CMS DANSKIN ACOUSTICS recommended a bespoke combination of industrial acoustic materials to ensure noise at work compliance at ExxonMobil Oil Refinery. The ChallengeFawley Oil Refinery is the largest oil refinery in the UK. When ExxonMobil found that the noise output from two industrial fans at the refinery exceeded the levels specified by The Control of Noise at Work Regulations, it consulted CMS Danskin Acoustics for advice. To ensure the most cost effective and high performing materials were specified, CMS Danskin Acoustics evaluated the noise reduction required on-site. Evaluation of the acoustic data revealed that noise levels in excess of 118dB at 125Hz were being emitted by the fans. Based on these criteria, the technical team at CMS Danskin Acoustics recommended the use of a combination of specialist materials from its industrial acoustic range. The SolutionTo control the low frequency-biased sound, CMS Danskin Acoustics recommended and supplied the SuperLag Quietslab Laminate with Acoustic Barrier Type WB10 combination for the fan casings and associated ductwork. Creating a multi-layered, high performance system, two layers of SuperLag Quietslab Laminate, totalling 250mm thickness, with a core of 5mm Acoustic Barrier Type WB10, were bonded onto the fan casings and ductwork. A direct coupled lagging system, SuperLag Quietslab Laminate comprises long-stranded mineral fibres thermo-set with resins for the absorption of sound at the surface, as well as a high mass inner acoustic barrier core to reduce the transmission of sound through the material. Manufactured from a weight-enhanced, high-density material, Acoustic Barrier Type WB10 provides a flexible and cost effective treatment for chemical and refinery applications. In total, 1,000m2 of the SuperLag Quietslab Laminate/Acoustic Barrier Type WB10 materials were installed around the fans and ductwork to achieve the high levels of sound reduction required.ResultsThe high performance bespoke system specified by CMS Danskin Acoustics, significantly reduced the noise generated by the fans. This enabled ExxonMobil to comply with The Control of Noise at Work Regulations by bringing noise levels under the 85dB compliance level.

The Post Building development completely remodels the former Royal Mail Sorting Office located on New Oxford Street in Central London into modern Grade A offices, with street level retail and restaurant space along with rooftop gardens, terraces, and leisure areas. The project received a prestigious RIBA London Award in 2022 and the main roof terrace is open to the public, providing panoramic views over the city. In order to gain planning approval, the development had to be repurposed in line with the ‘SuDS manual’ best practice guidance to minimise surface water run-off in the event of a storm and in order to meet the maximum discharge consent limits set by Thames Water.Basement SuDS storage is expensive and often impractical to achieve in city centre locations. ABG’s blueroof system was therefore chosen as an easy to install alternative to provide stormwater attenuation at roof level. The system is installed across three main roof areas and includes 14 restrictor chambers positioned above rainwater outlets to limit the outflow rate. The system is calculated to control stormwater in the event of a 1 in 100 year storm, based on the local Flood Studies Report (FSR) rainfall data, plus 30% allowance for climatic change.The roof design incorporates a variety of surface finishes, including a resin bound play area, biodiverse green roof areas and paved & decked terraced areas. The roof also includes solar PV arrays and planters supported on top of the blue roof.The ABG blueroof system drains like a normal roof during everyday rainfall events, but throughout the critical design storm periods restricts stormwater run-off, continuously releasing rainwater at a controlled rate until empty.The discharge rate is site specific and forms part of the scheme wide SuDS plan, and means that other downstream measures are not required. The scheme also included sedum green roofs to improve site biodiversity across two further areas.ABG provided project design calculations and all blue roof materials required for the different roof levels, plus our installation service.

