Cintec Technology Aids in Restoration of Award-Winning 12th-Century Castle

Cintec Technology Aids in Restoration of Award-Winning 12th-Century Castle CINTEC International, a leader in the field of structural masonry retrofit strengthening, repair and preservation, announced that its patented anchors were used in the restoration of Astley Castle in Nuneaton, North Warwickshire, U.K. Following its renovations, Astley Castle was awarded the prestigious Riba Stirling Prize for Architecture. Cintec teamed up with architects and engineers from Mann Williams and Newport-based Protectahome to restore the castle. Cintec assisted Protectahome with the first phase of restoration, which included structural repairs and stabilizing the remaining walls of the building prior to rebuilding. Cintec’s patented anchors were used to stitch together and strengthen the walls.

The process of restoring Astley Castle involved using a diamond drill to insert steel anchors into the building. Once in place, grout was pumped into a special sleeve surrounding the anchor, and air was pumped out. Cores removed during this process were retained and reused where the anchors were installed, leaving an almost invisible repair. The work has ensured the survival of the original walls, allowing the award-winning holiday home to be built within the shell of the ancient castle. The Riba Stirling Prize is the U.K.’s most prestigious architectural award. Judging is based on original, imaginative and well-executed designs that excellently meet the needs of their users and inspire those who use and visit them. Cintec Technology Aids in Restoration of Award-Winning 12th-Century Castle “The restoration work on Astley Castle was an impressive enterprise, as anyone who saw the castle prior to its transformation could have been forgiven for thinking it a hopeless ruin,” said Peter James, managing director of Cintec International. “To be awarded the Riba Stirling Prize demonstrates the true extent of its transformation. It has now been turned into a structurally stable building that will stand the test of time and can be enjoyed by many people in its reincarnation as a holiday home.” Cintec anchors have been used to restore historically significant buildings across the globe, including Windsor Castle, the White House and extensive work on Egypt’s pyramids. A video tour of the house is available on the “ribaarchitecture” YouTube channel. The final project worked to a 60:40 ratio of old to new masonry construction.
