Soil Boring

In Plain English

Drilling a hole in the ground to collect soil samples and determine what's underground before designing foundations.

Definition

A subsurface investigation technique where a drill rig advances a borehole into the ground to retrieve soil samples and perform in-situ tests at various depths. Soil borings are performed by geotechnical engineers to determine soil stratification, bearing capacity, groundwater conditions, and other properties needed for foundation design. The data is summarized in a geotechnical report with boring logs.

Example

Twelve soil borings were advanced to 50-foot depth across the site to characterize subsurface conditions for the structural engineer.
