The island’s most northerly breakwater is to undergo a health check, as engineers prepare to drill into its ageing structure to help guide future repairs.
Ports of Jersey has submitted a planning application to carry out structural investigation works at St Catherine’s Breakwater.
The proposed 14-day project involves drilling boreholes and digging trial pits along the slipway and northern buttress to assess the breakwater’s condition.
The Grade-1-listed structure, completed in the 1850s, has shown signs of settlement and undercutting in recent years – meaning some areas have begun to sink slightly, while others have had their base worn away by the sea.
According to a statement submitted as part of the planning application, the works will be undertaken in daylight hours and timed around the tides, with measures in place to protect marine habitats and the surrounding environment.
