Action House Leveling is based in Mercedes, just minutes from Primera. You get same-day inspections, a crew that knows the local soil profile, and reinforced concrete piers engineered for the ground under your slab.
Primera shares the Harlingen clay association with neighboring Harlingen and Combes — fine smectitic Sodic Haplusterts with PI 45–60 and very high shrink-swell potential.
The town sits on a slight rise relative to the surrounding agricultural land, which means runoff tends to push water toward homes on the downhill sides during rain events, then drain away during dry spells.
That recurring saturate-and-drain cycle is what hurts Primera slabs.
Sodium content in the irrigated horizons is meaningful enough that bare steel piers corrode within 10–15 years; reinforced concrete piers driven through the active expansive zone are the right call.
Slabs on the downhill side of any Primera property get repeatedly wetted by rain runoff — they swell unevenly and crack along the wet edge.
1950s–70s ranches in Primera mirror the Stuart Place pattern: shallow slabs, minimal rebar, corners that crack by year 30.
Older raised homes here battle chronic ground moisture from the surrounding irrigated fields.
Mature mesquite and live oak near older Primera slabs lift corners by 1–2" as the root mass expands.
Yes — we work the Harlingen-Primera corridor weekly out of Mercedes.
All of 78552 — north toward Hwy 77, FM 508, and the Stuart Place border.
Yes. Elevation gear, perimeter walk, written report — no charge.
Yes. Sill replacement, beam sistering, and concrete pad resets — common on the older homes here.
