Concrete Driveways in Indianola
On Indianola's hilly Warren County ground, JLB pours residential and commercial driveways over a subgrade graded and compacted to hold the slope steady. The mix carries 5-7% air entrainment so it can ride out the 100-120 freeze-thaw cycles a central Iowa winter throws at it. Around the Simpson College area, where clay-heavy topsoil shifts under older drives, that air-entrained slab and proper base prep are what keep new concrete from spalling its first spring.
