Sadly, our industry lost a bright young talent on 27th August when the life of beautiful Maddie Hollamby was tragically cut short in such devastating circumstances.

Maddie was advancing her marketing career in our industry and had just been appointed Project Director of Visibility on the Travis Perkins Youth Board. A key member of the marketing team at Keyline Civils, Maddie was respected, well liked, and had her whole future ahead of her.

Tomorrow, as an industry, we are all coming together to share Maddie’s story to raise awareness for a fund that’s been set up in her memory through The Construction Youth Trust. Their work helps inspire young people to join the construction sector and our aim is to help them raise as much money as possible to continue to enable more school leavers and young people to join the industry, like Maddie did.

Donations can be made at: Donate | Construction Youth Trust

Our thoughts and prayers are with Maddie’s family, friends and colleagues tomorrow.

Client Brief and Design

Alumasc Roofing’s understanding of the client brief is evident at North Tees and Hartlepool NHS Foundation Trust who needed help towards becoming carbon neutral and more sustainable.

Maintaining NHS Trust property of roughly 28.4 million square metres whilst in constant use is no mean feat. The Trust initially tasked Alumasc Roofing with delivering a full condition report across both the University Hospital of Hartlepool and the University Hospital of North Tees.

Environmentally Focussed Solution

After intensively working together to reveal the extent of the work needed, the technical report recommended a full refurbishment roofing solution to ensure minimal disruption whilst giving maximum long-term performance. In total at North Tees, 6 large roof areas were refurbished and 3 at the Hartlepool site. This approach would prevent further damage, prevent waste from re-roof and crucially minimise disruption to the staff and patients.

Alumasc’s full range of products were installed on the refurbishment: rooflights, tapered insulation, rainwater goods, Alumasc’s Self-Adhesive Olivine membrane in a flame-free application, and Alumasc’s Caltech cold-applied liquid systems.

The cold-applied product was chosen so it could be laid safely without the need for naked flame in a very sensitive working hospital environment. Low odour liquid was selected to ensure there was no loss of comfort to staff and patients.

Sustainable Performance

The olivine felt system will save the Trust the equivalent of 44,750km travelled by car of CO2 during the life-cycle of the roof.

The roofing system is comprised of a CO2 neutralising, reinforced SBS polymer modified bituminous waterproofing membrane, underlays, insulation boards, and air and vapour control layers.

Our Self-Adhesive Olivine system not only requires a flamefree installation but is surfaced with a natural olivine granule, a magnesium iron silicate. The olivine granules initiate a chemical reaction with CO2 from rainwater which converts to silicon dioxide (sand) and magnesium carbonate, two elements harmless to the environment.

1m² of olivine has the capacity to capture approximately 1.75kg of CO₂

The Trust has a 25 Year warranty for the works and has a fire classification of BROOF (t4) in accordance with BS EN 13501-5.

Teamwork

Local Alumasc Site Technicians keep a close eye on the installation process and feed back to the client with regular progress reporting, cost reports and images. The Technicians, Installers and Surveyors worked throughout winter during the pandemic in a highly sensitive infection control environment. Additional access and PPE considerations for each area were tightly controlled.

“I’d like to give you a bit of feedback on the reports because working with a number of different roofing manufacturers I think Alumasc Roofing are certainly outshining the rest when it comes to keeping the client up to speed on how things are going. Your Surveyor communicated survey reports regularly and was always on hand to ask any technical questions and explained the processes. This level of cooperation ensures the Contractors deliver a quality install for the Trust.

The regular reports help understand the progress of each project, what is outstanding, and any issued rectified. This was vital when reporting back to my Director and the Board for budgetary purposes. Please keep this up because it certainly is working and a valuable asset to the Trust.” Glen Newby, Design and Development Manager, NTH Solutions.

Area Manager Matty Hyson adds, “delivering much needed refurbishment to the NHS is what it’s all about for the Alumasc team. Pulling together during the pandemic and achieving projects like this really makes a difference.”

Sensitively designed to keep a low profile in its exceptional surroundings, the new Conwy Culture Centre has recently opened its doors to the public.

