Concrete Parking Lots in West Des Moines, Iowa The Lot You Pour Once Instead of Patching Every Spring

Over the years you own the lot, usually yes. Asphalt's lower install price gets consumed by endless sealcoating, patching, and overlays, while a concrete lot carries traffic for decades. Counting full lifecycle cost, the single concrete pour often beats repaving twice in twenty years.

Below central Iowa's 42-inch frost line. Frost heave lifts anything bearing shallower than that, which cracks lots along the perimeter, so JLB sets footings and edge details beneath the frost depth so the slab stays flat through the deep winter freeze.

On rolling ground, snowmelt and rain run downhill and cut across an unplanned lot. We engineer deliberate pitch, swales, and catch basins so water leaves on a controlled path instead of pooling in low spots where it freezes and breaks the concrete apart.

Snow that melts during the day and refreezes overnight is what works concrete apart cycle after cycle. On a slope it has to be carried off fast, so JLB grades the lot and sets the drainage to move melt off the surface before it can refreeze.

Far less than it damages asphalt. JLB pours a dense, air-entrained slab that resists the salt and plow scraping that degrade asphalt every winter. The tight mix and entrained air keep the surface from scaling under repeated de-icing.
