A Unique Combination of Services and Technology

Our large fleet of specialized equipment allows us to take on any challenges, whether they be related to flowrate, depth, sensitive environments or areas with difficult access. We specialize in multi-year dredging programs, mine site restoration, remediation of water bodies and preventive or emergency ice breaking. On mining sites, dredging is used to optimize water management in tailings storage facilities, and to treat accumulated suspended solids and sediments.

End-to-End Sludge Treatment Solutions with Utmost Cost Certainty

ASDR uses a variety of dredges and water and sludge treatment technologies in order to provide tailored solutions. Dredging large volumes of water can thus be achieved with a high level of accuracy, while also providing us with the flexibility to adapt to each project’s unique challenges. The whole achieved with utmost cost certainty.
