Concrete Driveways in Marshall County
New and replacement concrete driveways in Marshall County are poured on a properly compacted base with control joints sized for Iowa's freeze-thaw swings, so a Marshalltown or Gilman driveway resists the cracking and frost heave that ruin slabs set on poor subgrade. We grade for drainage so meltwater runs off instead of pooling and lifting the surface.
- 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
