Delta Registered Installers Timberwise (UK) Limited were called upon to offer a waterproofing design to this Grade II Listed property to meet the requirements of BS 8102:2009 to achieve a dry habitable living space, defined as a grade 3 environment.

The brief for this project was to design, supply and install a bespoke and sympathetic waterproofing solution to a Grade II listed, commercial structure with an impractical damp basement.Delta Registered Installers, MacLennan Waterproofing worked closely with the Principal Contractor, HB Projects to achieve a Grade 3 habitable space whilst preserving this historic structure.The Co-op shop in Petworth Village, provides the local community with everything they need, whether its household essentials or a place to meet friends.The site incorporates two Listed Buildings, including part of a Listed Church. The store applied for listed building consent to reconfigure its ground and basement floors, to increase the retail floor space and improve the functionality of the store.When designing a waterproofing/damp proofing solution in a historic building or a structure of architectural interest, additional design considerations should be employed during the design stage to maintain preserve aesthetic and structural integrity of the structure/building. The waterproofing design should be sympathetic in application whilst offering a robust solution.Care consideration should be applied when specifying products to ensure they are ideally suited for meeting the complexities of listed building requirements.

A recent upgrade to the prestigious Empress State Building for the Metropolitan Police was conducted by main contractor, Overbury.As part of the works, stainless steel shelving by GEC Anderson was specified to the vistor’s property store room. The room was very irregularly shaped and so the shelving (5 tiers of 500mm wide shelves) was specially made to suit. A total of 75 metres of shelving was supplied and installed by GEC Anderson for specialist sub contractor, BA Joinery.

Over 200 Optima windows and doors from Profile 22 were installed in an £11 million community hub in Leeds city centre.Westerton Walk in Leeds city centre is an extra care housing development comprising 63 one- and two-bedroom flats with care services, shared lounges and dining facilities. It has been built on a vacant Leeds City Council-owned site and has createda dynamic community hub.

Optima windows were chosen for the construction of 18 houses, 38 flats and two retail units as part of a regeneration scheme in Maidstone, Kent. Housing association Golding Homes has invested £50m in a three phase regeneration project to transform and improve the former Park Wood estate in Maidstone. The scheme involved providing over 200 new homes, mainly family houses, as well as new community facilities including new shops, and a much wider package of investment to improve the local area.

The chosen colours for the brighter abstract paving zones are from our very own recycled glass range called Spectrum®, the glass chippings are of the smallest size available and average around 3mm. The recycled glass is always tumbled (no shape edges) before colour coating begins which is completed in-house to guarantee a colour consistency and UV stability.The striking and fun paving zones SureSet installed feature four bright colours of;Lemon and limeTutti fruityAquaUltramarine blue.The colours were separated using straight aluminum edging provided by our supplier Dural UK Ltd. To keep it fun and interesting triangular shapes were incorporated into the design. These increate areas of abstract triangles were installed by hand using a hand float, to ensure the coloured resin bound glass had the best finish.

The Northern Hub required improved and increased train services via direct links between Manchesters Three mainline stations and a new direct link to Manchester Airport. SureSet helped redevelop these areas by installing two mixes of Resin Bound Paving to run next to the viaduct, which also includes entrances to step areas and ramp ways. The colour Tuscan Barley Butter a dark red mix with tones of gold and yellow, and Bronze which has more browns and greens, were then used in conjunction with a traditional concrete slab. SureSet provides a durable, accessible, low maintenance surface that will last.

The Riverside development in Rochdale includes two nine storey apartment blocks comprising a mix of 240 one- and two-bedroom properties for private rent. The Rochdale town centre Riverside regeneration project also includes a 147-bedroom hotel and 43,000 square feet of office space. The Fire regulations which apply to high-rise living accommodation meant that the kitchens in the apartments would require a fire suppression unit complete with sprinklers to be fitted. These units need to be installed and maintained by a specialist engineer and can also cause damage within a property should they be activated due to a fire.  Therefore, the Firechief Kitchen Stove Guard was chosen as an alternative, unobtrusive design-led fire prevention solution. 

