Jet Grouting
Jet grouting is a general term describing various construction techniques used for ground modification or ground improvement. Grouting contractors use ultra high-pressure fluids or binders that are injected into the soil at controlled velocities. These binders break up the soil structure completely and mix the soil particles in-situ to create a homogeneous mass that solidifies. This ground modification/ground improvement plays an important role in the files of foundation stability, particularly in the treatment of load bearing soils under new and existing buildings; in the in-depth impermeabilization of water bearing soils; in tunnel construction; and to mitigate the movement of impacted soils and groundwater.
In order to bridge a gap between installed sheet pile sections of a bulkhead, underneath an operational access way pipe rack, RECON used jet grouting to support the wharf during dredging operations.
Project Features
- Installing the 53-foot long cutoff wall to a depth of 45 feet
- Interconnecting jet grout columns were installed at angles from vertical to 15 degrees under the access way
- Installing forty-eight, 36-inch diameter columns to complete the cutoff wall
- Installing a total fluids hydrocarbon groundwater recovery system in order to extract diesel from the groundwater.

Project Highlight
GT Omniport, a multimodal facility located in Port Arthur, Texas, is an industrial park and liquids terminal offering rail, truck, barge, pipeline and deepwater ship transloading services. The environmental remediation and civil service construction project included soil preparation, demolishing the concrete and steel structures, clearing, grubbing, crushing concrete, beneficial reuse of of crushed concrete, and soil stabilization using RECON’s patented blend of reagents.
