Bored Piling Technique. Bored pile deployment begins by drilling a vertical opening into the earth, using a bore piling tool. In order to extract the soil and rock, the device can be equipped with specially built drilling equipment, buckets, and aces. Piles can be drilled-in up to 60 meters deep and up to 2.4 meters in diameter.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.
