Jet grouting, an integral technique in foundation reinforcement, involves the on-site mixing of soil with injected cement grout to create stabilized soil columns. These columns significantly improve the soil’s structural properties, increasing strength, and decreasing permeability. This makes them an excellent solution for reinforcing foundations, especially in scenarios where existing structures require additional support or where new constructions demand enhanced stability.
The process entails drilling a small-diameter pipe (typically around 4 inches) to the desired depth. Contractors then inject cement grout at high pressures (around 6,000 psi) through the drill pipe. As the pipe is rotated and withdrawn, it creates a circular column of reinforced soil. The diameter and positioning of these columns can be customized, providing tailored support for a variety of foundation reinforcement needs.
