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.
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.
External concrete repairs and coatings have recently been completed by Structural Renovations at The Charterhouse School near Godalming.
The school was established in 1611 in London and moved to its current site in 1872. Since then buildings have been added, including the 2 storey Art Studio constructed in the 1970s, to accommodate the growing numbers of boarders
Following previous successful works to the swimming pool, budget figures were provided for the external concrete repairs and corrosion control to the Art Studio. Subsequently the contract was awarded for completion during the school holidays.
The ground floor concrete frame and soffit to the first floor cantilever slab were pressure washed and concrete repairs carried out using the Sika MonoTop repair mortars. Margel capsules were installed as a vapour phase inhibitor, followed by the application of a SikaGard water based elastomeric coating to provide a uniform protective coating.
Other works of a decorative nature were carried out to enhance the aesthetics of the completed works.
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.
Structural Renovations are currently working at Safestore’s Acton premises. The building is undergoing major refurbishment which includes adding a full height extension and over cladding of the full building envelope to bring the property into line with Safestore’s corporate identity.
The building is steel framed which has been encased in concrete with pre cast concrete window heads and cills. Structural Renovations are carrying out the removal of defective render and concrete and reinstating with mortars from the Sika MonoTop range, prior to the over cladding by a specialist sub-contractor.
To fall in line with the clients budget Structural Renovations are carrying out a visual and hammer survey in conjunction with the Principal Contractor, New World Builders and the Consulting Engineers, GGP Consult, to identify the extent of defective render and concrete on an elevation by elevation basis. A repair strategy is then proposed based on the findings prior to the works being carried out.
The works are accessed from scaffolding provided by the Principal Contractor, with exception to the front elevation where mobile elevated works platforms are to be utilised. Access here is limited and required to be maintained at all times to allow access to Freshway’s distribution yard at the far end of the site.
Structural Renovations are currently employed to carry out concrete repairs to the old YMCA building on the Barbican Estate that is currently being converted into apartments.
Following the successful completion of surveys and colour matched structural repairs to a number of structures on the listed Barbican Estate, Structural Renovations carried out a brief condition survey of the building prior to taking over by the developer. A further in depth survey was carried out and we were subsequently awarded the repair package.
Repairs are being carried out using the specification developed for the Barbican Estate repairs consisting of a Remmers high build structural repair mortar and finished with colour matched decorative mortars and a clear coating to replicate the brutalist finish of the 1960s & 70s.
