"permanent formwork for arches"

As one of the pioneers of remote working solutions, Citrix recently chose to reconfigure their offices, taking on an additional space at the Cambridge Science Park. Aiming to create an environment that would facilitate engagement, creativity and productivity, moveable wall specialists, Style worked closely with architect, Gensler, and contractor, Area Sq, to offer intensely flexible workspace.Delivering exceptional acoustic ratings of 55dB and 52dB respectively, Style installed two Dorma Hüppe Variflex solid moveable walls and a single Variflex glass moveable wall, allowing Citrix staff to section off a meeting area from the main hall and then further sub-divide the space as required. Contributing to the vibrant new décor, all walls feature black RAL 9005 profiles and dry wipe magnetic boards to encourage brainstorming. Cambridge Science Park has been home to the UK Citrix Research and Development team for over a decade. Having occupied approx. 30,000 sq ft of space on the first floor, Citrix was keen to refurbish their existing workplace as well as expand operations by taking over additional space on the ground floor.Reflecting the Citrix vision and culture, the new layout and design maximises the potential of the space, allowing staff to establish new ways of collaborating.When all three walls are in place, three smaller meeting rooms are created. Alternatively, a combination of one large and one small meeting room can be formed, or just one very large space using just the glass moveable wall. The entire space can also be opened-up into one large open plan area. “This is an excellent example of how a combination of glass and solid moveable walls can create really adaptable office space,” said Steve Williams, sales director for Style Midlands.“Thanks to the inclusion of three pass doors, access is simplified and also allows the glass wall to be left in place for extended periods if desired, creating a more permanent space. “However, due to the semi-automatic operation of these operable walls, they can be opened up extremely quickly so that the entire space can be reconfigured for different vents throughout the day.” 

Once known as a local police station, Westbourne Place was eventually converted into a lavish building with an add-on in the rear. Developed by Redrow, the building retained a number of details from its original design, such as high ceilings and period features. It even remains connected to what was once the police station’s parade ground and is now a scenic and serene courtyard.Still, the building itself is anything but stuck in the past. Redrow’s conversion gave the Westbourne Place more modern features as well. These include fully fitted contemporary kitchen units and engineered oak flooring. All of which benefit the 49 luxury suites there. Those who reside in any one of them will not only enjoy those features in a one-, two-, or three-bedroom unit but will also enjoy the advantage of living within the heart of West London next to multiple transit, taxi, and cycling areas.Of course, to make any of this possible, Redrow needed to restore Westbourne Place efficiently. For that to happen, it was vital that they find a concrete waterproofing solution that would be low-maintenance, set no limits on concrete pouring, and have an easy installation process.SolutionWhen considering a solution that fit all those requirements, the contractor for Westbourne Place decided on KIM as their desired form of concrete waterproofing. As a result, they used 1,000 m3 (35,315 ft3) of KIM-treated concrete to waterproof the building’s basement parkade’s slab and walls. That allowed the contractor to build straight up to the property line and to save on the cost of application. It also allowed the KIM-treated concrete to self-seal if any minor cracks occurred in the concrete and to block water from passing through the concrete, reducing the need for maintenance.For further waterproofing protection, the contractor applied Krytonite Swelling Waterstop and Krystol Waterstop Treatment to all the construction joints and details. With this dual-protection waterstop system, the contractor could ensure that no leaks would occur and that water would not be able to infiltrate the concrete and corrode the steel rebar within. Moreover, this system and KIM will work for the life of the structure, providing permanent protection.

