Concrete Driveways in Audubon
JLB pours residential driveways across Audubon on a subgrade prepped for the town's loess-over-clay ground, using an air-entrained mix in the 5-7% range so the slab can take the 100-120 freeze-thaw cycles a west-central Iowa winter delivers without spalling. On the sloped lots that run toward the East Nishnabotna, that drainage-conscious base prep is what keeps a new drive from heaving where the hillside soils stay wet.
