JGP (Jet Grout Pile)
Jet Grouting is a technique of mixing in-situ soil with the energy of high-pressure jet of slurry. A small-diameter rod drills down to the improvement bottom. Then the rod, while being withdrawn, jets the cement-base slurry and air to produce an improved column. The compressed air and hardening agents which usually consists of cement and water are jetted with a high-pressure energy and discharge rate from jet monitors in horizontal direction to construct larger diameter soil-cement columns.
