Reinforced Concrete Cladding Repairs

Brief description

Mercury Construction were appointed to address concerns about the structural integrity of the reinforced concrete cladding panels at a leading UK operational centre. Extensive investigations revealed deteriorated asbestos-containing mastic sealant between the panels, which had allowed water ingress, leading to the failure of dowels and lateral restraint fixings.

We had to overcome challenges with the asbestos-containing mastic sealant between the cladding panels that had deteriorated, requiring careful removal and replacement.
The building remained fully operational throughout the project, requiring careful planning to avoid disrupting daily operations. Limited access areas required innovative solutions, including the use of MEWP (Mobile Elevating Work Platforms) and IRATA rope access techniques for areas not reachable by scaffolding.

Throughout the project ensuring the safety of building occupants and workers was paramount, especially when dealing with heavy lifting operations near underground services, including a 1m diameter water main and a redundant underground storage tank.

Concrete panel repairs included refixing the concrete panels to the North East and North West elevations. Conducting concrete repairs and securing the “M” type panels, as well as installing three “C” type panels.

Mercury Construction successfully completed the project, addressing the structural integrity concerns of the reinforced concrete cladding panels while maintaining building operations. The project was delivered on time and met the high standards expected by the Client, ensuring the safety and functionality of the operational centre.
