Trench sheets provide edge protection to canal

Leeds to Liverpool Canal, Ormskirk

The Ormskirk section of the Leeds to Liverpool Canal is known as an area of natural beauty, visited by many walkers each year. It is home to many boat users with permanent moorings and an established vole population.

The Canal & River Trust (CRT) identified an area of canal bank in Ormskirk that required remedial repairs to be carried out to prevent any loss of the adjacent towpath, and further loss of coping stones.

The challenge

This needed a team of specialists who could carry out the work with minimum disruption to the public and wildlife, whilst allowing restoration of the original local coping stonework.

After CRT had designed the scheme and produced the drawings, Kier Construction’s dedicated Waterways team approached us for materials on a supply only basis. The programme required rapid sourcing of brand new interlocking M7 trench sheets. These were provided complete with galvanising to Waterway’s specifications, which formed permanent edge protection to the canal bank and lay beneath the waterline. We also supplied all necessary walings and fixings to protect the works from boat strikes and tie the pile line.

Our solution

We manufactured the sheet piles to the specific requirements at our rolling mills in Dewsbury, West Yorkshire.

The hard ground conditions required a stronger section which assisted the piling rig to install the piles quicker and to follow the curvature of the towpath. The towpath remained open at all times throughout the project, canal traffic was able to continue passing uninterrupted by the works and there was little disruption to the vole population.

The piling contract was successfully completed to the satisfaction of the client and interested parties. By combining the provision of new steel sheet piles together with the technical expertise of the local groundworks team, we were able to respond to all the challenges set by the client.
