Rural Douglas and Lane counties are full of shops, barns, outbuildings, and parking pads that need real concrete. A slab that holds a tractor, a loaded trailer, a thirty-foot fifth wheel, or a working shop with a lift in it has different requirements than a residential patio. We pour those slabs to the right spec.
Thickness, reinforcement, and base
Every shop or barn slab starts with the right base prep and the right thickness.
- Six-inch slab with #4 rebar at twelve-inch grid for shops and barns
- Eight-inch slab for shops with a vehicle lift or heavy equipment
- Six-inch reinforced for RV pads and trailer parking
- Compacted aggregate base, thicker on clay subgrade
- Vapor barrier on conditioned shops, perimeter insulation where needed
Floor flatness for working shops
If you are putting a lift in or rolling toolboxes around, the floor flatness matters. We screed and float shop slabs to a tighter tolerance than residential work, and we plan the slope so liquids drain to a doorway or trench, not toward the workbench.
RV pads and trailer parking
An RV pad needs to handle the tongue weight of a loaded fifth wheel without spalling at the wheel chock. We pour them six inches thick, reinforced, with a slight slope for drainage and a broom finish for traction.
