Foundation Repair for Structural Engineers: We Install to Your Spec
Foundation repair for structural engineers works best when the roles are clean: you hold the engineering judgment, and we hold the shovels. When you've designed a repair — a stamped plan with a pier type, a count, a layout, and target depths — you need an installer who builds exactly that, documents that they did, and doesn't override the engineering to suit itself. That's the crew we are. We install your plan to spec, we provide field measurements and as-built documentation so you can confirm the repair matched the design, we coordinate the permit against your drawings, and we work cleanly alongside independent engineers as a matter of routine. You design; we install. We handle residential and light commercial work — and for a larger or multi-story structure, an engineer's involvement is exactly the coordination we expect.
YOUR LANE
The design
- The engineering judgment and the stamped design
- Pier type, count, spacing, and target depth
- The load path and the acceptance criteria
- Any design change if a field condition needs one
OUR LANE
The installation
- Install exactly to your drawings — no substitutions
- Excavate, press, and set piers where the plan shows
- Log depth, refusal, and elevations at each location
- Deliver as-builts, coordinate permits, restore the site
We build your design, not our own
The reason an engineer keeps a reliable installer on hand is that the installer respects the drawing. When you hand us a stamped plan, we install the pier type you specified, at the count and spacing you laid out, to the depth your design calls for — we don't quietly swap in a different pier system, re-space the layout to save a day, or value-engineer your count without telling you. Our core methods are the same ones detailed on our steel pier and slab repair pages, but on your job they're driven by your drawings, not our defaults. Build to the design you signed, and document that we did — that's the job.
Field measurements and as-built documentation
An engineered repair isn't finished when the last pier is set — it's finished when you have a record that the installation matched the design. So we produce it. As we work, we log the field data you need to close out your file and stand behind the repair.
THE AS-BUILT RECORD YOU GET
- A pier installation log — every location, the depth reached, and the driving pressure or refusal there
- Before-and-after floor elevations tied to your benchmark and acceptance criteria
- Site photos of the excavation, the piers, and the grade beam or footing they bear on
- Permit and inspection sign-offs against your stamped drawings, where required
- A clean package that confirms the installation matched the design — not a marketing summary
Elevations tied to your benchmark
Because your acceptance criteria usually turn on how far the floor comes back, we measure elevations against your benchmark — before we start and after we set — and hand you the numbers rather than a verbal "looks level." The same crews that level floors on our own jobs run those readings to your target, not to a rule of thumb, and we tie the before-and-after into the as-built package. If your plan specifies a partial lift or a hold-at-position rather than a full correction, we install to that call and record it — the design decides the target, and we install to it.
Permits, and access when you need to observe first
Where the jurisdiction requires a permit and inspection for the foundation work, we pull it and coordinate the inspections against your stamped drawings — or work under an existing permit if the project already has one under a GC or owner. And when you need to see under the slab before finalizing a design — grade beams, plumbing penetrations, voids, moisture, soil — we hand-dig a clean, shored engineer-access tunnel to your specification and backfill afterward. That access work is scoped on our under-slab tunneling for structural engineers page; it complements this one — that page is about opening the ground so you can observe, this one is about installing the repair you then design.
We don't override the engineering
Here's the part that matters most to an engineer staking a stamp on the outcome: we stay in our lane. We don't tell the homeowner your design is overkill, we don't second-guess your pier count on the jobsite, and we don't substitute our judgment for yours. If we hit a field condition worth your attention — refusal shallower or deeper than expected, an obstruction, a soil surprise — we stop and bring it to you, and the call stays yours. We're comfortable working alongside independent engineers precisely because we know where the line is: the design is your responsibility, the installation is ours, and we don't blur the two.
Where we work
Motmot covers the full I-35 corridor — San Antonio, New Braunfels, San Marcos, Kyle, Buda, Austin, and Georgetown — from offices in San Antonio and San Marcos. Beyond installing your repair, we can tunnel under-slab access for observation or plumbing work, and correct the drainage that drives movement when your scope calls for it. Every job produces the documentation package your file needs. See how we partner across the trades on the industries we serve, including general contractors and commercial work.
