When refurbishing a building in the heart of London, innovative building solutions and construction processes are necessary. That’s why Schüco FWS 50 curtain walling and AWS 70.HI side-hung windows were specified for the renovation of University College London Hospital’s (UCLH) Ear, Nose & Throat Department.Being located in such a central and busy area, it was decided that a prefabricated façade system would be the ideal solution. The key challenge was for this system to be installed as a complete unitised panel on site while still using a standard stick system.The building façade comprises 28 prefabricated bays, each 4 m wide, constructed as hybrids of traditional hand-made bricks, precast concrete, aluminium and glass.

PROJECTED BRICK DETAILING USING MARSHALLS CONCRETE BRICKS FORMS THE CONTEMPORARY ARCHITECTURAL FOCUS OF THE TIMPSON UNIVERCITY.The retail service provider group’s new training centre near its head office in South Manchester.Designed by the Manchester office of award-winning architect practice tp bennett, the purpose of the new state-of-the-art building, known as The Nest, is to host training to 500 staff a year, including ex-offenders and those on day release.“We wanted to create the best training facility in the UK; a welcoming and comfortable building that inspires people to be their best within an environment that is fun, calm, spacious and collegiate,” explains Timpson Facilities Manager, Natasha Nelson.The single-storey, 9,258 sq foot brick-built building comprises a boardroom, training and meeting rooms as well as a breakout space and garden area. Originally, the project architect, whose intent was to add architectural interest using a projected brickwork technique, specified a white clay brick, externally.Working alongside the architect and main contractor John Turner Construction, brick expert and LBT Brick & Facades Ltd Commercial Manager Steven Leggott, specified Marshalls Castleton Stock facing bricks, he explains: “Originally the architect was looking to specify a white clay brick. I proposed some alternative options and the Castleton Stock brick came out as the preferred choice. It provided a competitive clay alternative – it’s a concrete brick that met both aesthetic and technical requirements.”THIS BRICKWORK DETAIL PROVIDES THE PERFECT BACKDROP TO THE BUILDING’S SIMPLE YET EFFECTIVE SIGNAGE.Running the full length of the entrance façade, Marshalls Castleton Stock facing bricks add texture and relief. The bricks have been laid using a natural mortar to create a projected pattern from the ground up to a two-third height, with the bricks protruding 20mm. This brickwork detail provides the perfect backdrop to the building’s simple yet effective signage.The Castleton Stock facing brick is part of the Marshalls frogged, contemporary range. With an industrial chic feel and a smooth face, it works well when creating modern designs.TIMPSON UNIVERCITY SITE HAS SAVED 12.4 TONNES OF CARBON.What’s more, this particular brick is Green Guide rated A+, as Marshalls concrete bricks have significantly less embodied carbon than clay bricks – almost 49% less over their whole lifecycle. By selecting the Castleton Stock brick as an alternative to a traditional clay brick, the Timpson UniverCity site has saved 12.4 tonnes of carbon.Commenting on the finished building Timpson Group Facilities Manager Natasha Nelson said: “The building is a huge hit with our colleagues and external clients, from the minute you approach the entrance, the brickwork detail makes such a first impression - setting the professional tone for what’s happening inside!”

