Concrete Driveways in Colfax
JLB pours residential and commercial driveways across Colfax on a subgrade prepped for the South Skunk valley's clay-and-loess ground, using an air-entrained mix in the 5-7% range so a new slab takes the 100-120 freeze-thaw cycles of a central Iowa winter without spalling. On the sloping lots that run down toward the river and out toward Iowa Highway 117, the drainage-conscious base prep is what keeps a fresh drive from heaving where the soil stays damp.
