A concrete repair survey of concrete balcony's at the Byker Wall revealed a number of defects and instances of structural concrete failure.
Water had penetrated through the timber panels and the process of carbonation had occurred to some extent, resulting in the spalling of concrete. The reinforcement is clearly visible in this image.
Defective concrete was cut out. The steel reinforcement was then thoroughly cleaned and coated with an epoxy primer.
Carefully constructed shuttering was assembled to allow the reinstatement of concrete.
A fully restored balcony, complete with anti carbonation coating.
This support had failed to the point that it was in danger of falling on a passerby. All defective concrete was reomved before the steel reinforcement was cleaned and treated.
Fully repaired concrete support. Repair mortar was hand applied to achieve the finish.
Winner of a number of high profile awards including the Civic Trust Award and the Veronica Ridge Green Prize for Urban Design (awarded by the University of Harvard, U.S.A), The Byker Wall, was designed by Ralph Eskine and finished in around 1982.
Placed on UNESCO’s list of Outstanding 20th Century Buildings, the Byker Wall has around 9,500 residents and was also the home to ‘Rat Boy’, a juvenile delinquent who inhabited the structure’s heating shafts during the 1990’s.
We carried out extensive repairs to the concrete elements which form the balconies, and due to their nature such work often requires immediate attention. The correct diagnosis of the cause is as important as the concrete repair itself, otherwise fractures will continue to occur.