A Blackdown extensive sedum green roof completes the low-lying, single storey centre, helping it to become part of, and give back to the natural environment.

Completed in 2019 on the site of an ex-primary school building, it is now a modern masterpiece designed to inform and entertain visitors in a beautiful, relaxing setting.

Alumasc provided a complete roofing solution which included the waterproofing and green roof system. Blackdown’s extensive sedum green roof provides a variety of planting, generally comprising drought tolerant succulents such as sedum, rockery and alpine plants. An example of an extensive green roof, it was an ideal choice for the project as it enabled its roofing element to both blend in with surroundings and positively contribute to the natural environment.

“It was important for the Culture Centre to create a serene environment that would break the barrier between nature and building,” explained Matthew Davies, Area Technical Manager at Alumasc Roofing Systems, who specified materials for the project. “Meeting the BREEAM Excellent certification standard was paramount, and the installation of a green roof was a vital step on this path.”

“The team at Blackdown Greenroofs, an Alumasc company, were extremely diligent in ensuring every effort was made to meet and even exceed the brief. The final result has the added benefit of providing a high level of insulation; another way that a green roof can help a building become more sustainable. People using the centre will find that it is cooler in the summer, warmer in the winter and overall, less energy may be used internally.”

Beneath the greenery, Derbigum high-performance membranes were also specified to ensure a completely watertight installation. The bituminous membranes can be used with a variety of insulation choices including PIR, mineral wool, and extruded polystyrene to suit specification and U-value parameters.

“We worked with 200mm of pre-bonded PIR, which provided the flexibility and easy application we needed for the project,” Matthew said. “Derbigum offers enhanced performance properties including excellent flexibility, fire ratings, strong reinforcement and ease of application, so it’s an extremely popular choice. Critically though, they have a 40-year BBA durability approval with use at zero-falls.”

Throughout the design and construction stages Alumasc Roofing Systems worked closely with DarntonB3 Architecture, the Project Architect. “We were extremely pleased with the workmanship and overall installation of the waterproofing and green roof systems” commented the Project Architect.

Along the duration of the project, the Alumasc team paid the Centre a visit, to assist with the project’s design. “We were able to provide a cost-effective solution, whilst delivering excellent insulation standards by Alumasc,” Matthew says. Although the overall project ran smoothly throughout its building phase, Conwy Culture Centre project did come with some challenges. “The weather was our biggest obstacle,” Matthew revealed, “which slightly delayed the installation of the new roofing system.”

Located in the corner of Bodlondeb Park, North Wales, Conwy Culture Centre is of walking distance from Conwy’s sumptuous medieval town. This light and airy building houses a brand-new county archive, library area, heritage exhibitions, café and community arts hub and the exhibitions on display take visitors through five thousand years of history. The Culture Centre is also dementia friendly. This comes as a result of the landscaped areas around the centre which include a peaceful sensory garden with dementia-friendly and accessible paths and seating and a carefully considered interior.

This Bodlondeb Park land was a gift from Albert Wood, whose family had made their fortune from manufacturing ships’ anchors and cables. The £2.5 million Culture Centre has stunning views towards Conwy Castle and has been constructed to the BREEAM Excellent standard, meeting the standard for best practice in sustainable building design.

The University of East Anglia (UEA), Norfolk, has recently benefited from a £19 million refurbishment project which saw specialised rooftop machinery safely supported by Roof-Pro support systems.

Purpose-built as the university’s new science building, Building 60, was officially opened at the university in October 2019.

The brand new 6000m² state-of-the-art teaching facility is situated at the western end of the University of East Anglia campus, which resides within 230 hectares of land in Norwich Research Park.

Roof-Pro, an Alumasc company, provided specialised pivoting supports around three Daikin Chillers, air conditioning units, and two VES AHU units, energy saving heat recovery units, that sit on the roof of Building 60. These supports are designed to provide stability and balanced weight distribution across the roof area for the utmost safety and no roof damage.

The roof finish, wind-load, space constraints and future maintenance requirements were all taken into account when producing this bespoke Roof-Pro support system for the project.

