  • 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 Modification and Soil Stabilization

 

In-situ soil modification and soil stabilization techniques improve the bearing capacity of the soil to allow foundation construction at locations previously thought unusable. These stabilization activities are completed using RECON's patented low soils and sludge stabilization technology, which is a combination of fly ash, cement/cement kiln dust (CKD), lime/CKD, and other blends. Stabilization and modification technologies include using excavator with rakes or augers, jet grouting and soil mixing.

Soil Modification

 

RECON contracted to stabilize over 2,000,000 cubic yards of zero strength soils along the Gulf Coast for the construction of a new petroleum tank farm. RECON needed to stabilize 500,000 cubic yards within the first 6 months of the project.

Project Features

 

• Using a high calcium oxide ash to achieve the required 25 ps

 

• Stabilizing 3,500 cubic yards per day to meet the project schedule

 

• Using the top 8 feet of stabilized soils to construct secondary containment dikes, ranging 15 feet above existing grade.
