Hydrotech MM6125 Structural Waterproofing from Alumasc, has been used on the new Sainsbury Laboratory, overcoming numerous challenges presented by the roof’s unusual design.

The award-winning scheme, designed by architects Stanton Williams is an 11,000m2 plant science research centre set in the University of Cambridge Botanic Garden. The concrete roof deck features a range of complex details such as photovoltaic panels, roof lights, exposed roof edge details and sunken wells housing mechanical and electrical services.

Alumasc’s Approved Contractor Fenland Flat Roofing installed 6000m2 of Hydrotech MM6125 structural waterproofing over the concrete roof deck during a six-month period which took them through the winter of 2010/11. The Hydrotech system was chosen for its high performance bituminous rubber blend which allows fast and simple installation over complex roof details and around penetrations.

The building’s environmental features also tested the skill of the installers. Pebbles were used as ballast around the photovoltaic cells, whilst paving slabs have been used as walkways to provide access to the sunken wells which are designed to hide the M&E services below the roofline.

The project has won several major awards including 2011 World Learning Building of the Year WAF Award; the 2011 Concrete Society Award and was highly commended in the Major Project category of the British Construction Industry Awards. It has also been awarded a BREEAM “excellent” rating for its outstanding environmental performance.

Manufactured using 10% post-consumer recycled material, Hydrotech’s unique formulation guarantees lifetime performance.  Hydrotech is fully warranted, BBA Accredited and has European Technical Approval ETA-05/0152.

 A Derbigum warm roof system from Alumasc has been used in the roof refurbishment of Doddington Community Hospital in Cambridgeshire – a project requiring complex liaison between the contractors who were working around the demands of one of Europe’s largest ever temporary roofs throughout the installation.

The hospital roof had come to the end of its lifecycle and urgently needed replacing.  Following the consideration of a number of options, the client,  NHS Cambridgeshire, decided the entire roof should be replaced.

The versatility of Alumasc’s Derbigum system was a major contributor to the work being finished on schedule, despite the scale of the project and the complicated logistics.

The main contractor, Morgan Sindall, was asked to remove the existing waterproofing and deck and install a new plywood deck. Alumasc approved contractor, Camflat Roofing, installed 1700m2 of the Derbigum warm roof system with a mineral surfaced Derbigum cap sheet, carrying a 20 year warranty. The system comprised a 4mm thick dual reinforced Derbigum membrane based on APP modified bitumen with a decorative mineral weathering surface, offering a combination of high performance protection plus speed and convenience of installation.

A huge HAKI temporary roof was used on the project to prevent any possibility of water ingress into the hospital while the roof was being replaced, enabling it to stay open to patients. Even though the temporary roof was one of the largest ever erected in Europe, it still only covered half of the space being re-roofed. All work in progress had to take place under the covered section which was moved on rails to the other end of the roof half way through the job. The work also included detailing around new windows, roof lights, and plant and courtyard areas.

Mick Smith of Camflat Roofing comments: “This job was complex in terms of the logistics and working under the temporary roof. Alumasc’s advice and support during the project was highly valuable and the speed and versatility of Derbigum was also a major factor in successfully completing the job.”

Derbigum warm roof systems combine the proven durability of the Derbigum range, with the speed and ease of installation of a single ply system. Options are available for completely flame-free, high speed spray installation (in excess of 1000m2 per day) which is BBA accredited and fully warranted.

Hydrotech Rises To Titanic Challenge

Posted by david.luukas

Titanic Signature Building | Alumasc Hydrotech

Hydrotech MM6125 Structural Waterproofing from Alumasc has been used on the Titanic Belfast Building – the world’s largest Titanic visitor attraction.

Specified in favour of four competing systems, Hydrotech offered an innovative and practical waterproofing solution for the intricately shaped podium roof on Titanic Belfast, created by Civic Arts/Eric R. Kuhne & Associates and Todd Architects. The distinctive design of the building and surrounding podium roof, situated above an underground car park, presented a number of challenges to Alumasc and their Approved Installer Grainger Roofing which demanded a unique configuration of waterproofing system and expansion joint.

