Slabs Matched to the Load
Concrete slabs are the simplest-looking job we do, and the one where planning shows most. A shed slab that is out of level makes the door stick. An RV pad poured too thin cracks under the tires. A workshop floor that slopes the wrong way puts water at the door every summer storm. With about 88% of Rio Rancho homes single-family detached, plenty of yards have room for a shed, a workshop, a camper or a boat, and each of those needs the right pad.
Common slab projects
- Shed and storage building pads. A level slab sized slightly larger than the building, with anchor bolts set if the building needs them.
- Workshop and detached garage slabs. Thicker floors with reinforcement, and slab edges thickened where walls will bear.
- RV, boat and trailer pads. HomeGuide's slab guide uses 200 to 700 square feet as the typical RV pad range; we size yours to the vehicle with room to walk all the way around.
- Equipment and AC pads. Small slabs for mechanical units, generators and water tanks.
- Hot tub and gazebo pads. Reinforced slabs for concentrated weight.
Thickness, base and steel
Most residential slabs are 4 inches thick. Heavier uses step up: 5 to 6 inches for RVs and trucks, with thickened edges where loads concentrate. What sits under the slab is just as important as the slab. We remove topsoil and soft material, then place and compact gravel so the slab has uniform support. Rebar or mesh is lifted on chairs into the middle of the slab; steel left sitting on the dirt does little to hold cracks closed.
For slabs that will sit under a building, a vapor barrier under the concrete can help keep ground moisture out of stored items and finished floors. We talk through whether your project needs one.
Ground that settles when wet
The New Mexico Bureau of Geology describes collapsible soils that compact and drop after they get wet, and notes that housing developments from Velarde to Las Cruces have been affected. Its advice for developed areas is to keep water out of the ground with xeriscaping, downspouts and runoff control. For a slab, that means grading the surrounding ground away from the pad, keeping roof runoff off it, and not running irrigation right against its edges. If a lot shows signs of past settlement, we will point it out before we pour.
Permits and placement
A bigger slab, especially one that will carry a building, may need a permit, and setbacks from property lines can apply. Your HOA may also have rules about sheds and RV parking. We check the requirements for your address and help you place the slab where it will drain well and be easy to reach.

National ranges from HomeGuide's concrete slab cost guide. Rio Rancho prices depend on size, thickness, base depth, access and removal. Your written estimate is the price.
How a Slab Gets Built
1. Site and size
We confirm the size, location, use and drainage, and check any permit or HOA rules.
2. Excavate and compact
Soft soil is removed and a gravel base is compacted and leveled.
3. Forms and steel
Forms are set to grade, reinforcement is placed and anchors or vapor barrier go in if needed.
4. Pour and cure
The slab is poured, finished, jointed and cured before any building or load goes on it.
Concrete Slabs Questions
How much should a 20x20 concrete slab cost?
For a plain 400-square-foot slab, HomeGuide's national range is $2,400 to $4,800 installed. Depth, base work, truck access and any old concrete to remove decide where in that range a job falls.
How thick should a shed slab be?
Most sheds sit fine on 4 inches. Heavy buildings, shops full of tools, or anything a vehicle will drive into should be deeper, with thickened perimeter edges.
Do I need a vapor barrier under my slab?
Under an enclosed building, where ground moisture could reach stored items or flooring, a vapor barrier makes sense. Open pads for RVs or AC units generally do without one.
How long before I can put a shed on a new slab?
Light buildings can often go on after about a week. For heavy buildings or vehicles, waiting closer to the full cure of about a month is safer. We give you a date for your slab.
