Concrete Driveways in Granger
JLB pours residential driveways across Granger on a subgrade prepped for the clay-rich ground that runs under this part of Dallas County, using an air-entrained mix in the 5-7% range so the slab can ride out the 100-plus freeze-thaw swings a central Iowa winter delivers without spalling. On the newer additions off Highway 141 where the ground was recently graded farmland, that drainage-conscious base prep is what keeps a fresh drive from heaving as the fill underneath continues to settle.
- Air-entrained mixes (5-7%) built to survive 100-120 freeze-thaw cycles a winter
- Proper subgrade preparation over Des Moines Lobe glacial till
