Littleton Shed Pad Contractors

Nobody agonizes over a shed pad until they start pricing one. Then the forks in the road arrive all at once. Concrete or packed gravel. Match the building footprint or run wider. Bolt the walls down or let the thing sit there. Pour before you buy or buy before you pour. None of those are trick questions, but the answers lean on each other, which is what makes a simple pour feel complicated.

Our job at the estimate is to sort them for your yard. Go Denver Concrete works across the Front Range, we carry license, bond, and insurance, and there's a structural engineer in house for the outbuildings that turn out to be more building than shed. Most don't. Most are one morning of concrete and a decision list you can knock out in ten minutes.

Gravel or concrete: where the line actually falls

A compacted gravel bed under a small resin storage box is fine. Nothing rolls in and out, nothing heavy sits in one spot, and if it shifts a little nobody cares. The line gets crossed the moment the building has a wooden floor, a door you use weekly, or contents worth protecting. Gravel lets moisture up, gives mice a way in, and wanders under point loads.

Concrete answers all three, and it does one thing gravel never will: it gives you an anchor. A slab holds bolts, and bolts hold a building through the wind that comes off the foothills. That matters more on exposed lots out toward Ken Caryl than in a sheltered yard in Columbine, though we've seen walls racked in both. If the building will still be there in ten years, pour it.

Footprint, apron, and where the water lands

Pour the slab to the wall line, not past it. A margin of exposed concrete around the outside catches every drop of roof runoff and holds it against the bottom of the siding, and that's how a shed rots from the ground up. The exception is out front. Add a real apron at the doors, pitched away, wide enough to swing a mower through without dropping a wheel off the edge.

Then look uphill. On sloped ground west of town, whatever crosses that yard will meet your new slab, so we cut a shallow diversion above it or set the pad a touch high and feather the grade back. On the flats it's the opposite problem: water arrives and has nowhere to go. Both get solved with dirt work before concrete shows up.

Pad first or building first

What we build into an outbuilding pad

• Footprint squared and staked off your building's real plate dimensions
• Topsoil and organics stripped, soft spots dug out and replaced
• Compacted road base under the whole slab, placed in lifts
• Thickened edge where the walls bear, steel through the middle
• Anchor bolts cast wet at the plate locations on your drawings
• Pitch away from the doors and a diversion above on sloped lots
• Broom finish for footing when the surface is wet
• Spoils hauled off and the surrounding grass put back in shape

Unheated buildings, frost, and the month to book

An unheated shed puts no warmth into the ground, so the soil below freezes the same way the open yard does. A light garden building rides that out on a thickened-edge slab over good compacted base, and the base does the real work by draining instead of holding water where it can freeze. Heavier structures, or anything with equipment and swinging doors, get frost-depth footings and an engineer's eyes first.

Booking comes down to workable ground. April through October runs easy, and late summer is the sweet spot: the pad is cured and waiting before delivery season slows. Winter pours are possible with warm mix and blankets, though a small slab sheds heat fast and we'd rather put you on the spring calendar. Give it seven days before the building goes on, and skip ice melt the first winter.
