Jet Grouting
Jet grouting is a ground improvement technique that modifies the geotechnical properties of the in-situ soil. This method injects high-velocity jets of grout (or sometimes air or water) into the soil, which breaks up the soil structure and mixes it with the grout to create a more stable, cemented composite material known as ‘soilcrete’.
The process of jet grouting involves drilling down to the required depth and then injecting the grout through a rotating monitor. This method can be tailored to suit various soil conditions and project requirements by adjusting parameters such as the grout pressure, the rotation speed of the drill, and the rate of withdrawal of the injection rod.
Jet grouting is a versatile solution used in various applications:
- Underpinning Foundations: It is commonly used to stabilize existing foundations and other structures, enhancing the load-bearing capacity of the soil underneath.
- Waterproofing: It creates barriers for subterranean water control, ideal for constructing underground walls, tunnels, and to prevent water seepage.
- Environmental Remediation: Used to contain contaminated soils or to create barriers that prevent the migration of contaminants.
- Infrastructure Support: Provides stabilization and support for large infrastructure projects, such as dams, levees, and embankments.
This technique is particularly advantageous because it can be applied in a wide range of soil types, from silts to clays and even some granular soils, and it can be used in congested areas due to its relatively small operational footprint. Moreover, jet grouting is effective in creating structural elements with diverse shapes and orientations, offering flexibility in complex ground conditions and spatial constraints.
