Wokingham Hospital

Posted by Ashlea Williamson

The Phoenix Centre, nestled within the confines of Wokingham Hospital, stands as a beacon of specialised care, dedicated to administering intensive therapeutic interventions for patients dealing with complex health challenges. At the heart of the Centre’s mission lies a commitment to tailoring treatments and therapies to address the complex needs of its diverse patient base.

In light of the NHS’s concerted efforts to modernise its infrastructure and align with sustainable practices, there has been a heightened focus on updating NHS buildings across the country. This drive is not merely about refurbishing structures but also about adhering to the NHS’s proactive agenda to reduce carbon emissions and enhance energy efficiency.

In line with this ethos, Alumasc emerged as a trusted ally in the quest for sustainable solutions. Recommended by NHS Property Services North East, Alumasc was invited to lend its expertise in tackling the persistent issue of water infiltration plaguing the facility’s existing roof. This collaboration stands as a testament to the collective commitment towards ensuring that healthcare facilities not only provide exceptional care but also operate in a manner that champions environmental stewardship and sustainability.

Client Brief

The project brief encompassed a myriad of challenges that demanded meticulous attention and strategic
planning. Foremost among these challenges was the imperative need to ensure the building’s watertight integrity. Given the critical nature of the facility’s operations, safeguarding it against water ingress was paramount to maintain a safe and conducive environment for patient care.

Moreover, the project aimed to enhance the thermal efficiency of the structure, aligning with sustainability goals and optimising energy consumption. This dual focus on environmental responsibility and operational efficacy underscored the project’s significance within the broader context of healthcare infrastructure.

Compounding the complexity, the renovation and improvement works had to be seamlessly integrated into the centre’s ongoing operations, necessitating meticulous scheduling and minimal disruption to patient care routines. This multifaceted endeavour exemplified the intersection of technical expertise, operational efficiency, and patient-centric considerations inherent to healthcare infrastructure projects.

Products

After thorough discussions with the client and multiple roof surveys, it became evident that the existing roof required comprehensive refurbishment and redesign. The surveys revealed critical drainage issues, indicating improper water flow that could only be rectified through a complete overhaul of the roof’s design and the implementation of a new water drainage strategy. A series of rooflights across the 800m2 expanse showed a number of failures adding to the risk of water leakage.

In response to the client’s efficiency targets and environmental objectives, Alumasc proposed the Derbigum Olivine system as the optimal solution, which perfectly aligned with the client’s requirements.

Beyond its remarkable 40-year warranty promising longevity and durability, the system significantly mitigates CO2 emissions, playing a pivotal role in the hospitals ambition to reduce their carbon emissions.

The design of the project incorporated Alumasc roof vents, chosen for their ability to optimise airflow and address common issues like condensation build-up, moisture retention, and heat accumulation within roofing systems.

Crafted with precision and attention to detail, Alumasc roof vents seamlessly integrate with roofing membranes and other structural components. They adhere to rigorous industry standards and regulations, ensuring performance, safety, and environmental sustainability.

Beyond their technical functionality, the inclusion of rooflights serves to flood the structure with natural daylight. This feature not only enhances the architectural aesthetics but also creates a pleasant environment for patients within the centre. The infusion of natural light contributes to a welcoming and therapeutic atmosphere, promoting well-being and comfort for those using the facility.

Technical Insights

Alumasc’s innovative roofing system comprises a CO2 neutralising reinforced APP polymer modified bituminous waterproofing membrane, supplemented by underlays, insulation boards, and air and vapor control layers.

The system’s upper layer, adorned with naturally occurring minerals, catalyses a chemical reaction upon contact with rainwater, effectively neutralizing CO2 pollutants. This chemical conversion renders the runoff carbon-free as it reaches the drains, mitigating environmental impact.

Endorsed by BBA certification, Derbigum Olivine offers a fully warranted system with a life expectancy of 50 years. Despite the gradual reduction in olivine grain size with each reaction, these grains maintain efficacy for an impressive 30 years before complete depletion. Not only is the system exceptionally durable, but it also epitomizes sustainability, as the membranes utilised are entirely recyclable.