The Crouch End Picturehouse in North London is an interesting example of how Kalwall® can be used to convert an ugly 1950’s concrete building into a state-of-the-art space suitable for the 21st Century.  •   This project by Panter Hudspith Architects forms part of a wider initiative within the London suburb of Haringey aiming to re-establish the area as one of London’s cultural and arts centres. The result is a remarkable transformation of a building, originally a factory then an office, into a £4.5 million cinema complete with café, bar, restaurant and community rooms.  •   The unique style of this four-screen cinema has attracted much interest, not only because of the dramatic transformation but also because of its new external elevation. •   The use of Kalwall, coupled with other sustainable measures including solar panels and a green wall, means the picturehouse has achieved a BREEAM rating of Very Good. The Solution Panter Hudspith Architects replaced the original curtain wall and specified Kalwall® for the front elevation. Unusually, this unique translucent cladding is fitted with a tight 150mm wide grid, known as Verti-Kal™, which not only serves to emphasise height but is the first of its type in the UK. On this scheme the Kalwall panels also insulate to 0.78 w/m2 making the building eye-catching and sustainable. Unlike conventional glazing, Kalwall eliminates shadows and glare and the stark contrasts of light and shade. The system also enhances simplicity by eliminating the need for blinds, curtains or solar control. Even on cloudy days, the interior is bathed with natural daylight, which means less artificial lighting and, because Kalwall is highly insulating, energy costs are reduced. Kalwall is increasingly being used in the UK for new buildings and also for the refurbishment of cladding or rooflights on aged buildings. One of the main attractions of specifying Kalwall is its unique effect on both the interior and exterior. Although translucent, it offers the big advantage of privacy while the elevations appear crisp and simple. When illuminated at night they emit an inviting ethereal glow.  The CommentsArchitect James Jeremiah comments, “This is the first time we’ve specified Kalwall and it fulfils our vision of retaining the modernist characteristics of the building. One of our original concepts for the building was of a zoetrope (one of the earliest forms of moving image) and there’s a strong history of using transparency in films with people moving behind the shadows. We felt the Kalwall system was a very good fit for what we wanted to achieve”. Amanda Birch, Technical Editor Building Design writes, “To appreciate fully the building’s transformation, it is best viewed from the street. The concrete structure has been retained along with its striking line of concrete columns, which are now a strong feature of the front elevation. The original coloured insulated glass panelled system has been replaced at first and second floor levels with Kalwall’s 75mm thick insulated cladding system creating a dynamic façade that is particularly effective at night.

Project:Thames Park Client: Department for Education (DfE) Contractor:Bower & Kirkland (B&K) Architect:Stride Treglown Value: £24m Location:Grays, Essex GIFA: 6950m2 Completion:September 2022SOLUTION Innovaré supporting Bowmer & Kirkland delivered the £24m Thames Park School through the DfE Offsite Framework. The proposed designs and plans for the school were carefully considered, with collaboration between project partners, staff at the school and the Design Review Panel at Thurrock Council. The Innovaré team managed the structural design, manufacture, and installation. Thames Park was constructed utilising a hybrid offsite approach incorporating Innovaré’s i-FAST panelised solution, integrating windows and external brick slips to the ground floor and cladding above. Roof cassettes were by Pasquils and pre-cast concrete floors by Creagh Concrete, with M&E specialist DBS supporting the fit-out solution for the plant room offsite. OUTCOME Taking the majority of the build offsite and using scaffold-less installation improved onsite health and safety. The project was 100% safe with zero hours lost to RIDDORS and accidents. Utilising offsite manufacture also allowed for a higher quality finish, with a robust testing and quality checking system to reduce ongoing maintenance. Basing the design on CIBSE, BS – U-Values as low as 0.21w/m2k were achieved, reducing energy requirements for the lifetime of the school. Insulated wall panels and precast concrete floors also allow enhanced temperature management, reducing heating and cooling costs and associated carbon output. Innovaré’s input assisted in the delivery of ‘Configure Offsite 3.0’ – a mature standardised yet flexible school solution, designed to exceed the stringent requirements of the DfE’s output specification and also reduce construction duration by 30%. The collaborative approach taken during the project culminated in enhanced Pre-Manufactured Value, reduced onsite construction time and minimised environmental impact. This further improved construction quality and health and safety.Paul Griffiths, Chief Executive Officer of Osbourne Co-operative Academy Trust, said: “We have worked very closely with the main contractors Bowmer & Kirkland and the DfE on the design of our new school and we feel the educational principles and digital vision that drive this project have been keenly thought through, so that this development delivers more than just a state-of-the-art school, but also a community facility that serves the local area and enhances the landscape in which it sits.” Headteacher of Thames Park, Kam Bains, said: “We are delighted and excited by the opportunity to deliver outstanding learning facilities and a permanent home for the wonderful students at Thames Park Secondary School. Thurrock students deserve the very best education in a happy and high achieving school.” Thames Park Secondary School

