Concrete Driveways in Gilbert
JLB pours residential driveways across Gilbert on a subgrade prepped for the swelling Des Moines Lobe clay under Story County, using an air-entrained mix in the 5-7% range so the slab can ride out the roughly 100-120 freeze-thaw cycles a central Iowa winter delivers without spalling. On the newer subdivision lots north of Ames, where graded farm fill is still settling, that careful base prep is what keeps a fresh drive from cracking and heaving in its first few seasons.
