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.
Structural Renovations have recently completed works to install a reinforced liquid applied membrane to the concrete canopies over the shops on East Gate, Broad Walk, East Walk and Terminus Street in Harlow. The works also included concrete repairs and masonry stabilisation.
The works were carried out in two phases, in the first phase included the application of a reinforced, solar reflective coating to the canopies and concrete repairs and the introduction of expansion joints to the soffits. The top surfaces of the canopies were cleaned and then primed with Flexcrete Bond Prime, followed by the application of Flexcrete Roofdex HB reinforced with Flexcrete Cemprotec GFM 100. Concrete repairs to the soffit were carried out using Flexcrete Monolite. Finally expansion joints were installed, using Fosroc Nitoseal MS60, at regular centres to help prevent future cracking.
The second phase of works were to install Helifix DryFix ties into the large decorative panels on each corner of the building. This was to ensure there was a connection between the decorative panels and the underlying substrate. Following our installation the panels were subsequently rendered over by others to provide a uniform finish.
Structural Renovations have recently completed masonry repair works at the West Reservoir Centre in Stoke Newington, North London.
Fractures had developed adjacent to the large openings of the main tower building. A specification was developed to reintroduce the structural integrity at these locations using a combination of Helifix HeliBars, CemTies and CrackBond TE.
The building remained in operation throughout and the scaffold was specifically designed and installed so that none of the scaffolding was at ground floor level. Instead the scaffold was erected from the existing steel beams.
As part of the hotels major refurbishment Structural Renovations have been awarded the contract to undertake external repairs and waterproofing of the concrete surfaces.
This large imposing hotel overlooks the English Channel and the harsh coastal environment has been a major contributory factor to the defects identified.
Concrete repairs were carried out to the balcony edges and detailed cornicing using a hand-placed repair mortar, Sika MonoTop 615 primed with Sika MonoTop 610.
Failed coatings were removed from deck areas, such as balconies and a new liquid applied membrane was applied using Sikalastic 625 accompanied by a 20 year guarantee for the completed works. Existing movement joints were replaced with Sika Hyflex 250 Facade.
Additional phases are due to commence later this year.
We are currently completing the full external refurbishment of a 1960’s residential block in Surbiton, Surrey.
The existing asphalt roof has been over coated with a reinforced, seamless liquid applied roofing membrane and the cantilevered reinforced concrete balconies have been repaired using a cementitious, polymer modified system before being treated with a reinforced polyurethane membrane on the decks and pigmented, anti-carbonation coating to the soffits.
Other works include, refurbishing the communal electrics and plumbing, installing new uPVC facia to the perimeter of the block and three tank housings and upgrading the TV aerials to all the flats.
This contract demonstrates our capability of co-ordinating multiple trades, where the interface between various elements demands close monitoring of programming.
If you own, manage or live in a similar block of flats that you feel needs remedial work, or simply require advice and outline costings please contact our head office by telephone or email.
We are currently working at Imperial Works in Kentish Town. The Gothic style brick structure is the former home to the Imperial Piano & Organ Company.
The warehouse has previously been converted to offices & is now being refurbished & upgraded.
