Social Media: Twitter / Facebook / Linkedin

Radmat Building Products are suppliers of high performance waterproofing materials marketed via specification assistance to architects, consulting engineers and quantity surveyors. The company is committed to providing technical support to the specifier and construction team with the elements of service that give comfort and a satisfactory waterproofing solution to meet the parameters given. Our range of products include:

MedO Green Roofing

MedO is a green roof solution that uses established green roofing technologies in a simple and straightforward way. A variety of green roof solutions can be created - from low maintenance sedum matting and wildflower meadows, to landscaped roof gardens with lawns, shrubs and water features.

PermaQuik PQ6100 Monolithic Membrane Roofing

PermaQuik 6100 Monolithic membrane roofing system is a one part, hot applied, seamless rubberised self-healing membrane made from bitumen, natural rubbers, and a blend of polymers, further reinforced with a high tensile polyester fabric. This mix combines excellent waterproofing performance with toughness, flexibility, and strong adhesion to a variety of substrates.

ParaFlex Liquid Applied Cold Resin Membrane

ParaFlex is a fast curing, cold applied polyester resin waterproofing system. It is ’wet on wet’ between layers so it doesn’t need to be left to cure between coats. This means a faster application to give a continuous monolithic waterproof material.

EshaUniversal Single Layer Roofing Membrane

Esha is universal waterproofing and roofing membrane not only made from recycled end-of-life bitumen polyolefin products it is also 100% recyclable. A patented manufacturing method Esha is a shrink-free, fully adhered membrane that is more flexible and stronger than conventional membranes and has greater stability and durability.

EshaFlex Reinforced Bitumen Membranes

EshaFlex membranes feature Groove Technology®, a patented underside finish that ensures the heat acts only where it is needed, reducing warming of the membrane and increasing melting of the PE foil.

EshaPlan Single Ply Membranes

Single Ply Membranes for use as mechanically fastened or adhered roof waterproofing on flat or pitched roofs.  Suitable for refurbishment and new build applications.

Green & Blue: joined up thinking to reduce flood risk

December 2017

Back in 2000 the roofing industry got behind the emerging demand for green roofing, which was being significantly lead by the London Borough Planning Offices, the Mayor’s ‘London Plan’ and organisations such as livingroofs.org.

Whilst there are many positive drivers behind the reasons for using green roofs the main drivers could be seen as incident rainfall control, air pollution and biodiversity. Fast forward through the evolution of Green Roofs, and so called ‘Brown’ Roofs (un-planted roofs left to nature), the roofing industry are now investing in the development of Blue Roofs.

Blue Roofs are a method of providing a Sustainable Drainage System (Suds) at roof level. They provide attenuation of rainfall at a far higher level than the Green Roof that is typically installed over the Blue Roof.

Consisting of a water storage medium, typically a cellular geocomposite drainage/retention board, and a discharge control mechanism, Blue roofs attenuate rainwater rather than drain it as quickly as possible. Correctly designing the Blue Roof releases attenuated water at the required discharge rate of site, providing the integral source control and attenuation required by a SuDS system without the requirement for land consuming ponds and retention basins or below ground geocellular storage tanks. Blue Roofs can also be used in conjunction with these more traditional water control methods.

Incorporated in an inverted roof construction the Blue Roof elements are installed above the insulation and thermal sheet, and can be finished with a green roof (extensive, wildflower, biodiverse or intensive), paving or gravel ballast. Waterproofing materials such as Radmat’s PermaQuik PQ6100 Hot Melt Monolithic Waterproofing are BBA Certified for zero falls applications with a durability for the lifetime of the building, and are ideal for Blue Roof applications where security against water ingress is a priority.

Jonathan Ward, an associate director at Arup simply describes a Blue Roof as ‘a flat roof allows stormwater to be temporarily stored and drain away slowly over a few hours, thereby reducing flood risks.’ What’s more the roof area doesn’t have to be significant; a roof of less than 300m2 can attenuate 94% of the rainfall volume of a 1 in 100 year 6 hour storm event, draining over a 27 hour period.

Blue Roofs are not a new idea. They have been around in one form or another for well over 60 years, in the UK, Europe and the USA. They can be used for attenuation, storage, grey water harvesting or a combination thereof. They can go even further, like the University of Toronto’s Innovation Complex, which has a zero-runoff roof that incorporates a green roof, wind turbines and solar PV.

So why aren’t we building more blue roofs in the UK? The answer to that probably lies in scepticism, outdated concerns over flat roofing materials and a lack of guidance documents and legislation.

To breach these boundaries a pan industry working group has been established by the National Federation of Roofing Contractors Joint Flat Roofing Technical Committee. Consisting of the NHBC, BBA and representative of a number of waterproofing trade bodies, waterproofing manufacturers and drainage manufacturers the committee intends to tackle the issues of certification and Codes of Best Practice. With these instruments in hand the committee will move on to pressing government and the EA to look more closely at the positive contributions to flood risk management that Blue roofs can have, to both New Construction and existing buildings.

Radmat supplied roofing systems to Alder Hey in the Park

March 2017

Leading flat roof waterproofing system provider Radmat Building Products has supplied an award-winning roofing system for the new £237 million Alder Hey in the Park children’s hospital in Liverpool. The system provides high standards of environmental performance, long term waterproofing integrity and has enabled the creation of three stunning green roofed ‘fingers’ that connect the hospital with the surrounding parkland.

• The UK’s first NHS hospital for children built entirely in a park

• Sustainability award winner: Green Roof Project of the Year 2016 (UK Roofing Awards)

Alder Hey is the first hospital in Europe to be built entirely within a park. The 52,600m2 main hospital and 9,500m2 outpatients department was designed by architects BDP in consultation with patients, their families, the Princes Foundation and National Arts for Health, and was inspired by a drawing made by a 15-year-old patient. The 270-bed hospital is one of the most sustainable ever built, with more than 50% of its energy generated on site.

Laing O’Rourke appointed Radmat approved contractor, Prater, to construct the green roof on the strength of its technical expertise and previous experience on major healthcare projects and green roof systems.

A key feature of the hospital’s design is the three iconic green roofed ