Ulticolour, Tarmac's coloured asphalt was used to surface the redeveloped Promenade at Morecambe. The buff colour complemented the clean, modern design of the new sea wall. It provided an accessible, trip-free surface with minimal maintenance requirement. The existing surface was an old hot rolled asphalt which was suffering from cracking. To resist cracking in the new surface and extend pavement life, ULTIMAT SAMI, Tarmac’s innovative stress absorbing membrane interlayer was also used. For more details visit the Tarmac website.

The client, a rugby club in Leicestershire, had recently upgraded their facilities to include new function rooms. They were now planning to improve their 4500m2 car park to replace the existing loose planings with a safe, permanent all weather surface. Using Ultifastpave reduced the construction time by half compared to conventional surfacing, generating a significant cost saving for the client. For more details visit the Tarmac website.

This high profile entertainment and tourist venue in Bishop Auckland, required a surface for the large pedestrian area next to its main arena. Ulticolour was chosen in a buff colour, which suited the visual theme of the site. The client was happy with the speed of the work and the smooth, even low maintenance finish.

Conserving a Grade I listed building with renovating plaster.Halifax’s Grade I listed Piece Hall is a true monument to the town’s industrial heritage. As part of Calderdale Council’s ambitious plans to conserve the building and transform it into a cultural and commercial hub for Halifax, a series of delicate remedial works were outlined to future-proof the structure’s original features and ensure it would be able to live up to the rigours of 21st century life. Under the schedule of works, Tarmac’s Limelite renovating plaster was chosen to provide a durable solution which was both sympathetic to the age of the building, yet robust enough to provide long-lasting results.The ChallengeFirst constructed in 1779, the Grade I listed Piece Hall takes its name from its original use as a cloth hall, where local weavers were allowed to sell their ‘pieces’ at the height of the industrial revolution. As an iconic reminder of Halifax’s prominence in the Georgian wool trade, the site is understandably a treasured landmark for local people.The aim of the Piece Hall transformation project was to conserve the historic fabric of the building and create an outstanding heritage destination fit for the 21st century. This would see the property, which consists of 315 rooms centred around a 66,000 sqft piazza, return to its previous grandeur and be reinvented as a new cultural and commercial centre for the town.The Piece Hall transformation project was delivered by Calderdale Council and made possible by funding from the Council, a generous £7 million grant from the Heritage Lottery Fund – thanks to National Lottery players – and kind support from both the Garfield Weston Foundation and the Wolfson Foundation. The Piece Hall is now operated by an independent body, the newly formed charity The Piece Hall Trust.It was vital that a specialist heritage renovating plaster was specified, to ensure that any remedial work undertaken would be in keeping with the property’s original features and sympathetic to the materials used during the building’s original construction in 1779.The plastering contractors chosen to undertake the work, Manchester Screeding Contractors (MSC), were challenged with plastering the inside of the iconic arches which surround The Piece Hall’s piazza, as well as re-plastering walls within a number of rooms on the ground floor. Given the need to use a specialist heritage plaster, MSC turned to Tarmac’s Limelite team for help.For the interior work, damaged and ageing plaster had to be removed, revealing solid stone walls which needed to be plastered in keeping with the heritage of the building. Time and weather had also eroded the exterior arches, and an appropriate solution needed to be found.Installation time was also a challenge on the project as the construction phase was nearing hand-over to The Piece Hall Trust, with the building due to be reopened to the public in August 2017.The SolutionTo satisfy the specification, MSC first chose to use Tarmac’s Limelite Easy Bond as a primer, given its ability to effectively control suction and salts, as well as improve the level of adhesion when working with difficult substrates. Following this, two coats of Limelite Renovating Plaster were applied as a backing plaster to the surfaces to remove undulation.Tom Emery, Specifications Co-ordinator at Tarmac’s Limelite division, comments: “A traditional lime plaster could take months to dry out whereas renovating plaster only takes 24 hours to dry per coat. This was essential in helping the team to cope with the tight timescales of the project.“Moisture, damp and mould growth were also found in the building. Renovating plaster is ideal in scenarios like this, as the level of breathability it offers will allow moisture to easily pass through it. It is this breathability that will significantly reduce the likelihood of damp occurring.Tom continues, “The renovating plaster was followed with a final coat of Limelite’s High Impact Finishing Plaster. The High Impact Finishing plaster is extremely durable, which is ideal given the municipal use of the building. What’s more, it’s great for use in heavily trafficked areas as it provides a shell to the backing plaster.”In total, seven tonnes of product were supplied to the project in the two-month timeframe, with MSC working through the weekends to get the job done.Karl Hodgkiss, Managing Director of Manchester Screeding Contractors, commented: “Internal and external plastering as well as restoration plastering are key specialist areas for our business, and this was a significant project for us that we were excited to be a part of. I had used Limelite’s renovating plaster before in smaller quantities and knew it would provide a breathable covering for the original stonework.”

