Stable. Modular. Built for Waterway Excavation.
When land access isn’t an option, our digger pontoons deliver. Designed specifically for canals, rivers, and restricted inland waterways, these modular pontoons serve as a stable platform for excavators up to 8 tonnes – even in shallow water or narrow locks.
Riparian and marine sites offer a challenge. Our machines feature hydraulic stabiliser legs, shallow draughts, and swing-away sponsons for tight bridge clearance. Whether you’re operating directly from the deck or tracking from the bank, there’s no danger of the boat capsizing.
Work confidently, no matter the location – with or without an operator.

“The Rothen Group’s knowledge has ensured that potential issues were highlighted early, meaning projects run smoothly and on programme. They have a large fleet of plant and operators too, which reassures that the work will be completed safely and with due care.”
