Stone repair and repointing - Grade 2 listed walled garden - July 25, 2017
Architectural Stone are working with Laing O’Rourke construction to provide stone repair and repointing to the Grade 2 listed walled garden on the Llanfrechfa Grange alongside the new Specialist and Critical Care Centre in Gwent. The 470 bed, 55,000m2 new build hospital will provide complex specialist and critical care treatment for over 600,000 people in South-East Wales, and includes a 24 hour acute assessment unit and emergency department.
A visual inspection of both the internal and external wall faces was carried out in order to assess their condition and structural integrity. The existing walls were generally observed to be in good condition with the majority of maintenance works to include the removal of vegetation and re-pointing. In more severe cases, the vegetation has penetrated the masonry walls and caused extensive cracking undermining the structural integrity of the wall. In these cases, where the vegetation cannot be removed without extensive damage to the wall, the stone walls will need to be carefully removed and then rebuilt to suit the existing wall geometry and construction.
We are working closely with the conservation officer ensuring vegetation removal, lime mortar repointing and removal and replacement of broken copings is completed in line with heritage requirements. We will also be dismantling and rebuilding parts of the wall and forming new openings to match existing. This important historical project is scheduled to be complete within 12 weeks
