Flexcrete were chosen for the concrete repairs and decorative protection for a total of 2,500m2 balcony soffits and supporting beams at Byker Wall.
Byker Wall is a long unbroken block of 620 maisonettes in the Byker district of Newcastle upon Tyne. The area underwent a major £26 million refurbishment programme to restore the residential properties to their original high quality. Improvements over two years included new roofing, windows and doors to 400 flats and maisonettes, work on communal areas and repainting in line with the original colour scheme. Flexcrete products were specified for the repair and reinstatement of the concrete to the balcony soffits and supporting beams.
Following thorough preparation, all exposed steel reinforcement was treated with Steel Reinforcement Protector 841. Areas of spalled and removed concrete on the balcony soffits, edges and supporting beams were built up with Monomix, a high performance, low sag, waterproof structural repair mortar which can be applied up to 80mm in a single application.
Pre-packaged only requiring the addition of clean water on-site, it offers low permeability to water, even at 10 bar pressure, and very high diffusion resistance to acid gases and chloride ions. A final, decorative anti-carbonation finish was achieved by applying Monodex Ultra, a cost-effective, minimal VOC, waterborne coating which offers high diffusion resistance to carbon dioxide. Monodex Ultra is available in a range of aesthetic colours and light grey was chosen for this project.
