Concrete Driveways in Humboldt
JLB pours residential and commercial driveways across Humboldt on a subgrade prepped for the clay-heavy ground that runs through Humboldt County, using an air-entrained mix in the 5-7% range so the slab can absorb the 100-120 freeze-thaw cycles a north-central Iowa winter delivers without spalling. On the older lots near the downtown core and the river forks, that drainage-conscious base prep is what keeps a new drive from heaving where the soil stays wet through spring.