THE CHALLENGE Milner Hall, a former chapel in Winchester, is one of the oldest structures in the city and a building of great architectural and religious importance. Built by the Reverend John Milner in 1792, the hall is now used for community events and meetings. In addition to the significant heritage of Milner Hall, an X-ray of the western elevation found a number of voids in the foundation due to hundreds of years of water damage. What’s more, part of an inadequate retaining wall had collapsed onto the same elevation, with the potential to cause further damage if left untreated. When Tarmac’s Limelite team was approached regarding the Milner Hall project, they instantly recommended Tempo PCE who they’d successfully worked with a number of times. THE SOLUTION Tempo PCE commonly chooses Limelite 7 for its projects; a Tarmac grout with hydraulic lime content that’s specially designed for heritage buildings, especially ancient structures such as churches. This was the ideal product to suit the needs of Milner Hall where the grout would need to be injected at a low pressure from the outside, directly filling the internal voids. Tom Phillips, Director of Tempo PCE, said: “We regularly use Limelite products and Limelite 7 was ideal for the work required at Milner Hall. The technical support they offer is incredibly valuable, as well as their reach and industry-reputation. “We strive to only work with manufacturers who can offer value and work with us as partners to ensure the best possible product is provided for a strong finish. We certainly get that with Tarmac’s Limelite team.” Iain Spence, Technical Manager for Tarmac’s Limelite range, added: “Historic structures often present suppliers with a wide number of challenges when it comes to the specification of suitable materials, and their subsequent installation. “In the case of the work at Milner Hall, the requirement was for a fluid, low strength grout that would stabilise the void in the masonry of this Grade II listed building. The Limelite Heritage Grout system provided a breathable low-density solution for these works. “Given the often delicate nature of period and historical structural repair projects, working with dedicated and knowledgeable contractors is essential to achieving the correct end result. Tempo PCE completed the works at Milner Hall utilising their extensive application skills with the Limelite Grout, delivering a much-needed structural support to the building’s foundations which should add many more years to its operational life.” 

St Pancras StationProject briefLimelite Heritage Mortars and Grouts to help restore St Pancras station buildings to their Victorian splendour.The ProjectMortars and Grouts from Tarmac Building Products, the leading manufacturer of blended cementitious products in the UK, have been extensively used in the historic conservation of St Pancras station.The major redevelopment of St Pancras includes the enlargement and refurbishment of the ticket hall, restoration of St Pancras Chambers as well as new passages to the existing Tube ticket Hall and Channel Tunnel Rail Link. PAYE Stonework and Restoration, a leading conservation specialist turned to Pozament for its expertise in pre-blended products formulated specifically for historic conservation work.A hydraulic lime-based combination of materials that offers sympathetic controlled strength was blended by the team to meet the specific requirements of PAYE Stonework and Restoration.Help from Tarmac Building Products – Limelite Heritage Mortars & GroutsAround eight tonnes of lime based, cement-free materials including Heritage Mortar 4 and Heritage Grout 7 were supplied to point the brickwork joints of passages to the existing tube ticket hall and Channel Tunnel Rail Link and to repair sofits in the Grade I listed St Pancras Chambers.Problems facedSt. Pancras Station is a Grade I listed building, meaning it is a building of exceptional interest and is one of the best Victorian buildings in central London. It has been voted one of London’s favourite landmarks and so great care had to be taken with the restoration work.OutcomesThe extensive redevelopment of St Pancras and Kings Cross Underground was completed by the end of 2007.  QuotesGary Hodges, project manager, PAYE Stonework and Restoration said, the range of pre-blended heritage grouts and mortars were ideal for this restoration project. Heritage Mortar 4 was highly suitable for the St Pancras Chambers repairs, reaching maximum strength within 7 days rather than the usual 90 days for other materials.Stuart Allerton, Quality & Technical Services Manager, Tarmac Building Products said, The Limelite Heritage range has specifically been designed to be sympathetic with historic buildings and caters for a number of applications. Our re-pointing mortars and free-flowing grouts are manufactured at our Swadlincote facility in Derbyshire to order, typically within five working days.·      Location: London·      Product: Limelite Heritage Mortars and Grouts·      Timescale: Completed in 2007

