An exclusive new housing development in the heart of London is the latest showcase for a range of waterproofing and green roof solutions from Alumasc.

Built by The Berkeley Group in the centre of Belgravia, the elite Ebury Square development offers a selection of one to four bedroom private residences.

Alumasc’s Registered Contractor Tilbury Contracts Ltd, installed a total of 3,800m² of Hydrotech monolithic membrane to the lightwell areas, podium roofs, individual balconies, wraparound terraces and penthouse balconies, which were all completed as inverted roof designs.  A Hydrotech anti-root waterproofing system, inverted roof insulation, drainage boards, extensive green roof substrates and sedum mats were also installed to the main roof areas. The courtyard was waterproofed and insulated and a drainage board installed providing support for the construction of deep planters, raised areas and stairways creating attractive landscaped gardens and protection for the car park below.

The project presented a major challenge in that it is situated directly over a London Underground route. The concrete slab at ground level was mounted on large anti-vibration springs, and isolated from the surrounding construction to prevent damage to the building from the vibration of trains below.  The resulting 50mm joint between the isolated and non-isolated structures, required appropriate waterproofing to prevent water entry into the basement below.

Working together, Alumasc and Tilbury Contracts strapped the joint using FlexFlash UN, an uncured neoprene rubber, with the full Hydrotech 6125 system abutting the joint edge on both sides to ensure it was watertight whilst also keeping the two slabs isolated. A brick upstand was built directly off the Hydrotech, and the full system was dressed from the previously waterproofed horizontal slab and up the face of the brickwork, and terminated with a cover flashing. This ensured successful waterproofing whilst not compromising the integrity of the specified system.

Richard Sawyer, construction and surveying manager with Tilbury Contracts, said:

“The roofing installation for the project was completed on time and to budget and has helped provide a sophisticated and desirable place for people to live in the heart of Belgravia.  The use of Hydrotech and the Blackdown green roofing system from Alumasc complemented the build perfectly – Hydrotech is a very secure system which is easy to work with and suited the awkward detailing better than any alternative product would have. The green roof is not only visually pleasing but provides strong environmental credentials whilst offering additional benefits such as noise insulation.”

Alumasc’s Hydrotech is a hot melt system which provides seamless waterproofing ideal for high performance green roofs, podiums and highly detailed waterproofing or water feature schemes. It is manufactured using a minimum of 10% post-consumer recycled material, is BBA accredited and has European Technical Approval.

Blackdown Green Roofs from Alumasc are constructed from a range of components that replicate the natural growing environment for plants, without requiring the same depth and weight of construction.

A Blackdown green roof from Alumasc provides one of the main features at the new School of Architecture and Construction at The University of Greenwich.

Officially opened in December 2014, the £78m new-build development is based in Stockwell Street within Maritime Greenwich on the UNESCO World Heritage Site. The project also included a new library, and features a series of terraced roofs, comprising 14 interlinked teaching gardens, forming the largest multifunctional roof space in London.

To facilitate this pioneering green roof design, a total of  3,407m² of green roofing System from Alumasc was specified by architects, Heneghan Peng, and Landscape Architects Allen Scott, and installed by Blackdown.

The new building had to be ‘demonstrably sustainable’ in the sense that both it, and its facilities, minimise their environmental impact and use of resources. The Blackdown green roof system creates a living laboratory where the sustainability of new ideas in landscape and architecture can be tested, and innovations developed and applied.

Glenn O’Brien, Architect at Heneghan Peng, commented:
“Our design proposals had to reflect the location’s status as a UNESCO World Heritage site while remaining sensitive to the neighbouring buildings, particularly the residences to the rear of the site. Incorporating the interlinked landscaped roofs allowed us a creative approach in dealing with these challenges.

“The green roof system underpins all of the landscaping on the roofs. We see it as the base infrastructure that allows for either soft or hard landscaping permutations. This proved very useful as the design progressed with different planting options, and we were secure in the University of Greenwich knowledge that the green roof system would be able to accommodate them. The zero-fall system also allowed us to achieve very large spans and roof areas with minimum difficulty.

“There is naturally a great deal of excitement about the future of research at the University of Greenwich and these roofs are already helping students and staff to extend their understanding of environmental infrastructure and of landscaped and green spaces across increasingly urbanised areas.”

The 14 interlinked terraces have already been received a BREEAM Innovation award due to their educational and research aims. Blackdown green roofs from Alumasc are constructed from a range of components that replicate the natural growing environment for plants, without requiring the same depth and weight of construction.

Green roofs absorb CO₂, improve a building’s thermal performance, increase rainwater retention thereby reducing storm water run-off, and reduce the life-cycle costs of a roof by protecting it from climatic changes, UV light and mechanical damage.

