Underslurry Piles

[info]Bored Piles are drilled under a head of slurry – either bentonite or polymer to mitigate collapse. Underslurry piles are ideal for deep foundations up to 68 meters deep using slurry to support the earth as the pile is being drilled.[/info]

The diagram below shows the standard procedure of casing installation, excavation, cleaning of the slurry; then installing the reinforcement cage, pouring the concrete and extracting the casing.
