In the first of several contracts for New York’s City Water Tunnel #3, ground freezing facilitates the sinking of three deep shafts.

1995

In an unusual application, ground freezing is used to prevent further erosion at an abandoned salt mine in Louisiana that houses 2.1 million gallons of the nation’s Strategic Petroleum Reserve. The freeze is maintained for five years while the oil is pumped out.

1997

Installation of 450 wells through the half-mile long dividing wall of Hillview Reservoir in New York provides the pressure relief on the wall that allows the twin basins to be safely drained and cleaned in turn.

1997

The Lenox Avenue subway reconstruction project in New York City involves dewatering of a 2,500-foot long subway tunnel section to allow concrete invert replacement. Well installation and dewatering is accomplished within the active tunnel.

1997

As an integral part of the design-build team, Moretrench provides the dewatering system for construction of the underground section of the Tren Urbano metro in San Juan, PR.