At specification stage, Alumasc demonstrated to the construction and design team how the waterproofing and expansion joint would work together to accommodate the changes of direction and elevation presented by the podium expansion gap.

Hydrotech is the ideal solution for podiums and highly detailed waterproofing schemes such as Titanic Belfast. The high performance bituminous rubber blend allows fast and simple installation at low temperatures, even over complex roof details. The robust system enables details such as up stands to be completed first allowing other trades to proceed. Highly site trafficked areas can be left until last to avoid the need for protection or the possibility of damage.

Opening in March 2012, the 14,000m2 Titanic Belfast building tells the story of RMS Titanic, and houses Northern Ireland’s largest dedicated banqueting facility. The project, built by Harcourt Construction (NI) Ltd, is jointly funded by the Northern Ireland Executive, Belfast City Council, Belfast Harbour and Titanic Quarter Ltd.

Derbigum to the Rescue at Boss House

Posted by david.luukas

Alumasc’s Derbigum Waterproofing system has played a key role in vital refurbishment work carried out on a prestigious London residential scheme.

Boss House is an upmarket warehouse conversion situated in the Shad Thames District of London. The existing 14-year-old roof urgently needed a complete upgrade, requiring Alumasc to work closely with Lamberts Chartered Surveyors to provide an innovative solution which would avoid the displacement of residents for the duration of the works. Whilst conventional approaches such as temporary roofing would have been prohibitively expensive and highly inconvenient for residents, Alumasc rose to the challenge, providing a competitively priced solution enabling everyone to remain in the building throughout.

The proposal involved attaching a new plywood base to the existing standing seam roof using timber packers fixed into the metal structural purlins. Working with the installer Tower Asphalt Ltd, Alumasc carried out tests on the roof to ascertain the correct fixings and to confirm that it would be possible to carry out work with residents still inside the premises. Tower Asphalt installed 1600m2 of 4mm Derbigum Mineral Charcoal, and throughout the project Alumasc liaised closely with the building surveyor, to ensure a smooth operation resulting in work being completed ahead of schedule.

Designed for situations requiring high performance and time efficiency, Derbigum Waterproofing was the ideal solution for Boss House, applying the proven durability of Derbigum with speed and ease of installation. Options are available for completely flame-free, high speed spray installation (in excess of 1000sq.m per day) which is BBA approved and fully warranted. The system is suitable for use on warm roofs with metal, concrete or plywood decks, both for re-roofing or new build applications.

Alumasc has provided a stunning ZinCo green roof for Coworth Park Hotel Spa, the ‘ground breaking’ new eco-luxury spa opened by the Dorchester Collection.

The luxurious spa is situated in Ascot on the borders of Windsor Great Park, buried within the natural contours of the landscape. The building is camouflaged by the ZinCo green roof which is also being used to cultivate thyme, lavender, chamomile and other fragrant herbs for use in natural treatments at the Spa. The pioneering design by architects, Purcell Miller Tritton, has kept the building’s volume and footprint to a minimum whilst intimately relating the spa to its sensitive green belt setting.

Throughout the design and installation, Alumasc liaised closely with Purcell Miller Tritton to find the optimum solution for the unique semi circular design of the Spa’s pitched curved roof.  A total of 700m² of extensive and semi-intensive green roof systems were installed by M&J Flat Roofing over a Derbigum Warm Roof waterproofing system, also from Alumasc.

Alumasc have donated  their Firestone RubberGard® EPDM single ply roofing system to Balsall Heath Church Centre in Birmingham as part of a unique refurbishment project.

The Church’s new roof represents the UK’s very first use of  an innovative Photovoltaic System from Advanced Green Technologies (AGT) with Firestone RubberGard® EPDM.

Rubbergard® provides outstanding performance at extremes of both hot and cold temperatures, making it AGT’s system of choice for use with AGT Flexlight solar panels.

