Barrier Techniques

By October 24, 2014 No Comments
Impermeable subsurface barriers contain or inhibit the flow of groundwater. They may be installed down gradient of a known contaminant source, such as a landfill, to prevent the migration of contaminated water off site, or up gradient of a contaminated zone to prevent the f low of clean groundwater down gradient. Methods used by Moretrench to create subsurface barriers include slurry trenching techniques, grouting systems, and ground freezing.
