Furze Platt Senior School


Structural Renovations have recently completed a large concrete repair and coating project at a senior school in Maidenhead, Berkshire.

Furze Platt Senior School is a mixed school, with 1,250 pupils, which opened in 1963.

The School is comprised of multiple flat roofed, concrete framed buildings of varying heights, typical of the period they were constructed.

We surveyed the buildings in 2016, in order to provide the Governors with budget costings, which allowed them to apply for the required funding, which was awarded to them in May this year.

Originally it was planned that the works would be phased over 2-3 years but the decision was made to complete the entire project in a single phase, during the summer holidays.

A significant amount of scaffolding was required to the 21 elevations being repaired, which necessitated us mobilising prior to the closure of the School, whilst the pupils and staff were still present. Extreme care had to be taken to ensure pupils and staff were excluded from working areas and designated safe routes were implemented.

Once the School closed we commenced our works, which involved hammer testing and close visual inspections, prior to breaking out, square cutting, cleaning reinforcement and reinstatement using  Flexcrete Technologies specialist repair mortars.

Following the repair process, all concrete was pressure washed and subsequently coated using Flexcrete Technologies pigmented anti-carbonation coatings.

In order for us to hand the School back in time for the beginning of the new term we were required to work both weekdays and weekends, at all times liaising closely with the School’s facilities team.

Although tightly constrained by time we completed the project as planned and in line with the budgeted funds.

East Gate, Harlow


East Gate, Harlow - Waterproofing

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.

Edinburgh House


Edinburgh House

Structural Renovations have recently completed the 1st phase of structural repairs to a late 1960’s office block in South East London. Edinburgh House is currently being completely redeveloped as part of a £16m project that will provide 6,500m² of space. Once complete the building will be used as a flexible working environment for start-ups, through to large organisations, the clients’ ethos being, to provide a community in which people can network and collaborate.

Our works have included surveying the concrete slabs, columns and walls, followed by extensive concrete repair. The repairs were completed by both hand and pourable techniques, using Fosroc repair products, where the finish will be left exposed as part of the design scheme.

We will remobilise in September for the 2nd phase, which will include major poured repairs to redundant service voids in the ground and lower ground areas.

Local Government House


Local Government House - Concrete Repairs

Structural Renovations are currently employed at Local Government House, 10 storey office block in Smith Square, SW1.

Transport House, as it was originally named, was officially opened in May 1928 and was the headquarters of the Transport and General Workers’ Union, the Labour Party, the Trades Union Congress, and the Workers’ Travel Association.

The original building is now called Local Government House and houses the headquarters of the Local Government Association and a conference centre and is undergoing a major refurbishment which involves the removal of all existing partitioning and finishes.

Structural Renovations are employed to carry out concrete repairs to the concrete floor slabs, following a detailed survey carried out by Peter Brett Associates.

Large voids which have been formed where the concrete slab has been broken out along a diagonal fractures between the filler joists are being reinforced with 16mm diameter ‘L’ shaped reinforcing bars and filled with C40 concrete. Smaller voids such as redundant service holes are filled with Fosroc Conbextra HF.

Defective concrete has been removed from the filler joists. The exposed filler joists have been cleaned and primed, followed by the installation of an expanded metal lathing, the concrete cover is then reinstated with Fosroc Renderoc HB.

Morgan House


Morgan House

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.

The Beaux Arts Building


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.
