Innovative Dredging Equipment for Efficient Operations!

Custom Designed Dredges and Equipment

Neumann Contractors’  developed their first dredge in the late 1950s for mineral sand recovery, and since then, the company has designed and manufactured dredges for various inshore dredging projects.  As a result of the successful operation of our own modern and well-maintained dredging fleet, we have developed significant dredge operation skills as a dredging contractor.

Today the company has manufactured a fleet of cutter suction dredges with varying capacities.  Neumann dredges are high technology cutting and recovery machines and have a reputation for performance in specific contracts for infrastructure, mining and reclamation works.

Demountable and Cost Effective

The new generation of Neumann dredges is de-mountable and can be cost-effectively transported to remote sites worldwide.  Neumann Dredging has designed & manufactured many dredges for overseas countries, e.g. Russia, Canada, Saudi Arabia, China, Pakistan, India and Jordan.

These dredges can remove sand, gravels, clays, coral, slimes, weathered rock, and mine tailings.  In harbour and river works, where the cutter suction dredge might encounter a variety of natural and dumped materials, Neumann dredges have proven their versatility.  Neumann’s extensive dredging experience makes our dredges highly suited for various material types often encountered in flood prevention and environmental rehabilitation works.
