The project, shown below, involved investigations into possible structural movement that was causing cracking to the ashlar stone on the Grade I listed building. Preliminary investigations were carried out in order to understand the structure, identify defects, and develop a specification for necessary remedial works.
During investigations, specialist consultants were invited to advise where necessary. It was concluded that the fault comprised water entering behind the stone ashlar, and moving debris within the void, which was forcing the ashlar out of line.
The resultant work involved the redesign of the stone cornice to contain a lead flashing, and the installation of stainless steel cramps to hold the ashlar in place against the main structural fabric of the building. It was most important not to disturb the appearance of the building. This successful repair addressed the cause of the problem without resulting in any obvious visual remedial works.
This project demonstrates that correct diagnosis at the commencement of a project is essential in order to save unnecessary work, costs, and then recurrence of the problem.
