Soil Mixing
Soil Mixing is a construction technique that uses the introduction of an engineered grout or reagent to modify the physical or chemical characteristics of soil without excavating. The intent is to modify the soil so that its properties become similar to that of a soft rock, such as clay, shale, or lightly cemented sandstone. Augers are used to mix cement with the existing soil to form a soilcrete mixture. The technique has numerous civil and environmental applications and can use a wide range of mixing equipment. Soil mixing is also commonly used as a stabilization or in-situ fixation method for building and bridge foundations, retaining structures, liquefaction mitigation, temporary support of excavation and water control. Other soil mixing applications include containing hazardous wastes and sludges.
Soil Mixing
RECON stabilized the underlying soils beneath an approach bridge/overpass on Interstate 30 to the new Dallas Cowboy Stadium. RECON used the Deep Soil Mixing technique, consisting of a cement grout and in-situ soils.
Project Features
- Stabilizing 140,000 cubic yards of low strength soil
- Installing over 1800 columns on the north side of the interchange and an additional 2,900 columns on the sout
- Columns were 4-feet in diameter and reached a total depth of 26 –feet
- RECON performed this project with two RECON-owned RH drilling rigs

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.