Canberra HouseBauder Cold Applied LiquiTOP SystemSynopsisCanberra House is an office facility in Swindon. The existing single ply PVC waterproofing system roof was leaking and so Bauder carried out a full site survey. The resultant report gave the client several options to rectify the leaking roof.Bauder Building BoardProject nameCanberra HouseLocationSwindonProject typeRefurbishmentRoof size985m²SpecifierRapleys LLP (Bristol)Approved contractorCentral Roofing & Building Services LimitedThe specificationThe LiquiTOP system was chosen as it can be applied directly to the prepared and primed existing single ply covering. The liquid system allowed us to get into tight spaces and without the need for any hot works.LiquiTOP is excellent on refurbishment projects where the complexity of the roof involves intricate areas to be detailed that are not easily achieved with a sheet membrane, or the actual working space on the roof is constricted.Project challengesLarge areas of plant and machinery were situated just above the roof level making access to the areas below difficult with the plant in-situ. The available budget on this project did not allow for lifting or removing the plant, stripping the existing waterproofing system, and replacing with new. Therefore, the decision was made to overlay the existing single ply membrane with a cold applied liquid waterproofing which can be installed without the need to raise any plant.To overcome drainage challenges, secondary upstands were created under the plant and fabricated channels placed underneath allowing water to flow through to the drainage points.The resultBauder was able to offer a cost-effective solution without the necessity to remove or decommission the roof mounted plant and machinery. Cost reductions were achieved for the client by overlaying the existing roof, negating any need to strip existing materials, and not having to remove or raise the plant.The works were carried out by Central Roofing who manged the project impeccably and also finished ahead of schedule.System installedBauder Cold Applied LiquiTOP System1 LiquiTOP PU cold applied liquidA moisture triggered curing polyurethane waterproofing resin; applied in 2 coats, reinforced with Bauder LiquiTOP Glass Fibre Mat.

Flooring specialists Laceys Floors and Walls have used UltraFloor Level IT Hydra Bond to install 170sqm of flooring at Rushcliffe Country Park.BackgroundGreen Flag award winners since 2007, Rushcliffe Country Park is a popular visitor attraction in Nottinghamshire. Work is currently underway to renovate the visitor centre including staff office and toilets.The ChallengeExpert flooring specialists, Laceys Floors and Walls were the contractors commissioned to install 170sqm of flooring throughout the visitor centre. To complete the installation, Laceys Floors and Walls needed subfloor materials that would provide a super smooth finish to avoid any trip hazards and would withstand constant trafficking of visitors.The SolutionTo begin, Laceys Floors and Walls applied DPM IT damp proof membrane across the entire 170sqm area. DPM IT is a two component, solvent free epoxy resin system for use as a surface damp proof membrane. Designed to provide protection against subfloor moisture, DPM IT has a pot life of 45 – 75 minutes, a cure time of 5 hours and boasts a 98% RH floor moisture tolerance.Once fully cured, the team applied UltraFloor’s latest product innovation, Level IT Hydra Bond to a depth of 3-5mm.Level IT Hydra Bond is a super polymer modified smoothing compound which utilises UltraFloor’s unique technology – a process which enhances application and boasts unrivalled flow properties. What’s more, each bag of Level IT Hydra Bond also contains 20% recycled material.In addition, Level IT Hydra Bond can receive bonded floor coverings after 4 hours, has an extended working time of 45 minutes for optimal usability, and is moisture tolerant and protein free.To complete the project, Polysafe Wood FX and Verona flooring was installed throughout the visitor centre, office and toilets.ResultsThe flooring was installed with ease and Rushcliffe County Park’s exciting new visitor centre is due to open later this year.“Level IT Hydra Bond was a real pleasure to work with. It was easy to trowel and float on the floor and knitted together great between mixes. It even went nicely on the previous days screeding.” Richard Lacey, Director at Laceys Floors and Walls.