The Wilberforce Trust is a charity dedicated to helping and empowering those with sight and hearing loss and impairment in the York and North Yorkshire area to live fulfilling and independent lives. The Trust had tenants in community based supported housing and family homes around York but wanted to deliver an innovative ‘extra care’ housing scheme designed especially for people with a visual impairment and other disabilities; the first of its kind in the area.Wilberforce House offers 30 one-bed, open-plan purpose-built, self-contained apartments along with a Living & Learning Zone – providing education and leisure activities – a courtyard cafe and offices for the Trust itself, all set in four acres of accessible landscaped gardens, including a large sensory garden. The apartments utilise smart home and assistive technology personalised to their lifestyle needs.A consultant was employed to review the development’s plans with regard to fire safety. His report included recommendations for additional fire safety measures including the ability for cooker hobs to be switched off by an alarm, as kitchen fires are a significant risk with 50% of all accidental house fires starting in the kitchen. WHY THE FIRECHIEF KITCHEN STOVE GUARD? The initial solution proposed was costly as it meant hob alarms would need to be hard wired into each apartment’s fuse board. Damian Pocknell, Head of Housing, Facilities & IT at the Wilberforce Trust recalled having seen and read about the Firechief Kitchen Stove Guard and realised that this would be much more cost effective. The fire consultant agreed and subsequently signed off on the Kitchen Stove Guard as the approved solution.  

Sonata Vario Class A suspended acoustic absorption panels installed within the dining room at Burlington House School to control reverberation and noise during use.

Perry Hall Academy, a large primary school built in 1949, with original waterproofing still in-situ. IKO assisted the Academy funding bid by providing a detailed survey report, including intrusive core sample analysis. The roofs were suffering from water ingress, cracks in the mastic asphalt, pooled water and poor heat retention, so decision was made to replace the roofs throughout. New rooflights were also specified to allow more natural light in while the design chosen reduced the external noise transmission. IKO worked with specifier Concept Education Services to deliver the project (some work during term-time) within 6 months.

Creating easy access to the garden is often the dream for many homeowners. Opening the space and enjoying fresh air has, thanks to programmes like Grand Designs, become ever popular. Kestrel came up with a solution for their discerning client.

The former Gaumont Palace Theatre, a grade II listed building had been given a second life to become the Ellen Terry building for Coventry University. Kestrel Aluminium together with HTL Windows and Doors took on the project to give the building a fresh look and combine the historic style with the modern touch. As the building is a remembrance from the golden age of cinema the vital part was to create an elegant run of doors which matched the original façade using modern, thermally broken commercial entrance doors.

PROJECT NAME: NORTHENDEN CUSTOMER 92 CONSTRUCTION LTD PRODUCT SUPPLIED AEROMIX SUPPLIED BY WOTMIX MANCHESTER INSTALLER CONCEPT CONSTRUCTION RIBBLE VALLEY LTD AEROMIX was chosen for this renovation project thanks to its many benefits allowing all UFH to be more cost effective and energy efficient, smoothness of finish and speed of install. Significant savings were had on this project by using AEROMIX. The customer 92 Construction Ltd complimented better U-values, a much cleaner process, no excess waste and allowed the project to complete the whole process within 1 week thus saving time and money 92 CONSTRUCTION LTD said “great progress recently over at Northenden project, with the internal sub flooring now complete, we up’d our game with this one and went for the new innovative AEROMIX liquid insulation base ground bearing slab 

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.

The original timber sleepers used for Manchester Royal Infirmary external areas had begun to rot away quite early in their lifespan. We were tasked with replicating the existing footprint of planters to replace them within the confines of the existing paving. All installation works were undertaken in a busy hospital with minimal impact on patients and workers. Using a typographical survey we created CAD outlines for each planter, a number of existing structures featured extremely tight angles, which meant we needed to modify our corner cuts to ensure a perfect match.Our components were all pre-cut ready for installation so there was no need to use any heavy machinery on site. WoodBlocX modular system is guaranteed for 15 years and because the structures are made up of a series of individual blocks, held together by strong dowels, they will not warp or distort, nor will they rot, thanks to the pressure treatment used.WoodBlocX components are manufactured in five different sizes and work in the same way as bricks, in addition, any capping and angled parts are pre-mitred, which saves installers significant build time and eliminates the need for sawing, drilling and disposing of waste. With WoodBlocX you receive a guaranteed standard of material. From the planting of the trees to harvesting of timber all the way through to cutting the WoodBlocX components, we keep on top of every aspect of each process - maintaining the highest standards of timber quality. Using WoodBlocX, specifiers can be safe in the knowledge that the supply chain of their timber products is sustainable and reliable.

