Concrete Driveways in Eldora
JLB pours residential and commercial driveways across Eldora on a subgrade prepped for Hardin County's heavy Iowan Surface clay, using an air-entrained mix in the 5-7% range so the slab can absorb the roughly 100-to-120 freeze-thaw cycles a north-central Iowa winter delivers without spalling. On the older lots near the courthouse and the homes closer to the Iowa River valley, that drainage-conscious base prep is what keeps a new drive from heaving where the seasonal groundwater stays high.