The Protec System was used to waterproof the domed green roof areas of this striking, sustainable house development which was featured on Chanel 4’s Grand Designs. With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming a dated 1980’s house overlooking Lake Windermere into a state-of-the-art, eco-conscious home. Since the house lay in beautiful hillside surroundings, in order to blend into this setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction.The SolutionThe Protec System was chosen as a waterproofing membrane for the roofs as it is ideally suited for green roof applications. Lightweight, flexible and highly durable, the system can easily accommodate structural expansion movements and is tough enough to resist root penetration. The Protec system was applied to over 350m2 of domed roof to provide a long-lasting waterproofing membrane.The key reasons why Eastleigh chose Protec are the same reasons that has seen it become one of the fastest growing cold-applied liquid roofing systems in both the new build and refurbishment markets. Combined with the timber cladding to the verticals of the building, the finished aesthetics of the development blended seamlessly with the surrounding areas.A warm roof build-up that can be made waterproof at multiple stages:For larger projects the Protec system can be made temporarily waterproof at two stages prior to the application of the full waterproofing system. The first stage is upon installation of the sealed, aluminium-faced vapour barrier.The second phase follows the reinforcing of the foil-faced insulation board joints with Protec resin and taping mat. This enables a much more controlled approach to the installation with a greatly reduced chance of rain causing disruption and damage during the works.Highly flexible membrane:Regardless of the size of the roof, Protec forms a homegenous membrane, without a single joint or seam and without the need for any expansion joints.RapidCure technology for quick installation:The application of Protec as a liquid, through to the curing process where a solid, tough membrane that can be walked over, takes only 30 – 60 minutes. This enables large sections of the roof to be fully completed in a short space of time.Installing the Roofing SystemsThe Protec System provided waterproofing to all flat roof areas as well as the extensive parapet wall sections. The roof areas were made up of two designs: the Protec Warm Roof System (approx 7,500m2) and Protec applied to concrete as part of an inverted roof design (approx 1,000m2).The roof installation was carried out with a planned, phased approach that was synchronised to the wider construction schedule. For the warm roof areas, the first stage was to fill the troughs of the structural metal roof deck with acoustic insulation infills that will dampen external noise within the leisure centre. Next, the crowns of the deck were primed ready to receive the self-adhesive vapour barrier.The use of a high-performance aluminium vapour barrier not only eliminates the risk of condensation within the roof, but also provides temporary waterproofing protection, which is extremely useful on larger works such as this.The Polyroof RES Insulation boards, which comprised of a two layer system totalling 170mm to achieve a U-Value of 0.14 W/m2K, were bonded using high-performance PU adhesive to the vapour barrier. Following the wind uplift calculations it was determined that mechanical fixings were not required for this application – making for an extremely rapid installation. As you can probably imagine, fixing through 170mm of insulation into the crowns of the metal deck can be a tricky and time-consuming task.A key advantage of using a tongue and groove insulation system is that the finished surface of the roof is smooth and level without any unsightly board steps that can also lead to standing water issues. The insulation board joints were sealed using Protec resin with Polymat Taping Mat 450 which, in addition to providing additional strength to the joints, also creates a temporarily waterproof layer.For the inverted roof sections, Protec was applied directly to the primed concrete/screed surface. The membrane was inspected by Polyroof Technical Services, signed off and then covered with inverted roof components. An interesting fact when using Protec in inverted roof situations is its incredible durability performance – as tested by the BBA, Protec “can provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated”.Monitoring and CompletionThroughout the duration of the contract, Polyroof Technical Services carried out regular site visits that were reported back to Interserve as part of Polyroof’s free-of-charge contract monitoring service. This enabled the client to keep up-to-date with the progress of the roof installation in detail and also provided peace of mind that the original specification was being closely followed and implemented.Polyroof worked closely with the Roofline Group during the installation, enabling the challenges were identified and solved in an efficient and coordinated manner – saving the client time and money.

The Quartermile development is a cosmopolitan mix of luxury apartments, cafes and businesses in the heart of Edinburgh city centre. The masterplan for the new area is designed by Foster + Partners and enjoys views of some of Edinburgh’s greatest landmarks. The access to the new building (adjacent to the old Edinburgh Royal Infirmary site) is elevated from the North Meadow Walk pedestrian walkway and cycle route. The pathways and landscaped areas in front of the development needed a structural drainage solution and reinforced turf area that would be suitable for trafficking by maintenance and emergency vehicles when required.ABG’s high strength Roofdrain 60S+RX geocomposite was specified to provide sub-surface drainage across the base of the podium deck. The drainage board provides a high flow capacity void to channel water pressure to the surrounding perimeter drains. By utilising a 60mm drainage layer the need for much deeper and harder to install drainage stone layers can be minimised. The carbon footprint for the product is just 3.3 kgCO2e per m2 which is an approximate 50% saving compared to the embodied carbon of quarrying, transportation and installation of the equivalent thickness of drainage aggregates. Once installed the Roofdrain core is filled with pea gravel to provide a rigid sub-base beneath a bedding layer and resin bound gravel pathways. The drainage core features regular perforations to allow surface water to percolate and drain to the underside of the board. Adjoining rolls can be easily overlapped with the cups designed to slot  into one another. The Roofdrain was overlaid with a Terrex NW9 geotextile to prevent fines entering the drainage core. The Roofdrain can be stepped to cascade into lower sections to suit the landscaping layout. The main green area to the front of the building was cultivated using the Advanced Turf reinforced grass system. The Netlon Advanced Turf System (Netlon ATS) is a high performance, mesh-element reinforced natural grass rootzone system that provides a SuDS compliant free-draining grassed surface. It consists of a high quality, sandy soil rootzone into which thousands of playing card sized polypropylene Netlon plastic mesh elements are pre-blended. The composite mesh reinforced rootzone and selected turf are then delivered to site as a system. ATS was specified for this development to support loading by occasional MEWP vehicles such as cherry pickers, and in the event emergency vehicles need to traffic onto the grass.

