RETTEW’s Geophysics team recently assisted a client with a tunneling project. The tunnel path was at a depth at which surface geophysics could not resolve potential small zones of concern, including low-stiffness weathered rock that might require special support, and water-bearing seams that could flood the opening.

A high-pressure natural gas pipeline located in a right-of-way between two existing pipelines required inspection to evaluate potential flaws and any need for repair.
