Abstract
15. SUPPLEMENTAL NOTES Presented in this report are results of a laboratory investigation designed to examine the effectiveness of water jetting as a means for mitigating defects in drilled shaft foundations. The primary objective of this research was to establish an empirical relationship between water jetting pressure and the removal of deleterious materials from drilled shaft defects (e.g. low strength concrete, slurry mix concrete, semi-cemented sand, loose soil, etc.). The principal research activities conducted as part of this study included: a search of the existing literature and interviews with foundation contractors to identify the current state of water jet technology; and, a parametric laboratory investigation to examine water jetting effectiveness in relation to jetting pressure, standoff distance,
