Ground Improvement for Tunneling (Live Seminar)

Paul Schmall, PE and John Grillo, PE, BC.GE

During this session, we'll explore the design and construction of specialty ground improvement work related to tunneling, including water control, soil mixing, and freezing, along with examples of where we've installed these techniques. We'll also discuss the selection process based on geotechnical conditions and design considerations.

Keller North America provides a wide range of geotechnical engineering and construction services to improve soils in place and to both construct new and rehabilitate foundations. The techniques that will be discussed include Compaction & Jet Grouting, Earth Retention and Shoring, Vibro Compaction & Replacement, Micropiles, Soil Mixing for Deep Basement Excavations, and Pile Driving. Within our range of services, a Ground Modification solution is generally available for the toughest subsurface conditions.
