28 Dredging DREDG20 – Amphibious Undercarriage The DREDG20 by 28 Dredging is a robust amphibious undercarriage designed for 18–22 ton excavators. Equipped with side pontoons and spud poles, it transforms a standard excavator into a fully amphibious machine capable of floating and operating efficiently in wetlands, shallow waters, and soft terrain. With the side pontoons mounted, the unit achieves full buoyancy, allowing seamless transition between land and water. The spud poles ensure excellent stability during dredging or excavation in open or unstable environments. Ideal for dredging, shoreline maintenance, and environmental restoration projects, the DREDG20 combines durability, modular design, and versatility — making it a reliable solution for challenging amphibious operations.
