Mat Sinking Unit is Reaching the End of Its Effective Life
• Built in 1948
• Cost of mandatory repairs @ $5-6M annually
• Numerous safety issues
• Spending money yearly in attempt to improve safety
• No automation requires large amount of manual labor
• No warning sensors to indicate dangerous conditions nearby
• Webs of cabling required to operate

A New Revetment Machine Will…
• Be more efficient and cost effective than current process
• Reduce the size of required associated plant
• Add higher paying technical jobs
• Reduce fuel consumption (carbon footprint)
• Reduce annual repair costs
• Have more automations and safer working environment
• Be more compact and mobile offering less channel restriction
• Allow armoring of the channel for the next 50 years

Controlling the
Mighty Mississippi
RiverWithout armoring, the River is a constantly attacking force capable of:
Cutting a new channel
Breaching a levee system
Destroying property and threatening populations
Interrupting navigation and commerce
Disrupting agricultural production
Endangering natural habitats
