Check out the weed at speed!!😎🌿 One of our weed harvesters in London @canalrivertrust @CRTSouthEast recording their route along the canal. #reedandweed #london #timelapse #timelapsetuesday #tugboattuesday #workingboat #canal #canalboat #canalandrivertrust #cleanercanals

Do you know your roles and responsibilities when lifting? How about when lifting from crane boats? The Rothen Group and @CanalRiverTrust hosted a joint lifting operations workshop day at Mancetter Wharf with @CRTSoutheast team lead by Ian Grice #LOLER #lifting operations #lift

Our team installed over 1,300m of pre-planted coir rolls & brushwood along the Cambridge Arm of the Gloucester and Sheerness Canal to support water vole mitigation & future habitat creation, overcoming restricted access with carefully coordinated plant & material deliveries.

This one off build gave us the chance to do things differently, returning to a traditional boatbuilding technique & bringing the cabin together one rivet at a time. A rare glimpse of generations-old craftsmanship, combined with the design & engineering behind every TRG boat.

Featuring our fleet: The new conver boats are now out and working! Check out the floating pennywort being cleared here with the conver boat into a hopper #mastenbroek #conver #pearsonhydraulics #INNS #canalweed #lakeclearance

Featuring Our Fleet! We’re excited to welcome 4 new Conver Weed Boats to our fleet! Our team recently took part in a dedicated training day, getting hands-on with the new boats to ensure they’re ready to deliver efficient, professional conservation services across our waterways.

Featuring our Fleet: We’re continuing to invest in our fleet, with FOUR new boats joining The Rothen Group to enhance our capabilities and support our work across the UK waterways. Built on tradition. Better by design.

We’re incredibly proud of what’s going into our latest boats. Our new-generation engines deliver the performance, reliability and responsiveness you want on the water. Check out a new river class, wide beam tug. Built on tradition. Better by design.

(2/2) we managed to install piles backfilled with concrete to stabilize the wall. The original sandstone copers were saved and re-laid along with reinstating the towpath behind. All works were undertaken from our floating wide beam digger pontoon, pusher tugs and hopper.

(1/2) Our team has successfully repaired a failed section of rotating wash wall along the Rochdale Canal. Working closely to @CanalRiverTrust & @CadentGasLtd to get an appropriate long term design across the line despite presence of high voltage gas cables…

Our HQ is an RYA accredited training centre.Some new team members have just had the first stage of their helmsman training, starting with the RYA helmsman course. The team boated down the Atherstone lock flight and carefully negotiated turning round in a winding hole!

Check out our digger pontoons loading materials into hoppers at remote locations!

(2/2) With a warm and sunny spell forecast over the coming weeks, we’re fully prepared for the increase in aquatic weed growth and bloom activity that comes with it. Looking forward to another busy season helping keep London’s waterways clear, safe, and navigable.

(1/2) Let the clearing commence! We have officially started the 2026 weed season across the London waterways network. Our boats are now positioned around the network & the team has already cleared the first patches of floating pennywort, floating weed & rubbish from key areas.

(3/3) We then had the delicate operation of breaking through into the round brick culvert without causing significant collapse or damage. Works were completed successfully - see the photos below.

(2/3) Due to the remote location all materials and plant (including an 8t digger) had to be floated to site to lift the trench shoring and manhole rings into position.

(1/3) Need a tricky manhole installing? We are your team! An old brick culvert which is still integral to water management along the Shropshire Union canal needed a new manhole constructing to facilitate safe inspection.

After installing stop planks and dewatering we could undertake all timber and steel repairs to achieve tight seals and fully functioning gates.

The never ending project! Works to Kegworth deep lock seemed never ending after freezing temperatures & then flooding disrupted the works programme by 2 months. Repairs were needed to repair the lock gates where significant leakages were noted from missing or rotten lock timbers.
