Jet grouting is a ground improvement method that can be used for underpinning, water control, earth retention, and other geotechnical challenges. Jet grouting is well-suited for cased complicated by water or requiring targeted treatment.  It is effective across a wide range of soil types, including silts and most clays, making it one of the most versatile techniques. Jet grouting is and erosion-based ground improvement technique that can be used to construct a variety of geometrics, from thin vertical panels, to sector (partial) columns, to full columns of varying diameters. Further, soil-cement properties (i.e. strength, hydraulic conductivity) can be modified by controlling various grouting parameters. Parameters that can be modified include drill rod extraction rate, rotation speed, grout pumping pressures, grout flow, and the specific gravity of the grout. Lastly, the equipment can be sized to accommodate project needs ranging from low-headroom applications to treatment depths over 100 feet deep. This flexibility enables the technique to be tailored to meet the specific project requirements.

Wet soil mixing is the controlled mechanical mixing of the in situ soil with grout slurry using a rotary mixing tool. The wet method relies on the introduction of an engineered grout slurry to create soil-cement (soilcrete) elements for soil stabilization, or to support earth or building loads. The intent of the soil mixing program is to achieve improved engineering properties of the in situ treated soil, generally a design compressive strength, shear strength and/or permeability. Soil mixing can also be used to immobilize and/or stabilize contaminants, or as a chemical treatment system.
