Excavations in an urban environment often encounter contaminated soil and/or groundwater. GeoPrac sponsor Moretrench is an expert in geotechnical construction methods for preventing the contamination from entering or leaving a site. In a recent blog post, Moretrench highlighted four construction techniques for meeting these objectives. They are: slurry trenches, jet grouting, permeation grouting, and ground freezing.
Moretrench’s environmental remediation options are as varied as the contaminants and project objectives they are designed to address. Groundwater and wastewater recovery and treatment options include customized treatment systems and hydrocarbon recovery and dual phase extraction. In situ treatment methods include air sparging/soil vapor extraction, permeable reactive walls or chemical oxidation. Geotechnical methods used by Moretrench to create subsurface barriers include slurry trenching techniques and grouting systems.
Much like Moretrench, On Track Drilling also offers a range of landfill-related design, installation and maintenance services for both passive and active gas collection and condensate and leachate collection.
