Concrete Driveways in Earlham
JLB pours residential driveways across Earlham on a subgrade prepped for Madison County's loess-over-clay hill ground, using an air-entrained mix in the 5-7% range so the slab can ride out the 100-plus freeze-and-thaw swings a central-Iowa winter delivers without spalling. On the sloping lots around the original town grid, that drainage-conscious base prep is what keeps a new drive from heaving where hillside water collects.
- Air-entrained mixes (5-7%) built to survive 100-120 freeze-thaw cycles a winter
- Proper subgrade preparation over Des Moines Lobe glacial till
- JLB's own in-house crew — no subcontractors
- Free inspection plus the JLB transferable warranty
