The impressive 20,000m² facility, designed by Todd Architects, is set around an inner courtyard and roof garden. 4,000m² of Hydrotech was installed on the concrete podium of the courtyard which is situated above a basement car park.

Landscape architects, Paul Hogarth, specified Hydrotech as part of the green roof package as it can be installed with zero falls, thereby keeping podium height as low as possible. Combined with Hydrogard protection layers and root barriers, Hydrotech offered the ideal waterproofing solution for use beneath Alumasc’s ZinCo Intensive Green Roof.

ZinCo Intensive Green Roof systems enable virtually any type of ‘garden’ landscape to be created and the deep substrate can support a range of plants, trees and shrubs. The College courtyard, where the ZinCo system was installed, offers the benefits of a small urban park, providing a welcome habitat for wildlife as well as additional recreational space for the students.

At Belfast College, Hydrotech impressed main contractor, Patton, who approved its use following a demonstration of its benefits at Alumasc’s headquarters.  Roofing Contractors on the scheme were Willart Roofing, who received full training from Alumasc to ensure a successful installation.

Alumasc’s Hydrotech waterproofing and ZinCo green roof systems have played a key role in creating high quality new homes and leisure spaces at Kidbrooke Village in London SE3.

The regeneration project by Berkeley, meets Code 3 for Sustainable Homes and provides for approximately 4,000 private and affordable homes, surrounded by open space, shops, community facilities and an improved transport system.

The specified systems met a strict list of criteria from Berkeley who required a BBA accredited structural waterproofing solution that could be laid to zero falls and would last the lifetime of the scheme. Hydrotech proved ideal for this project as its monolithic nature enabled its use in the phased construction and allowed quick installation.

The first apartments in Phase 1, City point, are now complete, incorporating Hydrotech and ZinCo systems on the podium areas, private balconies, terraces and main roof areas. The roofing specification included Hydrotech inverted waterproofing systems with Hydrogard 20 for the hard landscaped areas and Hydrogard 40 Anti-Root for the soft landscaped areas. The ZinCo intensive and semi-intensive green roofing areas contain growing substrate and appropriate planting.

In total, Tilbury Contracts will install over 12,000m² of Alumasc waterproofing across a total of seven blocks. Tilbury, who were already prequalified to work with Berkeley, put together a highly experienced and trained team of installers who brought Phase 1 of the project to a successful conclusion.

The roof itself covers over 17,000m² – the equivalent of 2.5 football pitches – and required over 16,000m² of Derbigum Rapido.

The sustainable roofing solution roof helped to secure planning permission for the Peacehaven facility, following a decade of delays, by convincing planners of its ability to marry perfectly with the surrounding countryside.

The Derbigum Rapido waterproofing system was a vital element of the green roof and one of the main contributors to the success of the project. The roofing solution was developed by Alumasc and their approved contractor, Prater Ltd who installed over 16,000m² of Derbigum Rapido over the HPS200 coated metal deck single ply structure.

Derbigum waterproofing systems combine durability with the speed and ease of installation of a single layer system. Options are available for completely flame-free, high speed spray installation (in excess of 800m² per day) which is BBA approved and fully warranted.

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 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.

Designed by architects Lovell Ozanne and Partners, the Hougue a La Perre housing development is situated on the northern outskirts of St Peter Port and is managed by Guernsey Housing Association. The project entails the development of 77 houses and flats constructed in 2009 on the site of the former Grand Bouet bus depot in order to create a sustainable and attractive neighbourhood.

The ZinCo green roof from Alumasc was specified for the podium deck above an underground car-park, which forms a courtyard for use by the residents. The green roof will offer notable ecological and amenity benefits, providing a natural habitat for plants and wildlife, whilst also helping to reduce air and noise pollution, cutting carbon emissions and assisting with rainwater retention and attenuation.
