The underground is the most complex
construction environment imaginable.


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.

Up Against A Wall

Installation of rock anchors for a 50-foot high, exposed retaining wall constructed in steeply sloping terrain was the challenge facing Moretrench during reconstruction of a section of State Route 38 in northwestern Pennsylvania. A value-engineered design and anchor installation using Moretrench’s specially adapted severe-access drill rig were instrumental in the success of the project.

Deep Shafts in Karst

Drill and blast installation of the three deep shafts through highly variable karstic conditions was the challenge facing the design and construction teams for Phase 2 of a 23,000 foot-long sewer tunnel in Columbus, OH. A specially designed pre-grouting program developed by Moretrench was key to successful excavation in the dry.

Stabilizing the Bridge

When foundation installation for a new bridge across the Intracoastal Waterway in Palm Beach County, FL, caused the timber foundations of the aging bridge it would replace to settle, a stabilization program was urgently needed to avoid having to close the bridge entirely until the new structure was completed.
