Esh Construction has been appointed to carry out essential repairs to Abbeydale Dam in Sheffield in a £1.3 million scheme, with works now under way. The 18th-century dam forms part of Abbeydale Industrial Hamlet, a Scheduled Monument and one of the city’s most valued heritage sites.
Serious leaks were identified two years ago in the dam’s north-east corner, allowing water to pass through the walls and creating dangerous pressure. Temporary emergency measures reduced water levels and stabilised the structure, but permanent repairs are needed to protect the site.
Michael Sherrard, Construction Manager at Esh Construction, said: “Abbeydale Industrial Hamlet is a unique and historically significant site. Esh is proud to bring its expertise in heritage restoration to ensure this landmark remains safe and operational for generations to come.”
Following the project’s award by Sheffield City Council, working in partnership with Sheffield Museums Trust, Esh has undertaken extensive site investigations over the past 12 months and developed restoration designs alongside JC Consulting. The repair programme includes rebuilding and repointing displaced stonework using traditional stonemasonry, installing clay linings and waterproof membranes to prevent future leaks, and grouting voids to strengthen weakened areas.
A working forge next to the spillway to the River Sheaf will also be underpinned as part of the contract. The technique involves placing concrete bags beneath the forge and grouting remaining voids.
Given the site’s Scheduled Monument status, all activities are proceeding under consents from Historic England and with permits from the Environment Agency. Access will be provided via a temporary causeway across the reservoir, enabling the team to work in a dry zone while maintaining water retention.
Works are progressing during Abbeydale Industrial Hamlet’s winter closure and are expected to complete by summer 2026. Alongside the dam repairs, Sheffield Museums will finish its Embrace Abbeydale programme, supported by The National Lottery Heritage Fund, adding a new welcome hub celebrating the site’s history and a timber-framed play area for families when the attraction reopens in spring.
Cllr Ben Miskell, Chair of the Transport, Regeneration and Climate Policy Committee at Sheffield City Council, said: “Safeguarding Abbeydale Dam is vital to preserving one of Sheffield’s most significant heritage assets. This repair programme tackles long-standing structural challenges and provides the stability needed for the future. We’re proud to be working with Esh Construction and Sheffield Museums Trust to deliver improvements that respect the dam’s historic character, enhance public safety, and ensure it remains a valued amenity for visitors for generations to come.”