Artform Urban provides colourful external furniture elements to a new state-of-the-art Children and Young Peoples' Mental Health Service (CYPMHS) inpatient unit for West Yorkshire. Based at the St Mary’s Hospital site in Armley, Leeds, the five-year project led by Leeds and York Partnership NHS Foundation Trust opened in January 2022. The new facility comprises a 16-bed general adolescent ward and a 6-bed psychiatric intensive care unit all supported by an expert team to offer a range of therapies and support. The building wraps around central courtyards to provide dedicated access to garden spaces at all times. In total there are 4 separate outdoor spaces all have been furnished by Artform Urban Furniture. The primary products specified by Ares Landscape Architects are the Loop range of street furniture; including curving loop benches, conical picnic sets, and Hop Op 500 stools. The products are ideally suited to CAMHS units due to the minimal design and lack of any removable fixtures. The Loop range is formed of rotationally moulded Polyurethane which creates a soft and flexible surface with no sharp edges - this was a key factor in why these products were chosen. The Loop range is also lightweight and can be easily positioned and secured in place using hidden fixtures or alternatively filled with sand or water to be self-weighted units that can be moved as and when required.A bespoke element has been introduced with circular sheets of HPL (High-Pressure Laminate) being added as table toppers to achieve a tamper-proof finish. HPL is manufactured by combining sheets of recycled paper with a binding resin under high pressure - achieving a robust weather-resistant material ideal for external environments.The playful design and inviting colours create a positive and calming atmosphere encouraging time to be spent outside in the fresh air. In the larger garden space, several Stone benches have been installed - in various finishes. The pebble-like design sits naturally in the leafy garden and creates an impromptu social space.In order to facilitate client timings, Artform provided an installation service as well as advice/ guidance during out-of-usual operational hours between Christmas and New Year.For the final installations - Full coordination with the management team was required at Red Kite View as it was now a live site. It was imperative there was no interruption to the patient’s routines while the products were moved through the building and installed.The building was designed in collaboration with clinicians and young people who all contributed their ideas, hopes, and aspirations for care. They also helped to decide on the name ‘Red Kite View’ as nature is strongly associated with mental wellbeing and rehabilitation.

450 sash windows restored and double glazing installed by ventrolla at royal academyKEY FEATURES: COMMERCIAL, GRADE II LISTED, SASH WINDOWS, EDUCATION, RENOVATION, DOUBLE GLAZING, VENTROLLA PERIMETER SEALING SYSTEM, VICTORIAN.After the existing windows, dating back to 1862, were given their marching orders due to their poor condition, the timber renovation specialists were drafted in to upgrade the ageing sashes.As part of a £7.5 million refurbishment across two years, the Grade II listed building, used by the Army Medical Directorate, presented 450 sash windows in dire need of  complete renovation and upgrade due to many years of exposure to the elements.The majority of sashes were one and a half metres tall with larger ground floor windows reaching two and half metres.The deteriorated condition of both the sashes and frames meant the building was very draughty with many of the windows being rotten and inoperable.To remedy these problems the rotten timber was routed out of the original box frames, and replaced with Ventrolla’s patented epoxy resin VR90. Preserving the original sash windows was just as important as improving the energy efficiency of the building.Following this process, the unique Ventrolla Perimeter Sealing System (VPSS) was installed to combat draughts and reduce external noise. The sash cords were then replaced, pulleys serviced and sashes correctly balanced to ensure the smooth and safe operation of the windows. Andy Meachen, Project Manager of the Military Academy, said:“The service that Ventrolla provided was excellent and we were very pleased with the final result. We have really benefited from the renovation work as the building is noticeably warmer, there are no more draughts and the windows now open easily.”“We were very concerned about maintaining the aesthetics of the building and being sympathetic to its heritage, Ventrolla managed this beautifully.”“Due to their professionalism and craftsmanship, we have also asked them to start work on our Old College renovation project too.”The Royal Military Academy, Sandhurst was founded in 1947 and offers military, practical and academic training.With over 30 years experience, Ventrolla offers a tailored range of period window solutions. Their unique service includes draught-proofing with the Ventrolla Perimeter Sealing System (VPSS) and fitting replacement double-glazed sashes that incorporate the patented Sash Removal System (SRS) for easy painting and future maintenance.They also offer complete new timber windows, secondary glazing solutions and a wide range of window hardware. Ventrolla has its head office in Harrogate, North Yorkshire and regional offices located throughout the UK and Ireland.

