Portland, Oregon

We recently completed our first D-Wall project in Oregon. “D-Wall” is short for diaphragm wall, which is a reinforced concrete wall excavated under bentonite slurry. This wall was part of our Value Engineering proposal to substitute the original design which was based on two sunken caissons with 20-foot thick tremie plugs. The circular wall acts as a compression ring and serves the dual purpose of a temporary shoring wall as well as part of the permanent structure for the pump station. We were able to offer major cost and time savings with this innovative Design-Build proposal.