Emma House, Romford, a residential apartment block built in 2007, needed a new waterproof membrane for the entire roof area after the single ply membrane, installed just 10 years earlier, had failed. The specification by our clients asked for a cold applied system to be used during the refurbishment to minimise disruption to residents, while providing a permanent waterproofing solution.The ChallengeCore samples taken of the roof build-up showed there had been extensive water penetration which required urgent remedial action. Impossible to repair, the complete roof system had to be stripped back to the roof deck by Proteus Waterproofing’s approved contractor. The approved contractor installed a new Proteus Pro-System® BUR (built up roof system) incorporating Proteus Pro-Therm insulation, to provide a new seamless roof – an area of some 150 square metres – offering a 20 year guarantee.Why Proteus Pro-System® was specifiedProteus Pro-System® was installed using no heat, providing a seamless waterproofing membrane on completion. Proteus Pro-System® is a high performance, seamless and cold-applied waterproofing membrane for flat and pitched roofs. It cures to provide completely seamless waterproof protection and has excellent thermal and UV stability, making it suitable for use in all climates.Proteus Pro-System® does not brittle, deteriorate or discolour with age. It uses atmospheric moisture to trigger its cure process and unlike conventional polyurethane systems can cure under water, without gassing or foaming. It also becomes resistant to rain damage and may therefore be applied in relatively poor weather, without any subsequent loss of performance or durability – making it ideal for Emma House.About Emma HouseEmma House consists of 14 one-bedroom and 19 two-bedroom apartments just minutes away from the centre of the market town of Romford, which offers shops, services and a wealth of bars and restaurants. When first built in 2010, Emma House offered young professionals an opportunity for affordable housing close to London and has remained at the forefront of the property market in Romford ever since.

The Park Hill Estate in Sheffield was built as a council estate between 1957 and 1961. It was designed by Jack Lynn and Ivor Smith in a brutalist architectural style and has always divided opinions.Described as revolutionary for its time, the concept was `Streets in the Sky` with wide deck areas and distinctive concrete frame.  Whilst demolition of the site was being considered, in 1998 the estate was listed by English Heritage and given Grade II* status which was considered very controversial and attracted much criticism.  It is the largest listed building in Europe and, with its protected status, it was decided to renovate and redevelop the site as a joint venture between Urban Splash and English Heritage.The future of the scheme was to develop the site into desirable upmarket apartments, business units and social housing and the success has been widely publicised, including features in almost all architectural and concrete magazines, with a shortlisting for the 2013 RIBA Stirling Prize & 2023 RIBA Yorkshire awards, as well as winners of the AJ Retrofit Awards 2023.The key involvement for KEIM Mineral Paints was renovation of the extensive concrete frame. The discoloured concrete gave a drab and dirty look to the building – not the desirable, upmarket effect that the designers were looking for. The first consideration was to paint the frame in its entirety but this would have led to the loss of what is considered to be the most iconic feature of the building. So the challenge was to renovate the frame, improve the colour and finish without creating a painted effect.The answer was to use KEIM Concretal Lasur. This innovative paint system is a colourwash or stain which is applied onto concrete to cover blemishes and enhance the appearance, whilst, most importantly, keeping the look of natural concrete. KEIM Concretal Lasur has all of the features integral to KEIM Mineral Paints such as a permanent and highly protective chemical bond, complete UV stability and resistance to mould and fungal growth.KEIM Concretal Lasur is diluted with a complementary product using differing ratios and opacities to achieve the required colour and coverage, whilst still enabling surfaces to look like unpainted concrete. The system can also be employed to minimise any unsightly repairs to concrete. The versatility of the system allows almost complete coverage of repairs, or slight coverage, if preferred, which enhances the natural look of the concrete but gives the effect of a more visually appealing finish.

The design of spaces for children is intriguing because of the permanent influence it can have on them. A new online theme by Danish acoustic panel manufacturer Troldtekt explores through articles and expert interviews how good acoustics plays its part when designing these areas. Of course, other factors such as colour, shapes, robustness and finish also have an impact but so does sound. Children are noisy and active and the rooms they inhabit are typically large. Careful design considerations are particularly important because a child’s environment moulds their perspectives for the future and the development of the mind and body. School, activity and childcare spaces all affect self-esteem, performance and friendships and help shape the individual into the adults they will become. Studies such as Bronzaft and McCarthy (1975) have shown the effect noise has on wellbeing and learning - This is the reason why the products of specialist manufacturers like Troldtekt are specified to solve the problems of noise and reverberated sounds. If acoustic absorption is ineffective, discomfort and irritation will result from the reverberations. If it is designed well, the participant’s interest will increase, as many case studies for new and transformed buildings prove. In an interview with Troldtekt, the Danish education psychologist Mille Sylvest comments, “It’s very important to be aware of noise when designing facilities. Noise affects stress levels for both children and staff because nobody can endure spending long periods of time in a noisy environment. Lower energy levels, more sick leave and poorer learning outcomes are the direct results of noise.” Specified throughout the UK and Europe, the benefits of 100% Troldtekt natural wood wool panels include high sound absorption, high durability, natural breathability, low cost life cycle performance and sustainability. This high performance is recognised by their Cradle to Cradle certification at Silver level. Available in various sizes and in four grades from extreme fine to coarse, the panels can be left untreated or painted in virtually any RAL colour. Samples, case studies and technical information are easily sourced from tel 01978 664255 or visit www.troldtekt.co.uk.

