John H. Edens & Paul Schmall, PhD, PE
Diaphragm walls are very rigid walls offering significant resistance to bending from lateral loads as well as being water resistant. They can be used for a number of applications, including slope stabilization and groundwater barrier, but are ideal for lateral earth support for deep excavations and are often incorporated as the permanent building basement walls.
Ground freezing is a technique that freezes the pore water in the ground to impart significant compressive strength to soil and make it impermeable. It is most commonly used with tunneling as a technique to provide complete groundwater cut-off and earth support.
This presentation will review the technique basics, general engineering principals and operational details of these techniques.
Keller North America provides a wide range of geotechnical engineering and construction services to improve soils in-place and to both construct new and to rehabilitate foundations. The techniques that will be discussed include Compaction & Jet Grouting, Embankment Stabilization & Excavation Support, Vibro Compaction & Replacement, Micropiles and Pile Driving. Within our range of services, a Ground Modification solution is generally available for the toughest subsurface conditions.
