Hawaii Island, the largest of the Hawaiian archipelago and often called the “Big Island,” is a hub of volcanic landscapes, ultra luxury resort custom builds, and resilient local communities. Its construction sector, driven by state projects, residential expansions, tourism infrastructure, and post-storm recovery efforts, relies heavily on concrete for foundations, roads, and coastal fortifications. However, the island’s remote location amplifies costs through elevated shipping fees, labor shortages, and local material sourcing challenges. As we look toward 2026, concrete construction prices are projected to rise modestly amid stabilizing national inflation but persistent island-specific pressures. Drawing from 2025 data and forecasts, this article provides a comprehensive breakdown of current costs and 2026 projections. Estimates incorporate Hawaii’s 4.3% construction cost index increase in Q2 2025 (up from 2024), national material inflation trends ease 4-5%, and local factors like a 2.8% statewide consumer price index (CPI) forecast for 2026.
Overall, expect a 4-6% hike from 2025 baselines, pushing average ready-mix concrete to $190-$280 per cubic yard (CY) on Hawaii Island.
Current Baseline: 2024-2025 Concrete Costs on Hawaii Island
In 2024, Hawaii Island’s concrete prices reflected a stabilization, with ready-mix averaging $170-$294 per CY for 3,000-5,000 PSI mixes, adjusted for local delivery.
This is 20-30% higher than mainland U.S. averages due to inter-island and overseas shipping. Key components include:
| Component | 2024/2025 Average Cost | Key Notes |
| Ready-Mix Concrete (2,500 PSI) | $170-$178/CY | New minimum 6 CY loads; includes local aggregates (3/4″ top size). Prices flat since early 2024 per Hawaiian Cement schedules. |
| Cement (1L/PLC) | $150-$180/ton | Imported; stable but vulnerable to fuel surcharges. |
| Aggregates (Sand/Gravel) | $28-$56/ton | Local volcanic sources like, Waikoloa, Pahoa quarries keep costs down; add $40-80/ton for remote delivery. |
| Labor (Place/Finish) | $300-$500/per day | Skilled carpenters/plumbers at $42-$53/hour; shortages add 10-15% premium. |
| Delivery/Shipping | $150-$340/truckload | Fuel-inclusive; inter-island rates $6.56-$7.16/cu. ft. from Oahu. |
For a typical <600sq ft 4-inch reinforced slab (e.g., patio or foundation), installed costs ranged $12.30-$16.65 per square foot (PSF) in 2024, with larger slabs at $14.95-$18.65 PSF dependent on layout, reinforcement and excavation needs.
Hawaii Island premium fluxuations stem from Hilo/Kona logistics, where volcanic terrain demands specialized equipment, such as hydraulic hammers and mass excavations to hit clinker.
Key Drivers of 2026 Price Projections
Several factors will shape 2026 costs, blending national trends with island realities. Hawaii’s construction sector added 1,000 jobs (2.6%) in H1 2025, but a 15,000+ worker shortfall persists, as per usual necessitating mainland imports and adding higher wages to attract them.
Meanwhile, U.S. material inflation is forecast at 4.0-4.4% for nonresidential buildings, with Hawaii’s index up 3.9% YTD.
1. Material Costs: Modest Rises with Local Sourcing Gains
Concrete’s core—cement, sand, and gravel—will see 3-5% inflation, tempered by flat 2024 ready-mix pricing.
National forecasts predict 5-7% overall material growth, but Hawaii’s reliance on imports (e.g., Portland cement from the mainland) adds volatility.
- Cement: Up 4%, to $156-$187/ton. Tariffs on Chinese imports could add 10% if escalated, per ABC forecasts.
enr.com - Aggregates: Stable at $21-$42/ton, thanks to Big Island quarries (e.g., Yamada & Sons, Sanford’s).
- Volcanic cinder/sand from Pahoa keeps premiums low vs. Oahu.
