"roof screeds"

Technical representatives from F. Ball have provided flooring with a cost-effective alternative to completely removing and replacing a weakened screed as part of a flooring refurbishment at the Aberystwyth Arts Centre, part of Aberystwyth University. Upon removing old floorcoverings, flooring contractors were faced with an extremely rough screed with weak patches, possibly the result of poor installation or curing techniques, environmental factors or age, that was unsuitable for the application of subfloor preparation products and the installation of floorcoverings. Some weak sections were mechanically removed, leaving about 75mm thickness to be made up. A structural engineer confirmed that the concrete bases were, otherwise, structurally sound. New P5 chipboard was affixed to the wood subfloors with screws and glued at the joins. It is often necessary to completely remove and replace a weakened screed. However, F. Ball technical representatives called upon to conduct a site assessment were able to recommend a less costly and time-consuming solution to make the surface suitable to receive floorcoverings, including quickly raising the level of floors where sections had been mechanically prepared. Firstly, any remaining weak spots in the base would need to be removed by mechanical means along with any surface contaminants to create a clean, sound micro-textured finish. Any dust and debris should also be swept away. Moisture tests indicated subfloor relative humidity (RH) levels in the concrete subfloors were as high as 78%, meaning a moisture management solution would be required. Contractors therefore applied a single coat of Stopgap F77 solvent-free epoxy waterproof surface membrane over the entire area to obtain a continuous barrier against subfloor moisture. Flooring contractors then used Stopgap 600 Base deep section levelling compound to raise the level of floors where weak patches of screed had been removed.  It was also recommended that the chipboard over the raised access floors was checked to ensure that the surface was clean, secure and undamaged before applying a minimum thickness of 0.2mm of Stopgap Fill and Prime over the entire area.  The whole subfloor area was then capped with a layer of Stopgap 1200 Pro high performance levelling compound to create a perfectly smooth base for the receipt of new floorcoverings. The final phase of the refurbishment was to install Nora rubber sheet floorcoverings using Styccobond F48 PLUS. 

Twickenham Studios was established in 1913 and is one of the UK’s oldest and most celebrated film and TV studios. The Lounge is the Studio's new rooftop bar. This fabulous facility is accessed through brand new Clement steel screens. Made from strong EB24 steel sections, they are robust, but also incredibly slim and elegant. The bespoke doors have genuine T bars and a high glass specification, including Guardian Sun Guard offering solar protection and an argon gas filled cavity which improves thermal efficiency.

The Challenge was To pump screed 47 floors up in a ‘single pump’ operation. And to lay 1800m2 a day for the Shangri La Hotel section of The Shard. 40mm Gyvlon SKY on a resilient layer to part E, pumped internally in the building to allow the glass cladding and other operations to continue. Single pump operation at 14m3 per hour up 200 metres

21 Moorfields is a new commercial development in the City of London made up of offices and high-quality retail space. The building sits directly above the London Underground and also a new Crossrail ticket hall. A selection of our specialist screed products was specified for use on this complicated project due to the high strengths gained at a low depth and fast-drying properties.

The building was constructed using ICF blocks that are to have a rendered finish. Internally the ground floor is a concrete slab and the upper floor has timber posi-joists with the Lewis Deck and resilient strips laid above. 16mm underfloor heating pipes are then clipped into our new clip rail system with a free flowing screed then poured on top, 50mm thick. This then gives 20mm cover to the heating pipes, maximising the efficiency of the whole system.

This self-build project was looking to improve the quality of the 1st floor construction, eliminate any danger of floor creaking that is common to timber floors and include an efficient underfloor heating solution.Underfloor heating work at its most efficient when it is installed within a screed, this is the way ground floor system are installed and being able to replicate this pipes in screed arrangement upstairs makes sense for the performance of the complete system.Also, by including some stiffened mass to the upper floors, the feel of the floor is replicated from the ground floor and also provides some very useful solar thermal buffering to keep summer temperatures under control in a building technique that otherwise has very little mass to to achieve this, especially on the upper levels.A timber frame structure requires the floor to provide racking to prevent the building from twisting. Meaning the floor needs to be secured to the joists below so the floor can stop twisting. There are 2 ways of installing Lewis Deck in timber frame structures. Firstly is to fix the Lewis Deck down or, alternatively, fix a timber deck on top of the timber joists and the Lewis is then laid loose on top of the timber with the resilient acoustic strips in between , thus, further enhancing the acoustic performance of the floor.