“One of the many reasons Roof-Pro was specified on the project was the appealing 20-year warranty which is available for all Roof-Pro bespoke systems,” explained Jimi Ogunsola, Regional Technical Manager for the project. “It’s a highly trusted system that’s well known in the industry.”

“Roof-Pro supports are a safe and efficient way to quickly access and allow maintenance to important systems situated on the roof, whilst avoiding penetrating or damaging the roof’s membrane.”

The campus’ busy activity required the Roof-Pro team to be extremely efficient, with only two weeks to design, manufacture and deliver the frames in order to meet the deadline.

“The contractors were very pleased to see our products arriving already partly assembled, with all mounting plates pre-drilled, which saved them much labour time on site. Installing Roof-Pro’s support system is very easy, therefore great to work with within a tight time limit,” said Jimi.

“This logistically challenging site required our team to coordinate daily with the UEA Estates Department,” said James Mitchel, Main Contractor at RG Carter, who worked on the project, “as well as the nearby Norfolk and Norwich University Hospital and other campus users to ensure construction activities did not disrupt routine.”

As part of a range that can be tailored bespoke to a client’s needs, Roof-Pro’s large unit support solutions are able to meet the requirements of many various sizes and weights of building service units, as well as specific roof designs and site parameters.

Building 60 provides the university with a comprehensive range of high‑specification lecture and seminar rooms for students across all disciplines. Its top three floors comprise teaching laboratories, with the ground floor maintaining an open interactive space for over 500 students.

Aiming to provide students, professors and associates with a multi-faceted space for many faculties, it features laboratories and social learning spaces where both traditional study and creative interaction are able to grow side by side. The idea informing the entire building design originates from the campus’ ideology of collaboration and discovery.

The buildings bespoke laboratories include large numbers of data connections, sensory lighting and localised fume extraction systems which allow students to carry out advanced experiments under controlled conditions.

East London’s Whitechapel Station, which will eventually become one of the stations on Crossrail’s brand new Elizabeth Line, has taken advantage of its canopy roof area and transformed it into a valuable environmental asset.

An extensive sedum NatureMat^® green roof from Blackdown Greenroofs, an Alumasc company, was specified and installed at the station. This came as a result of the horticultural partnership between the Transport for London network and Kalzip Standing Seam Roofing Systems, which has been a partner company of Blackdown since 1999.

Being experts in the green roof field, Blackdown were able to effectively recommend the most appropriate green roof system to be installed over the Kalzip standing seam roof.

NatureMat® is part of Blackdown’s extensive green roof range. It is lightweight with a relatively shallow substrate, however, still offers a wide range of planting possibilities, including drought tolerant succulents such as sedum, rockery and alpine plants. Blackdown extensive green roofs provide a wealth of ecological and economic benefits such as reduced water run-off and increased biodiversity.

The £50,000 project was completed in November 2019, installed by contractors BBMV, a partnership between Balfour Beatty, Bemo Tunnelling, Morgan Sindall, and Vinci Construction.

BBMV Section Engineer Nasi Payman, who worked on the project explained: “This project involved a lot of coordination with other services and trades due to the restricted access, location above a rail track, and the fact that it is a prestigious project.”

One of the main challenges with this project was that the station roof was curved from 0 to 22 degrees, which meant the green roof system had to be specially designed to function on a unique sloping surface. A specialised NatureMat® system was specified as it incorporated a 25mm fully wrapped drainage layer, a 50mm substrate and a 25mm sedum mat. 

“As the roof pitches at 22 degrees it required a high degree of planning and meticulous attention to detail throughout planning and installation,” explained Nasi. “Moreover, the pitched areas required the addition of substrate retention battens to stop the migration of the materials down the slope.”

“Blackdown are known for offering high quality installations on sites that demand a high degree of management and safety input. We were delighted to work with them on this really interesting and innovative project.” said Nasi.

“We are delighted with the very successful outcome, which delivered an addition to the scheme that will have both aesthetic and environmental benefits for anyone using the Crossrail facility,” concluded Nasi.

