Is there a typical soil resistivity for McAllen–Edinburg–Mission?+
No citywide value can represent a parcel, substation, route, or facility. Lower Rio Grande Valley sites can contain fine-grained alluvium, clay, silt, irrigation-influenced ground, and localized saline conditions. Extended heat makes current moisture and seasonal surface condition important at each station. 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 McAllen–Edinburg–Mission 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.
