Fraser River Deep Freeze

Mining of Metro Vancouver’s new Port Mann Water Main beneath the Fraser River was well underway and the TBM was approximately 650 ft from the north bank exit shaft when an unanticipated mechanical failure occurred in the cutter head, halting mining operations.  Fast-acting liquid nitrogen ground freezing  proved to be the best solution to allow safe access for inspection and repair.

 

Ash Dewatering at Work

At a power station in the mid-Atlantic region, fly ash, bottom ash and boiler slag from discontinued coal-fired operations is stored in five surface impoundments, some of which date back to the mid-1950s.  Acting in compliance with current environmental regulations, the owner is moving ahead with plans to consolidate the four smaller impoundments, which are unlined, into the fifth and largest of the ponds, which will ultimately be capped.  In the first phase of the consolidation work, Moretrench was contracted by the General Contractor to dewater a 37-acre pond.

Shoehorning Drilled Shafts

The Overland Bridge Project is the largest transportation design-build in the history of Jacksonville, FL. The project includes replacement of a series of existing overpasses, widening of both I-95 and the Fuller Warren Bridge over the St. John’s River,  and replacement of an existing bridge spanning Florida East Coast (FEC) railroad tracks.  Installing the drilled shaft bridge foundations required for the project in extremely tight conditions between existing piers and adjacent to the active traffic flow was an exercise in precision, ingenuity and high-level safety awareness for Moretrench’s Orlando office.

South American Deep Freeze

When all previous efforts failed to halt soil and water ingress into a deep shaft under construction in Buenos Aires Province, Argentina,  Moretrench was called in to provide a ground freezing solution that successfully resolved the issues, allowing excavation to continue to final depth in the dry.
