We specialise in advising and undertaking marine, civil and environmental engineering Nationwide. Our services include dredging, sheet piling and bank protection through to bridge inspections, reed clearance and general maintenance.

We have one of the largest fleet of specialist narrow & wide beam floating plant in the country. These work boats range in size and application and can be fitted with specialist equipment enabling them to be tailored for the client’s individual needs. We pride ourselves on being able to supply workboats to undertake works in difficult site conditions with restricted access. Our custom built pontoons can be; specialist machine transporters, operating platforms or fitted with a hiab crane. Being modular, these pontoons can easily be transported via a hiab lorry for quick, efficient delivery.

Our well trained professional staff deliver a high quality of work helping us achieve good term client relationships. Our extensive experience of inland waterways is readily available to clients and our proactive approach at the planning stage has helped our clients deliver more cost effective and time efficient projects.

The Rothen Group provide a high quality, work boat rental service supplying an array of large and small work boats for narrow beam & wide beam waterways.

Our range of boats include pontoons, pusher and powered tugs, hoppers, crane boats to commercial workboats and punts/flat boats that can be used in a variety of applications. If depth is a consideration, we have shallow draught work boats both powered and unpowered or if materials need to be transported we have both insulated and large materials hoppers. We also hire welfare and survey/inspection craft.

Our swiss army knife of commercial workboats - the pontoons are capable of transporting a 1.5 tonne to 8 tonne machine to awkward access sites, where the machine can either be tracked off the pontoon to work or it can operate from the pontoon itself, with the stability legs down. The machine can be tracked up and down the pontoon to work with no danger of the work boat capsizing. In addition, we have a variety of cranes for lock gate replacement works or piling operations. The pontoons are highly adaptable, with side stability tanks which swing round to enable them to fit through narrow bridges and locks.

The crane boats and grab barges available offer a bespoke option for your project. Whether you are replacing lock gates, piling, post driving or needing to lift materials we have a crane boat for you.


The Rothen Group has extensive experience in carrying out all types of contracting and civil engineering on inland waterways across the country. Our advice and approach will be pragmatic and result in the best solution for your specific project, whether it be bank protection, dredgingmarina works or waterway restoration on canals, rivers or lakes.

Our bank protection experience includes both hard and soft bank protection. We have undertaken a range of piling contracts (hard bank protection) where we consider both depth and marine conditions as well as usage and wear/damage.


This will ensure the sheet piling is suited to the site and your needs. Knowledge of which piles or bank stabilisation technique to use for each site can save you considerable sums and we are confident in assessing whether steel sheet piles, timber piles, plastic piles, nicospan (soft bank protection) or even gabion baskets are appropriate.



The Rothen Group have a range of machines and attachments to suit your requirements from piling hammers, post driver and mini diggers through to clam shell grabs and long reach arms.

Our range a machines can sit both on or off our floating craft. These include micro diggers, mini diggers and up to 8 tonne diggers with/without canopies for ease of moving under low bridges on the inland waterways. The lightweight machines are ideally suited for towpath works where low impact is integral to Canal and River Trusts weight restrictions. All of these machines are fitted with the latest LOLER technology including drop control valves, are marine approved and run on bio-oil.

Long reach arms have been built for all our machines to broaden their uses to long reach dredging etc.

The variety of attachments The Rothen Group can offer includes reed rakes, clam shell grabs, coping stone lifters through to specialist piling hammers, breakers and post drivers. These are all highly adaptable to suit your specific requirements.

Our bespoke range of piling hammers is available from our sister company RG Piling Hammers.
