Reinforced Concrete Restoration - Omni Centre Car Park, Scotland

Challenge: C-Probe's LoCem® +chase® anode mortar has been installed at the Omni Shopping Centre Car Park in Edinburgh, Scotland to 4 levels of underground car parking as part of a comprehensive corrosion management strategy. Overtime the popular car park had succumbed to structural damage and corrosion caused by the ingress of chlorides from de-icing salts from above.

Solution: This system comprised of 42 ICCP zones and 7 additional monitoring zones forlevels protected using surface-applied corrosion inhibitors. In addition to this, some 6000 C-Puck galvanic anodes were used to protect newly repaired areas to 2 levels. All the anodes and monitoring could be controlled and data accessed remotely throughoutthe car park with AchillesICP and AchillesIES, helping to extend its service life for 100+ years.

Outcome: This ESG compliant approach meant there was no need for demolition or extensive reconstruction using new materials, helping to reduce waste and harmful emissions. Reconstruction was also a near-impossible strategy due to underground facility and electric tram on land, meaning something non-invasive like cathodic protection was essentialto minimise social disruption.
