Shed slabs and hot tub pads in Pittsburgh, PA
A small concrete pad is the kind of job big concrete companies turn down, but a shed on a bad base racks its doors, and a hot tub on a bad pad cracks. We will come out for an 8x10, build the same kind of base and do it properly. A concrete slab for a garden shed is one of the most common small jobs we pour.

Getting a truck to the back yard
Backyard pads are where access decides the price. If a truck can't get close, concrete comes in by buggy or by a small pump, and fences or gates may have to open up. On many Pittsburgh lots, a pad on a back slope needs digging on the high side and a form or short wall on the low side. Walk your yard from the street to the spot and measure the narrowest gate, because that is the first thing we will ask.
Hot tub pads
A filled hot tub can weigh three tons or more, plus people. It needs a level, reinforced pad at least 4 inches thick, and often 6, on a stone base. Check the tub maker's requirements before you pour, because some warranties depend on them. Plan the electrical at the same time, since it is easy to run conduit before the pour and hard to run it afterward.
Do you need a slab under a shed?
Not always. A small shed can sit on compacted stone with blocks or timbers. A slab makes sense when you will store a mower or heavy equipment, want a dry floor or have a shed that is large or built on site. A slab also stops rodents from getting under the floor. Check your township rules too, as many set size limits and setbacks for sheds.
Pole barn and workshop slabs
In a pole building, the posts usually go in first and the floor is poured after the shell is up. That protects the slab and keeps the weather off the finishers. For workshop slabs of any size, see our main concrete slabs page.