Project brief:A monumental restoration project for the iconic St Paul’s Cathedral spanning 15 years and costing £40 million. It was the first comprehensive restoration project that the Cathedral has gone through and this extensive cleaning, repair and renovation programme was one of the largest of its kind ever in the UK.The Project:It doesn’t get much more high profile than this when it comes to historic building restoration. As part of the London skyline for over 300 years, the requirement was for materials that perfectly balanced the strength and performance to do the job with the delicate nature of working with such a fragile and weathered structure. The sheer scale of the project also dictated the need for an extremely consistent product.Help from Tarmac Building Products – St. Pauls Grout Mix:Pozament, from Tarmac Building Products Ltd, boasts the heritage range of Limelite Grouts and Mortars specifically designed for such tasks. Yet in a project of such epic proportions and with the stakes so high our technicians instead produced an all new low strength blend of PFA, lime and special additives, that was capable of penetrating the fine voids and fissures in the Cathedral’s structure, whilst remaining sympathetic to the existing materials.The new grout, now named St. Paul’s Grout Mix, is easily mixed and in addition can be placed using gravity feed techniques, which are often used to ensure low pressures that are needed to avoid damage to delicate structures, such as in the case of St. Paul’s Cathedral.St. Paul’s Grout was designed to achieve a low strength of approximately 2.0 N/mm2 at 28 days, which was sufficient to strengthen and fill voids in the heartening of the masonry walls at St. Pauls Cathedral. The mix also contains a special plasticiser/wetting aid, so that when used at a water solids ratio of 0.4, a very fluid mix capable of penetrating fine voids and fissures is produced.Outcomes:The St. Paul’s Restoration project was finally finished in June 2011. To this day Tarmac continue to produce the St. Paul’s Grout when required and since then, it has been used successfully on many similar restoration projects including York City Wall, Winchester Cathedral and other English Heritage projects.

Project briefTarmac Building Products were asked to supply Queen Mary’s development (a historic London hospital converted into apartments) with Limelite Heritage Hydraulic Lime Mortars.The ProjectThe project ‘s aim is to convert Grade I Baroque stately home Roehampton House into residential use with a mix of old and modern construction materials. Roehampton House is a Grade I Baroque Stately Home built by Thomas Archer over the years 1710-12 and later enlarged by Sir Edwin Lutyens in 1910. The house is being carefully restored, maintaining its original features both internally and externally, with Doric columns and wrought iron railings giving way to panelled walls, ornate painted ceilings and black and white marble.Help from Tarmac Building Products – Limelite Heritage Lime MortarsWe supplied Limelite Heritage Hydraulic Lime Mortars in mobile dry silos to the large-scale heritage site in Roehampton, south-west London. The product is predominantly a bedding masonry mortar but due to its versatility, can be used in other areas and is ideal for projects such as this one because it is a cement-free traditional product and so recreates an appearance in keeping with the history of the building. It is being supplied alongside natural and Y101 white mortar in dry silos.Our Heritage Hydraulic Lime Mortar is ideal for projects such as this one because it is a cement-free traditional product and so recreates an appearance, maintaining the history of the building.Problems facedThe former hospital developed into a stately home is a Grade I listed building, meaning that any new building work needs to blend in well with the existing building work. Grade I buildings are of exceptional interest, sometimes considered to be internationally important; only 2.5% of listed buildings are Grade I.The project site is located within Flood Zone 1 and so a Flood Risk Assessment is required as the site is over 1 hectare. OutcomesRoehampton House, its two gate houses and the remainder of the Roehampton Estate are being redeveloped to provide luxury new housing. The development is called Queen Mary’s Place. Of the original 30 acres, only 14 remained following the building of the new hospital, but the developer, St. James has preserved 30% of the land for pleasure gardens for the new residents.The Grade II listed sunken and rose gardens have also been lovingly restored to provide the perfect setting for the newly created 1, 2 and 3 bedroom apartments and two 2 bedroom gate houses.·      Contractor: St James Development·      Location: Roehampton, London ·  Product: Limelite Heritage Lime Mortar

