What this means if you own property in 75062: "Shrink-swell" describes soil that expands when wet and shrinks when it dries out — the actual mechanism behind cracked slabs, sticking doors, and uneven floors, not just a label. Only 6% of this ZIP's rated area falls in the High or Very High shrink-swell range — this specific ZIP looks more stable than many others in the metro, though a site-specific inspection is still the only way to know your exact lot.
Likely repair approach for this soil profile
Mudjacking/slabjacking or minor releveling, if any repair is needed at all
This ZIP's soil profile leans low-to-moderate shrink-swell, so foundation movement here is less likely to be driven by chronic clay expansion. When settling does happen, it's more often addressed by pressure-grouting under the slab to relevel it — a faster, less invasive repair that works because the soil isn't actively cycling underneath it the way expansive clay does.
This is general engineering guidance based on this ZIP's real soil composition above, not a record of repairs actually performed here — the right method for any specific property still depends on a site inspection, foundation type, and the actual damage observed.
Current drought conditions — U.S. Drought Monitor
No significant drought is affecting Dallas County right now. That's relevant too — the shrink-swell movement described above is driven by wet/dry cycling, and without an active drought, this ZIP's soil composition (not current weather) is what's actually driving any foundation risk here.

Source: USDA Natural Resources Conservation Service, SSURGO soil survey, area-weighted per ZIP via intersection with Census TIGER/Line ZCTA boundaries. Shrink-swell class is derived from each soil component's Linear Extensibility Percent (LEP), the standard USDA-NRCS expansive-soil indicator. This describes the ZIP overall — soil composition can still vary within a single property; a site-specific inspection is the only way to know conditions at a specific address.
