  • 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.

Site Preparation

 

The term site preparation covers a wide range of activities that are defined by the project's design. However, regardless of the scope of work, it is the key to a successful project. Site preparation is the infrastructure upon which the project is constructed. These activities typically include site clearing and grubbing; rough grading of drainage swells; installation of construction roadways and laydown areas; construction of parking lots and pads for temporary facilities; and development of erosion control measures.

Site Preparation

 

To create space for an expansion project at a Gulf Coast refinery, two obsolete units – a sulfur dioxide gas unit and a sulfur conversion unit – were demolished. RECON cleared the site of all above and below ground structures and utilities. The underground portion required excavations to 8 feet below grade.