This leading residential housing developer, required a new surface for the car park at its headquarters. It was a large site, with around 200 parking spaces for staff and visitors. The new surface would need to withstand the impact of regular vehicle movement and the abrasion caused by power assisted turning. The surface would also be used by larger vehicles making deliveries. Tarmac’s ULTIDRIVE asphalt was chosen as the solution. Designed to resist the long term effects of daily vehicle movement, ULTIDRIVE is a high performance asphalt with a smooth and highly durable finish. An advanced modified binder provides improved resistance to scuffing and abrasion from power-assisted turning. It also reduces softening in hot weather. ULTIDRIVE also provides enhanced resistance to temporary fuel and oil spills compared to conventional asphalt.

The Glass Yard is a prestigious mixed office and retail development in Chesterfield, on the site of what was the once the largest manufacturer of domestic glassware in the UK. It has been designed sustainably and ergonomically by developer Blue Deer Ltd. for an open plan, daylight filled environment. The client approached Tarmac’s representatives looking for a safe, practical, durable and visually distinctive finish for the main external walkways and first-floor balconies that would complement the modern design and sustainable ethos of the building. After providing advice and number of samples, the client chose TOPTINT Glow a unique, glow in the dark decorative concrete that uses light sensitive chippings to help illuminate areas such as footpaths, cycleways and pedestrian areas. The glowing aggregate provided a passive and energy efficient form of demarcation to help guide clients along the balconies and walkways at night-time and in low ambient light conditions. This fitted with the building’s sustainable design ethos. The gentle glow provided by the light emitting chippings also provided an ambience that was sure to be a talking point for customers and would help put the new development on the map.

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. 

Dawnus Civil Engineering were commissioned by Cardiff CC to construct a hydro electric power station at Radyr Weir. The £2.6m scheme comprised of damming the section of works from the River Taff and constructing the structure to house the Archimedes turbine screws. They required a concrete that could take the weight of the screws 3 days after pouring and asked for a 3 day strength of 50N.Tarmac suggested TOPROC ED which is a high performance readymixed concrete suitable for use in industrial, commercial and infrastructure construction where high early strength is required.

A complete rework of a postmodern office building (60 London Wall), situated in the heart of the City of London. The project aim was to extensively refurbish, reconfigure, reinvent and reposition the building.Due to the addition of a composite metal deck floor extension and additional steel frame for the top floors, Tarmac’s Toplight C lightweight structural concrete was seen as the perfect solution as it could be pumped and ensured a weight loss of 30% whiel maintaining the necessary structural performance.

This major expansion of the deep-water container terminal at Liverpool docks would significantly increase the footprint and capacity of the site. The site handles the world’s largest container ships and connects road, rail and canal networks directly to the heart of the UK mainland. As part of this project, external concrete surfacing was needed that would deliver long term resistance to the high volumes of HGV traffic using the terminal. After discussions with the contractor, the solution proposed was Tarmac’s TOPFORCE fibre reinforced concrete with a combination of synthetic macro and micro fibres. TOPFORCE can eliminate the need for some traditional steel reinforcement, making it quicker and easier to place. It offers excellent longterm durability making it ideal for commercial and industrial sites used by HGV traffic. This solution would deliver a saving in both labour and material costs and avoid the budget impact of the rising cost of steel. As well as improving the durability and structural performance, the use of macro fibres also improved sustainability significantly by reducing embodied carbon compared to traditional steel reinforcement. 