Alumasc Derbigum Olivine roofing absorbs and neutralises CO₂ on contact, as it falls in rainwater. This ground-breaking technology has been used in the recent redesign and refurbishment of Nottingham Trent University’s Clifton Campus Library, which now features over 1000m² of Olivine, providing a waterproof, BBA approved roofing solution.

As one of the UKs most environmentally friendly universities, NTU has a reputation to uphold. The UK market for green construction projects has grown significantly in the last 10 years and is poised to grow further in the next three. As society’s collective environmental conscience grows more aware, developments which design with environmental concerns in mind have become more revered. This seems to be the case increasingly so with students and younger generations.

As well as teaching the effects of positive actions towards the environment, NTU has decided that the best way to impress the importance of their students is to demonstrate it in their campus buildings.

M & J Roofing installed the membranes, after it was identified as the most appropriate waterproofing solution that would also offer the sought after added environmental benefits. As a bituminous felt system, Derbigum Olivine is 40% recycled, therefore from an environmental point of view, it has an edge over many competitor brands.

“Alumasc Derbigum Olivine roofing contains a naturally occurring mineral upper layer that irreversibly neutralises CO₂ that falls in rainwater, on contact,” explains Ben Green, Divisional Marketing Manager for Alumasc WMS and Alumasc Roofing. “When the rainwater rolls off the roof and eventually reaches the drains, it’s carbon-free. The olivine grains decrease in size with each reaction, however are large enough to last 30 years plus before having completely reacted. It’s construction industry science at its finest!

“The membrane itself is guaranteed for 40 years, carrying the longest British Board of Agrément (BBA) certificate in the UK. It’s high melting point ensures membrane stability in the hottest weather whilst the polyester/glass fibre reinforcement provides high tensile strength.”

This refurbishment also included the specification of Alumasc Rooflights and Harmer aluminium Roof Outlets, coupled with GX Pressed Aluminium Gutters and Heritage Circular Pipes, ensuring adequate drainage could be achieved for the new roof.

Alumasc Rooflights provided an ideal solution to allowing natural daylight into the building from above. The unique kerb design incorporates both security and waterproofing to create a reliable, safe and secure rooflight, allowing horizontal termination of the waterproof membrane. This makes water penetration virtually impossible. The domed glazing is moulded from Marlon FSX Longlife, premium quality solid polycarbonate, which has an impact resistance up to 200 times that of glass.

Technically sophisticated, Harmer AV high-performance aluminium roof outlets are chosen for this project as they guarantee a trouble-free performance and are especially suited to flat roofing applications featuring continuous membranes.

Harmer AV roof outlets combine innovative product design with full industry compliance to meet the needs of rainwater drainage in any construction project, with the ability to drain up to 40% more roof area than conventional gravity outlets. Further to this, their lightweight, durable, non-corrodible design means that they will do so for up to 40 years.

GX Pressed Aluminium Gutters are robust box section gutters designed for traditional wet jointing on site. They’re especially suited to applications where maximum capacity gutters are required. For the very large drainage area of the campus roof, they were perfect.

Designed to fully accommodate thermal movement at every joint, they are lightweight, durable and noncorrodible, and, upholding the environmental prerequisites of this project, they are 100% recyclable.

Finally, Heritage Circular Pipes are available in 4 pipe diameters and 3 pipe lengths, together with a complete range of fittings. Can be factory finished to replicate cast iron or with BBA certificated powder coatings in a range of colours.

Boasting iconic views over the River Thames, taking in the London Eye, Big Ben, and the iconic Houses of Parliament, Waterloo’s shining Whitehouse Apartments are iconic in their own right.

Standing fourteen stories tall among the Southbank’s cultural swathe, the impressive, polished residential buildings, have recently been completed with state-of-the-art Alumasc Derbigum roofing.

Craig La-Thangue, Senior Contracts Manager at Acclaim Contracts, who installed the roof, explained, “Our project at the Whitehouse Apartments was very enjoyable to complete, for many reasons, including the spectacular view, and of course working with Alumasc Derbigum membranes, as the high-quality product made the project run very smooth.”

