From North McAllen master-planned subdivisions to historic homes near downtown, Action House Leveling has been stabilizing McAllen, TX foundations for over 20 years. Reinforced concrete piers, real engineering, and a lifetime transferable warranty.
McAllen sits on the Hidalgo–Raymondville clay loam association — fine, mixed, hyperthermic Typic Calciustolls and Haplusterts laid down on the old Pleistocene Lissie/Beaumont terrace north of the modern floodplain.
Plasticity index typically runs 25–45, lower than the delta clays in Cameron County but still firmly in the 'high shrink-swell' band per NRCS.
Subsurface caliche layers (CaCO3 nodules) at 3–6 ft are common across north McAllen and Sharyland and create perched water conditions: rain infiltrates fast through the upper loam, hits the caliche, and spreads laterally under slabs instead of draining.
That's why neighborhoods around 10th Street and north of Trenton see edge heave even when surface drainage looks fine.
South of Business 83, the soil grades into older alluvial clay with PI closer to 40 and a deeper active zone (8–10 ft).
New subdivisions on engineered select fill consolidate for 5–10 years over either profile, which is why we engineer pier depth to the specific soil column under each home rather than using a one-size depth.
North McAllen and Sharyland subdivisions built on imported fill drop corners as the fill consolidates.
Newer master-planned communities use post-tension slabs that need careful pier placement to lift safely.
1950s–70s homes around 17th St and downtown were poured shallow — cracks open as the clay cycles wet and dry.
Stair-step cracks and gaps at window corners are some of the first signs Hidalgo clay is moving under your slab.
We dispatch to McAllen daily from our Mercedes yard — most inspections happen within 24–48 hours.
Yes — North McAllen, Sharyland, Las Palmas, downtown, south side, and out to Bentsen Palm. Every ZIP, every neighborhood.
Absolutely. Many North McAllen builds use post-tension slabs and we have the engineering and equipment to lift them safely without damaging the cables.
Yes. We'll take elevation readings, walk the perimeter, and give you an honest written report at no cost and no pressure.
