Protecting heritage while strengthening infrastructure remains a core focus at CRL. We are currently delivering a major restoration project at the prestigious Gotham Hotel, a Grade II listed building in the heart of Manchester city centre.
The 1930s steel-framed, Portland Stone-clad structure has been affected by Regent Street Disease, a corrosion-related issue where the expansion of deteriorating embedded steel causes cracking in the stone façades. To address this, CRL is installing a comprehensive Impressed Current Cathodic Protection (ICCP) system, designed to extend the life of the steel frame by up to 60 years.
The project has been split into four phases across 16 zones with a completion date due in March 2026. The ICCP system includes reference cells, monitoring probes, T.R. monitoring and control units, anode ribbons, and multi-core cables all working together to provide robust protection against future steel corrosion. To facilitate installation, mortar joints have been raked to a depth of 50mm and widened to accommodate the anodes and field cabling.
Because the building is listed and fully occupied, the project requires a careful, collaborative approach, with CRL working closely alongside our key specialist subcontractors to complete the repair works.

Extra care has been taken at every stage, from the careful removal of original materials to meticulous colour-matching of mortar, ensuring repairs blend seamlessly with the aged façade. A detailed survey was conducted to assess the condition of the stonework and identify cracks requiring specialist attention. Extended-height scaffolding and screening maintain occupant privacy, while industrial-grade dust extraction and respiratory protection systems safeguard both workers and residents.
Electrical power connections have been coordinated with nearby commercial units, including a restaurant, to minimise disruption and maintain safe access.
This restoration project not only safeguards the structural integrity of a Manchester landmark but also demonstrates the effective application of ICCP technology in heritage conservation.
