Pole Barn & Machine Shed Concrete Floors - Des Moines Area Acreages

Pole barn and machine shed concrete floors turn a gravel-floored building into a dry, clean shop, garage or storage barn.

Pouring Inside an Existing Building

Most of our pole barn floors go into buildings that are already standing, so access is the first thing we work out. Can a ready-mix truck back up to the big door? Is the door tall enough for a pump boom, or will the concrete be pumped through a line? Are the posts and girts protected from splash? We check all of it on the site visit, so pour day is all pouring.

Base and Moisture

A gravel floor that's been driven on for years is often a decent start, but it's rarely flat or thick enough. We regrade, bring in and compact more stone where it's needed, and set a vapor barrier if the building will be heated or will store anything that shouldn't sweat. HomeGuide prices vapor barrier at $0.50 to $1.00 or more a square foot.

Thickness for What's Parked There

A barn floor carrying a pickup and a lawn tractor is a very different slab from one carrying a loaded grain truck, a combine or a skid steer with a full bucket. HomeGuide notes that most slabs are 4 to 6 inches thick, with thicker slabs and steel for heavier loads. We set thickness and reinforcement for your heaviest machine and thicken the slab at the overhead door, where wheels hit it first.

Aprons and Wash Pads

The apron in front of the big door takes more abuse than the floor inside. It gets mud, frost and every turning tire. We pour aprons thick and slope them away from the building. A wash-down pad with a slope to one edge or a drain keeps equipment cleaning out of the barn.

Radiant Floor Heat

If you're planning in-floor heat, the tubing and insulation go down before the concrete, and the installer has to be on the schedule with us. Let us know early and we'll coordinate the pour around their work.

Smooth or Broom?

A smooth trowel finish is easy to sweep and good for a shop. A light broom finish gives traction in a barn where boots and tires come in wet. Many owners go smooth inside and broom on the apron.
