Alumasc is proud to announce that we have two sustainable and innovative green roof projects shortlisted at this year’s 2018 NFRC  (National Federation of Roofing Contractors) Awards, below we look back at the green roof projects…

Project One:

Tucked away in the rolling hillsides of Monmouthshire is The Decoy Bunker. The original bunker was built in 1941 and was designed as a special decoy target for German bombers.

The secluded bunker has now been fully restored and is now a unique holiday home.

As part of the design, the bunker needed to blend directly into the hillside, therefore, a highly durable waterproofing system that could provide full protection from the water travelling down from the surrounding landscape was needed. A green roof waterproofing solution that would provide the maximum blending effect was also required to give it the desired ‘camouflage’ effect by using the existing soil and grass from the surrounding landscape. Blackdown Drainage Layers, Intensive Substrate and Washed Pebble Ballast was installed to finish the green roof.

With Derbigum being a system that holds 40-year durability certification with the BBA (British Board of Agrément) – a Derbigum Black Anti-Root Built-Up System was the ideal solution. The Derbigum system sits below the green roof and provides a highly reliable waterproofing solution and maximum peace of mind for the future. Alumasc’s Registered Contractors Span Roofing carried out the installation with great results.

Project Two:

Blackdown are proud to have completed the sedum green roof at the Chester Bus Interchange site which is a £10 million ‘key enabling’ project and part of the wider £300m Chester Northgate Redevelopment.

The bus interchange is capable of handling 156 bus movements per hour & opened in early 2017. Blackdown worked alongside Lakesmere, who installed the Kalzip roof and Graham Construction the main contractor.

The project has a 3,434sqm sedum green roof with a varied pitch from 0-35 degrees installed over a Kalzip standing seam roof.

Blackdown would like to thank both Graham Construction and Lakesmere for the positive and close working partnership throughout the duration of this exciting project.

Alumasc’s Blue Roof system is a single source, fully warranted waterproofing and sustainable drainage solution.

Exploiting the combined expertise of Alumasc’s Roofing Division and Harmer Engineered Drainage Systems; allowing a truly single source solution that we believe is integral to a system of this nature. This is because the system has been tested by Alumasc working in conjunction with consulting engineers and test houses to guarantee system performance throughout the life cycle of the roof or podium.

Alumasc’s nationwide network of registered contractors combined with our own site monitoring team(s) ensures compliance with the warranty and codes of practice are observed through to completion.

This is followed by our Blu Roof leak detection policy applicable to all Blue Roof specifications or projects to provide further peace of mind to all parties involved.

From specification through to completion of installation one point of contact and one installation team provides a single source solution to the successful completion of the works thus limiting potential split responsibility.

Split responsibility may result in the use of various trades and contractors, which in turn may lead to installation errors, damage to materials or negative warranty implications.
Alumasc’s Blue Roof warranty assures the building owner that, if the roof fails to remain watertight as a consequence of latent defect in the Blue Roof Waterproofing System, Drainage Components, Accessories and associated surface finishes such as green roof as supplied by Alumasc, the integrity of the waterproofing will be reinstated.

This also includes details designed by Alumasc or faulty workmanship of the Alumasc Registered Contractor. Warranties of up to 40 years available.

The Triangle, the new international headquarters brings together all Cambridge Assessment’s Cambridge-based staff, currently based in 11 different offices across the city, bringing them all under one roof. The site is on what was previously Cambridge University Press’s Edinburgh Building on Shaftesbury Road Cambridge, to the South-East of Cambridge City Centre.

Designed by HLM/Sidell Gibson Architects, all flat roof areas utilised Alumasc Roofing Systems’ Hydrotech Hot Melt and Alumasc XPS insulation offering a total system solution. All upper main roof areas drain onto 3 x single storey podiums that have the Alumasc BluRoof Drainage System along with Blackdown Green Roof to provide a habitable space for people to enjoy. This BluRoof System comes with Alumasc’s single point warranty that provides the University with ultimate peace of mind for the foreseeable future. This assures the University that if the roof fails to remain watertight as a consequence of latent defect in the BluRoof Waterproofing System, Drainage Components, Accessories and associated surface finishes such as green roof as supplied by Alumasc, the integrity of the waterproofing will be reinstated by Alumasc.

Alumasc’s BluRoof system reduces and controls the peak rate of stormwater discharge from roof areas. Detention of storm water up to a prescribed maximum hydraulic head occurs, with subsequent discharge controlled over an elongated time period.

The BluRoof drainage strategies were introduced at design stage to help meet SuDS requirements and Alumasc worked extensively with Capita to achieve the required reduction in rainwater run-off.

The installation was carried out by Alumasc registered approved contractor Cambridge Flat Roofing acting as sub-contractor to Bouygues UK.