Brick manufacturer Vandersanden is launching the very first CO2-negative facing brick on the market under the name Pirrouet®. One tonne of Pirrouet® facing bricks absorbs up to 60 kg of CO2 during the curing process and throughout its lifespan. This breakthrough is due to a unique industrial application of carbonation technology. In addition, only 20% of the Pirrouet® brick consists of primary raw materials – the rest comes from residual flows from the steel industry. With this first in the construction industry, Vandersanden is ensuring that attractive facades can contribute to a smaller environmental footprint. “Vandersanden wants to be completely CO2 neutral by 2050. With this CO2-negative facing brick, this intended reality comes a big step closer,” says Darren White, UK Sales Director, Vandersanden.Vandersanden has launched the first CO2-negative facing brick, Pirrouet® in the UK. The brick is unique because it is not fired but cured using CO2 from other industries. During the carbonation process, the CO2 reacts with calcium-containing materials, creating carbonates. This permanent bond creates a hard, limestone-like brick that meets the European standard for ceramic facing bricks. It is the first time a facing brick has been produced in this way.The Pirrouet® brick is largely a circular product. It consists of as much as 80% mineral residues (carbinox and stinox) from the steel industry. These residual flows don’t end up in landfill but are sustainably recycled. Only 20% of the new facing brick consists of primary raw materials such as sand, water and any dyes.The new brick is not only a fine example of sustainability, but it also delivers on aesthetics. Vandersanden achieved this attractive result by giving the Pirrouet® brick a unique surface texture. It is available in 11 colours, giving every facade a unique and aesthetic look. “Years of hard work have gone into developing a CO2-negative and circular facing brick. This innovation brings us another big step closer to our promise of a CO2-neutral future, as set out in our sustainability programme, Together to Zero. We are therefore immensely proud of this achievement by our team. This facing brick is a milestone for our sector, and with it, we are contributing to more circularity and reducing the CO2 footprint in the entire construction sector,” says Darren White, UK Sales Director, Vandersanden.Capturing CO2 from factories for reuseThe most energy-intensive aspect of producing facing bricks is no longer necessary with Pirrouet®. Instead of being fired in a kiln, they are hardened in a CO2 chamber. To fill this chamber, Vandersanden uses CO2 captured from other industries. As a result, a waste product becomes a raw material again and less CO2 is released into the atmosphere. During the production process, each tonne of Pirrouet® facing bricks absorbs as much as 60 kg of CO2, which bonds permanently with the calcium hydroxide present during the curing. To complete the sustainable process, Vandersanden generates most of its green electricity via its own solar panels and windmill.Production started with slim facing bricks and the range will be extended with WF and DF sizes of bricks later this year.Towards a CO2-free futureThe innovations by family company Vandersanden are all part of its sustainability programme, Together to Zero. With this initiative, it is committed to making all its processes, production methods, factories and products even more sustainable. “We are not just doing business for ourselves. We want to contribute to solutions for the major challenges in our society and for this reason we have created Together to Zero. Vandersanden wants to be completely CO2 neutral by 2050. With this revolutionary facing brick, we are one step closer to achieving that goal. We also want to inspire others and we’re calling on all our sector colleagues to work together towards a neutral footprint. We challenge everyone to join this pledge,” commented Johan Deburchgrave, CEO of Vandersanden.The revolutionary Pirrouet® facing brick entered the Belgian and Dutch markets in 2023, to a positive response. The construction and equipping of the new Pirrouet® factory in Lanklaar is almost finished and the first Pirrouet® bricks have been delivered to the very first project to specify them, the pioneering Groen Nobelhorst project in Almere, in the Netherlands, where 60 sustainable homes are being built. “We didn’t choose the name of the brick, Pirrouet®, at random. We wanted to pay tribute to our former CEO, Pirre Wuytack, a visionary man who was the founder and instigator of this pioneering sustainable innovation. The name is also a reference to the 360° rotation, the circular, and represents a movement towards a CO2-neutral world,” comments Darren White, UK Sales Director, Vandersanden.To find out more about the innovative production process of Pirrouet®, visit the Vandersanden website here.

