Concrete contractors in Boise, Idaho

What these Idaho records tell you

These selected businesses have active general contractor registrations in Idaho DOPL records. We matched each record to a business website publishing the same registration number and concrete services. Registration is not a concrete specialty certification, a workmanship rating or proof of permission for your specific project. Confirm current status, required local approvals and the complete job scope before hiring.

Check each business with Idaho DOPL's official registration search. A listing is not a workmanship rating, a verified customer review or confirmation that the business participates in our referral service. We do not independently verify insurance; request current documentation directly.

Where the listed businesses are based

Business locations represented on this page: Meridian, Nampa. County, parish, borough, census-area, planning-region and independent-city assignments use the largest Census land overlap for each business ZIP. ZIP centers are approximate; they are not exact business addresses or driving distances.

Cold and freeze-thaw

Freeze-thaw is the main risk for outdoor concrete in Boise. Concrete that is wet when it freezes, especially where deicers are used, can scale. NRMCA recommends air-entrained concrete, about 6 percent total air with ¾- to 1-inch aggregate, and a specified strength of 4,000 psi for exterior slabs exposed to freezing and deicers. Ask every bidder to write the specified strength and air content into the quote. Freezing lows are not only a midwinter issue here: about 37 of them fall in March–May and September–November, so spring and fall pours need a plan for cold nights too. ACI calls for cold-weather precautions when air temperatures are expected to fall below 40°F during the protection period.^{[2, 3]}

Heat and drying

Summer brings about 55 days at 90°F or hotter. High temperatures speed up setting and drying, which raises the risk of plastic shrinkage cracks. For a summer pour, ask the contractor to schedule outside the hottest part of the day and to explain how the slab will be protected from drying too fast.^[4]

At 12 inches of precipitation a year this is a dry climate. NRMCA notes that low relative humidity speeds up moisture loss from fresh concrete, so ask what curing method the contractor will use and for how long.^[4]