Over the entire 2200m² roof area, Craig and his team first removed the old roofing that was in place—which just so happened to also be an Alumasc product!

“When we got up there, we were surprised to find that the roof that was in place was actually still in good condition,” Craig explained. “It had been up there for 30 years, but the only places that were showing serious signs of wear were the patches around installations such as air conditioning units and skylights that had been installed after the roof was laid.

“These roofing membrane patches were from another brand, which hadn’t fared well at all, and had visibly deteriorated to the point where they were letting in water.

“Over time, this would cause damage within the building that could lead to other more serious problems further down the line, so it was important for us to replace the roof and do a good job.” 

Derbigum is a high-performance waterproofing membrane that carries a BBA certificate confirming its service life in excess of 40 years. It offers performance properties including excellent flexibility, fire ratings, strong reinforcement and ease of application.

Derbigum is ideal for warm roof applications; its high melting point ensures it will remain stable even in the hottest weather. Alongside this, the polyester/glass fibre reinforcement within the membranes provide high tensile strength.

Giving specifiers and contractors peace of mind, Alumasc Derbigum membranes are manufactured in accordance with ISO 9001:2015 and ISO 14001:2015.

The project ran smooth from start to finish, from December 2018, to April 2019: “The only obstacle was the sheer size of the project!” commented Craig.

“Working with Alumasc is always hitch-free. We have worked with them on a number of other projects and they always have been reliable. Even if there is an issue, it’s sorted out quickly, efficiently and professionally. It makes us feel very confident in both the company and the roofing products,” Craig concluded.

Roof-Pro’s PP-3 riser penetration units have been used to provide watertight pipe and cable entry points into the building at Tonyrefail School near Cardiff, South Wales.

As part of a project worth £44 million, the school was delivered under the auspices of the Welsh government’s 21st century schools programme. It’s one of a number of ‘super school’ education projects to be delivered in Wales as part of an initiative to improve education in local areas, and all have to be delivered within a tight timescale to meet the target.

After discovering Roof-Pro, an Alumasc company, online and finding many positive reviews of similar work, Boyes Rees Architects chose to specify Roof-Pro roof service entry units as they are capable of dealing with larger circular duct sizes of 600mm and above, whilst still remaining watertight.

The PP-3 puts the waterproofing’s durability first in its design – for quick installation into the waterproofing membrane. Its design also encompasses easy access features, a powder coated aluminium finish for durability and cover flashing deep enough to permit vertical insulation.

Roof-Pro were also able to accommodate the client’s tight timescale and conducted the site visit, issued drawings for approval and delivered all products to site on time.

Roof-Pro’s Regional Technical Manager Jimi Ogunsola, who worked with Boyes Rees Architects to find the right product for the project, explained: “The Roof-Pro PP-3 access riser was perfect for this project, providing a watertight entry point to run larger roof-mounted cables, ducts and pipes into your building safely—a consistent, quality solution for necessary penetrative details on flat roofs.

“The design allows M&E trades easy access to run cables and pipes. Once installed, the building is immediately dry, and following trades can fully access the riser by temporarily removing the lid.”

Mark Harries of Whitehead Building Services, the contractor who worked on the project said: “Alumasc were a pleasure to work with for this project; communication was extremely important given the fast approaching deadline but all went smoothly.

“Even when we found ductwork and capping that had been installed already were not sufficiently watertight, airtight nor adequately insulated, we were able to communicate effectively and put plans in place to ensure that the extra work would not disrupt the timescale.”  

Mark went on to say: “We found Roof-Pro products very durable, and easy to install. They provide great value for money by offering a second-to-none watertight seal and excellent quality, which just can’t be substituted.”

A place that seeks to find the perfect balance between work and play, The Old Vinyl Factory is home to a large, young community and provides them with commercial and leisure facilities, restaurants, shops, cafes and bars.

But this isn’t all. Far above the ground, a series of roof gardens and patios have also been sensitively developed by Blackdown Greenroofs, catering to the large number of young families and working parents in the community.

The four main blocks rise above a central podium area, hiding their private oasis from the general public, making them a haven of calm and tranquillity that extend the idea of living space to the outdoors.

