Ideal Deep Foundation in Marine Environments
A drilled shaft (caisson) is often installed in the construction of foundation piers for bridge, tower and harbor applications in marine pile environments. This permanent deep foundation is ideal for use in various soil conditions and offers high load bearing capacity.
Cased Ahead Shafts
Morris-Shea pioneered the use of double-wall sectional casing using the high torque available with our rigs to install “cased ahead” shafts. The cased ahead construction method removes the need for slurries in many cases and results in less soil disturbance, giving higher unit shaft friction values. Our comprehensive range of equipment, experience and in-house design capabilities offer unique and innovative solutions to drilled shaft projects