Our purposeAs one of the UK’s leading housing associations, the Guinness Partnership prides itself on providing high quality homes that meet or exceed current Standards. It is therefore committed to a continuous programme of maintenance and asset management across its 60,000 homes estate.As part of that process, the 13-storey 1980s-built Waverley Court in Crewe was due for refurbishment, including new windows and heating for the 95 flats therein. An initial survey highlighted that the 1200m2 roof was failing and in need of upgrade to maintain its weathertightness.Our in-depth roof report also identified that the insulation was below current standards. Safety on the roof for maintenance was also an issue: the existing handrail was originally erected as a temporary fixture, penetrating the waterproofing and providing inadequate rooftop security for working at height.Our solutionThe existing waterproofing had perished beyond useability. We advised complete strip of the existing back to the concrete deck, and building up a new thermally-efficient roof to meet current standards required under the Part L of current Building Regulations.Our TA-25 W Flat Roofing System for warm roofs was installed by Approved Contractor Everlast as sub-contractor to the principle contractor, Wates. To address the poor falls on the roof, the insulation was tapered to the perimeter. We achieved an overall roof U value of 0.17W/m2K, exceeding the current Regulatory requirement of 0.18W/m2K. In line with Safe2Torch guidelines, our self-adhesive system was used to detail around roof penetrations for extractor fans and similar plant.We highlighted and designed bridging details to maintain the fire integrity around compartment walls to comply with Part B3 of Building Regulations.We designed a new, permanent and safe handrail system. This is fixed to the brick façade of Waverley Court, avoiding any penetration of the roof fabric and thus maintaining its integrity and watertightness, whilst minimising maintenance requirements.“Langley’s expertise and attention to detail has enabled us to deliver on our ambition of providing homes that people want to live in. Langley’s performance has helped us provide a dry, warm, safe living environment that exceeds current Regulatory requirement. The independent insurance-backed guarantee covering design, materials and workmanship adds value to our long-term estate asset management.”

GRCA Full member Telling Architecture Ltd demonstrates how innovative 21st Century Modern Methods of Construction can be used to replicate 19th Century, Victorian inspired architecture. The key to authenticity when replicating historic construction methods or styles, is care and attention to detail. Get it wrong and at best you create a poor pastiche of a bygone era. This was the challenge presented to Telling Architectural that required them to develop further the techniques they have already established and utilised in the design and manufacture of brick faced GRC, to create convincing complex 3D forms.This £300 million project nestled between iconic 21st century London landmarks including Tate Modern and The Shard, comprises mixed use buildings that provide offices, shops, gallery restaurant and cinema adjacent to the historic and world-famous food destination Borough Market.This project identifies heavily and sympathetically with its Victorian past. Brick railway arches have been re-purposed to integrate with the facades of retained warehouses in addition to new contemporary architecture that is weaved in amongst connecting pedestrianised yard spaces that creates a refined reimagining of a bygone age.Telling Architectural Ltd continue to innovate and develop the capabilities of Glassfibre Reinforced Concrete. The addition of real brick facings provides the Architect/Specifier with a whole new range of possibilities that they can consider as a means to achieve their creative goals. There is a huge demand for the skills of a brick mason that can replicate the standard of detail and workmanship specific to this project. Unfortunately, as a result of an ageing workforce and low intake of new tradespeople, they are in short supply and come at a premium. The construction industry has had to evolve and adapt to find a solution to this problem, in addition to having to rethink its approach about the way we build. All these issues can be addressed and remedied by introducing off-site/premanufactured innovations that remove key elements off the critical path and in so doing deliver sustainable solutions in an on-time/just-in time basis.In most circumstances the go to solution would be to utilise traditional precast concrete, however using Brick Faced GRC provides significant savings in weight and use of raw material, which in turn can lead to further added benefits in both the extent of groundworks and design of the structural frame.  For Borough Yards London project, the challenge to fabricate masonry elements that include intricate features such as faceted columns utilising cant bricks, splayed sawtooth pattern beams with brick soffit returns, the term masonry cladding falls short in identifying what has been achieved on this project - this is façade engineering of an exceptional standard. Proof indeed of the opportunities Brick Faced GRC provides, not just for contemporary architectural styles, but also as a means to maintain and preserve a part of London’s Victorian Heritage.  Client: MB Bermondsey LtdMain Contractor: Wates ConstructionInstaller: LesteroseEngineer: EvolveArchitects: SPPARC ArchitectureScope of Work: 776m2 Brick Faced GRC Grade 18P

