Emergency repairs to historic Lyme Regis Cobb after storm damage leaves structure at ‘risk of collapse’
Urgent repairs could start next week on Lyme Regis’s historic Cobb after serious storm damage left large holes beneath the structure
Emergency repairs to one of Dorset’s most recognisable landmarks, the iconic Cobb at Lyme Regis, could begin as early as next week after severe storm damage left the centuries-old harbour wall at risk of collapse.
The structure, which is widely regarded as the earliest surviving example of its kind in the country, has developed a ‘large void’ beneath the waterline.
Experts warn that without urgent repairs, sections of the stonework above could give way.
An assessment commissioned by Dorset Council found that waves has created a hole up to two metres deep, seven metres wide and 30cm metres high, leaving “large blocks unsupported deep within the structure and at imminent risk of collapse”.
The report concluded that urgent works are required due to its vulnerable location and the possible impact winter storms could have.
The proposed £350,000 emergency works will involve pumping high-pressure concrete into the void to stabilise the wall.
A specialist archaeological report described the Cobb as “of very high importance”, citing its unique place in Britain’s maritime heritage.
Repairs will be timed to coincide with spring tide lows, giving engineers a window of just four days in early November to complete the work.
The special concrete being used sets within two hours, allowing limited working time between tides.
Fishing operations from the harbour are expected to continue, although the Cobb roadway will close to commercial traffic, restricted to vehicles delivering materials.
Once the void is filled, one-tonne concrete blocks will be placed by crane in front of the repairs to absorb waves and prevent further damage.
