Shop Slabs, Garage Pads & Foundations in Conroe
The pad under your shop, barndo, or carport is the one part you can't upgrade later. Engineered thickness, turndown edges, and steel that matches what you're putting on it.
The Montgomery County slab boom
Drive any FM road out of Conroe — toward Willis, Montgomery, or Cut and Shoot — and you'll see what people move out here to do: metal shops, barndominiums, RV covers, and workshops on acreage the city can't offer. Every one of them starts as a slab, and the slab is the one component with no do-over. Steel building kits arrive with anchor-bolt patterns that assume a flat, square, correctly-cured pad; RVs and lifts assume thickness where their weight actually lands.

Ranges reflect thickness, turndown/beam design, steel spec, and how much dirt work the site needs. Written quotes are free and itemized — you'll see exactly what the pad includes.
What's under a slab that lasts here
- Dirt work first. Expansive clay means pads get built up with select fill and compacted in lifts — pouring on native gumbo is how slabs tilt.
- Turndown edges / grade beams where the structure loads sit, sized to the building — a steel building's columns don't get to sit on 4 inches of field pour.
- Steel that matches use: rebar grids for shops, heavier layouts where a lift or RV parks.
- Moisture barrier under anything that'll be enclosed — Houston-area humidity comes up through bare slabs and rusts everything you store on them.
- Anchor-bolt coordination with your building kit's drawings, so erection day doesn't start with a grinder.
Permits and setbacks, plainly
Outside city limits in unincorporated Montgomery County, permitting for accessory slabs is light — but floodplain rules along the San Jacinto and Lake Creek drainages are real, and inside Conroe or Montgomery city limits accessory structures have setback and permit requirements. We flag what applies to your parcel during the quote so the county never becomes a mid-project surprise.
