  • Soil remediation, one discipline within the broader scope of environmental remediation, is the process of decontaminating soil. RECON is an industry leader in soil and sludge stabilization and solidification.
  • A secant wall is used in deep foundations in situations where the surface soil layers are unstable.
  • Among the processes used in soil remediation, excavation and dredging are among the most common. The process involves extracting unrecoverable contaminated soil.
  • Secant pile walls are one of the most economical methods of creating effective water control barriers for building structural walls, top-down tunnels and dams.
  • Deep Soil Mixing is a in-situ soil improvement technology used to construct cutoff or retaining walls and to treat contaminated soils.
  • This sludge pond is a good candidate for bio remediation or stabilization.
  • RECON's excavator is capable of digging a slurry wall up to 100 ft deep. Slurry walls have been used for decades to provide cost-effective, long-term solutions for many groundwater control problems.
  • Soil remediation project using remote placement conveyor.
  • Driving concrete pile to strengthen and support structural foundations.
  • Slurry wall construction is used to create non-structural barriers (Cutoff Walls, Slurry Trenches), which are constructed underground to impede groundwater flow.

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.