Project detailsIn 2008 the MPT consortium* was awarded the Manchester’s Metrolink phase 3a extension project, a 49 stop, £275 million extension to the Manchester Metro. The new build allowed contractors to shop around for the best products for the job, but one essential product could not be found. Throughout this three-year development, best practice and user health and safety have been the priorities. Steps were designed to minimise risk of trips and slips for pedestrians, the disabled and visually impaired. Each of the 1,400 pre-cast concrete steps on the new platforms required a non-slip front edge and MPT scoured the world for suitable products. The design criteria required that the nosing would be: Suitable for heavy use in an external environment Compliant to the Building Regulation Part M Providing a solution in accordance with BS8300 2009 Inner B Code of Practice, against the finished concrete in both wet and dry conditions Our solution Adrian Rowe, MPT Engineering Manager and his team tested a wide range of products, short listing three, including Firm-Step Edge®. Our product met the design criteria but was unavailable in the required specification, size and colour. Not wanting to let this opportunity pass us by, we took up the challenge and developed an exclusive version of Firm-Step Edge® in black, with a 70mm tread and 55mm riser. “Watco was brilliant in sorting out our problem, giving us excellent service throughout. They understood our needs and delivered prototypes in a week. They also developed an exclusive version of their Firm-Step Edge®, in the specified black shade, with a 70mm tread and 55mm riser that fitted on to the rebated precast step to keep the nosing flush. It also had perfect internal angles so it sat snugly on the standard profile of the nose on the precast concrete steps.” Following the first installation in February 2011, Firm-Step Edge® is now being screwed and bonded to steps at every stop along the 49 stop extensions. Firm-Step Edge® is an economical, quick to install safety feature. Firm-Step Edge® offers a tough GRP base that is resistant to stretching, warping and swelling. We offer two grades; medium for internal and coarse for external stairs, both of which are easily glued using Watco Adhesive Mastic or drilled for screw fixing. The textured finish offers excellent slip-resistance and a chamfered back edge minimises trip potential. Available in white or yellow, Firm-Step Edge® can be cut on site if required using a hacksaw or similar cutting tool or we offer a cut to size service. *MPT (M. Pact Thales) is a consortium comprising Laing O’Rourke, VolkerRail and Thales UK.

AMP Clean Energy Ltd.End User: Commercial Site in ColchesterProduct: Coniston Wall Mounted Canopy with a Goalpost Frame, on BracketsFrame Colour: Hipca WhiteSize: 5m x 4.975mInstallation Date: March 2024The BriefAMP Clean Energy supply batteries and storage for their clients, among other services and in January 2024, AMP’s Head of Delivery reached out to Able Canopies as they were looking to add a shelter within their battery site in Colchester, Essex.They were specifically looking for a commercial canopy that could be installed into their existing concrete base, that was freestanding and could be left in strong winds. They also required the canopy to be dismantled and used elsewhere as it was only required for 6 months in its current position.The SolutionThey had seen the canopy we installed at Air Products plc and wanted something similar, that matched the above specification with a quick turnaround. Our canopy with the quickest turn around is the Coniston which can be supplied as both a wall mounted canopy and a freestanding canopy.After discussing the differences between Welford Dome Freestanding Canopy (to match the canopy installed at Air Products Plc) and the Coniston, AMP Clean Energy opted for the Coniston Wall Mounted Canopy.Whilst the Coniston is a permanent structure that has been engineered to withstand all that the UK weather has to offer, we can also dismantle the canopy and install elsewhere if required. This made it the perfect solution for AMP Clean Energy.As mentioned above, they originally wanted a freestanding canopy, we can provide this with the Coniston by using a ’goalpost’ frame this will also give them the minimum heights at the front and rear of the canopy. Using brackets, we also secured the canopy onto the existing concrete wall for additional support and rigidity.The InstallationThe existing concrete wall that we planned to install the canopy against was only 2.7m high which would leave a 400mm gap between the height of the canopy and the top of the wall, we therefore used a PVC flat board to bridge the gap. Whilst this could not guarantee a watertight seal, it would dramatically reduce driving rain coming in from the back of the canopy.AMP Clean Energy required a quick turnaround, and, on this occasion, we were able to achieve exactly that. From the time of the initial enquiry to the time we completed the installation, the entire job was completed within 7 weeks.After SalesIn July 2024, we returned to site to temporarily remove the roof so that the staff at AMP Clean Energy could remove the batteries. As mentioned, they wanted a canopy that could be taken down and whilst the Coniston Wall Mounted Canopy is a permanent structure, we can take them down if required, or in this case, remove the roof then add it back when required.Here’s what AMP Energy Clean Energy had to say about Able Canopies:“Excellent Job!”Service: “Excellent”Installation: “Excellent”Product: “Excellent”Would you recommend us? “Yes”

