Metal Building Slabs & Foundations in San Antonio, TX

Slabs, piers, and footings poured to your steel supplier anchor bolt plan - so the building goes up the day the crew arrives.

Metal Building Foundations

Anchor Bolts Where The Plan Says

A metal building foundation lives or dies on the anchor bolts. Every column lands on a bolt pattern the steel supplier has already drawn, and if the bolts are out by half an inch the erection crew is standing around while somebody drills and epoxies - on your clock.

We work from the supplier drawings, set templates before the pour, and check the diagonals before the concrete goes in. Piers, footings, grade beams and the slab itself, poured for barndominiums, steel shops, ag buildings and equipment storage across the San Antonio area.

  • Anchor bolts set to the steel supplier template and verified
  • Piers, spread footings, and grade beams to the engineer drawings
  • Slab and footings poured monolithic or in stages to suit the build
  • Reinforcing sized for San Antonio shrink-swell clay
  • Underground plumbing and conduit sleeved before the pour
  • Coordination with your erection crew schedule

Metal Building Slab FAQ

Common Concrete Questions

What builders and owners ask before a steel building pour.

Yes, and we prefer to. Send the anchor bolt plan from your steel supplier. We build templates, set the bolts in the wet pour, and check the diagonals before we finish. Drilling and epoxying afterwards is a repair, not a method.
Usually yes, and often your steel supplier or the permitting authority will require stamped foundation drawings. We build to whatever the engineer specifies and can point you to engineers who do this work locally.
It depends on the soil, the building size, and the column loads. On the clay soils around San Antonio a lot of buildings do better on piers and grade beams. The engineer makes that call and we pour it either way.
Yes. That is a standard job for us - slab, footings, anchor bolts, and the plumbing and conduit sleeved in before the pour so nobody is cutting the slab later.
Concrete needs to reach design strength before steel goes up, which is normally 7 to 28 days depending on the engineer requirement. Tell us your erection date and we will schedule the pour to meet it.
