Profile: W & S Dredge Manufacturers offer portable dredges to be used in excavation activity or any operations usually carried out in part underwater. We provide badger class dredge and wolverine dredge. The badger class dredge can dig up to 15 feet deep. This 64' long dredge is ideal for smaller dredging jobs where more compact equipment is required due to work area limitations. The Wolverine can dig up to 25 feet below the surface and allows for a maximum particle clearance of 6″. This tough yet portable design is perfect for the light contractor and is fully functional by one person.