Alumasc Roofing Systems along with Mitie Tilley Roofing have recently completed the installation of a 1500 m² Derbigum high performance waterproofing system at Crown Bevcan, Carlisle.  Crown, UK beverage can manufacturers and one of the largest packaging companies in the world, were investing £2 million into the upgrade of their production line at Botchery.

As the 3rd highest producer of beverage cans globally and with net sales in 2014 of $9.1 billion, it was essential that Crown had peace of mind that any refurbishment works carried out at their Botchery plant would result in the waterproofing integrity of their works being guaranteed long term. To this end, Alumasc Roofing were approached to provide a waterproofing system that could be installed with this key aim in mind.

Richard Emerson, Alumasc Roofing Area Manager and the Alumasc Technical Team worked very closely with the Client and Mitie Tilley Roofing to ensure the waterproofing solution specified met the demanding requirements of this project and site conditions.

Challenges:

The most challenging aspect of the project was to keep the site live with no interruption to the production process. This was overcome with thorough planning and organisation. The Client, Mitie Tilley Roofing and Alumasc worked closely to facilitate site deliveries at timed intervals and coordinate site inspections to strict time schedules.

Design Considerations:

Communication was key with this scheme and attention to detail was paramount. The existing building required a robust and versatile waterproofing system to upgrade the manufacturing office, yet the aesthetics of the original building had to be taken into account.

Allied to these requirements, the waterproofing specified had to have superior performance characteristics in relation to the prevention of external fire spread and penetration.

The Derbigum Solution

Taking all these factors into account, Derbigum was the natural choice not only due to its ‘unrestricted’ classification in relation to fire, but also the Alumasc 30 Year Insurance Backed Warranty offered for this project.  The Derbigum system provided superior performance and waterproofing longevity for the future of their works.

Derbigum is a BBA approved system, with a life expectancy in excess of 30 years.  It is suitable for flame-free and cold application to warm roofs with metal, concrete or plywood decks and inverted roofs with concrete decks.

Alumasc along with Cambridge Flat Roofing are currently installing over 6500 m² of podium, roadway, communal and private gardens for the Stoke Quay, Ipswich project.

Stoke Quay is a large development of private & social housing for Genesis Housing, built by ISG construction as a flagship project at the Quayside in Ipswich.

The project utilises the Hydrotech Hot Melt Waterproofing System, Derbigum GC Waterproofing and Blackdown’s Green Roof system.

Stoke Quay has some extremely challenging elements to its construction as the site will need constant access to all areas due to the need to be able to continuously deliver products in a very small, constricted area.

The waterproofing system for the project needed to be versatile & Robust to withstand large volumes of traffic delivering building materials. Once complete the waterproofing will then have Asphalt road ways applied above. The chosen system also needed to facilitate a phased installation and withstand the weight aspect of installing hard and soft landscaping.

Alumasc Roofing Systems showed that having a complete Hydrotech, Derbigum & Blackdown Green Roof system met the requirements & stood out as the best value solution. The Alumasc waterproofing system for this project comes with a 35 Year warranty.

The systems’ versatility allowed for phased installation to the details & upstands first and also allowed for the phased installation to the perimeter details and up-stands to be carried out first and also allowed for all trades to continue work along with no disruption to deliveries. Once these areas were completed, the Hydrotech system was installed to the flat area, followed by application of a Blackdown Intensive Green Roofing System. The Hydrotech membrane was also used for tanking walls and for expansion joints, again indicating the systems versatility.

The robustness of the Hydrotech Waterproofing System combined with a Derbigum GC 5mm protection layer allowed for the waterproofing of the access roadway, which was then left exposed/uncovered to allow vehicles to deliver trade materials. At a later date the roadway waterproofing was covered with the Alumasc FC-6 & road asphalt. For the green roof areas the Blackdown Green Roof Drainage board also showed its robustness by allowing dump trucks to drive over it to distribute the engineered Blackdown intensive roof garden substrate, along with the required planting specified on the scheme.

Frank Besant, Area Manager of Alumasc Roofing Systems along with The Alumasc Roofing Systems Technical Team worked very closely with Richard Jackson Engineers, James Blake Associates, Living Architects and ISG in various pre-contract meetings to ensure the details and products specified met the extremely challenging requirements of this project and site conditions.

185-221 Buchanan Street is a new £70m mixed development comprising 11,400m² of retail space and 49 residential units. Owned by Land Securities, the development features a large rooftop garden which required a robust waterproofing solution.

BDP Architects specified both Alumasc’s Hydrotech hot melt structural waterproofing system and green roof on the scheme due to the benefits offered by a single-source solution and, of course, the quality of the products.

One challenge on the project related to the architect’s intricate roof detailing, which meant a close working relationship with Alumasc’s technical team was developed from the outset. As a hot-melt system, and due to its versatility, Hydrotech was ideally suited to accommodating this and was perfect for use under the green roof.

