300 before any project. All foundation and structural work requires a licensed Alaska PE (structural engineer). Always confirm current general liability insurance ($1M min) and Alaska workers compensation coverage in writing before signing any contract.
Alaska contractor licensing, MOA building permits, ACI 306 cold-weather standards, and seismic engineering references for compliant Anchorage concrete work.
The Alaska Division of Corporations, Business & Professional Licensing (CBPL) administers contractor registration and licensing for all construction trades in Alaska. Verify any Anchorage concrete contractor's license number, class, current status, and complaint history before signing any contract. Alaska law requires licensed contractors for residential and commercial construction work. Working with an unlicensed contractor in Alaska removes all consumer protections and may void your homeowner's insurance coverage for the work performed.

Contact MOA Development Services at 907-343-8300 or visit 4700 Elmore Road, Anchorage AK 99507 before beginning any project. Foundation and structural projects require a licensed Alaska PE stamped engineering drawings submitted for plan review. Inspections are required at excavation, footing, structural pour, and backfill stages. Always obtain your permit before breaking ground in Anchorage.
Visit MOA Development ServicesACI 306 is essential reading for every Anchorage concrete contractor. It covers heated enclosure requirements, mix water temperature targets, aggregate heating procedures, insulated curing blanket specifications, temperature monitoring protocols, and protection duration requirements for extreme cold climates. Anchorage's subarctic climate — with temperatures below 40°F for 7+ months per year — makes ACI 306 the most important concrete standard for Alaska work. ACI 306 non-compliance is the leading cause of early-age concrete failure, frozen pours, and structural rejection on Anchorage construction projects.
