To achieve cleaning once drilling is complete, a cleanout bucket is typically used to remove any material unsuitable for end bearing support. Bottom inspection is then performed, often by lowering a camera down the bore hole, a procedure that gives a rough idea of the thickness of any debris left at the bottom. To improve the inspection method, 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.