Installation of the roof was carried out by Close Building Services of Doncaster and Birmingham, a Firestone Approved Installer who worked closely alongside Jericho Construction for the duration of the project.

Reverend Catherine Grylls of Balsall Heath Church Centre comments, “We are delighted with all the help given to allow this project to go forward. The Centre hopes to be a beacon of environmental sustainability. We will earn useful income for supplying clean electricity which will help to fund our work with local elders and we are delighted that this project will also benefit local unemployed young people through our partnership with the Jericho Foundation. For us as Christians it is vital that we try to live well with creation, locally and globally, and so environmental sustainability and addressing inequality are key issues for us.”

Green roofs have been increasingly heralded as solutions to many of the challenges that face the UK’s built environment in today’s climate. Recent urban regeneration has led to increased population densities in the UK’s major towns and cities and the associated reduction in soft landscaped areas has created design issues that require sustainable solutions.

Green roofs can counter many of these threats, however, a lack of credible independent reference literature that is specific to the design and installation of green roofs in the UK, has surely restricted the number of installations across the country.

Alumasc has been heavily involved, with a number of fellow contributors, in the development of the GRO Green Roof Code of Best Practise for the UK 2011.

The Green Roof Organisation (GRO) as a body is facilitated by the National Federation of Roofing Contractors (NFRC). The code is a clear concise guide that aims to:

1. Provide specifiers and installers with the requisite understanding of the key issues that affect the design, installation and maintenance of high quality, flourishing green roofs for the long-term;

2. Highlight the implications of different green roof specifications;

3. Standardise and clarify the terminology used to describe green roof issues and components through the publication of definitions for key terms;

4. Enable specifiers to comparatively assess the different manufacturers’ systems through the provision of guidance as to the function and relevant performance characteristics of each component within the build-up;

5. Guarantee a minimum quality standard for systems that comply with the requirements of the Code;

6. Promote the benefits of green roofs and highlight how different green roof build-ups can be tailored to prioritise specific objectives;

7. Highlight important health and safety issues that must be observed at the early design stages of a project;

8. Encourage green roof installers to undergo specialist, structured training courses to gain the expertise that will underpin greater numbers of quality green roof installations;

9. Provide for the long-term success of green roof installations by encouraging entry into maintenance contracts with the installing contractor;

10. Provide a foundation upon which further iterative developments can, in time, be based; leading to green roof guidelines that are as comprehensive as any available, including the publication of standard procedures for the characterisation of components and of required performance levels, so as to underpin the continuous improvement of green roofs in the UK.

Newbuild Sector Turns To Hydrotech

Posted by david.luukas

Roof detail at Petchey Academy

With environmental considerations being more commonly incorporated into design specifications for contemporary roofing, our Technical Development Manager Chris Lister explains the increase in the use of our Hydrotech MM6125 Structural Waterproofing system in the Newbuild sector:

Chris comments, “The onus is on modern roofs to provide more than just traditional protection from rainwater. In addition to accommodating familiar performance features such as plant rooms and air conditioning systems, the introduction of green roofs and photovoltaics is now presenting the need for more specialist detail.

“Hot melt systems such as Hydrotech, provide a seamless waterproofing membrane ideal for green roofs and podiums and for highly detailed waterproofing or water feature schemes. The system moulds itself around intricate detailing on high performance roofs and is also the first choice for zero falls waterproofing on inverted green roofs and hard landscaped podium structures in new build applications.

“Due to the recent economic situation, contractors are also increasingly conscious of project deadlines and budgets. Hot melt systems allow fast and simple installation over complex roof details, which in many cases can assist in the timely completion of projects and the avoidance of contractual penalties. For example, Hydrotech was recently chosen to provide a fastrack waterproofing and inverted roofing system to the 2600m² roof at the new Petchey Academy in Hackney. Separate plant areas and a 400m² terrace were completed early, together with 1300mm high waterproofed and insulated perimeter upstands, enabling the efficient installation of associated glazing and cladding to ensure that tight contractor deadlines were met successfully.”