Wayne Farrington from Cambridge Flat Roofing says:

“This has been an excellent contract to be involved in, one of our first major BluRoof projects. The level of service and input from Alumasc’s Technical department, both internally and on-site along with Alumasc’s Customer Services team has been outstanding.

Combined with the Hydrotech BluRoof Structural Waterproofing system, a system we have significant trust and experience in installing, we feel we’ve delivered a project we can be proud of. The feedback we’ve received from our client has been extremely positive and we look forward to our next Alumasc BluRoof.”

Hydrotech Structural Waterproofing contains an impressive post-consumer recycled content of 30%, making it the choice of professionals in an ever-growing sustainable environment.

Independently verified by Underwriters Laboratories – Hydrotech offers 30% recycled content.

The Hydrotech component formula is a unique combination of recycled materials found exclusively in Hydrotech, including rubber crumb from used tyres, process oil and inert fillers, along with the basic bituminous element. These recycled products are typically disposed of via landfill, therefore, the heightened use of these post-consumer materials within this hot melt system helps save the landscape and the atmosphere.

REACH Compliance

Hydrotech is additionally fully compliant with the REACH legislation (Registration, Evaluation, Authorisation and Restriction of Chemicals), which originated as a mandatory regulation of the European Union, implemented to improve the protection of human health and the environment from the from the risks that can be posed by some materials.

Sustainability

Not only does Hydrotech contain sustainable raw materials, it also uses hydro-electrical power as the primary energy source in manufacture. These manufacturing procedures are independently audited to the ISO9001 Quality Management Standard, and the product is imported under Alumasc’s ISO14001 Environmental Management system, thus ensuring that upstream production processes are monitored for their environmental impact and that careful consideration are made in terms of packaging, transport and disposal to deliver as sustainable a construction product as practicable.

This particular hot melt system also has over 50 years of proven zero project failures worldwide, on projects of all types and sizes.

This project utilised 1,500m2 of Hydrotech Hot Melt Waterproofing and Blackdown Green Roof NatureMat. NatureMat is a vegetated mat consisting of a biodegradable base layer, a specially formulated substrate layer and a 90% mature plant cover comprising of 6 core species (predominantly Sedums) along with 13 randomly sown species. All grown to maturity in Blackdowns’s own fields in Somerset.

A roofing system was needed that would provide students with an environmentally beneficial solution that would help improve their lives. NatureMat provides that solution by helping clean the air from surrounding pollution and contributing to the required acoustic and thermal properties needed for this project.

Another benefit of this system is that the location in Glamorgan receives high levels of rainfall, therefore a system was needed that could absorb high levels of rainwater and deal with it effectively – Blackdown NatureMat is highly efficient in absorbing rainwater and along with Hydrotech Hot Melt Waterproofing having Zero Product Failures in over 50 years this system will provide the sports hall with a long, reliable and efficient Flat Roof solution for the long term.

Monoscreed is a fast curing PMMA based compound screed (solvent and isocyanate free) comprising of resin + filler + aggregate mix. The cold applied compound can be mixed at roof level and applied to concrete decks (3mm – 50mm) to bring deck levels back to tolerance i.e. zero falls’ thus reducing deck deflection/back-falls.

FAST CURE TIME

The system is unaffected by ambient temperatures, is rainproof within 15 minutes of being applied and will fully cure in circa 45 minutes, thus offering significant programme benefits when compared with more

APPLICATION TO SUBSTRATE

Monoscreed can be applied directly to suitably prepared cementitious concrete which is free from dust, dampness, laitance, grease, oil or other contamination, and if necessary primed with Alumasc Bitumen Primer. The system comes in pre-measured packs of components palletised to ensure easy transportation to roof level and accuracy of the compound mix.

OVERLAYING

Monoscreed is also suitable to be installed over Hydrotech 6125, Derbigum bituminous membranes & Caltech QC cold-applied liquid where necessary.

The prestigious new home for the School of Law and a new social hub is a key element in the major investment of £350m in world-class facilities for staff and students planned over the next decade at Queen’s University, Belfast. This facility provides several innovative teaching spaces central to which will be the Moot Court Room interactive teaching space.

Todd Architects specified a warm roof system of Torchtite Vapour Barrier, Alumasc Tapered Insulation and Mastergold Underlay topped with a Mastergold Mineral Cap Sheet – a full Euroroof warm roof system.

This roofing system utilised a tapered insulation scheme to help achieve sufficient falls to help provide a longer roof life for the building’s roof areas. With the existing deck being completely flat sufficient falls needed to be achieved to avoid any standing/ponding water which can form algae and moss over the years and shorten the membrane’s performance and life span.

The tapered insulation provided sufficient falls for the roof and met the required U-Values to help towards the building’s overall thermal performance.

All roofing work(s) were expertly carried out by Alumasc Registered Contractors Crown Roofing and within schedule.
