Great products and innovations as always.” Michael Day, Area Manager at AL Civils.The reinstatement took place on a busy non-residential road on a mild, rainy November day in Malpas, Shropshire.The Results“Innovative products make our life so much easier. Mortar Buoy®, Envirobed® CD534 Flowable and QC10 F 100% makes life easier and saves money.” Michael Day, Area Manager at AL Civils.

Limelite Heritage Lime Mortar, a lime based cement free mortar was chosen for renewal of iconic York Guildhall site. As well as matching the visual aesthetic, the flexibility of Limelite Heritage Lime Mortars allow for slight movement and thermal expansion throughout the life of the building and reduce the risk of cracking. They can also reduce the need for expansion joints to improve the final appearance and along with the ready-to use pre blended formula, reduce build time for the contractor. 

An extensive hard landscape setting for the new Tottenham Hotspur Football Club stadium. The large 11,000 m2 paved area has been constructed in a combination of granite and concrete block paving units. Although the area is mainly pedestrian the brief required that the units be completely and permanently bonded into position. This was achieved using Steintec tuffbond in combination with tuffbed 2-pack Type 35 bedding mortar to achieve a minimum 2MPa adhesion between the paving units and the supporting layers. Steintec tufftop Type 40 jointing mortar was used to complete the installation.

The prestigious EIB HQ in Luxembourg City never fails to impress visitors with its expansive paved setting. Laid nearly 15 years ago the condition of the natural granite sett paving is testimony to the performance and quality of Steintec high performance mortars and the longevity they bring to bound construction pavements.

Ultrascape's BS 7533 compliant mortar paving system has been used to deliver a modern and stylish forecourt outside Swindon railway station.

Work was carried out by specialist civil engineering contractor, Britannia Construction and included the installation of 500 tonnes of high quality natural granite and Pennant Sandstone using Ultrascape's Pro-Bed HS fine bedding concrete, Flowpoint rapid setting grout and Pro-Prime slurry primer.

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

The revamp of this regional flagship shopping centre was a time-critical project. During construction, the existing retail businesses and visitor access needed to be kept to a minimum. Steintec's tuffset G was used in the preparation of the bedding, priming and jointing mortars to achieve earliest trafficking wherever possible. The proven capability of tuffset G to achieve this in ONLY 3 HOURS was used to great effect minimising disruption and inconvenience for the duration of the project.

This project employed the BS 7533-101 Type A method of construction (rigid/bound paving over an unbound roadbase) with the use of Steintec's tuffflow permeable paving mortar as part of this SuDS scheme.The Steintec tuffflow system of permeable bedding and jointing mortars was used to construct a SuDS permeable, bound/rigid pavement. The system allows the designer to capitlize on the low maintenance, high durability of a BS structurally compliant bound/rigid public realm pavement, while avoiding the disadvantages of loose bedding and jointing aggregates used in conventional SuDS pavement construction.

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.”

This project combines SuDS bound permeable paving with the most up to date methods of construction in BS 7533-101 and a variety of build-ups over varying substrates including structural concrete, permeable concrete, made up ground and attenuation crates.The Steintec tuffflow system of permeable bedding and jointing mortars was used to construct a SuDS permeable, bound/rigid pavement. The system allows the designer to capitlize on the low maintenance, high durability of a BS structurally compliant bound/rigid public realm pavement, while avoiding the disadvantages of loose bedding and jointing aggregates used in conventional SuDS pavement construction.

