Structural Renovations Limited were recently employed as a specialist sub-contractor to complete various remedial works to a number of buildings across the South Kensington Campus. Due to programming issues our works were phased to include two separate visits.

Phase 1 of the works involved masonry stabilisation and modified render repairs to both the Huxley Building, 180 Queens Gate and the Blackett Laboratory, within the main campus.
The masonry stabilisation aspect of the works involved connecting the internal and external leaves together, using proprietary stainless-steel ties, dry fixed into each leaf. We also connected brickwork and blockwork to the reinforced concrete slabs using a different proprietary tie set in a 2-part epoxy/cementitious grout.

Modified render repairs were then carried out where the existing sand and cement materials had failed due to a lack of provision for movement. Joints were also formed to allow for future movement, which were sealed using a 1 part polyurethane joint sealant.

Phase 2 saw us return to site and carry out stone remedial works to 58 Prince’s Gate. This involved the localised removal of spalled and defective areas of the previously painted stone façade, preparation of the substrate, and subsequent reinstatement to the original surface profiles, using proprietary polymer modified mortars.
