Jet Grouting and Jet Mixing Techniques
Jet Grout Drill with Jets Activated
 |
Jet grouting, also sometimes referred to as jet mixing, is a method of grouting that uses very high pressure streams (6,000 psi or 40 MPa) of grout to erode, replace, mix, and cement soils. Jet grout construction uses a rotating and rising drill rod with small nozzles that direct the grout horizontally to form columns of soilcrete or soil-cement. Typical column diameters are 2 to 6 ft. Jet grouting is the only type of grouting that is capable of treating all types of soils from clays to gravel. Jet grouting is also useful in grouting isolated zones of soil and for grouting around and below buried utilities.
Creating Soil-Concrete Columns Using Jet Grouting Technology
There are at least three of types of jet grouting, some of which use air and / or water with the high pressure grout stream to improve soil penetration and column diameters. The procedure that is common to all jet grouting types (including double fluid jet grouting and triple fluid jet grouting) involves first drilling to the plan depth using small diameter drill rods. Next, a large and powerful pump is connected to the drill rod, which pumps the high pressure jet grout through the drill rods and horizontally into the soil. The drill rods are slowly rotated and raised creating columns of soil-cement. The shape of the grouted zone can be changed by directing the grout in ways that create panels, floors, or other shapes.
How Geo-Solutions Uses Jet Grouting & Jet Mixing
Geo-Solutions has used jet grouting to stabilize contaminated soils, create groundwater barriers and to underpin distressed foundations. Probably our most frequent application is the use of a jet grout with another technique, e.g. slurry walls or soil mixing, to extend the work into areas with limited access or into areas with concentrated utilities. Jet grouting uses smaller equipment and a small drill hole so it is well suited for work in tight quarters.

Geo-Solution's staff has extensive experience in jet grouting, double fluid jet grouting, and triple fluid jet grouting. We can provide a range of services for jet grouting from design mix studies to design/construction. For some projects, our services will include only the supervision, grout plant, jet pump, and key elements of the specialized drilling equipment. On other projects we can provide all of the services that may be required.
Geo-Solutions' World Class Jet Mixing & Jet Grouting Equipment
Geo-Solutions recently upgraded its jet grouting equipment with the acquisition of a new, state of the art jet pump. This pump is powered by a 600 hp engine and has one of the largest fluid ends available. This jet grout pump provides our clients with the opportunity for increased column diameters, greater production, and reduced construction costs.
