Horizontal Auger Dredges

Used mostly in sand maintenance and coastal marine applications, horizontal auger dredges are a great option for applications that require less turbidity. As they usually are less disruptive of marine life, these dredges with a wide coverage area provide a wide berth of dredging ability and typically complete a large area in a less amount of time. They’re used mostly for soft soil and sludge applications that are up to 20 feet under the surface.

Utilizing vertically placed cutting teeth on a rotating auger, horizontal auger dredges cut into the earth and loosen sediment which is fed manually to the intake of the pump. These dredges allow the operator to have a more controlled result with the depth of the cutting as well as the positioning of the auger. Auger dredges also allows for sediment to be removed while taking less water from the area, thus a less disturbing process. Many dredge owners choose a horizontal auger dredge for its fluidity of movement – they move across the water by a winch attached to an anchored taut cable and can cut while moving both forward and backward.

If you’re in the market for a dredge that has more rugged capabilities, our mechanical dredges will offer the freedom for long haul applications with hard packed sediment.