- Admixtures/Reinforcement: Steel rebar up 3%, to $1.80-$2.40/lb., amid global supply chains.
2. Labor Costs: Shortages Drive 5-7% Increases
Hawaii Island’s construction payroll hit 41,300 in 2025, but demand outpaces supply. dbedt.hawaii.gov
Wages for union masons ($40.00/hour+/-) and union carpenters ($52.06/hour +/-) are 20% above California levels, with 2026 projections adding $1.50-$2.50 rise in demand stemming from loss of illegal work force. https://www.velvetjobs.com/salaries/cement-mason-salary
PLAs on state projects over $1.5M could inflate costs further by favoring union labor. thetruthaboutplas.com
3. Shipping and Logistics: Freight Volatility Adds 4-6%
Inter-island rates hold at $6.56/cu. ft. from Oahu to Kona/Hilo, but mainland surges (e.g., diesel up 10% YTD) forecast 5% hikes. hifa.us
Wharfage tariffs rise July 2025, with no dockage increases but higher cargo fees. Expect $160-$360/truckload. hidot.hawaii.gov
4. Regulatory and External Factors
- Permits/Fees: $5,000-$15,000 for slabs; up 3% with inflation.
- Inflation/Tariffs: State CPI at 2.8% for 2025, with warnings of 4% spikes from tariffs unwarranted.
- Sustainability Push: Local aggregates reduce shipping; Type 1L low-carbon cement adoption inflates costs 8%- 12% at present for end users and consumer.
Projected 2026 Costs: Full Breakdown
Applying a 4-6% escalation (blending national 4.2% nonres buildings forecast with Hawaii’s 4.3% index), here’s the outlook for key concrete applications on Hawaii Island.
Projections assume steady demand from $8.4B in government contracts sustaining activity. dbedt.hawaii.gov
| Application | 2025 Baseline (per unit) | 2026 Projection (per unit) | % Change | Key Driver |
| Ready-Mix (2,500-3,000 PSI, 6 CY min.) | $175-$185/CY | $182-$200/CY | +4-5% | 1L material instability, needed admixes for placing 1L cement, readymix pricing increases |
| Foundation Slab (4″ Reinforced) (avg. 1000 sq ft) | $19.80-$32.00 PSF | $20.20-$34.70 PSF | +6%-8% | Form, place and finish, needed admixes for placing 1L cement, readymix pricing increases |
| Driveway/Patio (avg. 600 sq ft) | $5,500-$8,500 total | $6,800-$12,000 total | +8% | Aggregates + finishing, needed admixes for placing 1L cement, readymix pricing increases |
| Commercial Pour (avg. 1,000 CY) | $198,000-$220,000 | $240,000-$315,000 | +8% | Volume discounts offset readmix pricing increases, needed admixes for placing 1L cement |
| Full Custom Home Foundation (2,000 sq ft) | $40,000-$75,000 | $51,000-$97,000 | +8% | Site prep in volcanic soil, materials delivery cost, needed admixes for placing 1L cement, readymix pricing increases |
For a 2,500 sq ft home foundation, total concrete costs alone usually hit $25,500-$29,250, up from $24,500-$28,000 in 2025—part of broader the $300-$600 PSF custom home builds.
Strategies to Mitigate Rising Costs
Builders and homeowners can buffer 2026 hikes:
- Source Locally: Use local quarries, local labor to bolster the community.
- Plan on Buying Now : Lock in 2025 rates for projects by scheduling with your Concrete Contractor now.
- Efficient Design: Opt for slab-on-grade with optimum grading to reduce concrete waste.
- Ensure Licensed Concrete Contractors complete the work to reduce mistakes or costly remove and replacement.
Conclusion: Planning for Resilience
Hawaii Island’s 2026 concrete prices—projected at $182-$200/CY for ready-mix—signal a market of cautious optimism. With construction jobs up 3.1% in 2025 and $308M in new authorizations, demand remains robust, but labor imports and freight risks loom. http://dbedt.hawaii.gov