 Across Europe there has been a surge in the swimming pool sector. With many more people staying at home and foreign travel restricted both domestic and commercial pool manufacturers have seen a rise in new builds and renovation of existing pools. Trends indicate that 2021 will see a further rise in local markets as more people cocoon and less people travel abroad. Commercial pool operators are also seeing a rise in popularity and are taking the opportunity of enforced closures to update and renew existing infrastructure. In the UK it is expected that now Brexit has been finalised, investors in UK hotels, Spas and High-end residences will drive the wet leisure market further. In a new feature on their website, leading acoustic panel manufacturer Troldtekt summarises the knowledge, trends and examples which will help influence the design of swimming centres today and in the future.  The feature includes 16 trends compiled by the International Association for Sports and Leisure Facilities. These cover everything from economics and digital features to new uses and products which influence the architecture of pools and their construction. Pools can be used for different purposes and by quite different groups of people. This places demand on designers and developers to provide perfect layout and solutions to create the best atmosphere.  One interesting aspect is how modern swimming centres need to satisfy many expectations from different types of user. For example one pool needs to accommodate the needs of elite swimmers with those people wanting to exercise, young families and wellness enthusiasts. Each group is looking for a different type of experience and unless planned, there is a risk of friction between them. Architects such as GPP Arkitekter and Bay Arch have succeeded in this balancing act as shown in the newly built Frederikssund Swimming Centre.  One of the most important aspects and one universally agreed across all types of user is the control of noise. For example, absorption of the loud sounds from splashing, shouting and playing is essential. This is why Troldtekt’s acoustic wood wool panels are often specified because of their durability, appearance and are natural breathable meaning they will absorb and release moisture making them perfect for wet area installations. Manufactured from certified wood, a 100% natural material, and cement extracted from Danish mineral resources, they achieve high levels of technical and acoustical performance and can be disposed of harmlessly, breaking down in the soil.  Founded on the Cradle-to-Cradle design concept, the natural and inherently sustainable panels are available in a variety of different surfaces and colours and contribute to a building’s BREEAM, DGNB and LEED ratings. In addition to their high sound absorption and tactile surface, they offer high durability and low cost lifecycle performance. Available in various sizes and in four grades from extreme to coarse, the panels can be left untreated or painted in virtually any RAL colour. The theme is available at https://www.troldtekt.com/news/themes/swimming-centres/ or https://bit.ly/2LJJiGU while samples, case studies and technical guidance is available from tel 01978 664255 or Troldtekt.co.uk. 

Located between St. David's and Aberdour, the tanker terminal at Braefoot Bay is a base for the export of liquefied petroleum gas. The terminal consists of two jetties located on the north shore of Incholm Island. The gas is piped to the Mossmoran Plant in Fife direct from the North Sea, broken down to form ethane and then converted into ethylene, the basic hydrocarbon 'building block' of the petrochemical industry. The products are then piped the final three mile journey to the Braefoot Marine Terminal where they are fed into tankers and gas carriers for markets in Europe and the USA. The terminal is operated jointly by Shell Expro and Exxon.The jetty was suffering from increasing levels of deterioration of the reinforced concrete structure due to the relentless corrosive action of the marine salt environment on the reinforcing steel. A remedial plan was developed to carry out repairs and to introduce a cathodic protection (CP) system to greatly enhance the protection level and therefore extend the life of the structure. The plan was prepared by structural engineers from Shell, led by Hans Verheyde, and Balfour Beatty Construction Services UK (BBCS) was awarded the contract.Two major factors had to be accommodated within the repair programme. Firstly, the tidal flow that submerged the lower part of the jetty twice every 24 hours and secondly, the jetty is a fully live and very active transport hub and shipping schedules had to take precedence at all times. Round-the-clock flexible working maintained delivery of the twelve-month project.Saint-Gobain Weber's specialised repair concrete products were specified for the remedial actions on the