The architect has created a connection with the outdoors in, utilising large fixed rooflights from Glazing Vision to bring daylight into the house and frame the surroundings.‘The most beautiful spot in the Netherlands’; that is the description of this country house in the marina ‘t Raboes according to the owners. Located on the Eemmeer, a place in the middle of nature, and away from the hustle and bustle of city life. The architect has created a connection with the outdoors in, utilising large fixed skylights from Glazing Vision to bring daylight into the house and frame the surroundings.Bringing in daylight with large minimalist skylights was a key requirement for the architect. The horizontal application of large glass surfaces demands a lot from the design and after many discussions, the architect was confident that Glazing Vision was the rooflight manufacturer that could implement what they had in mind.No framework in sight. Insulated glass with excellent insulation values. Glass that blends seamlessly into the architect’s design. A way to bring the outdoor feeling inside.Three multipart skylights have made this architectural vision become a reality.The back-to-back angles fit in very well with the rest of the modern contemporary interiors. To make it possible to darken the rooms, Glazing Vision has applied custom-made sun protection from Topshade.At the spot where the river Eem flows into the Eemmeer, architect De Kort van Schaik designed the country residence ‘t Raboes. The clients wanted to create a place where they could fully experience nature, but also withdraw from the hustle and bustle of the city.The house consists of three parts, connected by three covered terraces. Concrete walls and floors which blend seamlessly into the environment and large windows that frame the polder landscape.All energy on ‘t Raboes is generated locally. The solar cells on the roof of the marina building supply electricity. A heat pump that uses the surface water of the Eemmeer provides heating for the house and swimming pool.In the living areas, wood stoves have been used, all which use wood from their own grounds, providing readily available extra heating capacity.A beautiful contrast is created by the yellow epoxy bathroom furniture, designed by Sabine Marcelis. A piece of furniture consisting of a bath, wash bath and shower stands as a free-standing sculpture in the concrete bathroom. The skylight forms a completely frameless glass roof, which gives you the feeling of being outside even more.Sabine Marcelis states that she has designed her dream bathroom. The subtle rotation of the furniture gives you a fantastic view of the landscape from the bath.Taken aback by this stunning property, the architectural press has been impressed with all aspects of the design. De Volkskrant gives the Huis op ‘t Raboes five stars. “The Rotterdam architectural firm De Kort Van Schaik designed a house in which you live with the elements and at the same time are protected against them, thanks to a thick concrete coat.”

