Shop and garage slabs
Reinforced slabs with the thickness and PSI matched to vehicle and equipment loads.
Placed & Finished
Concrete Slab Installation in San Antonio, TX
Shop floors, garage additions, RV pads, and equipment bases all live or die on base prep and joint layout. We build the pad first, then place a slab thick enough for what you actually intend to park on it.

What's Included
Slabs work we handle across the San Antonio metro
Equipment and generator pads
Anchor-bolt layouts and embeds set from your supplier's template, not eyeballed.
RV and trailer pads
Heavy-duty pads with approach transitions so the edge does not spall under a loaded axle.
How We Build It
The details that decide whether San Antonio concrete lasts
Joint spacing done right
Control joints get cut on a spacing tied to slab thickness, usually within 12 hours of the pour. Skipped or late joints are the single most common reason a young slab cracks in a random line.
Base and compaction
Select fill placed in lifts and compacted to target, then proof-rolled. Nothing gets poured on soft ground.
Overview
Concrete Slab Installation in San Antonio, TX
A concrete slab is the base that everything else sits on — a workshop, a metal building, a garage addition, an RV, a storage shed, a generator, or a stack of equipment. It's a simple-sounding project that goes wrong more often than any other type of flatwork, almost always because the ground under it wasn't prepared to carry the load it ended up holding.
We build slabs for homeowners, small businesses and builders throughout the San Antonio area. That includes shop and garage floors, metal building pads, shed and playset slabs, RV and trailer pads, dumpster pads, generator and A/C equipment bases, and pads for storage containers.
The right slab for a lawnmower shed and the right slab for a lift in a shop are not the same thing. Before we quote, we ask what's going on it, what's going to roll across it, and whether anything needs to bolt down to it — because thickness, reinforcement, embeds and joint layout all follow from those answers.

Why It's Worth Doing Right
Why a Properly Built Slab Is Worth the Difference
It carries the load you actually have
A slab sized for real equipment weight won't crack under a loaded trailer tongue, a jack stand or a pallet of material.
A flat, workable floor
Screeded and floated flat means cabinets sit level, a lift plumbs up correctly, and rolling toolboxes don't drift across the room.
It keeps moisture and pests out of your building
A slab with proper elevation and drainage keeps water from running into a shop instead of around it, and removes the dirt floor pests like.
Anchor points that are actually in the right place
Anchor bolts and embeds set from your building or equipment template mean the structure lands where it's supposed to on install day.
Cleanable and durable
A finished concrete floor sweeps and washes clean, takes oil and chemical spills better than dirt or gravel, and can be sealed or coated later.
It adds usable, permanent square footage
Once the pad is there, a shop, carport or building can go up on it now or years from now.
Is This You?
When Homeowners and Businesses Need a New Slab
- Putting up a metal building, shop, carport or detached garage
- Setting a storage shed, playset or greenhouse on something better than dirt or blocks
- Adding an RV, boat or trailer pad so vehicles aren't parked on the grass
- Installing a generator, A/C unit, water softener or other equipment that needs a level base
- Replacing an old garage or shop floor that's cracked, sunken or crumbling
- Creating a dumpster or delivery pad at a commercial property
- Expanding a work area so equipment isn't sinking into the yard after rain
- Converting a gravel or caliche area into a hard, clean working surface
What to Expect
How We Build a Slab
01 Talk through the use
We start with what's going on the slab — building size, equipment weight, vehicle traffic, anchor requirements — because that sets everything else.
02 Site visit and written estimate
We check access, elevation and drainage on site, then send a written price that includes dimensions, thickness, reinforcement and any base work.
03 Clear, excavate and build the pad
The area is cleared and cut to grade, and base material is placed and compacted in lifts. Soft ground gets dug out and rebuilt instead of poured over.
04 Forms, steel and embeds
Forms are set square and to elevation, reinforcement is tied and chaired, and anchor bolts or sleeves are laid out from your supplier's template.
05 Pour and finish
Concrete is placed, screeded and finished to the texture that fits the use — smooth trowel for an enclosed shop floor, broom finish for anything exposed to weather.
06 Joints, cure and handoff
Control joints are cut on a spacing matched to the slab thickness, the slab is cured, and we walk it with you and confirm dimensions and anchor locations.
Worth Knowing
Concrete Slabs for Sheds, Garages and Other Structures
The most useful thing you can do before calling for a slab estimate is find out what the structure needs. Metal building suppliers and shed manufacturers usually publish a foundation requirement — footprint dimensions, anchor bolt pattern, sometimes an edge thickening detail. Handing us that document up front removes almost all of the guesswork.
Slab size is the second thing worth thinking about. A slab poured exactly to a building's footprint leaves no room for a door swing, a step out, or a mower to sit beside the building. An extra foot or two of apron on the entry side is cheap while the forms are already set and impossible to add neatly later.
Details that come up on nearly every slab project:
- Anchor bolt layout — set from the actual template, not a dimension from memory.
- Edge thickening or a turned-down edge where a wall or building load lands.
- Slab elevation above surrounding grade, so water sheds away instead of running under a door.
- Sleeves for electrical, air lines or plumbing that need to come up through the floor.
- Whether you'll ever coat or polish the floor, which affects how we finish and cure it.
Service Area
Slab Work Throughout the San Antonio Metro
We pour slabs across San Antonio and out into the surrounding communities — Boerne, Bulverde, Helotes, Schertz, Cibolo, Converse, New Braunfels, and rural properties around Bexar County.
On acreage properties outside the city, access is often the biggest variable. Getting a concrete truck to a back pad without tearing up a yard or getting stuck takes planning, and sometimes a buggy or a pump instead of a direct chute pour. We sort that out during the site visit so it isn't a problem on pour day.
Ground conditions vary a lot across the region — some sites hit limestone close to the surface, others are deep clay that moves with moisture. Both affect how the pad gets built underneath the slab, which is why we look at the actual dirt rather than pricing off a square footage number over the phone.
Questions
Concrete Slab Questions
How thick does my slab need to be?
It depends entirely on the load. A shed pad, a garage floor and a pad for a loaded trailer are three different specs. Tell us what's going on it and we'll put a thickness and reinforcement recommendation in the written estimate.
Do I need rebar or is wire mesh enough?
That depends on the slab's use and thickness. Rebar tied on chairs is standard for slabs carrying vehicles or building loads. Whichever we spec, it gets listed in your estimate so you know what's actually going in the slab.
Can you pour a slab for a metal building I already bought?
Yes. Send us the manufacturer's foundation drawing or anchor bolt template and we'll build the slab to those dimensions and set the anchors accordingly.
How long before I can build on the new slab?
Concrete continues gaining strength after finishing, and the wait before setting a structure depends on the mix, thickness and weather. We give you a specific timeline for your slab at the end of the pour.
Can you pour a slab where the ground slopes?
Yes, though it usually means cut-and-fill work, retaining the high side, or forming a raised edge. We measure the fall during the site visit and include whatever earthwork the site needs in the estimate.
Will a slab crack?
Concrete relieves stress by cracking somewhere. Control joints cut at the correct spacing, on time, direct that into a straight line at a joint instead of a random crack through the field of the slab.
