From dirt floor to finished slab — ag buildings, shops, and garages done right
There's a moment every barn or shop owner knows: standing on a dirt floor thinking it's finally time. We pour pole barn floors, machine shed slabs, shop floors, and garage floors across Central Minnesota — recently including a 20-yard pour that took a Long Prairie horse barn from dirt to a finished broom-textured slab (see the before and after in our project spotlight).
Big flatwork is its own discipline: the grade has to be right, the base compacted, the thickness matched to what's parking on it — a car is not a skid loader is not a grain truck — and the joints planned so the slab cracks where we tell it to. We spec all of it honestly and pour it clean.






Most pole barn and shop floors in Central Minnesota run $5–$9 per square foot depending on size, thickness, access, and base condition — large simple pours cost less per foot. See the pole barn concrete guide for the full breakdown.
Four inches for cars and light use, five for trucks and most shops, six-plus where heavy equipment or loaded trucks sit. Reinforcement matters as much as thickness — we spec both to your actual use.
Yes — that's most of this work. We grade and compact inside the building, form the doorways, and place concrete with equipment suited to the access.
We coordinate with your hydronic installer — tubing goes in on top of the base, we pour around it carefully. Tell us early so the slab thickness and reinforcement are planned for it.