CRT Flooring Specialists Ltd have used UltraFloor’s latest product innovation, Level IT Hydra Bond, to install 800sqm of vinyl flooring at Warrington’s £4.3 million Emergency Department extension.BackgroundLeading infrastructure and building specialists, Tilbury Douglas, have been appointed by Warrington and Halton Teaching Hospitals NHS Trust to complete the £4.3 million Warrington Emergency Department extension.The much-needed investment will increase capacity, improve patient care and modernise facilities.The ChallengeHigh performance products that would work quickly and withstand the constant and heavy trafficking of hospital staff, patients and medical equipment were critical to the success of this project.The SolutionFollowing a bespoke site specification completed by UltraFloor’s Technical Training and Site Support Manager, Martin Pouncey, CFA members and expert flooring contractors, CRT Flooring Specialists Ltd, used DPM IT, Prime IT Multi-surface Primer and Level IT Hydra Bond to complete the 800sqm installation.DPM IT is a two component, solvent free epoxy resin system for use as a surface damp proof membrane.

Located at the first locks of the Manchester, Bolton & Bury Canal, the second phase of the £1bn Middlewood Locks development in Salford delivers 546 apartments across 4 new buildings with private podium gardens. Phase 2 of the development is part of the wider mixed-use scheme to regenerate 25 hectares of brownfield land with new apartments, office space, a hotel, bars, restaurants, car parking and a gym.The large catchment area of the development discharges to the newly renovated balancing basins that service the confluence of adjacent canals and the River Irwell. An extensive podium drainage landscaping design was required to meet the site’s strict discharge limits and reduce the impact of surface water run-off to less than that of the pre-developed brownfield land.The ABG blueroof storm water attenuation system specified for the scheme covers over 9,500 m2 and restricts rainfall outflows to below the 16 l/s discharge limit on Plot G of the site and within the 20 l/s limit for Plot H. The system incorporates 27 ABG restrictor chambers above rainwater outlets which are configured to restrict outflow rates to within the discharge consents.The system is designed to attenuate a 1-in-100 storm event (data extrapolated from the local FEH 2013 flood report), plus 30% allowance for the effects of climate change. The geocomposite drainage and attenuation layers and network of restrictor chambers serve to filter surface water run-off pollutants to treatment train stage one of the SuDS process, meaning no other filtration measures are required. The top of the chambers are designed to sit flush with the porous resin paving surface, and different configurations and thicknesses of drainage composites were used to achieve the correct height of system to match the different surface levels. The ABG Deckdrain geocomposite layer provides multi-directional flow capacity to efficiently channel rainwater to the nearest restrictor chamber outlet whilst the integral geotextile filter helps to prevent the cuspated drainage core from becoming blocked.The choice of hard and soft landscaping materials specified for the development are of a very high standard and the inclusion of large areas of green spaces and substantial planting creates valuable new private gardens and amenity spaces for the area.The attenuation system configuration was designed and supplied by ABG and installed over a 6 month period by ABG Installs. As part of the storm water attenuation system design, a new restrictor chamber diffuser was developed to fit directly onto the downpipes of the apartment buildings. The attenuation voids were modified to allow for cable ducting to pass through them and a method was also developed to provide structural drainage beneath the concrete footings of the stone planter walls.
