Extensive Experience in Dredging and Dredge Manufacture

Neumann Dredging have over 60 years’ experience in marine contract dredging and dredging in mining applications, with the first dredge being built in the late 1950's for mineral sand mining. Since then we have built several dredges for our contracting fleet.

These dredges are high technology cutting and recovery machines with a well-earned reputation for performance and reliability in capital works marine dredging and in mining and resource dredging.

The dredges are de-mountable and can be cost effectively transported to remote sites around Australia and overseas. Dredging has proven to be a safe and cost effective method for the relocation or reprocessing of tailings.

Operational expertise built on contract dredging experience enables us to constantly improve our equipment. This culture of innovation gives us the edge as dredging contractors of choice.
