Concrete slab cost in Hawaii

If you are planning more than one job in Hawaii

The table prices neighboring jobs at their usual sizes using statewide Hawaii wages and prices. Against national midpoints, concrete driveway comes out highest (+49%) and detached garage lowest (+29%), because each job leans on different trades.

Weather windows across Hawaii

Season matters for concrete slab. For each Hawaii metro below we took NOAA's 1991-2020 monthly normals from the nearest suitable station and counted comfortable months for pouring concrete.

Honolulu has the longest comfortable season of the metros we cover in Hawaii at 12 months; Kahului has the shortest at 10 (October through July). Rainfall runs from 16 inches a year in Kahului to 16 inches in Honolulu.

We do not adjust prices by month, because we have no reliable published data on seasonal pricing. Timing is still worth raising when you collect bids.

Optional extras in Hawaii

Extras are quoted nationally and then scaled to Hawaii by the average of the local wage index (1.67) and goods index (1.12), a factor of 1.39. Tick any of them in the estimator above to add them to your total. Treat these as planning figures: an add-on touches different trades than the main job, so the scaling is an approximation.

Concrete slab: what moves the price in Hawaii

• Thickness and mix

  A 4-inch slab uses about 1.23 cubic yards of concrete per 100 sq ft; a 6-inch slab uses about 1.85. Stepping up from a 3,000 PSI to a 4,000-4,500 PSI mix adds $10-$40 per cubic yard (Estimators.us).

• Base and reinforcement

  A compacted gravel base, vapor barrier, and wire mesh or rebar are priced separately by some contractors and bundled by others. Ask which one your quote does.

• Truck and pump access

  If the mixer truck can't back up to the forms, someone has to wheelbarrow it in or hire a pump. Pump or line-pump hire is typically billed per day.

• Small-job minimums

  Many crews have a minimum charge, so a 10x10 pad can cost more per square foot than a 20x20 slab.

• Finish

  A broom finish is the baseline. Stamped, stained, or exposed-aggregate finishes are priced as add-ons on top of the slab.

Hawaii against its neighbors

Hawaii ranks 1 of 51 (the 50 states plus DC) for concrete slab, where 1 is the most expensive. The costliest is Hawaii at $5,150 and the cheapest Arkansas at $3,350, both for 400 sq ft at the midpoint. Hawaii sits at $5,150. The five states closest by workforce center are listed below.

Quality levels and sizes in Hawaii

The cited range is cut into three overlapping bands (basic, standard and premium) and scaled to statewide Hawaii wages and prices. The grid prices the same bands at 5 common sizes.

Hawaii metro-by-metro prices

2 of the 2 metros sit above the statewide midpoint of $5,150, and the top-to-bottom gap is 2%. Each row prices the default size with that metro's own BLS wages and BEA price levels, so the gap between rows is real local variation rather than a flat markup.

Hawaii labor market for concrete slab

Statewide wages come from BLS's state-level estimates, which blend big cities with small towns and rural areas. 4 trades drive the labor line for this job, and the weighted ratio against the national wage level is 1.67 for Hawaii.

For cement masons and concrete finishers (47-2051, weighted 50%) the local median is $46.10 an hour, which is 68% above the national $27.41. The middle half of them earn between $32.36 and $47.69 an hour. BLS counts 650 of them working in the state, 10.4 for every 10,000 jobs (US: 13.3), so the local bench is thinner than average.

Construction laborers (47-2061), 30% of the weighting: a median of $37.07 an hour, 64% above the US median of $22.66. The middle half of them earn between $25.13 and $42.19 an hour. About 4,580 work in the state. That is 73.0 per 10,000 jobs, compared with 70.5 nationally, so the supply of crews looks typical.

For operating engineers and other construction equipment operators (47-2073, weighted 10%) the local median is $55.70 an hour, which is 94% above the national $28.78. The middle half of them earn between $35.19 and $58.55 an hour. BLS counts 2,380 of them working in the state, 37.9 for every 10,000 jobs (US: 30.7), so the local bench is deeper than average.

For carpenters (47-2031, weighted 10%) the local median is $41.00 an hour, which is 41% above the national $29.12. The middle half of them earn between $31.91 and $53.36 an hour. BLS counts 4,810 of them working in the state, 76.6 for every 10,000 jobs (US: 43.1), so the local bench is deeper than average.

A crew paid at the 75th percentile for cement masons and concrete finishers ($47.69 an hour) would add about $45 to the statewide midpoint; one at the 25th percentile ($32.36) would take off about $400. Use that as a rough guide to how far a bid can sit from our midpoint on wages alone.

BLS counts 627,530 jobs across Hawaii (May 2025), which is 0.4% of US employment.