Providing 21 affordable homes in the first ‘carbon negative’ housing community of its kind in the UK. The initial concept began in 2009 with the aim of creating carbon negative housing. The project is ground breaking with a plan to lock away as much carbon as possible whilst generating excess energy from systems installed.Lewis Deck light weight steel/ screed composite floor system providing acoustic floors improving Building Regulations Part E standards by at least 8dB was installed in the apartments.This project achieved a Zero Carbon certification under the Code for Sustainable Homes and achieved Passiv Haus standards, but was not certified under this system. The performance was monitored by the Technology Strategy Board (TSB) as well as how the social tenants found the experience of living there given the lifestyle adjustments that were needed.The Lewis Deck was used as it achieved the enhanced acoustic and fire performance required in this project, especially given that this was a timber frame development. The elements of the building also had to achieve an A+ Green Guide to Specification rating from the BRE, this was achieved by using a liquid screed on top of the deck that contained a high recycled content.The project won a number of awards and was marketed as the UK's 1st "Carbon Negative" social housing scheme.

60 London Wall is an icon mixed use office & retail building in the dynamic heart of London’s City, with 328,500 sq ft of grade A office accommodation situated over ten stunning floors. It was recently completely renovated and Alliance Bernstein now occupy space within the building. The existing raised access floor was overlaid with Knauf GifaFloor FHB18 making it the ideal substrate to receive a combination of ceramic tiles & micro-screed cement

During the regeneration of the new Terminal 2 at Heathrow Airport, Vetter UK, the specialist contracting arm of Laing O’Rourke needed to specify a fast-drying 135mm deep screed so that the project could continue with minimum disruption, saving time and costs. RonaScreed FastDry Prompt was specified for its fast-drying properties and the fact that it could be mixed at ground level and then pumped up the three storeys to the point of application, saving on time and cost.

Client: Cheval ResidencesLocation: Edinburgh, ScotlandSector: Hotel, Leisure & HospitalityYear: 2021Project Size: 150 m²System: vebroscreed Renovatevebroscreed Renovate, from Vebro Polymers, bonded to marine ply and concrete, has been installed across the ground floor reception and concourse leading to the bar area and restaurant.vebroscreed Renovate is a single part, fibre reinforced, cementitious smoothing underlayment screed, incorporating a blend of graded fillers, fine cements, and polymers, with excellent flow properties. The material is mixed with a cold-water addition to deliver a fine flow slurry that can be both pump and pour applied. The material has been used to level the existing concrete surface prior to the installation of terrazzo and ceramic tiles, which have been chosen in keeping with the listed building’s new interior scheme. Incorporating a specially formulated fibre technology, vebroscreed Renovate aids application and strength resulting in a strong, sound and even base that is ready to commence the tiling process after only 8 hours.All screeding on site has now been completed and the site turned over to the tilers, who are on track to complete ahead of building’s opening in a matter of weeks and to coincide with Scotland’s relaxation of international travel restrictions. 

This new-build house was in a remote location and off-grid for mains gas, the house was to be heated by a heat pump and so efficiency was a major consideration for the project. The Lewis Deck system was chosen for the 1st floor of the building to provide the same efficiencies for the underfloor heating as the concrete ground floor as well as providing a high level of acoustic separation for this quality timber frame project. The build-up included the Lewis flanking and resilient strips, Lewis Deck, Anhydrite liquid screed and underfloor heating pipes.

The project involved the conversion of the 1st floor of the Grade II listed Princes Building in Newcastle’s Quay side area into 10 apartments. The building, which was designed by William Parnel, who was responsible for some of the best architecture in the City, was built back in 1863 and as such posed some interesting problems when it came to bringing the building up to current standards. The introduction of the Lewis Dovetailed Metal Deck and screed system on top of the existing joists provided the necessary performance for airborne and impact sound and fire separation.

The new 3,100 m² resin floor at the Honda Import Centre, installed by Resin Floors Telford, features a robust and seamless finish using Arturo's high-build resin coating. The installation process included extensive surface preparation and remedial repairs to allow an industrial top screed to be applied before two coats of Arturo EP3900 high-build coating compound were applied for durability and a gloss finish. The project resulted in a highly durable, aesthetically pleasing floor that exceeded client expectations.