MJ Quinn and subcontractors, HT Installations Limited, have used UltraCrete’s market-leading Flowable Installation System to repair a faulty carriageway frame and cover on the B4299 in Carmarthen.BackgroundA large section of a rural road in Carmarthen was severely damaged. The area in question is located at the bottom of a hill and over time, the relentless force in which cars and tractors have hit the road surface has severely deformed the surface.The consequence of this damage also caused structural damage to a nearby carriageway frame and cover.The ChallengeLocated on the B4299, this rural road is the main thoroughfare for the village, with tractors and cars using the road daily. The repair needed to be carried out quickly to minimise disruption, and most importantly, it needed to be a first time permanent repair to prevent any further disruption and damage to the surrounding road surface.In this instance, HT Installations Limited, the subcontractor working on behalf of MJ Quinn, the main contractor for Wales for Openreach, were only responsible for repairing the frame, cover and trim back area. However, in order to prevent further deterioration caused by the deformed road surface, HT Installations went above and beyond and replaced the heavily deteriorating asphalt on the CW2 frame and covers leading edge. This would ensure a longer life expectancy for the new carriageway frame and cover installation and avoid costly return visits.The SolutionHT Installations Limited utilised UltraCrete QC10 F flowable fibre modified concrete to repair the brickwork chamber and their Envirobed® Flowable Installation System to install the replacement CW2 frame and cover – a process used by Openreach for all their carriageway repairs.To begin, the entire area was excavated and spoil removed. The contractors assessed the chamber and utilised the Mortar Buoy® installation aid within the chamber as an alternative to formwork/shuttering. They proceeded to mix and pour UltraCrete QC10 F, rapid set flowable concrete, to repair the damaged concrete chamber. Utilising Mortar Buoy® significantly speeds up the repair process, helping to save you time and money.QC10 F sets in less than 20 minutes, so a very short time after being poured, Mortar Buoy® was re-inflated inside the chamber and the CW2 frame dropped into position ready for levelling with the existing road surface. A sand bund was then formed 50mm beyond the flange edge, as opposed to shuttering, to retain the flowable mortar.UltraCrete Envirobed® CD534 Flowable Red was mixed and applied to fully encapsulate the frame flange up to 20mm above and 50mm beyond the frame edge. Envirobed® CD534 sets within 20 minutes, allowing the sand bund to be swept clear and site prepared for hot asphalt application, really quickly.ResultsThanks to the rapid high strength gain and setting superior performance qualities of UltraCrete’s Flowable Installation System, HT Installations were able to carry out their repairs quickly, safely and permanently, much to the delight of MJ Quinn, Openreach and the local residents.

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.

Road users in Kensington Church Street in Bayswater, are now enjoying a peaceful commute after Openreach and Centercomms Ltd replaced a long-standing failed access cover using UltraCrete’s market-leading access cover reinstatement materials.BackgroundClient Openreach, and contractors Centercomms Ltd, were once again required to repair a failed ironwork chamber on a busy central London street – the longest standing failed unit on their work stack.The ChallengeThe troublesome unit was located on Kensington Church Street in Bayswater – an extremely difficult and busy area in Central London. Working in London can be challenging as traffic management permits can be difficult to obtain and, due to heavy traffic, all work must be completed within 9.30am – 3.30pm.As well as a tight turnaround, upon arrival it became clear very quickly that chamber was damaged and the brickwork needed to be excavated.The SolutionWith this in mind, contractors Centercomms Ltd, working for, and on behalf of, Telent, chose to use UltraCrete’s market-leading maintenance solutions to replace the failed unit. UltraCrete has a reputation of providing the industry with expert and approved materials that reach required compressive strengths very quickly, helping operatives to complete installations before the 3.30pm deadline.To begin, the damaged brickwork was removed and timber shuttering installed using UltraCrete QC10 F. This fast, strong and easy to use flowable concrete provides an extremely robust repair in just 20 minutes.Using the SG Pam Install Plus frame installation system, Centercomms Ltd carefully placed the frame and used a string line to ensure it was level with the existing road surface.Once in position, Envirobed® CD534 Red high performance bedding mortar was applied to the inner face and chamber top and the timber shuttering was then placed 50mm beyond the flange.After Envirobed® CD534 Red had fully cured, Envirobed® CD534 Flowable Red was mixed and poured to fully bed and encapsulate the frame to a minimum depth of 35mm.To complete the installation, operatives returned the lid into position, applied SCJ seal and tack coat spray to the vertical edges of the existing road surface and frame ahead of the asphalt reinstatement.ResultsThe entire installation took just two and a quarter hours to complete, much to the delight of the client, contractors and road users.

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.” 

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.”
