Thickness Follows the Traffic

A parking lot isn't one thickness everywhere. ACI 330, the American Concrete Institute's guide for concrete parking lots, sets thickness by traffic category and by how firm the soil is. In its 20-year design table, car-only parking areas come in at 3.5 to 4 inches on most soils. Lanes that carry daily truck traffic need more, and lanes for heavy trucks call for 6.5 to 9 inches, depending on the soil. Where garbage trucks, buses or semis turn and stop, the slab gets thicker. Where customers park cars, it doesn't need to. On a site with an engineer's plan, we build to the plan. If there's no plan, we'll want to know what trucks use the lot, and how often, before we price it.

Soil, Base and Drainage

Much of the Des Moines metro sits on glacial till that varies a lot from one end of a site to the other. Clay holds water and loses strength when it's wet, which is the soft subgrade that cracks slabs. We proof-roll the subgrade, cut out and replace soft spots, and compact a stone base. Then we grade every section toward inlets or the curb line, because standing water in a lot turns into ice in a travel lane by January.

Joints and Phasing

Joint layout on a lot is planned before the first pour: panel sizes, where the joints meet inlets and islands, and how each pour ties into the next. On a working property we phase the job so tenants, customers and deliveries always have a way in and out, and we plan pours around business traffic.

Why Concrete

Concrete costs more up front than asphalt, but it doesn't need sealcoating and it doesn't soften in July heat or rut under parked dumpsters. HomeGuide puts a well-built concrete driveway at 30 to 40 years with proper maintenance. A lot built with the same care, with the right thickness for the traffic, can last a similar span.
