Dredging Along the River Don
The Rothen Group recently did some works at the Tidal Doors along the River Don. The doors had become severely silted up resulting in localised flooding.
Our dredging team had a narrow window to clear the area due to being in a tidal zone and adhering to strict health & safety regulations.
Clearing Weeds at Titford Feeder
The Rothen Group cleared part of the Titford canal system of reeds and vegetation to enable boaters to reach the highest point on Birmingham’s canal network again. Using our long reach excavator, the bankside vegetation was cut and then the reeds removed through dredging.

Bank Protection along River Tern
A mix of soft and hard bank protection was needed to prevent a garden from disappearing into the River Tern. Nicospan and sheet piling was installed from the bank.
Piling Works for Anglo Welsh
The Rothen Group have installed a large amount of sheet piling at Tardebigge marina for Anglo Welsh. The piling was installed along a section of unstable bank to the front of properties and private moorings. The works will create a stable bank.
Leak repairs undertaken in Huddersfield
Three large voids had opened up behind the canal wall and within the towpath causing concern for boaters, the public and wildlife. The voids were over 1.2 m deep and filling with water at a rapid rate which was undermining the canal wall.
Piling works at Greensforge Sailing Club
The Rothen Group installed sheet piles along the waterfront of Greensforge Sailing Club. A marine ready, specialist mini digger and piling hammer was used to install the sheet piles from the bank reducing the cost for the client.
Dredging for Environment Agency
The Rothen Group finish dredging for the Environment Agency along the River Nene and River Great Ouse. Over 8 locations were identified as ‘critical’ during surveys carried out by the EA due to a build up of silt and deposits in the main river channels.
Bank Stabilisation works in Coventry - piling and towpath reinstatement
In Coventry urgent bank stabilisation works were needed to stabilise the canal wall and prevent the towpath from collapsing into the canal. The works had to be undertaken from floating plant. Our mini digger pontoon provided a stable platform to place a 2.5t marine ready mini digger on to both breakout the concrete wall and hang a piling hammer off to install the new piles.
Leak repair in Skipton
A very bad leak was present along a 30 m section of canal wall in Skipton. The water was flowing through the dry stone wash wall and down the embankment slope jeopardising a railway line adjacent to the canal and residential properties beyond that.
Nicospan Bank Protection at Barford
The Rothen Group have recently installed a section of nicospan bank protection along the River Avon in Barford. The works were desperately needed as the clients rear garden was collapsing into the river. Due to the ecological sensitivity of The River Avon a soft bank protection was best in this case, whilst still providing a high quality and economical form of erosion control. Pre planted coir rolls were used to and the benefit of its ‘open pocket’ structure enables vegetation to grow through the protection and therefore create excellent habitat. Soil was then used to back fill and the garden graded to create a stable edge to the garden.
Batchworth Moorings is located on the Grand Union canal near Rickmansworth. Over time the original concrete wall and coping had failed and collapsed and was in violation of the canal and River Trusts minimum safety standards. First we had to break up and remove the original wall.
2.4 metre trench sheets were then installed and back tied.
Marbury Embankment is Located on the Llangollen canal.
The 4 metre high embankment was in danger of breaching due to Badger excavations which were causing the embankment to collapse and leak. Once the badgers had been removed under a DEFRA licence, a 100 tonne clay
bund was installed at a 45 degree angle along the front of the pile line.
Sawbridgeworth is located on the River Stort. Due to the winters higher that average rainfall, the rivers levels had increased, leading to a 12m long breach.
2 metre Trench piles were driven and back tied along the front with a continuous 6 metre section of shorter 1 m trench pile along the rear of the towpath.
Gunpowder Wharf Piling
GunpowderWharf is located near Kidlington on the Oxford canal.
There were two sections of failed walling to the north and to the south of the Wharf. Firstly the original concrete coping had to be broken up and removed from the pile line. 2.4 metre trench sheets were then installed and back tied.
Lock 59 is Located on the Chesterfield canal at Retford.
The original stone wall had collapsed outside the lock cottage, making access along the towpath dangerous.
Hose Badger Exclusion
Hose embankment is located on the Grantham canal.
A scheme was required to exclude the badgers from the embankment and towpath and install a suitable long term barrier.
Coseley Tunnel Collapse
Coseley tunnel is located on the Birmingham main lane canal.
Due to high rainfall levels the embankment had slipped making access along the towpath impassable. Using our mini digger pontoon boat we were able to remove all the slipped material without placing a machine on the towpath.
Hurleston Wash Wall Repairs
Hurleston wash wall is located near Nantwich on the Shropshire union canal.
The works required a new coping to be cast in one pour on top of the original wall, this required 14 metres of ready mixed concrete to be transported approx 1 mile to site using one of our 70ft long powered carrying vessels and discharged directly into the shuttering.
Atherstone Side Pond Clearance
The side ponds at Atherstone had not been cleaned out in over 20 years. Although now disused, they still serve an important role as by-weirs diverting any extra water to the pound below.
However due to the large build up of silt and reed bed growth they were no longer working efficiently.
