Importance of Geotechnical Investigation in HDD & Trenchless Installations
See the critical role of geotechnical investigations in both Horizontal Directional Drilling (HDD) and trenchless installations. These investigations provide essential information on soil types, soil consistency, density, and groundwater conditions, which are crucial for both design and construction decisions. Utilizing existing data and new boring logs, engineers can make informed risk assessments rather than relying on guesswork. The segment also explains how geotechnical reports, typically presented as charts, break down the different soil strata encountered during drilling. These charts help engineers and contractors understand the varying subsurface conditions, such as superficial deposits, weathered rock, and core rock, across the drilling path, enabling them to choose appropriate tooling and techniques for each section of the drill.
