Jet grouting, a versatile in-situ procedure, combines soil and injected cement grout to form robust cement-stabilized soil columns. Through stringent quality control, the stabilized soil demonstrates increased strength and reduced permeability, making it an ideal engineered product for foundation support and groundwater control. Notably, jet grouting finds typical applications in underpinning existing structures and creating cutoff walls for dependable excavation support.
The process entails drilling or jetting a small-diameter pipe, typically around 4 inches, to the desired treatment depth. Upon reaching the target depth, skilled contractors inject a high-pressure neat cement grout, typically around 6,000 psi, through ports at the pipe’s bottom end while rotating and withdrawing it. This creates a circular column of treated soil. By adjusting the rate of withdrawal, the diameter of the jet grout columns can be modified. These strategically positioned columns provide essential vertical support or can be overlapped to form walls or barriers, effectively impeding the horizontal movement of weak soil and groundwater.
