Open Tender Issued for Rocque Poisson Revetment Works

Friday 17 April 2026

An open tender has been issued for revetment works on the rocks along the beach at Rocque Poisson, as part of the Committee for the Environment & Infrastructure's ongoing coastal infrastructure maintenance programme. These works are due to begin in the summer.

This section of the sea wall has been closely monitored, with previous targeted repair and reinforcement works having taken place over the last few years.  This new programme of works will aim to:

• Further protect the sea wall and its foundations from wave impact.
• Reduce the washing-out of sand and soil from underneath the road surface.
• Reduce the amount of sea water 'overtopping' during storm events. This rock revetment will be a sloping bank of large rocks, each weighing approximately one to four tonnes. This absorbs the impact of sea waves and breaks them up as they reach the sea wall.

It will be built in phases, and the rocks will be locally quarried granite using stock from Les Vardes and newly extracted rock from Chouet. The revetment will not extend further than the end of the existing slipway and water outfall, so access to the beach will not be significantly impeded once the revetment is in place.

A small bank of rock armour was placed against part of this sea wall in 2022. The new revetment will be a significant expansion of this - built at a shallower slope, extending further from the sea wall, and using heavier stones to make it more durable.
