Introducing the Geo-Trencher
Ideally suited for deep and narrow cutoff walls, in lieu of more conventional construction methods like slurry trenching, the Geo-Trencher is essentially a large mixing chain mounted on a tracked chassis. As a result, it can be used to mix soils in place with wet or dry reagents for creating an in-situ mixed-low-permeability cutoff wall or it can be used...Geo-Solutions gets SMART
Evading Canadian winter field work, Canada Geo-Solutions' Regional Manager Pete Craig snuck into the Smart Methods in Advanced Remediation Technologies (SMART) seminar series in Toronto (January 26) and Ottawa (February 16) to present on cutting-edge Permeable/Passive Reactive Barrier (PRB) technologies and related installation methods, including biopolymer slurry trenching, soil mixing and the Geo-Trencher™ single pass continuous trenching machine. Pete's presentation,...Geo-Solutions: Technical Training for Professional Development

Dan would like to thank the 70+ engineers, geologists, and contractors...Piano Key Excavation in Calgary, Alberta
Geo-Solutions recently completed a mass excavation and replacement using the cement-bentonite slurry supported excavation technique. This technique, sometimes referred to as a piano key excavation, can be used to excavate impacted or undesirable soils without the need for expensive dewatering or conventional excavation support systems. The cement-bentonite (CB) slurry serves as a liquid shoring and hardens in place to serve...
