Evaluating Base Cleanliness of Drilled Shafts using SQUID Testing Device by GRL Engineers, Inc.

An important part of bored pile construction is the cleaning and inspection of the bottom of the hole prior to the placement of reinforcement and concrete. GRL Engineers utilize a Shaft Quantitative Inspection Device (SQUID) to measure force and displacement at the bottom of a drilled hole to quantitatively assess the cleanliness or the debris thickness of the excavation bottom.