A Pioneering Solution

Detailed calculations performed by our team highlighted the numerous advantages of the Derbigum Olivine system when compared to traditional roofing methods. This environmentally aware roofing solution actively counters CO2 emissions, with 1m2 of olivine capable of neutralising approximately 1.75kg of CO2. Moreover, our analysis indicated that the current roof’s U-value fell below optimal standards, necessitating an upgrade to improve thermal performance. By installing the Derbigum Olivine system with a fully designed tapered insulation scheme, the U-value was lowered to 0.1, thereby maximising energy efficiency and reducing the centre’s operational expenses.

Challenges

The project presented a plethora of challenges, particularly as the works needed to be executed while the centre remained fully operational. The essential nature of the hospital’s services rendered any interruption untenable. Addressing the improper waterflow of the existing roof necessitated a comprehensive redesign; however, the stripping of the roof had to be conducted in phased sections. Careful planning ensued after thorough investigations to strip and redesign, ensuring the delivery and installation of correct component parts, balanced amidst the ongoing operations of the centre.

The entirety of the project stands as a testament our commitment to the NHS’s ongoing strategy to enhance patient care, underscoring its commitment to collaborative efforts with certified contractors to furnish a solution that is not only resilient to future challenges but also capable of evolving with the dynamic healthcare landscape.

Oldham Road, Manchester

Posted by Ashlea Williamson

The Oldham Road project, envisioned by the acclaimed Tim Groom Architects, stands as a testament to innovative architectural design in Manchester city centre. Comprising 144 apartments across 12 stories, this development harmoniously integrates with its surroundings, nestled amidst historic landmarks and vacant plots.

The architect conceptualised a modern ‘mill’ building, inspired by Manchester’s industrial past as ‘Cottonopolis’, paying homage to the area’s rich heritage of printing businesses. This vision aligns seamlessly with Manchester’s Neighbourhood Development Framework (NDF), enriching the urban landscape with a blend of tradition and modernity.

A key architectural feature is the bespoke large glass rooflight, strategically installed to infuse the interior spaces with natural light. The rooflight’s louvered panelling system and its proximity to the lift overrun added further complexity to the interfaces that required waterproofing. This was easily overcome by our experienced approved contractors, Primeseal Roofing. The waterproofing detailing was achieved by using a hybrid warm roof system, comprising of Hydrotech Hot Melt and Derbigum bituminous membranes.

The facade of the structure showcases individual inset balconies, while a spacious recreational terrace adorned with a green roof fosters biodiversity and tranquillity. Planters and foliage not only provide privacy and shade but also attract wildlife, contributing to Biodiversity Net Gain, a vital aspect of sustainable urban development.

To address the complexities of the project, the architect specified a combination of Alumasc’s Hydrotech Hot Melt and Caltech QC cold-applied liquid roofing solutions. Both systems boasting BBA certification, were meticulously installed by registered contractors, Primeseal Roofing, ensuring the client’s investment in a durable, futureproof roofing solution. Backed by Alumasc’s comprehensive support services, the project symbolises excellence in design and construction, setting a benchmark for urban redevelopment initiatives.

Challenges

The Alumasc Hydrotech Hot Melt system, featuring a proprietary blend of refined asphalts and synthetic rubbers with 30% recycled content, was meticulously applied to the main field area as the cornerstone waterproofing solution for the project.

Hydrotech can be utilised in a range of applications, ranging from roofing, green roofs, podium decks, and structural waterproofing, making it an ideal choice for this diverse installation. With a proven track record spanning over 50 years, Hydrotech stands as a trusted solution, backed by rigorous certification and testing protocols.

Hydrotech ensures a fully bonded, 100% seamless application to the substrate. This seamless approach significantly mitigates the risk of leaks and water ingress, thereby safeguarding the building against potential water damage over time. The durability and longevity inherent in Hydrotech offers the assurance of extended service life with minimal maintenance requirements, contributing to the sustainability and resilience of the structure.

