2017

Around-the-clock installation of micropile foundation systems is required to support the eight temporary steel jacking towers needed to stabilize the Delaware River Bridge during emergency repairs to a cracked truss.

2016

Low headroom and tight access is the challenge during micropile installation of replacement water-based piers supporting a parkway roadbed running beneath historic stone arch bridges crossing the Sawmill River in New York.

2016

Horizontal ground freezing aids hand-mining of five cross passages for the Northgate Link of Seattle’s Light Rail transit system. For the first time, the entire system, including the freeze plants, are housed within the extension’s tunnels.

2015

Moretrench installs and operates a ground freezing system deep beneath the Frazer River in Vancouver, B.C. to provide the water tight cut-off needed to allow cutter head access to repair a stalled TBM midway into mining the new Port Mann Water Supply Tunnel.

2014

With a proven history of dewatering fly ash ponds, Moretrench is poised to respond proactively to the new 2014 Federal Regulations mandating a closure deadline, rapidly becoming intensely involved with working with the power manufacturing industry to develop and implement the optimal site-specific pre-drainage plans.

2014

In Buenos Aries, Argentina, every attempt had been made over time to halt persistent soil and groundwater ingress into a deep shaft under construction.  Ground freezing proved to be the only solution to providing the earth support and groundwater control needed to allow shaft completion.

2013

In a first-of-a-kind application in North America,  Moretrench successfully uses  ground freezing  to stabilize a highly pervious coralline formation to facilitate the mining of the Port of Miami  twin-tunnel cross passages deep below the groundwater table.

2012

Moretrench’s rock grouting techniques successfully seal very permeable karstic rock to facilitate mining of three deep shafts for the OARS relief sewer project in Columbus, OH.

2011

At Rukert Marine Terminal in Baltimore, MD, installation of a new 1,575-foot long underground storm water drainage system through gasoline-contaminated soils involved drawing on diverse expertise throughout the company to accomplish the extensive pipework, concrete work, dewatering and groundwater treatment.

2010

At the Northern Boulevard Crossing in Queens, NY, acknowledged as the most challenging aspect of the entire East Side Access Project, ground freezing provides a protective arch during SEM mining of a tunnel deep below the water table. Compensation grouting for heave/settlement control is a critical part of the overall program.
