This service is the critical first link in the construction engineering chain, capturing the raw physical data that structural engineers require to design safe, cost-effective foundations.From light residential developments to heavy civil infrastructure, geotechnical drilling converts subsurface unknowns into predictable, quantifiable engineering profiles.
Auger Drilling: Rapid, shallow-to-medium depth soil profiling in cohesive grounds.
Rock Core Drilling: Extracts intact, deep rock cores using diamond-tipped bits to evaluate structural integrity.
Disturbed Sampling: Recovered via split-spoon or auger cuttings for visual classification and sieve analysis.
Undisturbed Sampling (Shelby Tubes): Extracted via thin-walled tubes in clays to preserve structural properties for lab strength testing.
Rock Quality Evaluation: Logs recovered cores to calculate the Rock Quality Designation (RQD) percentage for weathering and fracturing.
