Garage Slabs, Shop Floors and Pads Poured to Plan

A concrete slab in Billings, Laurel, Lockwood and across the Yellowstone Valley is the floor everything else sits on: the garage, the shop, the pole barn, the pad the camper parks on all winter. We form and pour new slabs and pads for homes and businesses across the valley, sized for the space and thickened for whatever will actually sit or roll on them.

This is new-pour work. When an existing pad is cracked through or has settled out of level, the fix is removal and replacement, because we do not jack or level concrete. Slab work also travels well with the rest of the flatwork, so one visit can cover a driveway and the walks and steps around it.

Garage Slabs and Shop Floors

A garage or shop floor takes point loads a patio never will: jack stands, a floor jack, a loaded trailer tongue, a rolling toolbox parked in one spot for years. Thickness and base carry all of that, so those slabs get poured heavier than exterior flatwork, with the edges thickened where walls and door tracks bear on them.

Finish matters more indoors. A shop floor gets a smoother, harder surface so casters roll and a broom actually cleans it, while an exterior pad gets a broom finish for grip in snow. We pitch a garage slab toward the door so meltwater running off a truck leaves the building instead of pooling at the back wall.

RV Pads, Shed Pads and Parking Pads

An RV parked on gravel sinks its jacks, and the tongue jack finds the soft spot every single time. A concrete pad ends that argument. We size the pad to the rig with room to walk around it. The pour gets the thickness the axle weight calls for, and a grade that sheds water instead of holding it under the tires.

Shed and outbuilding pads are smaller jobs with the same rules. Compacted base first, a square and level pad, and edges that hold up when a mower or a loaded wheelbarrow rolls off them. Extra parking pads beside an existing driveway are common work too, formed to tie into what is already there.

What Makes a Slab Last in This Climate

Freeze-thaw is the local test, and it is a hard one. Water gets into a slab or under it, freezes, expands, and pries the concrete apart from the inside. Exterior pours get air-entrained mix so freezing water has room to move, a compacted base that drains, and control joints placed where the slab wants to crack anyway.

The base is where a pad is really won or lost. Soft ground under one corner puts the whole slab in tension, and that is where the crack shows up two winters later. We grade and compact before the forms go up, then give the pour a real cure. Where a pad is already past that point, the answer is tear out and repour, starting with a free look at what you have.

How much does a concrete slab cost in Billings?
Square footage sets most of it, then the thickness the load calls for, how much base work the ground needs, access for the truck, and tear-out if an old pad is coming out first. We price it from a free in-person look and put the number in writing.
How thick should a garage slab or shop floor be?
It depends on what lives on it. A slab holding passenger vehicles is one spec; a shop floor taking equipment, a lift or loaded trailers wants more thickness and thickened edges. Tell us what will park and roll on it and we will spec the slab at the estimate.
Do you raise or level a sunken slab?
No. We do not do mudjacking or slab leveling. A pad that has settled has a base problem underneath, and pumping material below it treats the symptom. We remove the failed slab, rebuild and compact the ground, and pour a new pad that sits flat because what is under it is right.
Can you pour a pad for an RV or a shed?
Yes, both are regular work. RV and camper pads get sized to the rig with walking room, poured to the thickness the axle and jack loads call for, and graded so water drains off. Shed and outbuilding pads get the same base prep at a smaller scale.
How long before we can park on a new slab?
Foot traffic after a day or two, vehicles after about a week, and the concrete keeps gaining strength for roughly a month. We go over the timing for your pour and mix at handoff. Call (406) 717-4103 and we will come look at the spot.
