Geotechnical Soil Interpretation Reference
The geotechnical report is the single most important document for a trenchless design, but the parameters that matter to a driller are not always the ones highlighted in the log. This reference explains how to read boring logs and USCS soil classifications through an HDD lens — which properties drive drillability, hole stability, frac-out risk, and pull force.
It is grounded in ASTM D2487 (Unified Soil Classification System) and ASCE MOP 108.