There is, rightly, a continuing trend towards sustainability and sustainable design being spearheaded by forward-thinking architects and designers and building product manufacturers all keen to minimise waste in the construction industry.  Initiatives and schemes from PEFC™ and FSC® certification through to Cradle-to-Cradle design, circular economy LEED, BREEAM, and DGNB are all leaders in the fields of sustainability. This is helping drive manufacturers and specifiers to think about how they work and the products they use. One of the manufacturers which has been championing this is Danish wood wool panel manufacturer Troldtekt. Both FSC® and PEFC™ certified, the company has set strict environmental targets for its manufacture and products culminating in a transparent roadmap in its 2013 CSR report. This has led the company to be one of Europe’s most vociferous advocates for sustainable design and one which contributes positively to BREEAM, WELL, LEED and DGNB-certifications. It was recently awarded the prestigious Danish Industry Award for Green Transformation presented by HRH Crown Princess Mary.  The company’s green stance has not gone unnoticed among designers and ethical designers such as Sibley Grove which pioneer strategies that deliver sustainable interior schemes. For example, when they were appointed to re-design The Chamberlain Hotel’s public areas, sustainability was paramount. The studio’s unique approach to design assesses the environmental and social impact of every design decision, from the origin of the materials to where they end up at the end of their lifecycle. As a result, they specified as many sustainable and Cradle-to-Cradle certified materials as possible, including Troldtekt’s panels Cradle to Cradle-certified to silver level. By specifying these, the environmental impact is minimal. Troldtekt is circular and the material can go back to nature as a nutrient in the biological circuit or be included as a raw material in the production of cement in the technical circuit. By adopting a circular approach to design, Sibley Grove removes the traditional linear system of consumption and waste that plagues the design industry. It considers the entire lifecycle of a product, ensuring materials are reused or integrated back into the natural world. This reduces demand on resources, reduces landfill and encourages the production of clean, reusable materials. Troldtekt acoustic panels, manufactured from certified wood, a 100% natural material, and cement extracted from Danish mineral resources, achieve high levels of technical performance and is free of harmful substances so can therefore be returned to nature. They offer projects high sound absorption, high durability and natural breathability with low cost life cycle performance and sustainability. Available in various sizes and in four grades from extreme to coarse, the panels can be left untreated or painted in virtually any RAL colour. Samples, case studies and technical information are easily sourced from www.troldtekt.co.uk (tel 01978 664255).

Radmat has supplied a comprehensive range of systems for 20 Fenchurch Street, AKA the ‘Walkie Talkie’, in the City of London. Radmat’s PermaQuik, ParaFlex and EshaUniversal roofing membranes were installed during the creation of the Sky Garden – one of the highest green roofs in the world, offering breathtaking views over the capital.Designed by world-renowned architect Rafael Vinoly and jointly developed by Land Securities and Canary Wharf Group, 20 Fenchurch Street is constructed with impressive sustainability credentials to achieve an ‘Excellent’ BREEAM rating. The 38 storey tower incorporates a vibrant garden spanning the top three floors which is open to the public and by appointment. Described as the terraced ‘hanging gardens of modern Babylon’, the fifth-of-an-acre garden utilises drought resistant Mediterranean and South African flowers, shrubs and ferns, in soil up to a metre deep. The gardens also provide Rosemary, Thyme and other herbs to three restaurants within the building.Now London’s highest public park, the publicly accessible roof gardens include a viewing area, terrace, café, bar and restaurant. For such a unique space, it was crucial that the roofing system chosen delivered thermal performance, watertightness and long-term reliability for the client – specialisms of Radmat products. Land Securities and Canary Wharf Group awarded the work to Radmat on the basis of the company’s established reputation and expertise in all types of flat roofing.For the pitched green roofs, sectioned into a series of individual 45° slopes, EshaUniversal waterproofing was specified as part of a Radmat roofing system that included insulation and drainage layer. Made from recycled materials and 100% recyclable – EshaUniversal proved ideal to meet the demands at this sustainable development.Offering an efficient and safe installation, EshaUniversal is ideal for green roofs. More durable than elastomeric roofing, the system is also weather proof, UV stable and offers flexibility, durability and high puncture resistance making it ideal for challenging applications.Project Manager, Paul Nelson, said: “We have installed waterproofing systems over the concrete decks from ground up to second floor level then levels 34, 35, 36, 37 and 38. This required our installations teams to make repeated visits to site, using both internal and external hoists for access; with work completed in March 2014.”“The inverted roof arrangement means the waterproofing is covered by insulation and either paving, ballast or planted medium,” he added. “Then there is also the sky garden at an angle of 45 degrees planted with trees and shrubs, which will be accessible to clients using the restaurant there.”For public-access terracing across levels 34-38 – as well as a series of applications on the Ground Floor, second floor and the concrete staircase – over 1,200m² of Radmat PermaQuik PQ6100 was applied. With an independently verified durability ‘for the lifetime of the building’ and a market leading guarantee, the liquid-applied PQ6100 waterproofing system delivers exceptional performance befitting of this unique build.On level 37, where visitors can enjoy 360° views of the capital, additional waterproofing was required following the installation of a glass internal cladding system. With the glass already in place and challenged by high winds and low temperatures, the fast curing, cold applied ParaFlex waterproofing system was specified. Suitable for application at temperatures below zero reliable sealing can even be achieved at -5°C. Utilising collaborative working practices and a responsive and interactive design process, Radmat have created a stunning waterproofing and green roof application of the highest standard. Radmat’s proven range of waterproofing solutions met all the client’s demands and has ensured that visitors from all over the world can enjoy this stunning venue for many years to come.