The Margam Green Energy Plant is a long-term, multi-million pound investment into the Welsh economy to help meet the country’s renewable energy targets whilst also strengthening the country’s energy security. A durable concrete was required for the storage silo that housed wood chip to feed the plant.For this project Tarmac suggested their TOPROC SY be used as an overlay on the finished concrete slab as a protective high strength screed. TOPROC SY comprises a micro-silica mix with steel and macro fibres designed to give high levels of abrasive and impact resistance. This product is highly suited to heavy industrial areas such as container handling, metal recycling, waste, loading bays and any other aggressive environments. The main benefit is extended length of time the product will perform compared with traditional concrete therefore saving cost on continual replacement.

Resurfacing was required for this busy supermarket and public car park serving Billericay town centre. In addition to replacing the old surface, works included reconfiguring the layout with additional parent & child and disabled parking bays and the creation of pedestrian walkways with clear demarcation. Tarmac’s ULTIDRIVE 6mm asphalt was selected as it has a close texture finish to provide a surface that is both durable and able to resist the effects of tight turning vehicles. ULTIDRIVE is a specialist asphalt with an advanced modified binder that provides enhanced workability during installation. This assists with compaction and finish, especially when hand laying around ironwork. It also provides improved resistance to rutting and deformation from vehicle loading and to scuffing and abrasion from power-assisted steering. ULTIDRIVE has a higher softening point temperature than conventional materials and resists occasional fuel and oil spills.

A new flooring solution was required as part of a large, high-specification selfbuild housing project on the stunning Archerfield estate in North Berwick. Underfloor heating had been specified for the ground floor of the house and it was important that the chosen floor solution would help to optimise heating efficiency. Given the scale of the project it was also important that the chosen screed solution could be installed quickly over a large area to fit within the build programme. Following initial discussions and a successful pump trial the customer decided to use Tarmac’s TOPFLOW Screed C cement based liquid screed.TOPFLOW Screed C is a free-flowing, cement based liquid screed that can be trafficked after just 24-48 hours and dries within 21-28 days. It can be pumped into place and allows large areas to be covered quickly with up to 120m2 laid in as little as 45 minutes. Fast drying times mean it can be laid later in the programme when the building is fully water-tight and still hit deadlines for installation of flooring. It is ideal for use with underfloor heating systems. As a self-compacting screed, it fully encapsulates heating pipes without leaving any voids and is also a more conductive medium than traditional sand and cement screeds, improving the thermal performance of the system. It is also compatible with most cement based adhesives meaning it can be used with a wide range of flooring types.The fast-drying times and early trafficking characteristics of TOPFLOW Screed C enabled other trades to follow on quickly, helping to provide continuity and efficiency within the client’s build programme. The contractor was delighted with the outcome, commenting on how good the material was to work with and on the excellent finish achieved.

The client required a durable, low-maintenance, all-season surface for this 3.3 km stretch of two-way, segregated cycleway in Birmingham that would offer clear demarcation and provide a safe, appealing route for cyclists.ULTICOLOUR, Tarmac’s durable coloured asphalt was chosen to surface this cycleway, in a mid blue colour, to provide clear demarcation from the existing road surface. Using a high performance clear binder it offers brighter coloured asphalts, ideal for demarcation. ULTICOLOUR SMA is BBA HAPAS approved for use on UK highways as a coloured thin surface course and has been in use on UK roads for over 20 years. It has proven to be highly durable, delivering lasting performance, even on highly trafficked roads. ULTICOLOUR can be laid quickly over large areas using standard paving equipment, just like a conventional surface course.

