Stonework restoration of Evesham Bell Tower

Stonework restoration of Evesham Bell Tower

Restorative Techniques were specified to address the deteriorating stonework of the Evesham Bell Tower, through the removal of sulphation crusts and deposits, stabilising the decaying stonework and mortars, and re-establishing weathering’s in order to slow future decay.

The biggest challenge for this project was the sulphate skins (or carbonation crusts) which commonly occur in sheltered positions where the building design prevents natural wash-down by rainfall.

ThermaTech was used initially, but due to the high levels of crustation and the soft nature of the stone a nebular spray system was then used. This achieved better results in this case; lifting crustation and offering a very controllable cleaning solution, the nebular spray also reduced the amount of poulticing required.

By adapting the processes, the sulphation was efficiently removed whilst preventing over-saturation of the stone work. As a result the original surface of the stone was revealed without damage to the building.

Evesham’s Bell Tower is the most iconic building of the town, not only is this a beautiful building but it holds one of the best English-hung ring of bells in the world. The Bell Tower is also one of the last links to the great Abbey, a hugely important part of the town’s heritage.