A late stage design modification introduced a louvre screen around the rooftop plant to obscure street-level views, posing a challenge to the existing waterproofing layout. The monolithic and forgiving nature of the Hydrotech Hot Melt system facilitated the addition of 10 steel columns to accommodate the screen seamlessly. This challenge was effectively addressed by integrating pitch pockets around each post, ensuring the integrity of the waterproofing system remained uncompromised.

In summary, the Alumasc Hydrotech Hot Melt system emerged as a robust and flexible waterproofing solution, offering unparalleled protection against water intrusion while accommodating design alterations with ease and efficiency.

Intricate Detail

The intricate nature of the facade necessitated the attachment of balustrades to the upstands, resulting in
constrained spaces that demanded a secondary waterproofing layer to accommodate field sheeting and
bracketry. In response to this challenge and to ensure comprehensive waterproofing where posts intersected the field waterproofing, we utilised our Caltech QC cold-applied detailing system.

The Caltech QC high-performance roofing system features a rapid-curing, two-component, cold-applied PMMA waterproofing solution, supplemented by insulation boards and air and vapor control layers (AVCL). With a proven track record exceeding 20 years, Caltech QC undergoes rigorous certification and testing, guaranteeing reliability and durability. Its wet-on-wet application, coupled with embedded polyester fleece, yields a seamless membrane that achieves rainproof status in just 30 minutes.

This adaptable system caters to the unique requirements of each project, offering a selection of colours and optional finishes. Suitable for both refurbishment and new build roofing and waterproofing endeavours, Caltech QC demonstrates versatility across various building sectors.

The project commenced on a vacant lot situated at the intersection of Pershore Road and Edgbaston Road, right next to Edgbaston Stadium in Birmingham.

This exciting, new residential-led mixed-use development has been thoughtfully designed to offer over 370 new build-to-rent apartments, addressing the increasing demand for such accommodation in the vicinity.

The development features a variety of living spaces, including studio apartments, one, two, and three-bedroom residences, as well as ground-floor commercial spaces encompassing retail shops, food and beverage outlets, and a fitness centre.

The combination of residential units, commercial spaces, and recreational facilities will contribute to lively and engaging street-level facades, while the design ensures that most homes enjoy east, west, or south-facing aspects and access to private courtyard spaces.

Additionally, the added amenities offer job opportunities and services for the local community, complemented by a new parking layout designed for residents. Set amidst beautiful landscaping, the architecture varies in height and aims to become a prominent landmark at this well-known location. With a fibreglass model of a full size Mini commissioned for the upper terrace. This unique and unusual feature, is a nod to the historic manufacturing ties of the Mini to Birmingham.

Brief

Architects Callison RTKL UK Ltd sought the expertise and guidance of the Alumasc team to manage the expansive 4,000m2 roofing project.

It was apparent from initial design meetings that sustainability and lifecycle credentials were key to the design specification, as well as finding solutions for complex details and interface challenges.

A roofing solution was required to support the lifecycle of the building along with excellent product reputation. Given the quality, longevity, and environmental considerations required from the roofing design, the roofing system properties and warranty performance were extremely important from the outset.

Controlling Waterflow

After comprehensive discussions with the client, a combination of Alumasc’s Hydrotech and BluRoof systems were determined to be the perfect solutions for this project, both versatile systems that have a proven history across new build projects for residential, commercial, and public buildings.

By incorporating these systems within the design, Alumasc were able to offer a comprehensive and sustainable solution for water management, providing benefits that extend beyond stormwater control to encompass environmental conservation, energy efficiency, and long-term cost savings.

The Alumasc BluRoof system was incorporated throughout the design to counteract the effects of heavy rainfall. The BluRoof system is designed to alleviate flood-risk by attenuating stormwater via controlled discharge over a 24-hour period at roof level. This mitigates the effects of flash flooding and intense rainfall events, which are becoming more common as climate change is impacting on weather patterns and urbanisation is increasing.

