• Abstract:
  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, ; jetting time, and characteristics of deleterious materials.