Braefoot Bay jetty and technical application advice was provided for the active phase of the project. A suspended scaffold was designed and installed which allowed fast access when the tide ebbed so that productivity could be maintained. Traditional techniques were used to breakout the spalled and cracked concrete and to wash out the surface chlorides and clean the existing reinforcement steels.webercem five star repair concrete CP is a shrinkage-compensated, high strength, low resistivity, flowing repair concrete designed for use in conjunction with CP systems. This pre-blended cementitious concrete fully complies with the Highways Agency Specification Class 29F for high-strength flowing concrete for major structural repairs. It contains non-reactive aggregates with a low soluble-alkali cement content which is particularly important where CP is to be used. The rapid strength development and dimensional stability of webercem five star repair concrete CP – which reaches 27N/mm² in 24 hours – was especially valuable in the tidal conditions in Fife. Tight shuttering was used on the wide beam sections of the jetty to take the poured concrete which reached an integral bond with the original concrete. This process reformed the structural integrity using products with proven durability.An innovative CP system using Duogard® hybrid anodes from CPT was installed to protect the steel reinforcement with the anodes fixed into the soffits with a special CPT mortar. Where the CP installation required chases to carry the cabling, webercem HB40 high-build structural repair mortar was used to fill and seal the chases. webercem bondcoat, a polymer-modified, cementitious bonding aid and steel reinforcement primer, was first applied into the chases to ensure enhanced bonding. webercem HB40 is an acrylic-polymer modified, single component mortar and is lightweight with high build qualities. It can be applied in layers up to 75mm thick vertically, and 50mm on overhead soffits, and can be used without formwork. It was then applied onto the tacky webercem bondcoat primer and finished flush to the concrete surface.The Braefoot Bay terminal project has been completed successfully and Dewi Miller, contracts manager, BBCS, is confident that the jetty protection will extend the working life of the structure. "The products we have used are excellent and the application methods have enabled us to deliver a high degree of protection and reinstatement to the concrete structure. Working on a live site in a tidal zone has required a flexible work schedule but the whole project has worked exactly to plan and the client is very pleased with the result. The Weber materials have been the key to achieving this success."

You’ve likely seen the work of Charlie Davis amongst the pages of your favourite home renovation magazines. A Sussex-based Freelance Stylist specialising in interiors, Charlie has more recently turned her attention to the renovation of a double-fronted Victorian property. This outstanding example of 19th Century architecture will become a Location House, which with Charlie’s creative vision will be available for hire for photo shoots, tv, film and events.The spare room of the house was to become the perfect photography backdrop, reminiscent of perfectly imperfect Venetian plaster. The walls and cornicing would be decorated to replicate a historic limewash finish, a trend we continue to see grow in popularity.Charlie spoke with Amie Paxton, Technical Sales Advisor for KEIM Mineral Paints, on how to create the perfect finish. With just a handful of inspiration photographs, Amie produced a selection of sample boards combining award-winning KEIM Innostar with KEIM Restauro Lasur, a colourwash similar in appearance to limewash and just as breathable but composed of mineral pigments and potassium silicate for a permanent chemical bond.Charlie opted for KEIM Innostar 9314 with KEIM Restauro Lasur 9529 for the walls and KEIM Innostar 9255 with KEIM Restauro Lasur 9249 for the decorative cornice, commenting on receipt of the mock ups; “the samples look absolutely gorgeous, they are just what we wanted.”Armed with KEIM’s Oval Brush and with minimum application guidance, Charlie created an authentic looking and elegant limewash finish throughout the spare room of her Location House, available to hire via 07.crescent_locationhouse on Instagram.The process of creating a limewash finish onto any interior mineral substrate, whether previously painted or bare, is much easier than you may think and can be as simple as just two coats of paint. If you’re inspired to create your own serene space or would like further information, contact Amie Paxton via sales@keimpaints.co.ukCharlie commented “we have finally finished the room with your products and it looks incredible! I have already had people ask about it and I have referred them to you. It is exactly what I was hoping for and looks so incredibly stylish! Thank you.”The exterior of the property was also decorated using KEIM Paints. KEIM Fixativ was applied onto the lime render, followed by KEIM Soldalit Grob to equalise textural differences from the lime patch repairs. KEIM Soldalit-ME 9197 and AG71 was chosen for this Victorian property, including the porch and mouldings.  

