  • 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.

Waste Containment Services

 

RECON has constructed 15 landfill cells and installed over 220 acres of landfill caps. These structures have included compacted clay, HDPE liner, geotextiles, geocomposites, soil, and vegetative cover. Cell construction and final containment system covers are executed with off-road and on-road owned equipment.

Waste Containment

 

RECON constructed a Corrective Action Management Unit (CAMU) at an El Paso, Texas refinery. The 17-acre CAMU was designed to receive contaminated soils and waste from existing onsite Solid Waste Management Units (SWMUs).

Project Features

 

• Excavating and stockpiling soils from half of the CAMU and installing GCL and 60-mil HDPE liner

 

• Returning the material to the CAMU, followed by the remaining material from the CAMU

 

• Constructing the rest of the CAMU to accept over 400,000 cubic yards of material excavated from the SWMUs and an additional 108,200 cubic yards of material from the property

 

• Covering the CAMU with 545,000 square feet of GCL and 60-mil HDPE and a rock cover.
