Test Holes

Test holes are exploratory excavations or drilled openings created to investigate subsurface soil and rock conditions at a specific location. They are undertaken during site investigations to obtain visual confirmation of ground conditions, collect samples, assess groundwater, and inform geotechnical and structural design.
