Liverpool’s historic Albert Dock and Dukes Dock could be set for underwater repair work under new plans submitted to the council.
Infrastructure company Mouchel has compiled a report outlining the need for structural repairs to walls at both docks, expressing concerns that failure to carry out the maintenance could eventually result in the collapse of quayside areas.
As much of the defects are beneath the water, the proposed repair work will require divers to enter the docks to reinforce the walls using underwater concreting techniques.
A report submitted to the council’s planning department reads: “Underwater defects present their own unique challenges when it comes to ensuring that a repair is both robust and durable.
“To this end, underwater concreting is a very common method of repairing such defects, due to its durability and the ability to ensure good quality control in a difficult underwater working environment.”
The report was prepared for Albert Dock custodians Gower Street Estates.
Sue Grindrod, chief executive, Albert Dock Liverpool, says: “Gower Street Estates take its role as custodians very seriously to preserve and protect the Grade I-listed heritage of the Albert Dock estate, which is located within a UNESCO World Heritage site. We have a continued commitment to maintaining the integrity of the built environment, which includes the dock walls.”
Some of the defects at Dukes Dock lie partially above the water level and the plans state that they will be repaired with masonry which will match the existing wall.
The repairs earmarked for Albert Dock lie at least 1.5m below the waterline and will have no visible impact on the heritage site.
