• Developed a low permeability/ temporary shoring solution that proved equally or more effective, less expensive, and faster to install, than traditional sheet pile or continuous caisson methods.
• Developed a slot cut excavation technique that allowed for the safe full depth removal of soil adjacent to the barrier wall.

Project Scope

• Designed and installed a low permeability wall to allow for site remediation up to a vertical boundary adjacent to a privately owned railway right of way, which intersected the three target properties for remediation.
• Supply, notification, and monitoring requirements associated with multiple ECA’s.
• Installation of 355 m of a low permeability concrete barrier using a bentonite slurry excavation technique.
• Wall dimensions were approximately 0.6 m wide by 5.0 to 6.5 m deep.