Landscaped to provide opportunities for relaxation as well as play areas for children, small trees and shrubs provide the gardens privacy, while playground apparatus complete the area.

Having a recreational green area is a huge and often rare benefit to urban and city dwellers, who may not have access to nearby public parks or natural areas. Research has shown that those who regularly spend time in a natural environment have improved mental, physical and even emotional health.

The gardens also replace most of the green space that may have otherwise occupied the space where The Old Vinyl Factory buildings sit, encouraging local natural wildlife and aiding biodiversity.

To achieve this, Blackdown Greenroofs installed an intensive green roof with integrated bespoke intensive planters containing a variety of wildflowers, sedums and shrubs, alongside some paved areas, benches and decking. An intensive green roof features a substrate of increased depth, so that planting can be similar to that on the ground: planters, lawns, trees and shrubs all have a healthy home here.

Rob Beswick at B D Landscape Architects, who designed the space, said: “I have been really impressed with the completed development. The podium landscape and roof terraces are well installed and it’s great to see a project where the quality of the soft landscape hasn’t been compromised.”

The children’s play area includes large pebble seats, bears, large 3D resin play models and active play equipment. Permanent irrigation systems are installed to ensure the gardens’ longevity and that this area in particular doesn’t flood.

With providing the utmost health and safety in mind, gates and fencing were also installed, all using specialist fixing methods to ensure the integrity of the waterproofing membrane below the green roof was not compromised.

One of the busiest buildings at the University of Dundee was able to benefit from a complete replacement of its waterproof roofing with Alumasc Derbigum Olivine roofing membranes.

The August 2018 project ran for six weeks and was completed on time, without any complications, after a thorough site survey to correctly identify the project needs.

During the survey, it was discovered that the roofing in place had exceeded its lifetime, and was in very poor condition.

After receiving specifications from Alumasc, the client decided to take the opportunity to install a high-quality roofing solution that would also contribute positively to the environment.

“Olivine membranes are extremely special,” explained Permatop Roofing Director Jim McVeagh, who headed up the project. “Olivine is a highly effective, durable waterproofing solution for roofs which also actively purifies the air by neutralising CO₂ in rainwater.”

Olivine membranes use a naturally occurring mineral upper layer that neutralises the most prevalent greenhouse gas via an irreversible chemical reaction when it comes into contact with rainfall. This technology was developed with the objective of contributing positively to the on-going challenge that climate change poses.

The Olivine grains within the membrane decrease in size with each reaction, however, once installed, clients can rest assured that they’ll continue to work for up to 30 years before the grains will have completely reacted. Each membrane is 100% recyclable and British Board of Agrément (BBA) approved.

1kg of Olivine granules have the capacity to neutralise 1.25kg of CO₂, meaning over its 30-year life time, this 600m2 project could potentially absorb nearly 3500kg of CO₂.

Alumasc Derbigum Olivine roofing is ideal for warm roof applications. It’s high melting point ensures membrane stability in the hottest weather whilst the polyester/glass fibre reinforcement provides high tensile strength. In the middle of the summer, this was an extremely important consideration for Jim.

“Personally, I think the technology that goes into Olivine is amazing,” Jim commented. “Anyone who chooses to install Olivine on their rooftop is actually doing something positive for the environment, while also ensuring a high quality, built-to-last waterproof solution for their roof. It couldn’t be easier, so why not?”

Approved by the BBA (Certificate No 86/1593), all Derbigum roofing membranes, including underlays and vapour barriers, are CE marked, with Declaration of Performance (DoP) certificates available.

Alumasc Roofing carefully carry out site surveys, and offer specifications, CAD/BIM calculations and designs, site reports and monitoring and roof maintenance to ensure that each and every project is executed and maintained to the highest standard.

Permatop Roofing are an approved contractor to install Alumasc products, and won the tender for this project based on their experience and expertise in this type of refurbishment work.

“Permatop will only work with the best quality roofing products,” said Jim, “which is one of the reasons why we work with Alumasc: the products are of excellent quality, great to work with, and the company is overall very reliable.”