A Mapei system of flooring products has been specified as part of a major refurbishment at the Imperial War Museum. The historic museum is being sympathetically transformed to mark the centenary of the First World War. Mapei’s high performance cementitious flooring system, Ultratop, was chosen to complement the exhibits and provide low maintenance, coupled with resistance to heavy pedestrian traffic. Mapei’s flooring system was specified throughout a 5,000m2 floor area. The system combined Mapei Topcem rapid-drying screed, Primer SN and Ultratop - a technologically advanced self-smoothing cementitious floor in Anthracite.

Ronafix Pre Packed 6-50mm was used during the development of the Tottenham Hotspur Stadium in 2017 to provide a thin section, heavy-duty screed capable of taking traffic in excess of 60,000 on a weekly basis. The Tottenham Hotspur Stadium is the third-largest football stadium in England and the largest club stadium in London. The entire construction cost exceeded £1 Billion. It is a multi-purpose stadium and features the world's first dividing, retractable football pitch, which reveals a synthetic turf field underneath for NFL London Games, concerts and other events.

Wallbarn worked with a specialist tile installer, working on a new-build in Carmarthenshire. Initially 600mm deep concrete screed was used for a base, but the weight bent the lintels. The concrete had to be broken out and the whole deck repaired. The installation was challenging with falls over 250mm across the deck. ‘Balance’ self-levelling adjustable pedestals provided the answer. Using bespoke pedestal planning software, MegaPro, the Wallbarn service team was able to work out the exact quantity and height of pedestals required for the scheme, colour-coded on the drawing, guiding installers on where to place each pedestal.

This major redevelopment of Charlton Park Academy school involved replacing temporary mobile classrooms and a single storey building with a two-storey steel framed brick building to better meet the needs of students, teachers and carers. A structural flooring solution was required for use over precast planks, covering 800m2 on the ground and upper floor at a depth of 75mm to 120mm. Space and access would be challenging, due to the small footprint of the site, proximity to the existing school building and access from a busy main road. Given the large floor area, a traditional sand cement screed would have been very time consuming to place. Tarmac’s TOPFLOW SF a self compacting steel fibre reinforced concrete was chosen as the solution. Its flowing nature would allow it to be quickly pumped into place and adapt to the variable thickness criteria. TOPFLOW SF is designed to act as a structural topping with both, steel mesh & fibre reinforcement. The steel fibres added to the TOPFLOW SF gave its robustness and flexural strength as it was being placed over a precast plank system that could flex with loadings. They also reduced the risk of cracking. By replacing steel mesh reinforcement, it helped avoid problems with access, storage and handling and kept the site open for parallel trades. Using TOPFLOW SF rather than a sand cement screed or reinforced concrete, improved productivity and saved time. This saved 13 days or just over 2.5 weeks on the programme.

F. Ball products have been used to install vinyl and rubber flooring, as part of the refurbishment of the Wellington College fitness centre, in Berkshire. Flooring contractors were called to install luxury vinyl tiles and rubber flooring. After removing the existing floorcovering, contractors built up the raised platform with timber and plywood and applied Stopgap 1200 Pro smoothing underlayment over the raised platform and the screed subfloor. Styccobond F49 Hybrid PS temperature tolerant vinyl adhesive was then used to adhere the floorcoverings. The adhesive enabled contractors to successfully install luxury vinyl sheet, wood effect planks, plus the rubber flooring.

A range of F. Ball products have been used to deliver a high quality, long-lasting floor finish in Plaisterers Hall, as part of a refurbishment following flood damage. Contractors first applied Stopgap P131 general purpose primer over the subfloor, to seal the entire area, and to aid adhesion of the smoothing underlayment. Once the primer had dried, contractors applied two component smoothing underlayment Stopgap 1200 Pro over the entire screed. Styccobond F3 water-based rubber/resin flooring adhesive that has excellent wet grab with an early build-up of strength, was used to adhere the carpet to the subfloor.

High performance subfloor preparation products from F. Ball have been used in a major housing development in London. Firstly, a moisture test was taken which indicated that the sand/cement screed subfloors were dry enough to proceed with the installation. After priming the surface with Stopgap P131 primer, contractors applied Stopgap Green Bag 114 at a 3mm thickness to smooth out any undulations. Stopgap Green Bag 114’s fast setting and high strength properties made it ideal for this development as it dried quickly and was strong enough to withstand heavy-duty foot traffic once work restarted.