The key feature is the ability to regulate the release of rainwater from the roof through adjustable flow control outlets, meaning it is versatile and can be used in several different applications from roofs to podiums, even combining multiple levels and larger catchment areas on roofs.

MM6125 is a special formulation of refined asphalts and synthetic rubbers with 30% recycled content.

Futureproof Design

Durability and lifecycle costing was a major consideration to the client. The installed systems are extremely durable, ensuring a longer lifespan. This longevity reduces the need for frequent maintenance and replacements, contributing to the overall sustainability of the construction.

With unrivalled third-party accreditations for life expectancy, Hydrotech was the ideal choice for this large-scale scheme. Our approved and very experienced contractor; MAC Roofing & Contracting Ltd, delivered outstanding levels of workmanship. Working in partnership in a truly collaborative approach with all stakeholders, resulted in the delivery of an impeccable solution that will stand the test of time.

With a 35-year warranty awarded on this project, the result is a high-performance, durable, roofing system which will be enjoyed by future residents for many years to come.

Our commitment to excellence and customer satisfaction is evident in our meticulous approach, ensuring a seamless experience from start to finish.

Edward Pinner Court

Posted by Ashlea Williamson

Situated in the picturesque area of Surbiton in Surrey, Edward Pinner Court is made up of 21 one bedroom and 11 studio flats. Facilities at the court include a communal room, laundry room, guest room, walkways with landscaped communal gardens maintained by residents.

The association’s Court Manager Service is an important and integral part of their approach to supporting residents. It is designed to offer support and security to those residents who need it. The service is about promoting and encouraging individuals to maintain their independence in their own home.

Brief

During routine maintenance, it was reported that some of the covered walkways linking the different areas of the site were showing signs of general wear and tear. With remedial works attempted throughout. A concern for the elderly residents. The pitched roof had several leaks and was beginning to show signs of structural issues.

Alumasc were approached to find a solution to the problem. Our technical team got to work. James Cramp Regional Technical Manager said “we used the latest technology available to us and undertook a drone survey to understand the full extent of the pitched roofing works”. We analysed the walkways to propose a solution. James adds “in addition, after a full and detailed investigation, we were able to identify that the existing pitched roof was starting to bow under the strain of the traditional heavy roof tiles. Highlighting concerns over health and safety”.

Solution

Due to Alumasc’s comprehensive portfolio, the team were able to present the client with two products working in conjunction with each other to solve the pitched roofs’ problems.

To ensure the walkways were completely waterproof, Caletch QC Balcony, with its thick, fully reinforced
waterproofing layer and a proven track record of more than 20 years, was the obvious solution.

This high-performance system comprises of a range of rapid curing two-component, cold-applied, reinforced PMMA waterproofing. Solvent free, the product is specifically designed for walkways and terraces over occupied premises. BBA Certified and available in a wide range of colours, textures and surface finishes, the team were able to fully tailor the system to meet and exceed the clients’ expectations.

To ease the structural strain on the building, the team presented Alumasc’s Airtile metal roofing system for the main roof area.

Manufactured from high quality Aluzinc Steel, Airtile Slate is extremely lightweight, in fact 7 times lighter than a traditional roof tile, this component also gives the product excellent long-lasting strength and performance, way above that of traditional materials.

100% recyclable, Alumasc Airtile is a high performing, versatile and elegant looking modern-day version of a traditional slate tile. It has all the characteristics you can expect from a traditional slate tile such as authentic finish and riven edges. However, unlike natural slate, Airtile Slate will not crack, break, chip or delaminate.

In summary, the team, together with the client, were able to select two products which solved the issues with the main roof and walkways, making them waterproof, easing the strain on the structure and providing an aesthetically pleasing and consistent look. With a 20-year warranty, the new revamped walkway can be enjoyed by the residents, plus the client can be confident in the structure for many years to come.

