Terry’s Chocolate Factory (2015)

LOCATION: YORK

The former Terry’s Chocolate Factory in York, UK which was facing severe structural degradation due to the ingress of moisture and water over its near 100-year life. As moisture and water leaked into the fabric of buildings, it destroyed protective coatings and developed into corrosion of the structural steel frame. This eventually resulted in the tensile forces cracking and moving/ cracking of the brick skin.

A sustainable ICCP system as part of a £50million redevelopment to 180no high-end apartments helped to control and prevent future corrosion for the mortgage holders, the space was successfully regenerated, increasing the service life to another 100+ years and the assuring the value of the asset.

Product / System Used

LoCem® +point® ICCP system, alongside embedded CP200 corrosion rate sensors which allowed control and service life tracking through AchillesICP network management system and AiMS reporting facility.

Project Details

With the property being vacated throughout the redevelopment the +point® and +chase® anode mortars were installed internally within chases to protect internally facing steel and webs with discrete anode holes drilled deeper to protect the front face of the steel frame.

The anode system is controlled in 25-zones (5z per level).

The external appearance has been unaltered by the use of the ICCP and enhanced with the repair of the brick façades.

Project Impact

Building’s service life is extended for another 100 years with this cost-effective, non-disruptive installation of ICCP system that preserved aesthetic of the building. The use of LoCem® +point® meant the project was sustainable and ESG compliant – embodied carbon of the building has been retained and the materials used (LoCem®) reducing CO2e of the mortar by over 90%.

Data is uploaded to AiMS for control decision making and performance reporting with service life underpinning the 25-year warranty and resaleability of the apartments in the future.
