Foundation Repair & House Leveling in Primera, TX.

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.
