Most foundation contractors work from a national playbook. The same methods, the same sales pitch, the same repair sequence — applied regardless of what the soil is actually doing. That works fine in places with predictable geology. New Mexico is not one of those places.

The state spans sixteen geologically distinct basins. Expansive clays that heave upward in wet cycles. Collapsible soils that compress suddenly when saturated. Karst dissolution voids beneath the surface. Gypsum deposits that dissolve over time. Each formation has its own failure mode, its own diagnostic requirements, and its own appropriate response.

The difference between heave and settlement — soil pushing up versus soil pulling down — determines everything about how to respond. Getting that diagnosis wrong is consequential. We built our diagnostic standard around this: heave until proven settlement. The soil tells you what it's doing. You have to know how to read it.
