Balcony mortar repairs

Technical mortars from by Saint-Gobain Weber have been specified for the repair of concrete balconies with metal railings to apartment buildings in Northwood in the London borough of Hillingdon. Metal railings around attractive balconies on the first and second storeys had rusted at the base over time, and this in turn led to spalling of the surrounding concrete. With technical advice from Weber’s specialist Barry Ephgrave, the team from Alfred Bagnall cut away the spalled concrete and repaired the metal barrier before reinstating the concrete. Saint-Gobain Weber’s Webercem concrete repair system was specified, a multi-component system compliant with BS EN 1504 for concrete patch repairs.
