Is there a typical soil resistivity for San Jose–Silicon Valley?+
No citywide value can represent a parcel, substation, route, or facility. Silicon Valley has dry summers and seasonally wetter winters. Santa Clara Valley alluvial fans contain changing proportions of sand, gravel, silt, and clay, while developed sites often include multiple generations of engineered fill. 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 San Jose–Silicon Valley 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.
