Structural Renovations have been working at Hallam House on Hallam Street since late 2018. The building is part of the Langham Estate portfolio and we have been working closely with the Estate’s Principal Contractor, Millane Contract Services and the Consulting Engineer, Jacobs.
The building is currently being refurbished and upgraded. In the basement plant rooms and brick vaults we have installed a new waterproof render using Flexcrete materials. Concrete repairs and anti-carbonation coatings have been carried out within the rear lightwell to the window heads and cills.
Internally, the existing lift was removed, and we were required to carry out extensive repairs to the staircase that wraps around the lift core. Existing supporting steel work was cut out and the landings and strings were repaired back to the original surface profile as required by the contractor installing the new glass lift.
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 secured a leak sealing project within the basement of a residential complex in Central London, using Sika repair products.
The basement has been converted into secure storage, which is being managed by a private company.
A large number of the movement joints within the slabs, which were constructed in the 1970’s, have perished and failed allowing water to percolate through into the storage units causing damage. It was not possible to access the top of the joints, as they have been landscaped.
After preliminary discussions it was agreed that all works would be carried out from within the basement.
The works involve the preparation of the concrete either side of the joints using specialist grinding equipment fitted with dust suppression and collection preventing damage to adjacent areas. Once complete the existing sealant and compressible boarding within the joints is to be removed and the joints cleaned. A new polyethylene backing cord will be installed and the shoulders of the joint are to be primed and sealed using a polyurethane sealant. To further enhance the waterproofing of the joints SikaDur Combiflex, an elastic membrane, is installed fixed with SikaDur 31, a moisture tolerant epoxy resin, across the joints leaving the centre free to move with the structure.
This robust solution can be applied in vertical joints, tops of decks (assuming it will be buried) and overhead.
Structural Renovations have recently completed waterproofing works at the Port of Tilbury on the site of the Tilbury Green Power Project.
Powered by waste wood material, such as that from construction sites, the facility is expected to generate 300 Gwh of green electricity per year – enough to power more than 80,000 homes.
Structural Renovations were employed to apply Flexcrete waterproof materials within the storage pit of the wood chip storage building. Flexcrete Cemtitious Coating 851 has been applied to the junction of the concrete slab and walls to prevent future water ingress to ensure the stored materials remain dry.
Following the successful completion of Phase 1, Structural Renovations Ltd have recently commenced work on the remaining 5 phases of external repair, decoration & window replacement to the grade II-listed Edwardian Beaux Arts Building in north London.
Originally built in 1909, the former Royal Mail administration building was transformed into an award-winning development of 180 luxury loft apartments and duplex penthouses.
The works require scaffolding to the whole building to provide access to carry out both concrete & brickwork repairs, protective coatings, window replacement and painting & decorating.
Further painting & decorating is being carried out to the penthouse buildings as well as application of liquid applied membranes to their roofs.
The works are planned to be completed during the summer of 2017.
There are 14 Ronald McDonald Houses across the UK, all located close to specialist children’s hospitals. They are open 365 days a year and are equipped with everything you would find in a family home. Families can get a good night’s sleep, prepare their own meals and feel at home, knowing that they’re only a moments away from their child.
Structural Renovations have been awarded the sub-contract for the installation of the Sika LPL warm roof system consisting of tapered insulation & liquid applied membranes offering a 20 year warranty.
The main roof, in excess of 600m², is now complete. Insulation & membranes to the two lower terraces will follow later in the year, one of which will have a green roof garden.