Challenges

As with many of our residential projects, the repairs needed to be completed with minimal disruption to the residents within the building and the surrounding area. Working closely with our approved contractor Inspire Contract Services, who undertook the works to a high level of workmanship, we were able to keep the client updated throughout every stage of the project.

Both products dramatically reduced the contractor’s installation times. Extremely quick to cure, Caletch QC can be waterproof within 30 – 40 mins per coat. Not only reducing the installation times, but it is also perfect for use in the unpredictable British weather.

As Airtile is much lighter than traditional roof tiles, installation times were reduced even further. Unlike moving heavy traditional tiles, Airtile is quick, simple, and easy to install, not only ensuring that deadlines are met, but in addition giving the client and contractors the added cost savings over the lifetime of the building.

Applied in liquid form in two or three coats, Caltech METcoat forms a seamless, durable membrane.

Caltech QC comprises of a rapid curing two-component, cold-applied, fully reinforced PMMA waterproofing solution. The wet-on-wet application with embedded polyester fleece, is quick to install and forms a seamless, durable membrane that is rainproof in just 30 minutes. Reducing installation times and keeping disruption to a minimum.

An added benefit to the Caltech range of products is that we can offer an extensive range of colours, offering a true match to any RAL/BS/NCS shade. We were able to present a wide range of colour samples to ensure the aesthetics of the roof were to the client’s approval.

The combination of these products provided the client with a weatherproof and aesthetically pleasing roofing solution, meeting and exceeding their expectations.

Challenges

Due to the sheer size of the project the main challenge was achieving successful adhesion and preparation of the damaged roof surfaces within the specified timescales. This was an important consideration as work needed to be carried out with minimal disruption to their manufacturing operations.

Our longstanding relationship with our contractor BBR Roofing Ltd, meant that our collaborative approach kept the client up to date with all aspects of the installation.

Battersea Power Station

Posted by Ashlea Williamson

Battersea Power Station is at the heart of central London’s largest visionary new development. The vast 42-acre site is a former industrial brownfield site, now the home to a community of over 250 shops, cafes, restaurants, theatre, hotel, medical centre and nineteen acres of public space, including 450 metres of river frontage and a six-acre park. The £9bn project sees the creation of a vibrant, mixed-use development including a new office district with over 3 million sq. Ft of commercial space, alongside new private and affordable homes.

Brief

The project design was divided between two architect practices, Foster and Partners and Adamson Associates. Both designs played a key part in the regeneration of zones 3A and RS4 of the Battersea site.

The redevelopment included a residential area and high street, known as The Electric Boulevard, situated south of this instantly recognisable landmark.

The goal was to create a neighbourhood that connects into the historic fabric of the city of London, but one that has its own identity. The architect’s vision was to create a humanistic environment that feels good to live and visit.

Collaboration – A Key to Success

After the completion of several successful projects across London’s iconic landmarks, including the Shard and Canary Wharf, Fosters and Partners and Adamson Associates approached the Alumasc team to provide a single source solution for the whole roofing design.

After careful planning and detailing, two complementary products from our portfolio were the perfect solution to delivering the vision. Hydrotech Hot Melt from Alumasc waterproofing system and our Extensive Green Roof would deliver imaginative design complete with durability.

During the extensive planning stage, our collaborative approach with both architectural teams and our registered contractor VolkerLaser, meant the team resolved numerous complex detailing elements across the varied roof zones. Specifically, the soft and hard landscaped podium, which was the central focus to the design.

Lifetime Performance

With zero failures in over 50 years worldwide, Hydrotech Hot Melt from Alumasc offers lifetime performance. Designed for use across all building sectors, primarily in new build construction, this unrivalled system comprises of a one-component, hot applied, fully reinforced, flexible, self-healing hot melt membrane, a range of bituminous protection sheets, insulation boards and ancillary products.

Subject to the highest levels of certification and testing. This fully warranted, BBA and European Technical Approved system is manufactured to last the lifetime of the structure to which it is applied.

