Jet grouting is a grouting technique that uses the kinetic energy from a fluid to loosen ground. The jets erode and combine the soil as the drill stem are rotated and lifted.
The jet grouting procedure assembles soilcrete panels, full columns or anything in between (partial columns) with constructed durability and permeability. Jet grouting has been used to underpin existing bases, construct excavation support walls, and construct slabs to seal the bottom of planned excavations.
Jet grouting is effective across the widest variety of soil types of any grouting system, including silts and most clays. Because it really is an erosion-established system, soil erodibility plays an important part in forecasting production, quality and geometry. Cohesionless soils are usually erodible by jet.
Jet grouting’s ability to build soilcrete in enclosed spaces and around subsurface obstructions such as utilities, supplies an unique amount of design flexibility.
Normally, jet grouting can be achieved without disrupting normal facility operations. The recent development of small containerized, highly mobile support equipment has empowered beginning jet grouting work on the first day of set up, greatly reducing mobilization and demobilization costs. Jet grouting can often lead to construction program savings.
Jet-Grouting is successful across a wide range of soil types presenting extensive variations in permeability and grain size distribution. The technique can be used in almost any soft soils, from soft clay to gravel and sand. However, the technique is not suited to grounds or coarse gravel with subterranean water flow.
