Soil Stabilization

Odin offers both in-situ and ex-situ solidification/stabilization technologies for soil and sediments. In-situ solidification/stabilization (ISS) can be achieved using a variety of methods including single vertical auger mixing, multi-auger vertical mixing, mixing with specialty tools such as the Lang Dual Axis Remediation Blender, jet grouting and excavator table mixing for shallower soil sections. Vertical auger mixing (VAM) consists of a crane mounted turntable with mixing heads between 4 and 12 feet in diameter.

VAM can be used to inject and mix a variety of additives including, but not limited to, pozzolanic materials, chemical treatment reagents, steam, and hot air to strip volatiles. In-situ treatment inherently reduces the potential for fugitive dust and vapor emissions, however when needed, a shroud and vapor collection system can be added to further control and scrub emissions.

Ex-situ solidification/stabilization (ESS) can also be performed using a variety of methods including backhoe mixing in place, in tanks, or containers; pugmill mixing; or treatment in lay down areas using discs or soil stabilizers. Backhoe mixing is the simplest method and most commonly used when physical and chemical treatment objectives are relatively simple and readily achieved. When soil or waste characteristics are more complex and when a higher degree of performance certainty and process control are required, pugmill or treatment pad mixing are more commonly utilized. Odin has the experience to help clients evaluate the technology that will best meet their project objectives.
