We were contacted by Liverpool Council / Kier to ask to tender for the Arnot St. Mary School Project, a listed building. Liverpool Council, are being advised by Kier throughout the project’s duration.
For over three years, the classrooms at Arnot St. Mary School have suffered from leaks and internal plaster damage at the base of each apex. This initiative aims to prevent any further water intrusion and to repair all internal damage.
The project involves replacing the existing terracotta coping stones with Leca® Uno. A material known for being easier to move into position and fit compared to a heavier filling material
The project will be executed by a skilled team from Quadriga Ltd, in collaboration with Kirk Scaffold and Darwen Terracotta. This collaboration is crucial for ensuring that the work meets the high standards expected by the council while ensuring minimal disruption to the school’s activities. By taking these measures, the project promises to enhance the structural integrity of the school buildings.
The Solution
All the terracotta coping stones will be replaced, except for the top decorative fleur-de-lis, and a damp proof course (DPC) installed underneath to prevent future water ingress. Leca® Uno is being utilized to fill the sections where terracotta was replaced, as it is a lightweight filler. This makes it much easier to manoeuvre and fit the terracotta compared to using a heavier filling material.
The use of advanced materials like Leca® Uno not only facilitates easier handling during the restoration process but also underscores a commitment to sustainability. This is the result of reducing the carbon footprint associated with transportation and installation. By selecting materials and methods that prioritise both functionality and environmental responsibility, the team is setting a benchmark for future projects.
Additionally, this approach reduces the overall weight on the structure, minimizing the risk of further damage over time. The team has also ensured that all replacement sections match the original design in both color and texture, maintaining the aesthetic integrity of the building.
This meticulous attention to detail and commitment enhances the building’s resilience against the elements. The project exemplifies a harmonious blend of traditional craftsmanship and modern engineering solutions. It also showcases how listed buildings can be repaired to withstand the test of time.
