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

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.

Up creek with a paddle! Dealing with dense vegetation and invasive species from water requires specialist kit & teams. These works will enable Paddle UK to keep on top of the invasive species, floating pennywort going forward.

(3/3) Full credit to the team for an excellent job in challenging circumstances! Check out the before & after photos.

(2/3) Over 5000 bricks were laid with heritage lime mortar and finished with a cast in situ concrete coper. Managing a busy towpath and moorings with significant access constraints meant floating plant was essential to help lift & store materials and plant during the works.

(1/3) Tight spot and 5000 bricks to move & lay by hand! A full canal wall rebuild was needed along a busy moorings. After dewatering with a horseshoe dam the collapsed masonry wall had to be broken out by hand before a new concrete footing installed.

(2/2) The green oak wood is full of character and can also provide a sustainable material for building projects. #GRD

(1/2) What happens to old lock gates? After working with CRT to lift and change the old lock gates for new, the old gates are taken for recycling and upcycling. The gates are stripped down and turned into furniture, mantel pieces or planks for flooring.

(2/2) The boat has purpose built gate frames in the hold to carry the gates safely to meet stability calculations.

(1/2) Changing the Gate! Our 55ft hi-capacity crane boat with welfare was deployed to the Birmingham & Fazeley canal to change lock gates with CRT. The gates were loaded from Mancetter Wharf before being floated to site, with the old gates then collected for recycling.

(2/2) This involves using stop planks to drain down the lock & all associated temporary works including access, fencing, lifting etc. Our range of craft also helps provide stable working platforms, lifting assistance, welfare & material storage for works to be carried out safely.

(1/2) Our specialist lock teams have been supporting CRT with lock repairs during the busy stoppage season. From replacing collars, to repairing cills and strengthening existing lock gates we have the expertise to survey, source and then fit all parts of the locks.

Piling with a soft edge! The bank was collapsing, taking the towpath with it, so L8 sheet piles were installed. This created a stable edge to rebuild the towpath. But, the ‘hard bank protection’ had a soft twist with the addition of steel brackets to hold pre planted coir rolls

Our NATO pontoons with 8t digger and specialist grab were deployed to remove a sunken boat from the Fossdyke canal. The NATO pontoon provided the perfect stable working platform with its hydraulic jack legs, for the team to break up and remove the boat from the canal.

Our contracting teams have recently completed works to repair a concrete culvert & ditch along a busy footpath. The emergency works involved installing a temporary coffer dam ahead of casting new concrete aprons to several sections that had become undermined.

Our versatile 55ft powered crane boat has been assisting CRT with lock gates. The 11tm crane has a max radius of 7.5m lifting 1.3t. It can carry & lift lock gates into position with the operator having excellent visibility with the remote control. The boat also has welfare

Our experienced grouting team were deployed to Shropshire Union to seal a box culvert that was leaking. The old stone culvert was leaking into neighbouring fields and this could easily be sealed by injecting PU grout from the towpath & bank into the leak paths.

Our historic carrying boat Archimedes, was carrying school children this week. We used the boat to bring their ‘transport’ topic alive, showing them how the boating families lived, what the canals were used to transport – with milk for Cadburys chocolate the favourite cargo!

Latest crane NATO pontoon launched! The crane folds away for ease of moving around the waterways & can be bolted in different positions. Hydraulic stability legs give stable working platform. The crane has full 360degree rotation with remote control for ease of operation

Do you know what's needed for a safe lift? We have completed over 50 lifts of boats in past 2 weeks! Through auditing & meeting with our 'lifting legends' we reflect on what went well & what could be improved. All the lifts were undertaken safely thanks to our dedicated lift team