Floor Painters Limited, have used UltraFloor to complete a 2,100 sqm industrial flooring project at a historic steel forge.Experienced industrial flooring experts, Floor Painters Limited, have used a number of UltraFloor materials to complete a 2,100 sqm industrial flooring project at a historic steel forge in Lincoln.BackgroundBuilt over 100 years ago, the existing floors in the steel forge were damaged and unsafe. After careful consideration, it became clear that replacing the original concrete floor was not a practical option in terms of time and cost.The ChallengeThe steel forge remained fully operational throughout the project and so the challenge was to find a range of flooring materials perfectly suited for industrial use and that could be trafficked quickly so as not to disrupt any work being carried out.The SolutionWith decades of expertise, Floor Painters Limited knew UltraFloor materials were key to a successful outcome.After removing the damaged concrete floor, the concrete substrate was sealed using UltraFloor Prime IT Multi-surface Primer. Formulated to promote adhesion to all UltraFloor smoothing underlayments, Prime IT Multi-surface Primer is pigmented pink for excellent coverage control and is proven to reduce pinholing, minimising the risk of costly failures. With a coverage rate of 200sqm at 3:1 dilution, Prime IT Multi-surface Primer is a must-have product for all flooring installation projects.The following day, Level IT Base was applied, via pump, at an average depth of 50mm. Level IT Base is a heavy duty, deep fill smoothing underlayment, formulated to build depths of up to 50mm thickness. Level IT Base also boasts a high compressive strength – an important requirement for all industrial flooring applications.Once Level IT Base had cured, Level IT Top was pump applied to an average depth of 10mm and left to cure. Ideal for use with Level IT Base, Level IT Top is a heavy duty, abrasive resistant surface finish, designed for use as a wear surface, and can receive forklift traffic after only 36 hours – the ideal product for warehouses and manufacturing facilities where downtime is not an option!Both Level IT Top and Level IT Base can be pump or trowel applied for ease of application, are moisture tolerant, have a 30-40 minute working time and can receive foot traffic after just 3 hours.To complete the installation, the cured floor was then prepared by industrial grinding before the application of two coats of a solvent free epoxy coating – resulting in a flat, hard-wearing, safe and fit for purpose floor.ResultsThe project was completed in six stages, over 36 days, carrying out between 300 and 500 sqm a day, depending on the work space made available. On completion of the project, Terry Rossington, Director of Floor Painters Limited, commented: “Our client was very happy with the standard of the finish and the upgrades made to their working environment, which has improved both visual appearance and functionality of the floor.”

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.

In April 2016, the world-renowned London School of Economics announced that Grafton Architects were to design their next major project. The Marshall Building at 44 Lincoln’s Inn Fields, built by Mace Group, includes an extensive two-storey, mixed-use basement that will house plant areas, squash courts, changing facilities and a sports hall, covering a total of over 2,250m2 of floorspace and presenting quite the project for Newton Specialist Contractor Cast Contracting Ltd (CCL).Newton Specialist Contractor CCL were appointed to design, supply and install the waterproofing by principal contractor Mace Group in late 2019.To provide a completely dry, guaranteed solution on such a high profile project, CCL recommended the Newton CDM System.Otherwise known as Type C waterproofing, the CDM System is the safest and most reliable form of waterproofing.Prior to installation, CCL applied Newton 906 Lime Inhibitor to the new slab to prevent free lime from the concrete from affecting the drainage membranes. The Type A liquid waterproofing membrane Newton 103-S was also applied internally to many of the concrete surfaces as a barrier to water.With preparations complete, over 2,250m2 of Newton 520 eco membrane was installed to the floor and over 570m2 of Newton 508 membrane installed to the walls to create the Newton CDM System. A drainage system of Newton Basedrain channels also directs any water captured by the membranes to the point of discharge, and the whole system was sealed with Newton OverTape.Despite requiring dedicated delivery slots, and working to an extremely tight program of work, CCL were praised on the quality and speed of their installation, which was completed well within the time limit.The Newton recycling service was also a great success, recycling 115 kg of HDPE waste and therefore preventing over 132 kg of CO2 emissions.

