Shed pads, RV pads, garage floors, room addition foundations, ADU slabs. Engineered for San Tan Valley's expansive soil and poured to spec — every project, every phase.
From a single shed pad to a full ADU foundation, we handle the pre-pour site prep, forming, reinforcement, and finishing. Our crews work residential and light-commercial slabs across San Tan Valley — sized, reinforced, and cured to match what the structure on top of them will actually need.
Six pours we run most weeks in San Tan Valley. Every one starts with soil prep and ends with a documented finish — no shortcuts on the work underneath.
Pads for storage sheds, workshops, and detached outbuildings. Sized to the structure, with a slight overhang past the footprint to shed water.
Heavy-duty slabs for RVs, fifth wheels, and trailers. Thicker pours with reinforced rebar to handle point loads from jacks and tires.
New garage slabs and garage extensions tied into existing foundations. Vapor barrier under, broom finish or smooth trowel on top.
Monolithic slabs or stem-wall foundations for room additions. Engineered to match the existing structure's load path and finish elevation.
Small reinforced pads for HVAC condensers, pool equipment, generators, and mini-splits. Level, square, and code-compliant clearances.
Foundations for accessory dwelling units and casitas. Full pre-construction coordination with your framer, plumber, and electrician.
Shed pads typically pour at 4 inches with #3 rebar on 18-inch centers. RV pads step up to 6 inches with #4 rebar and a thicker base course. Garage and ADU slabs pour at 4 to 6 inches over a 6-mil vapor barrier, with rebar or welded wire mesh sized to the load.
San Tan Valley's expansive clay soils move when they get wet and shrink when they dry — which is why every slab we pour starts with the prep underneath. We over-excavate, bring in a compacted granular base, and confirm subgrade compaction before a single form board goes down. The pour is the easy part. The base is what decides whether the slab holds for thirty years or cracks in three.

When overnight lows drop near 40°F, we preheat mix water and aggregates, add an accelerating admixture to keep hydration moving, and cover the fresh pour with insulating blankets through the first night. We also watch the forecast and schedule pours during daytime highs, never into a storm front. Done right, a January slab cures every bit as strong as a June one.
For straightforward shed pads, RV pads, and equipment pads we can usually be on-site inside two to three weeks of the signed estimate. Room additions and ADU foundations need permit and engineering coordination, so plan on four to six weeks from go-ahead to first pour day.
We pour year-round. In summer we start at first light to beat the heat and use retarders to slow set time. In winter we use warm mix water, accelerators, and insulating blankets on overnight lows under 40°F. We won't pour into an active storm or onto saturated subgrade.
Detached shed pads under the county threshold and small equipment pads usually don't require a permit. Anything structural — room additions, ADU foundations, garage extensions — does. We pull the permit, coordinate inspections, and hand you signed-off paperwork at close-out.
Concrete reaches roughly 70% of its design strength at seven days and 90% by twenty-eight days. For framing on a residential slab we typically green-light at seven days. For heavier loads — masonry, RVs, vehicles — wait the full twenty-eight.
It depends on the load. Standard shed pads get #3 rebar on 18-inch centers. RV pads and garage floors step up to #4 rebar on 16-inch centers or welded wire mesh, sometimes both. Room addition and ADU foundations follow the structural engineer's drawings exactly — we don't substitute spec.
We handle it. Over-excavation, base course, compaction, vapor barrier, and form work are all part of our scope. Given how much San Tan Valley's expansive soils move, leaving the prep to someone else is the single most common reason slabs fail early.
Tell us the application, the rough dimensions, and the location in San Tan Valley. We'll come walk the site, confirm the soil prep needed, and come back with a fixed estimate.
Slab work usually ties into one of these — and we run all of them in-house.
New driveway pours, extensions, and replacements. Reinforced and finished to handle daily vehicle loads in San Tan Valley heat.
Light-commercial slabs, equipment pads, and small-format foundations for local businesses and contractors.
Crack repair, slab leveling, and resurfacing for existing pads that have shifted or scaled in the desert soil.
