CPT feature in Concrete Magazine

3rd August 2022

Concrete Magazine publishes article by David Bewley – corrosion control at Grade II listed Levita House using PatchGuardTM Strip, a novel galvanic anode system.

CPT were approached to design an appropriate corrosion control solution for this architecturally significant London Borough of Camden housing block. The challenge was to protect concrete encased I beams from expansive corrosion due to elevated chloride levels and carbonation. An innovative galvanic strip solution was proposed which offered the following advantages:

  • A minimally invasive technology, considered critical when restoring a Grade II listed structure
  • Self-powered, maintenance free, galvanic anode system with a 20 year design life
  • Unique anode strip design located within saw cuts in the concrete cover zone
  • A robust testing procedure implemented prior to project completion
  • Large observable shifts in steel potential following anode connection which, in all cases, was far in excess of the 100mV acceptance criteria in BS EN 12696 2016