Alumasc’s green roof system addressed the need for a suitable growing medium to be supplied that could be deposited onto the 5-storey building’s roof in large volumes. This was required as a result of the development being in a busy city-centre location. These issues were overcome and the intensive green roof garden was installed in an efficient manner. In total, over 4,000m²  of Hydrotech and 2,000m² of green roofing, was installed.

Commenting on the project, Kath MacTaggart, landscape architect at BDP, said:

“As with any roof garden project, the challenge is in the detailing of all interfaces and logistics to ensure that a system is watertight. We used Hydrotech at Buchanan Street as it was part of the proprietary Alumasc green roofing system and therefore had the benefits of a fully guaranteed system. To date, we are very happy with the results.”

Area Manager for Scotland at Alumasc Roofing, John Kelly, adds:

“It was great to be involved with such a celebrated development in this major area of Glasgow. The Hydrotech system will ensure the integrity of the roof for many years to come, whilst the green roofing provides an attractive outdoor space for residents to enjoy.”

Hydrotech is a BBA approved, fully warranted waterproofing system, designed to last the lifetime of the structure it is applied to. It has European Technical Approval and is FM Approved. Alumasc green roof systems, under the Blackdown brand, are available in Intensive, Bio-diverse and Extensive application categories with a wide range of planting options.

The Buchanan Street roof garden joins a long line of prestigious developments that have benefited from the quality and expertise offered by Alumasc Roofing systems.

Alumasc’s Hydrotech hot-melt waterproofing system has been successfully installed at London’s County Hall, one of the capital’s most iconic landmarks.  Located next to the London Eye on the South Bank, County Hall was previously the HQ for GLC.  It is now a popular hub for arts, entertainment, eateries and accommodation.

As part of a four-year refurbishment programme, County Hall Estate Management (CHEM) needed to remove and replace all existing road surfaces at the location, some of which formed a podium deck structure above the boiler room, offices for the London Eye and tanks for the London Aquarium, containing rare and valuable species.

Hydrotech waterproofing was put forward on the scheme due to its ease of installation, 20-year warranty and impressive 50-year track record of zero product failures. The system was expertly installed by Alumasc registered installer Caretec, who have worked with the product for many years.

A major technical challenge on the scheme was that a hot asphalt layer would be installed on top of the Hydrotech system. Precautions had to be taken to minimise the risk of reactivating the Hydrotech membrane on application of the hot tarmac.  Alumasc’s technical team worked closely with Caretec to assess the risks at different stages of the installation and to ensure that the new asphalt was laid on an appropriate protective membrane at the right temperature.

An additional challenge was the heavy flow of traffic in and around the site. A constant flow of vehicles to surrounding leisure facilities meant that disruption to site facilities had to be minimised, whilst the installation of Hydrotech continued.  Due to the versatility of the product, this was a requirement that could easily be met.

Speaking about the project, Mike Foster at Caretec, said: 

“The existing road surface had reached the end of its life and was allowing water ingress into the basement area below.  Installing Hydrotech as the waterproofing membrane layer means that the basement areas are effectively protected for the lifetime of the structure. This was important to the client, given that these spaces are integral to the daily running of many key attractions such as the London Aquarium and London Eye. We’ve used Hydrotech for years and have always been very pleased with how easy it is to install, and how well it performs.”

Hydrotech is at the leading edge of waterproofing technology, offering a lightweight, flexible and self-healing membrane.  It is ideal for use at zero falls on inverted green roofs and hard landscaped podium structures, particularly in new build applications. Hydrotech is manufactured using 10% post-consumer recycled material, is BBA accredited and has European Technical Approval.

Alumasc is proud to have supported a gift appeal for children aged 0-18 years old run by St. Helens Council’s Children and Young People’s Service, the purpose of which was to help make a difference to the lives of underprivileged children in St Helens.

To help bring back the magic of Christmas to those who aren’t as lucky as most of us, The Children and Young People’s Service asked local individuals and companies to buy an extra gift whilst doing their Christmas shopping and to drop it at a nearby collection point.

Staff from Alumasc came together to support the cause, donating a selection of gifts suitable for a variety of ages to help bring smiles to the faces of local children.

Councillor Alison Bacon, Cabinet Member for Children and Young People’s Services said:

“It is very sad that while most people look forward to the festive season there are children in St Helens who have little or nothing to look forward to with the arrival of Santa very unlikely. This is why this appeal is so important to help families out at this time of year.”

Linda Sweeney from Alumasc says:

“This is such a worthwhile initiative to support. There are children out there who won’t get a single present this Christmas for one reason or another. Knowing how much other children will receive this Christmas, it is great to help those less fortunate by giving them a special gift and making them happy

The presents were distributed to local Children, who without the campaign, would otherwise have been left with no gifts at Christmas.