As part of a £44m project to build a major new police operational command centre, surfacing was required for the large parking area and access roads. The parking area would be used by more than 1,200 officers and support staff and a wide range of vehicles from police cars to heavy goods vehicles. Originally an AC 10 close graded surface course material had been specified. However, after early engagement with the surfacing and main contractor, it was clear that a more robust and durable solution was required that could withstand the high volumes of traffic using the site.Tarmac’s ULTIDRIVE asphalt was chosen as the solution. Designed to resist the long term effects of daily vehicle movement, ULTIDRIVE is a high performance asphalt with a smooth and highly durable finish. An advanced modified binder enhances the toughness of the surface, provides improved resistance to scuffing and abrasion from power-assisted turning and reduces softening in hot weather. It also gives enhanced resistance to temporary fuel and oil spills compared to conventional asphalt surfacing.

A private landowner wanted to develop a large multi-purpose agricultural facility for both arable and potential livestock use at their farm in Leicestershire. Part of the requirement was external surfacing, which would need to be hard wearing and deliver long lasting durability in this demanding environment, including regular use by heavy agricultural vehicles. After discussions with the contractor, the solution proposed was Tarmac’s TOPFORCE fibre reinforced concrete with a combination of synthetic macro and micro fibres. TOPFORCE is a fibre reinforced, high performance concrete, that eliminates the need for some traditional reinforcement. Quicker and easier to place than traditional steel mesh reinforced concrete, TOPFORCE concrete offers excellent long-term durability and performance. This makes it ideal for heavy duty flooring or hardstanding applications. This solution would deliver a saving in both labour and material costs and avoid the budget impact of the rising cost of steel. As well as improving the durability off the finished concrete, the use of macro fibres would also improve sustainability significantly by reducing embodied carbon compared to traditional steel reinforcement. 

The client, East Lindsay District Council, planned to build a brand new £7m state of the art Public Sector Hub facility in Horncastle, Lincolnshire to provide office space for the District Council, Boston College, along with Lincolnshire Police and local medical organisations. A sustainable approach was needed towards the construction of the large 220 space car park required to serve the new building to avoid surface run off and flood risk to the surrounding area.  Using Tarmac's ULTIPOROUS meant planning conditions and would keep the car park free from standing water, even after heavy rainfall. It also avoided the need for additional costly drainage systems and was far less labour intensive than alternatives like block paving, which helped saved time and cost for the client. The smooth, even finish also met the client’s requirement for a safe, low maintenance, all weather surface.

This large car dealership in Dorset required a new car park surface for the external paved areas. Planning requirements meant that a porous system was required to enable sustainable drainage and avoid large scale run-off into the surrounding catchment. Using Tarmac's ULTISuDS porous asphalt sustainable drainage systems met the needs of the local planners by managing surface water and reducing direct surface water run-off, but also met the client’s requirement for a safe, accessible all-weather surface for their customers. By eliminating surface water, it also eliminates the problem ice patches that can occur in cold weather conditions. It would also be durable enough to cope with daily vehicle movement and static loading from cars that were on display. 

This large college needed to increase parking capacity for students and staff and commissioned a new 5,500m2 car park. Local planning guidelines encouraged a sustainable approach to drainage to avoid excessive run-off into the local catchment. It would be used throughout the year, so there was also a requirement to avoid standing water during heavy rain. As it would be in frequent use by large numbers of staff and students, the chosen surfacing needed to provide long term durability with minimal maintenance requirement.After discussions with the main contractor, Tarmac’s experienced team recommended ULTIPOROUS, their specialist porous asphalt car park surface. Using a modified binder and open aggregate structure, ULTIPOROUS combines excellent drainage characteristics with long term durability. It reduces direct surface water run-off to help meet planning requirements. It also eliminates the problem of both standing water after heavy rain and ice patches that can occur in cold weather conditions.