Knolly’s House, a residential block of flats in London, required refurbishment works to the internal communal walkways and concrete stairwells as the existing waterproofing had reached the end of its serviceable life. The waterproofing needed to be fast cure as the communal balconies were the only access to the flats. Therefore, Proteus Waterproofing specified Pro-BW® Plus system.High Performance WaterproofingAs constant access was required by the residents, a fast cure waterproofing system was vital. Pro-BW® Plus was selected as it can be fully installed in three stages, each only taking forty-five minutes to cure before allowing foot traffic. Pro-Aggregate EM was incorporated for a slip resistant finish. Proteus Waterproofing worked closely with the Proteus Approved Contractor to ensure the project was completed to a high standard, including an aesthetically pleasing finish.Health and SafetyTo minimise disruption to residents, particularly on communal walkways which may also form the fire escape routes, the waterproofing system needed to be fast cure. Proteus Waterproofing’s liquid applied systems are cold installed and therefore remove the risk of fire to the building. The low noise application also allowed the Proteus Approved Contractor to complete the works safely.Long Term PerformancePro-BW® Plus is a high performance, rapid curing protective waterproofing membrane for balconies and walkways making it ideal for refurbishment where structural movement has occurred. Pro-BW® Plus reduces installation time from days to hours. Suitable for a variety of external applications, Pro-BW® Plus can be installed on concrete & asphalt for communal and private balconies, walkways, staircases and pedestrian ramps. As it is a cold applied installation, the system meets health and safety criteria by minimising risk to both operatives and members of the public. Pro-BW® Plus is BBA Certified and manufactured in the UK.

At this new-build shopping centre in Shepherd's Bush, West London, the new underground car park was experiencing high levels of water ingress through two movement joints that had failed. Newton Specialist Contractor ASF Waterproofing, who are specialists in injection resins and structural repair work, was therefore called in order to provide a quick solution and fix the leaking joints.Following an initial investigation, the technical team from ASF decided to use the 5-part acrylic rubber sealing resin Newton 324-SR to seal the joint, as it reacts to form a very durable and flexible seal that exhibits exceptional adhesion, making it ideal for movement joints.ASF began by drilling holes at angle into the concrete, and at regular intervals for the 10mm injection packers above the joints. The injection packers were then fitted to each hole, and foam backing rod was used to temporarily block the joint and prevent uncured resin from escaping as it is injected.The five components of the PC 509 Rubber Acryl are mixed to make two solutions, whilst the curing time of the resin can also be adjusted by changing the quantity of initiator used. The resin was then injected through the packers and into the joint using a three-component stainless steel pump.Finally, once the resin was cured and the joints were effectively sealed, ASF ground back the surface of the concrete to either side of the joints and applied Newton 106 FlexProof, a flexible liquid waterproofing material, to provide a final protective seal and finish the job.With two leaking movement joints in a finished structure, the client required a swift resolution to get the area back into use quickly. With the benefit of Newton’s advanced resin and waterproofing products, ASF got to site and delivered the sealed joints within the client’s tight timeframe.

Kings Cross has been under development for more than a decade with commercial and residential structures dominating. Now there are new life science labs being built by developers Ardmore. Their architects Bennetts Associates took inspiration from The Arbour at Walthamstow and pushed to use Site Strocks using the abundant London clay being extracted for the piling and deep basement on site. HG Matthews took the clay and using the new tooling invested for the Site Strock project to process it to the desired mix. This was the first project to properly test off-site material for compression and flexural strength, compression and flexural strength of the clay mortar and fire testing. Passing each hurdle then led to 6m high non-loadbearing walls in the basement to line the building rather than more concrete blocks. Clay blocks mean a better air quality, better humidity performance with good thermal mass. The use of Site Strocks at this scale and by such big developers and contractors really showcases the issues faced by these materials and the solutions found in using them, some provided by HG Matthews, others found through discussion with the contractor. For instance the blockwork sub-contractor was unsure about how to build with clay block and clay mortar so we invited them to the factory for a demo build along with architect and contractor representatives. It soon emerged that this was an easy and non-controversial process and the work commenced. Later bike racks were installed using the standard fixings, short screws intended for use with concrete. After initial problems the contractor found longer fixings with some help from us and the bike racks were fixed. Building on this scale with site material in central London is ground breaking in more ways than one, it starts to open the door for lower emission, circular economy materials to be used anywhere and everywhere.

Modular buildings are becoming a more popular solution as they demonstrate cost savings, shorter construction time and sustainability benefits. Go Modular Technologies (UK) Ltd manufactured ten flats constructed by nine large modules on three levels over the concrete commercial ground floor for this project in Poole. We were able to offer an affordable A2 fire rated solution to finish the building envelope which resulted in the facade being completed in Hardie® Architectural Panel. The planning approval was originally for render and buff brick so we were able to provide a similar look with our Smooth Sand texture which was chosen in three of our core colours to give this coastal location a modern and contemporary look.

