Is there a typical soil resistivity for Dallas–Fort Worth?+
No citywide value can represent a parcel, substation, route, or facility. Dallas–Fort Worth crosses Blackland Prairie, Cross Timbers, and developed urban corridors. Expansive clay, sandy or loamy zones, imported fill, and long summer drying periods can produce different apparent soil electrical resistivity along one electrical route. Field measurements must be tied to the actual array, location, spacing, orientation, and current condition.
Does Wenner electrode spacing equal test depth?+
No. Larger spacing generally samples a larger earth volume, but spacing is not an exact one-to-one depth. Layering, array geometry, site boundaries, and conductive features affect the apparent response.
What information is needed to scope a Dallas–Fort Worth survey?+
Send the site plan, survey objective, grounding or corrosion design request, proposed stations and spacings, final grading information, candidate line corridors, utility-clearance responsibility, access rules, schedule, and required report format.
Can Calicore mobilize outside California?+
Yes. Calicore performs project-based Wenner field programs throughout the United States when the station count, spacing, access, schedule, and mobilization are practical.
