Waterford
Walls Founded by the Vikings between 856 and 914 the city of Waterford is over 1000 years old. The city was fortified from an early date and the annals of Ireland mention the existence of a dun or fort at Waterford in 1088. By 1705 the wall running along the Quays was demolished. Fortunately six towers and large sections of city wall remain today. The remains of a stone built Viking Age gateway that once stood at the top of Peter Street was uncovered in 1989. Cornerstone carried out complete restorations to these historic medieval and Viking walls and towers surrounding Waterford city.Project Team: Conservation Architect: Christopher Southgate & Associates Structural Engineers: Horgan Lynch & Partners Quantity Surveyors: Bruce Shaw Partnership Main Contractor: Cornerstone Construction The scope of this project included the recording of all existing masonry with measurements and before/after photographs. Cornerstone has extensive knowledge of lime plaster techniques and structural repairs. The project began with removing vegetation and cleaning all the masonry, raking out the existing pointing and dismantling unstable masonry for reuse. This process was meticulously recorded with measurements and photographs. The next stage of the project was to rebuild areas to match previous face and joint lines, joint widths and bonding. Due to the nature and age of the structures, numerous structural repairs were necessary. These involved pressure grouting to weak areas of masonry. To reinforce the walls, tie rods were inserted into bearing rock and underpinning was carried out to masonry walls and towers. Finally, the walls were pointed in conservation lime plaster and masonry and lead capping to walls as necessary.
