World-leading dredging technology designed for non-potable applications in the processing, wastewater, industrial, manufacturing and mining sectors.
Purpose-built to operate in lined and non-lined ponds, process tanks, cooling towers, covered anaerobic lagoons, chemical ponds, non-potable reservoirs and turkeys nests.
Our proprietary dredging robots allow assets to remain fully operational during dredging and is low risk as it completely removes the need for human entry.
Dredge Robotics diverse capabilities include:
• Liner-safe, trackless drive systems for lined assets
• Oil-less, fully electric systems
• Assets remain online during dredging
• Operates using environmentally friendly Panolin oil
• No confined space entry or barges
• State-of-the-art navigation and tracking systems for nil-visibility conditions
• The ability to operate in corrosive environments
• The capability to minimise turbidity
• Removal of 100% of sediment
• Lowest risk option
• World first technology
• Designed and built in Australia
