CHUM case study

Case History 3: Single hole test (SHUT)

This pile is bored and cast in place, with a diameter of 400mm (16") and 6m (19ft) long, with a single 40mm PVC access tube.

Casting was interrupted, and some soil collapsed into the hole.

It was tested a few days after curing.

A defect at -3.40m of about 20 to 30cm was easily detected using CHUM
