The underwater portion of the Detroit River Car Tunnel was continually plagued by water infiltration problems, causing extensive damage and deterioration to the structure. The multi-year restoration program, resulted in the near elimination of the infiltration, entailing multiple injection phases.
Two 660 meter long concrete strip footings support three large gantry cranes at the CP Vaughn Intermodal Terminal. The existing steel bearing plates between the footings and crane rail created a point-loading situation leading to rapid extensive cracking, deterioration and settlement.
ECO designed and directed a multi-grout, multi-technique post/pre-excavation grouting program to facilitate two mine slopes through water bearing strata. The grouting operation was executed by ECO trained miners.
ECO designed and directed a pre-excavation soil grouting program to stabilize the soils below the US23 artery prior to tunnelling. The tunneling crew was trained by ECO and the grouting operation was monitored in real time via CAGES…
A multi-facetted grouting operation included curtain grouting below dams, rock anchors and tunnel grouting operations to facilitate the construction of a hydro project.
ECO directed and designed a pre-excavation grouting program, monitored in real time, to facilitate the construction of a 2m diameter tunnel. The tunneling contractors crews were trained by ECO personnel and grouted the loose shot rock below a major highway.