Project descriptionDixons Academies Trust is a well-established multi-academy trust that aims to challenge educational and social disadvantage in Yorkshire and the North West.The trust transforms schools into safe and high-performing learning environments, enabling students from all backgrounds to realise their potential and maximise their opportunities after school.Alpha Roofing Systems was brought in to refurbish two roof areas at Dixons Croxteth Academy in Liverpool after the existing waterproofing failed.A number of complex challenges arose from the start; after stripping back the aged and failed single ply system, Alpha identified a water-saturated bituminous roof beneath, which also overlaid the original asphalt waterproofing.The excess weight imposed on the roof from the multiple, heavily saturated waterproofing systems led to cracking and depressions in the deck, as well as rusting of reinforcement within the structure.This meant that, before installation work could even begin, many hours of labour were required to remove the top two waterproofing layers to expose the original asphalt. What’s more, this work had to be undertaken both during term time and a period of heavy rainfall.Solution and installationAfter close consultation with their IKO business manager, Mark Taylor, the Alpha team selected the IKO ULTRA Prevent 25 waterproofing system for this project.To adhere to Department of Education requirements, a 35-year durability statement was necessary, so the long-lasting, durable finish offered by the IKO ULTRA Prevent system was ideal.Challenges continued to come thick and fast throughout the project; after stripping the roof back to the asphalt waterproofing, a large expansion joint was found near the clerestory window. Tapered designs were subsequently adjusted to accommodate.30 tonnes of waste material – primarily due to the uplift of the previous failed waterproofing systems – also had to be removed from the roof over the course of a week.Furthermore, complex design variables meant that Alpha could not fully determine the existing roof falls until the roof had been sufficiently exposed. Working closely with the IKO technical team, design information and solutions were identified to keep the project on track.To complicate matters further, Alpha was also required to carry out this extensive work during active teaching time. This presented not only additional health & safety considerations but also the need to minimise disruption.With a stringent construction phase plan and regular active monitoring, the project was completed with a zero incident/accident rate and excellent feedback from the client on Alpha’s approach to safety.Despite a number of hurdles and complexities to overcome, Alpha Roofing Systems delivered the project ahead of time and within budget, providing a low maintenance, long-lasting roof for Dixons Croxteth Academy and a satisfying outcome for all involved.

The design concept of this project focuses on the demolition of an existing building and replacing it with a new build mixed use development of 6 storeys (plus basement) 9 self-contained units on floors 1-5 and 377sq m of commercial space on the basement and ground floors. During the Phase 1 Primary Risk Assessment, borehole and trial pits revealed Dibenzo (a,h)anthracene, CO², TPH and Asbestos contamination. The proposed remedial strategy to be adopted at the site was one of managing the pathway between the source of contamination and the critical receptors on-site.