Becherovka is part of the Pernod Ricard group, one of the largest producers of spirits and wine in the world. CAPEXUS was given the task of creating an office with a more distinctive and prestigious appearance, one that would be comfortable, feature interesting materials and, last but not least, be practical. The unifying element of the new offices is a more industrial concept. Not to be overlooked is the open ceiling with its visible concrete beams and ducts. The exposed materials in combination with the wooden furnishings and Forbo’s Allura Wood and Material luxury vinyl tiles create a pleasant atmosphere for work, business meetings in the conference rooms and relaxation.

CHALLENGE The first of its kind for Quebec, the “living street” required a paving grid that would provide multi-purpose access along the street whilst also allowing for the aesthetically pleasing natural look to be maintained. A woonerf is a living street that is traditionally implemented as a traffic calming aid and to enforce low speed limit areas. They are often shared space streets where equal priority is given to all modes of transportation including automobiles, bicycles and pedestrians; usually with separate rights of way. The province of Quebec was looking to do a “pilot project” in the city of Montreal to create a woonerf that would not only provide the required access, including disabled access but that would also have a long-lasting beneficial impact on the environment. They were looking for an environmentally friendly ground reinforcement product which would provide the strength and durability required for a heavily used area. As a “living street”, the product needed to allow the growth of natural vegetation and contain no harmful preservatives which could affect the environment in which it is placed. The harsh weather conditions in Quebec also needed to be considered. With such extreme conditions in both winter and summer, the material needed to withstand the temperature fluctuations. Ground reinforcement products traditionally used such as concrete are susceptible to cold crack in winter as it is a porous material. As a requirement, the desired product was to absorb only limited heat in order to promote growing vegetation. The only suitable material for a project with such challenging conditions was hanit®’s recycled plastic heavy duty ground girds, with their durability and environmental credentials meeting the requirements.SOLUTIONhanit®’s Heavy Duty Ground Grids are manufactured from a blend of high-quality recycled plastic polyolefins extracted from post-industrial and post-consumer mixed waste plastics. Heavy Duty Ground Grids have a high impact resistance which makes them suitable for all vehicle access. They have an interlocking system which improves stability and also allows for quick and simple installation. As the woonerf needed to provide numerous different access levels it was important that the Heavy Duty Ground Grids were versatile. They can be filled with either grass, seed/topsoil or gravel. For this project, wheelchair access was provided through a gravel filled pathway.The rest of the “living street” was mostly completed with grass filled areas. As hanit® products transfer limited amounts of heat, they dry out the soil less than concrete. This works as a benefit to the vegetation growing through the grids. Recycled plastic material is not porous and therefore does not absorb any moisture. This gives added benefits in the winter as when absorbed moisture freezes in concrete it causes cold crack. Their open structure also allows for quick infiltration of any rainwater into the ground allowing for sustainable urban drainage requirements to be met.hanit® Heavy Duty Ground Grids are strong and durable and require no maintenance. They are not affected by weathering and decay; therefore once in place, they have a much longer lifespan than any other competing products. Made from 100% recycled material, the woonerf has been an extremely sustainable project. Providing Montreal with a living street has not only added more vegetation to the area but also allows the city to contribute to an environmentally responsible sustainable urban drainage solution. As the products are chemically inert they do not affect the environment and are harmless to all flora and fauna. In total the project has used 8,500 units of Heavy Duty Ground Grids. This equates to almost 77 tonnes of recycled plastic waste which has been saved from going to landfill. The woonerf has been an extremely well celebrated project that has won prizes for its conception and green initiatives. “I recommend Les Dalles Vertes (Heavy Duty Ground Grids) to all my clients. We laid out nearly 30,000 square feet of these pavers for the Woonerf project and it took us half the time and resources that were required to install the old concrete grass pavers." - Tony Scirocco, Ventec
