Hadrian House

The roof, which is also a busy walkway between two areas of the city of Newcastle, has over 300 linear metres of movement joints and it was these that had failed. The specification called for the removal of the existing movement joint, then the application of a bespoke, project-specific, Xypex joint repair. Xypex Concentrate Dry-Pac and a Xypex Concentrate slurry coat were utilised before Xypex FCM was applied as a final coat to facilitate some movement at the joints without the risk of further water ingress.
