Located in the heart of Chelsea, close to the trendy Kings Road, this multi-storey block, built in the 1930’s, was for some time used for military purposes and now consists of 42 private flats. Over the years, numerous efforts have been made to deal with cracking masonry caused by a rusting steel frame. Historically this was done by dismantling the defective masonry and undertaking remedial works to the steel.

In 2020, Stone Edge Conservation were appointed to install a bespoke cathodic protection system. Whilst it was still necessary to dismantle some of the masonry and replace steel members that were too badly corroded, the introduction of a cathodic protection system, that passes an electric current through the frame to prevent corrosion, will help to futureproof the structure against the need for extensive and expensive rebuilding.

Working in tandem with the designers, C-Probe, our operatives are fully trained in the installation of this intricate system. Where investigations revealed extensive loss of steel integrity a temporary works support system was installed to allow the dismantling of the upper floor. Once reconstructed, new correctly sized cappings were installed and a roof coating applied.
