New construction slabs, pier-and-beam foundations, over-excavated pads, and equipment slabs — designed for Panhandle caliche and clay expansion.
Call (806) XXX-XXXXA foundation in Amarillo isn't a Dallas foundation and isn't a Lubbock foundation either. The Panhandle sits on a mix of caliche caprock, clay-heavy topsoil, and pockets of Ogallala sand that don't behave like anything to the south or east. Get the design right and the slab lasts 100 years. Get it wrong — skip the sub-grade prep, miss the caliche layer, undersize the piers — and cracks show up before the first drywall goes on.
We work with the structural engineer of record on every foundation job — we don't guess loads and we don't skip the geotechnical review. If you don't have a soils report yet, we can recommend a local Amarillo geotech to pull borings and give you a design basis. On a house-sized foundation, that report costs $800–$1,500 and prevents six-figure remediation problems later.
On typical Amarillo suburban lots (Puckett Place, La Paloma, Greenways, the newer builds along Soncy) you're pouring a slab on 4–8 feet of expansive clay above the caprock. That clay swells with moisture cycling and slab-on-grade without post-tension will show settlement cracks in 5–15 years.
Post-tension slabs pre-compress the concrete via steel cables tensioned to ~33,000 lbs each, pulled after the concrete reaches 3,000 PSI (usually days 3–7). The compression pre-load means clay-swell tension has to overcome the pre-load before it stresses the concrete. In practice, post-tension slabs in Amarillo handle 30+ years of clay cycling with minimal cracking.
We work with the engineer on cable layout, chair heights, and stressing sequence. On a typical 2,400 sqft house slab, expect 40–60 cables running in two orthogonal directions.
Pier-and-beam makes sense in three situations:
Piers in Amarillo typically drill to 8–14 feet to bell out below active clay depth. Grade beams span pier-to-pier. Suspended structural slab or wood-framed floor system spans grade beams.
No matter what foundation type: vegetation stripped, topsoil removed from footprint, sub-grade compacted to 95% Standard Proctor at optimum moisture, moisture-conditioning if too dry to compact, 10-mil poly vapor barrier with taped seams and booted plumbing penetrations, insulation where energy code requires.
Both Potter County and Randall County require permits and inspections on new residential foundations. City of Amarillo Building Safety handles work inside city limits — plan review, footing inspection before pour, pre-slab inspection before concrete arrives. We coordinate the inspection calls; the GC or homeowner pulls the permit.
| Foundation type (typical 2,400 sqft) | Range |
|---|---|
| Post-tension slab | $22,000–$38,000 |
| Pier-and-beam (12-ft piers) | $45,000–$85,000 |
| Over-excavated + standard slab | $18,000–$32,000 |
We quote after we see the engineering set and walk the site.
Yes, for any structural foundation. Residential post-tension especially.
Post-tension is standard in Amarillo for anything on expansive clay.
Typically 8–14 feet to get below active clay. Design driven.
3–5 days after pour for framing lumber, 7+ days before heavy loading.
No. New pours only.
