ASDR has over 20 years of dredging experience in mining, industrial, marine and municipal environments. We have a large fleet of specialized equipment, allowing us to meet any challenge, whether it is a question of flow, depth, precision, sensitive environments and restricted access locations. We are mainly specialized in multi-year dredging campaigns, the restoration of mining sites, the remediation of bodies of water and even spring ice breakage. The acquisition of Eco Technologies in 2022 allowed us to double our workforce while increasing our geographic presence across Canada and gaining access to highly specialized dredging equipment. When combined with our sludge conditioning units and our dehydration systems such as the GeoTube, this allows us to offer a complete solution to our customers. Discover the ASDR expertise.

ASDR provides a series of technical services to support the development and implementation of water treatment projects:

• Laboratory and pilot tests 
• Water balance
• Development of process flowsheets
• Selection of treatment processes and technologies
• Front-end studies (conceptual and feasibility studies)
• Assistance with permitting applications
• Detailed engineering

ASDR teams up with industry leaders to develop innovative technologies and tackle the most critical challenges. Our achievements include the ECOMUD system, a sustainable solution for mining drilling campaigns, and a new technology for ammoniacal nitrogen treatment.

In recent years, ASDR has been involved in a large number of dewatering and water management mandates for mining projects at the development stage. We have dewatered and treated water / sludge for facilities with capacities exceeding
30 million cubic meters. Our experience also covers various bodies of water, streams, and managing and treating surface water on site. 

ASDR uses both its ECOMUD technology and geosynthetic bags as key components of our dewatering and sludge management solutions. We also integrate market-leading technologies, such as centrifuges or filter presses to suit any project’s particular needs. ASDR’s expertise covers sludge generated by treatment processes, dredging of tailings ponds, the remediation of bodies of water and drilling cuttings.

Our experienced team of engineers, chemists, technicians and operators is available to operate ASDR’s water treatment units as well as those of our customers. Our expertise covers staff training, start-up, operations and maintenance, as well as audits for plant optimization, irrespective of the processes and technologies in place.
