Concrete Repairs to Five LPS Tower Blocks, Birmingham: 2016



  • Five thirteen storey tower blocks constructed in 1967 using the Large Panel System.
  • The inner faces of the parapet wall panels showed evidence of deterioration, with visibly spalling concrete and exposed corroding reinforcement. 
  • Site investigations concluded that the damage was caused by low cover to the reinforcement and excessive carbonation levels.


  • Repairs undertaken to damaged areas of concrete, along with replacement of reinforcement, the application of a migrating corrosion inhibitor and the renewal of deteriorated movement joints.
  • Exclusion zone set up around base of each tower block as a precaution against falling concrete with a ground based banksman maintaining two way radio contact with operatives working on the roof.