Project BriefThe James Dyson Building and the Dyson Centre for Engineering Design at the University of Cambridge officially opened in May 2016.The technology hub was designed by Nicholas Hare Architects and funded in part by a £8m donation from the James Dyson Foundation, and will give some of the world's brightest young engineering students access to advanced laboratories.The Department’s priorities were for a low-energy building (targeting 100kWh/m2/annum total) that would showcase the state-of-the-art work of the Department and be sustainable.The ProjectThe James Dyson Building is located within the Cambridge Central Conservation Area and is also adjacent to the Grade II listed Royal Cambridge Hotel. Care was taken with both the scale and materiality of the building which was closely scrutinized by the Cambridge Design and Conservation Panel.The James Dyson Building provides flexible and highly energy-efficient research, seminar and meeting spaces for post-graduate students at the University of Cambridge’s Department of Engineering.Linked by an atrium to the existing Department buildings, the new facility is located on a prominent and sensitive site within a conservation area and at a major gateway into Cambridge.Much of the concrete frame of the building is exposed internally to assist in maintaining thermal stability and natural ventilation is encouraged using a series of chimneys running through the building.Research groups worked with the contractor to incorporate active stress sensing of the concrete frame and low-carbon, magnesium blocks were also used in the build.A large proportion of the construction cost was met through a generous donation by The Dyson Foundation.Help from Tarmac - Limelite Heritage Lime MortarWe supplied Limelite Heritage Hydraulic Lime Mortar in bulk bags & 25kg bags to the new James Dyson Building in Cambridge.

The challenge was to construct a roof top extension on top of the luxury hotel NOBU in Shoreditch. The plan was to add an additional 1 storey of hotel rooms, suites, dining areas and open terraces that would replace the existing planted roof. The chosen solution was Tarmac Toplight C lightweight structural concrete in a pump mix with the addition of steel fibres, ensuring maximum weight loss of 35% with no compromise on structural concrete performance.By adding steel fibres into the lightweight mix the composite metal deck system could be installed without the need for traditional expensive and slow steel reinforcement across the deck. The use of lightweight concrete, furthermore, reduced the load by 35% which meant the existing structure did not need to be reinforced or under pinned. The construction programme time was also reduced considerably.

A busy Leeds Freightliner container terminal located to the South East of Leeds needed replacement of a number of sections of the external paving. The site is subject to constant traffic and extreme loading, with loading vehicles weighting up to 100 tonnes when carrying a container and daily use by HGV’s. Tarmac’s TOPFORCE fibre reinforced concrete offered the ideal solution. Although TOPFORCE concretes can be used instead of conventional steel reinforcement in some applications, in this case it would be used for added durability and crack resistance in a pavement design containing two layers of steel reinforcement mesh within a 300mm slab. The fibres within TOPFORCE provide three-dimensional reinforcement throughout the full depth of the pavement. This delivers improved abrasion, impact and crack resistance and enhanced flexural strength.Find out more at: https://tarmac.com/case-studies/fibre-reinforced-concrete-for-busy-transport-hub/

The new, purpose-built Community Fire and Police Station on a two acre site in Prescot required a durable surface for the main yard area, car park and access road. This was a large site, incorporated three fire engine bays, a practice drill tower and community meeting rooms. Having replaced two local fire stations it was expected to be a busy station used by a range of vehicles. With each fire engine weighing up to 13 tonnes and using power-assisted steering the new surface would be subject to extreme turning forces. It would need to offer long-term durability and loss of aggregate due to surface abrasion. After considering the options, Tarmac’s ULTIPHALT HD was chosen, a tough, high performance 10mm asphalt with advanced modified binder. ULTIPHALT HD has been proven to deliver enhanced resistance in challenging environments like container ports and distribution centres. The modified binder enhances durability but also helps to maintain workability and aid compaction, even in low temperatures.

This exclusive up-market housing development in rural Somerset, required surfacing for what would become an adopted residential road. Planning requirements specified that a sustainable form of drainage would be needed to gain planning consent. ULTIPOROUS, Tarmac’s durable porous asphalt was recommended. It would allow full infiltration of rainwater to eliminate puddles and standing water even after heavy rain. It would also achieve a safe, all-weather surface for residents and avoid surface run-off into the local catchment. The approach taken, meant that no drains or manholes were required, which is another advantage of using this product for architects and designers. It would also deliver lasting durability, helping to minimise future maintenance requirements.

This new housing development in Leicestershire required porous, all-weather driveway surfacing for the new three, four and five bedroom homes that would manage rainwater and avoid local flooding. Tarmac's ULTIPOROUS provided the solution combining excellent drainage characteristics with proven long term durability and meeting local planning requirements and delivering a sustainable drainage solution.

