Stanthorne Breach Repair Project

In March, 2018 a 70m section of the Shropshire Union Canal in Cheshire, collapsed causing the closure of the canal. Around 2,800 cubic metres of the Middlewich embankment had been washed away into the River Wheelock below.

Before the Stanthorne Breach Repair Project construction could begin, CPC Civils would need to create access into the canal. We would achieve this by installing an access ramp and a 100m long haul road through the canal bed. This would allow us to reach a stranded canal boat enabling its safe recovery.

Following the canal boat’s removal, the haul road would need to extend through the 60m of breached canal. This would require the removal of large sections of concrete and other debris. We would also need to and make the surrounding slopes safe.

We would extend the haul road a further 60m to allow the construction of a permanent dam and the removal of the temporary fabric dam.

A tracked dumper was required to reach the bottom of the breach where the repair works would begin.

Upon clearance of the river bank an excavation began at the toe of the embankment to find suitable ground to begin rebuilding.

The rebuild was completed by laying and compacting layers of stone 150mm at a time, for a total of 14 metres. This would match the intact embankment profile either side of the breach.

220 Metres of reinforced concrete wash-walls were built through the site. We would also fit a waterproof geotextile membrane throughout the confines of the wall. This would seal the canal bed. The membrane was lined with a 100mm thick fibre reinforced concrete layer. This would provide the necessary protection.

It’s also made my job very enjoyable”
