A complete 60 ft sonic boring with continuous five-foot runs, recovery, material descriptions, USCS classifications, groundwater, tooling changes, casing advancement, drilling response, and completion details.
BH-SD-01 Sonic Drilling Investigation represents a river-crossing geotechnical program in Cambridge, Ontario. The profile advances through fill, silty sand, soft to firm silty clay, sand and gravel, dense sandy silt till, and weathered shale.
The validation report records Passed status, 100% completeness, Good quality, an 85% confidence score, and no errors or warnings.
The first page records fill and silty sand over soft to firm silty clay, including lower recovery where cohesive material swelled during extrusion. The second page follows the boring through water-bearing sand and gravel into dense sandy silt till, where cobbles increased vibration and temporarily blocked the barrel.
The final page documents the transition to weathered shale, the change to a carbide bit, achievement of the 60 ft target depth, and pressure-grout abandonment. Together, the three sheets demonstrate a complete sonic-drilling record from mobilization through closure.
Download the files individually. The XML template and sonic-drilling log can be imported into WinLoG Version 6 and customized for geotechnical, environmental, infrastructure, and drilling programs.
Documents continuous subsurface recovery, stratigraphic changes, groundwater, difficult drilling conditions, and borehole completion.
Provides a structured record of runs, recovery, core-barrel changes, casing advancement, drilling response, obstructions, and production conditions.
Supports river crossings, transportation corridors, foundations, environmental investigations, and other programs requiring continuous cores.
WinLoG templates can be adapted for company standards and project-specific sonic programs. Headers, run intervals, sample columns, recovery, tooling, drilling observations, lithology, groundwater, and validation rules can all be customized.