Using 40% recycled content, Hydrotech Hot Melt from Alumasc is applied in a liquid state, complete with a special formulation of refined asphalts and synthetic rubbers for a 100% seamless bond. Therefore, avoiding any chance of water tracking. Its monolithic nature ensures no possibility of lap failures and is ideal for the expansive podium required at the Battersea site.

In addition to its impressive performance, the system requires little maintenance. In terms of installation, it is fast and simple to apply, especially over complex roof details like those at Battersea, so time on site is significantly reduced.

Unlike other methods, the system is extremely versatile, and not weather dependant, it can be laid at extreme temperatures (down to -18°C for winter installations).

An Environment that Considers Our Planet

The architects wanted to provide a humanistic environment that evokes a sense of wellbeing by incorporating landscaping across the roof areas.

Modernistic in its approach, our Extensive Green Roof solution is used for lightweight roof decks, inaccessible roofs, or flat and sloping roof spaces.

With stunning visual aesthetics, the introduction of roof landscaping creates a positive impact to the wellbeing of the users, encouraging social interaction as well as playing a key role in providing a positive environmental impact.

Its lightweight construction and shallow substrate, provides versatile range of planting options, comprising of succulents such as sedum, rockery, and alpine plants, which provide ecological benefits by reducing environmental impact with air purification and the reduction of CO2.

Easy to install, the Blackdown extensive green roof is different to other systems, as they do not require a permanent irrigation system. Another advantage is that general maintenance is kept to a minimum.

Darwin House

Posted by Ashlea Williamson

Located within a bustling part of Bromley, London. Darwin House is a residential cul-de-sac comprising a cluster of apartments within a short distance of Anerley and Crystal Palace.

After residents reported major leaks, which resulted in apartments being evacuated, the Alumasc team were instructed to deliver an urgent solution.

Firstly, the client instructed Alumasc to survey the roof and deliver a recommendation to solve the water ingress issue. Secondly, Alumasc were asked to suggest a suitable fixing method for a renewable energy source in the form of solar panels.

Solution

The Alumasc team identified that water was seeping into the 400m2 roof through a number of penetrations, over 95 in total. After a full investigation and consultation with the client, it was agreed that stripping the existing roof back to the deck and re-waterproofing using the Alumasc Euroroof Torch-On system would be the best solution.

Subject to the highest levels of certification and testing, the Alumasc Euroroof Torch-On system is fully adaptable to meet the requirements of this project. This proven solution is used across all types of building applications in both refurbishment and new-build.

The system is not only high performing but also extremely durable. It comes with an impressive 25-year guarantee. This assured the client that our range of products are the very best available.

During the client consultation it was also agreed that Alumasc ProSolar; a nonpenetrative photovoltaic mounting system specifically designed for mounting the proposed solar panels would be included within the specification.

The priority was to make the roof watertight again. Euroroof Torch-On with its premium torch applied reinforced APP polymer modified bituminous waterproofing membrane, underlays, insulation boards and air and vapour control layers (AVCL) solved the issues with the existing roof.

Once the structure was watertight, the team were able to install ProSolar to the newly refurbished roof. ProSolar is a non-penetrative mounting system which can be installed without the need to ballast or mechanically fix into the underlying roofing membrane. Without the need for further ballast, the system adds minimal load to the building. The framing structure consists of 92% aluminium resulting in the system being lightweight, strong and resistant to corrosion.

Challenges

The damage to the original roof was extensive. Stripping the roof back to the deck, fixing 95 penetration points, and the installation of the new system all came with different challenges. As with any residential project, time was of the essence as the residents needed to be back in their properties as soon as possible. Working in close partnership with the client and roofing contractor, the Alumasc team delivered this project in 8 weeks.

High Performance and Durability

The combination of Alumasc Euroroof Torch-on with its high performance and increased insulation properties, together with the installation of Alumasc ProSolar, means the residents of Darwin House can enjoy their homes again with the added benefit of lower energy costs for many years to come.