Junckers solid hardwood flooring has been installed in two galleries at The Science Museum; Technicians: The David Sainsbury Gallery, and the Engineers Gallery. Copenhagen -based design consultancy JAC Studios specified Junckers Oak Boulevard Harmony, a generously proportioned wide board plank floor, introducing a natural element to the large spaces. Technicians: The David Sainsbury Gallery is a free, interactive gallery for 11–16-year-olds which highlights the crucial but often unseen role of technicians, aiming to change perceptions of technical careers and inspire tomorrow’s technicians. Visitors can go behind the scenes and explore 100 different technician roles, among them advanced manufacturing, creative industries, health science and renewable energy. The museum has collaborated with Marvel Studios, the NHS, the National Grid, the University of Sheffield Advanced Manufacturing Research Centre (AMRC) and many other organisations to bring the essential role of technicians to life in the gallery. There are five inter-connected areas, designed as a three -dimensional grid-like structure. Founder and artistic director of JAC Studios Johan Carlsson stated sustainability as a huge factor in the design, with the team opting to only use responsibly sourced wood. With FSC® and PEFCTM chain of custody certification as well as EPDs, Junckers wooden floors fit the bill perfectly, fulfilling the strict criteria. Even though the gallery is intended to be a permanent fixture at the museum, the principles of disassembly were applied at the design stage to encourage reuse of materials and make future updates to the gallery easier. The Oak Boulevard flooring can be lifted without damaging the boards and reused or repurposed in a different location. Junckers flooring has also been installed in The Engineers Gallery where visitors can explore iconic objects such as the first digital camera, a surgical robot arm, an atomic clock that formed the basis for the entire GPS system as well as learn about the remarkable people who invented them. The gallery is divided into four distinct areas, all fitted with Oak Boulevard Harmony. Made in solid hardwood, Oak Boulevard is a durable and long-lasting flooring solution for the museum. It can be sanded and refinished up to ten times and with regular maintenance a design life of 60+ years is easily achieved. Designed for high-traffic areas, the floor provides a hard -wearing surface which is completely smooth, ideal for areas where accessibility is paramount. In addition, all Junckers flooring carry the Danish Indoor Climate label, ensuring specifiers and users there are no harmful chemicals in the flooring that will have an adverse effect on air quality. 

Leading UK utility contractor, Telent, have used UltraCrete’s superb ironwork installation materials to repair and install a CW1 access cover in Sutton Coldfield.BackgroundAs part of their ongoing commitment to maintaining the UK’s national utility infrastructure, Telent have used UltraCrete’s latest product innovation Mortar Buoy® to repair a chamber and install a CW1 ironwork access cover in the West Midlands.The ChallengeLocated on a busy junction, it was crucial that the repair and installation of the CW1 cover was carried out quickly to minimise disruption to motorists. With a reputation drawing on decades of experience in the design, build, support and management of the UK’s critical infrastructure, it was imperative that Telent used reputable installation materials that had been tried, tested and proven to work in the road network.The SolutionUltraCrete’s independently tested and approved ironwork installation system was specified by BT Openreach to complete the project.The new CW1 cover was installed using the Install Plus method. To begin, Mortar Buoy® was inflated in the existing chamber to prevent debris falling into the cavity and causing potential damage to the network. Once inflated, the team were able to use Mortar Buoy® as internal shuttering and repair the damaged chamber using QC10 F rapid strength flowable concrete.QC10 F, part of UltraCrete’s range of high specification concretes, is rapid setting fibre modified concrete for backfilling around manhole frames and gullies and for surface repairs.To complete the installation, Mortar Buoy® was used as a dam and Envirobed® CD534 Flowable was poured around the edges of a chamber for a permanent installation.Specially formulated for utility reinstatements, Envirobed® CD534 Flowable high performance bedding mortar is BT LN550 and LN320 compliant and offers superior compressive, tensile and flexural strengths in just 3 hours.Mortar Buoy® is a ground-breaking, innovative, inflatable access frame that acts as a dam, allowing for a flowable mortar ironwork installation in seconds – revolutionising traditional methods.Enhance your specification and upgrade your reinstatement with UltraCrete Mortar Buoy®.ResultsThe project took place on a mild winter day in December 2021. The work was completed without delay and with minimal disruption. Using Mortar Buoy® instead of a traditional damming mortar increased the speed of the installation, reduced costs and made the install less labour intensive for the team.On the performance of Mortar Buoy®, John Doherty, Area Supervisor for Telent commented: “Mortar Buoy® makes life much easier versus traditional shuttering for both chamber repair and bedding the ironwork. It is also much faster.”