The Problem:Associated problems caused by damp and flooding are commonplace throughout the UK’s housing stock. Growth of black mould and efflorescence caused by salt transfer can lead to thedelamination of the plaster and there is no simple resolution. Often the only choice left to the housing association or local authority is to remove the original plaster and treat the walls with a Damp Proof Course (DPC), before waiting for it to dry to receive a backing plaster – all at the expense of the landlord or local authority.The Solution: A Modern, Lightweight Renovating Plaster:Limelite Renovating Plaster solves all of these problems. Firstly, it can be applied to damp walls, saving an enormous amount of money for time that would be otherwise spent waiting for the walls to dry out – it effectively controls dampness passing through walls, as well as providing a barrier against salt transfer – ultimately allowing the substrate to dry naturally. Secondly, and crucially, Limelite Renovating Plaster will withstand damp issues caused by future events, which may be likely in properties susceptible to damp and flooding.Thirdly the Limelite plaster system offers Thermal Insulation by drying the walls rapidly, reducing loss of heat and insulating the internal walls to meet modern day standardsThermal Conductivity, λ10,dry,mat, P=50% = 0.17W/m.KThermal Conductivity (k) at 0% moisture = 0.13W/m.KAnother benefit with Limelite plasters for internal use is their fire resistance/protection as a non-combustible product (as defined by BS476:Part 4) which can be assigned Class O in accordance with the requirements of the National Building Regulations and Reaction to Fire = Euroclass A1 Making the Difference for Local Authorities Dudley Council in the West Midlands is among the many local authorities that specify the use of Limelite Renovating Plaster when tackling such issues in social housing.“Where a renovating plaster is required we use the original and proven, Limelite” said Andy Pratt, Specification and Design Manager for Dudley Council, which has been specified by the council for over 40 years.Where existing plaster is sound, a small area of plaster is removed and replaced with Limelite.In more severe cases where the existing plaster is unsound, all plaster is removed and the wall is treated with a DPC before Limelite Renovating Plaster is applied. Limelite Renovating Plaster is also used for patch repairs in areas such as window reveals, where again the damaged plaster is removed and replaced with Limelite.A BBA Approved SystemLimelite Renovating Plaster is a BBA approved solution, when used as the backing plaster in a 2-part system, finished with our High Impact Finishing Plaster - a hard, durable finishing plaster that produces a Grade D impact resistant surface.

The Audley Stanbridge Earls retirement village is an exclusive residential development of 155 luxury retirement apartments and cottages designed around a Grade II listed Tudor Manor house on a 32 acre site near Romsey, in Hampshire. Underfloor Heating had been specified as part of the design and the large floor areas now needed to be finished with floor screed that could be installed quickly and efficiently within the operating windows provided by the main contractor.TOPFLOW Screed A Thermio + offers a higher thermal conductivity than conventional sand-cement screeds, can be laid thinner and fully encapsulates heating pipes without leaving any voids. This makes it ideal for use with underfloor heating systems where it helps to improve the thermal performance and energy efficiency of buildings. All TOPFLOW Screed A products are made from gypsum and are completely cement free, with a binder made from 98% recycled material. This gives it a lower carbon footprint than a conventional cement-based screeds, saving up to 20.45kg CO2e per m2, making it a more sustainable choice.

Funding was secured to renovate a Grade II listed lido in Pontypridd. The lido, which had remained derelict since 1991, was given a new lease of life after the local authority clinched the funding required to restore it back to its former glory. As part of the scheme, the existing derelict buildings would be renovated and the Lido bathing area remodeled into three heated pools. The restoration included external covered showers, heated changing facilities and a learning and historical interpretation centre. The client needed a coloured product that was highly durable, easy to place and maintain, available in a range of colours and, most important of all, capable of retaining its colour and beauty. TOPTINT coloured was recommended as the ideal solution. TOPTINT contains an integral colour pigment which is UV stable meaning that the colour will not degrade from natural sunlight. Also, because a liquid pigment is used the colour is evenly mixed throughout the concrete. As this pigment is integral to the mix it is a long lasting and frost-resistant solution, requiring little on-going maintenance and therefore making it a more sustainable long term solution.
