The E&S Grounding Solutions Soil Resistivity Calculator is a professional-grade tool for analyzing Wenner four-pin field data, computing two-layer soil models, and preparing inputs for IEEE 80 grounding system design.
Key features include: Wenner apparent resistivity calculation from field measurements, two-layer soil model derivation using least-squares curve fitting per IEEE Std. 81-2025 Annex B, soil model export in CDEGS RESAP format, and step and touch voltage tolerable limit calculation per IEEE 80.
The calculator is designed for licensed Professional Engineers performing IEEE 80 grounding studies. It is available in Starter (free), Pro, and Firm subscription tiers. Pro and Firm tiers include unlimited projects, PDF report generation, and priority support.
