Soil Mixing: 2,778 CY of soil up to 15 feet deep; 100% Self-Performed
Description of Work:
The purpose of this project was to use single auger soil mixing to treat pesticide / xylene contaminated soils with sodium persulfate and lime. Geo-Solutions was subcontracted to complete all of the soil mixing work. The soil mixing required the installation of ninety one 8 feet (2.44 m) diameter soil mixed columns to depths of 15 feet (4.6 m) below workpad elevation.
All of the soil mixing work was completed using Geo-Solutions’ Delmag RH-18 drill rig, batch plant, and silos. Prior to Geo-Solutions arrival, the surface soils were stripped away to expose the contaminated subsurface. The treatment took place within a mix “bowl” which helped to reduce external exposure to the soil mixing spoils.
