2021 7 31 Construction Techniques For Bored Piling In Sand Using. This paper is concerned with the use of polymer fluids for the construction of bored piles in silty fine sand, a situation which has been found to significantly increase the risk of soft toes and concrete contamination due to the settling of the suspended soil particles in the fluid.
2014 7 28 Solutions of synthetic water soluble polymers have been used for the construction of bored piles drilled shafts since the early 1990s. These engineered fluids are very different from conventional bentonite slurries but there is currently a serious lack of industry guidance.

Three 1.2 m diameter and 40 m long bored piles were constructed using three types of excavation support fluids, as follows: 1 water P1, 2 bentonite P2, and 3 polymer P3 .
