PROFESSIONAL
We have completed contracts for government agencies and large industrial clients to remove and dispose of contaminated sediments from the St. Clair River, the Livingstone Channel and industrial harbours elsewhere in the Great Lakes.
RESEARCH
We have developed systems and equipment which have been tested, proven and documented to protect the environment, even during large-scale marine drilling and blasting applications. Heightened international concern over the poor quality of the Great Lakes has focused attention on the need to reduce pollution, contain or remove contaminated sediment and remediate our environment.