The redevelopment of Gainsborough’s House in Suffolk required specialist acoustic design to isolate the structure from the vibrations of a nearby silk mill. Regupol Vibration offered a practical solution, but the project was not without its challenges, including a tight site and lockdown restrictions.The ProjectGainsborough’s House is the childhood home of the renowned 18th Century artist Thomas Gainsborough. The house and gardens, which are Grade 1 listed, were purchased by the Gainsborough’s House Society and were first opened to the public in 1961, housing a permanent collection of his work.Ambitious plans for the redevelopment of the house will transform it into a national centre for art in Suffolk, showcasing the influence of Gainsborough over other famous British landscape artists he inspired such as John Constable and JMW Turner, and acting as catalyst for regeneration of the town of Sudbury.As part of this project a new three storey wing is under construction next door to Gainsborough’s House, on the site of a former Labour Exchange. The contemporary building with a staggered roofline has been designed by architects and exhibition designers ZMMA. Complementing the existing listed buildings, which are to be upgraded, the project will create the largest gallery in Suffolk housing the widest collection of Gainsborough’s art and the art of those he inspired. The entire project is valued at £9m and construction began in the Autumn of 2019.Acoustic ChallengesFacilities in the new building will include permanent and temporary galleries, a landscape studio with panoramic views over the rooftops of the town and a new café overlooking the 18th Century garden. Whilst contemporary in appearance the extension will incorporate local materials including bricks from the historic Bulmer brickworks just outside the town, and interiors featuring famous Sudbury Silk.Sudbury has been a major silk manufacturing centre for centuries and five companies still make silk textiles in the town. Vanner’s Silk Mill, directly to the North of the site, has been producing Sudbury Silk for 250 years. However, its proximity to the new gallery is a challenge.Vibration Isolation for Art Gallery FoundationsAcoustic specialists Sandy Brown identified that the silk factory workings are a source of vibration throughout the surrounding grounds and buildings, which has the potential to interfere with the peace and tranquility of the new building.To mitigate this risk, respected engineers Eckersley O’Callaghan worked on a series of foundation design incorporating vibration isolation materials, which isolate the new structure from the surrounding ground. The successful design specified the use of Regupol Vibration Solution products, a range of isolation products which can be used to provide a resilient layer within foundations to isolate a building from structure borne vibrations.CMS Danskin Acoustics are the sole UK distributor of Regupol products. Regupol and Regufoam Vibration product ranges provide a combined 20 different grades of isolation material which can be used in a wide load range between 0.002 N/mm² and 2.5 N/mm². This wide range provides the opportunity to design efficient isolation concepts for even the most challenging vibration scenarios.The new building has a complex foundation plan with multiple stepped foundations and ground beams, producing three different regions of pressure. Each area required a different combination of material thickness and density to provide the appropriate deflection and natural frequency required. CMS Danskin Acoustics worked with the design team to develop a bespoke acoustic insulation strategy for Gainsborough’s House that was both efficient and effective.Working under Covid LockdownConstruction commenced in late 2019 with the demolition of the existing labour exchange where the new galleries were to be built. Principal contractor Thomas Sinden was ready in the spring of 2020 for the installation of the vibration insulation materials by specialist groundworks contractor T Vaughan. The narrow historic streets of Sudbury prevented the use of cranes and all materials had to be delivered by smaller vehicles.Regupol products are manufactured from recycled aircraft tyres in Germany, and the timing of the project during the first Covid lockdown couldn’t have been worse. However, CMS Danskin Acoustics retain good stock quantities and delivery of the required 1400m2 of rolls and tiles was not delayed by the suspension of travel.The design of the vibration isolation scheme called for several layers of Regupol Vibration 300, 450 and 480 in varying thicknesses, which were laid and cut over the foundation according to the insulation strategy. Each layer has staggered joints and the entire scheme is then covered with a separation membrane prior to the pouring of the floor slab.The new galleries at Gainsborough’s House are expected to open to the public in the Spring of 2022, and enjoyment of the spaces will be unaffected by the centuries old industry continuing next door.Vibration Isolation ServicesVibration Isolation is a specialist skill.
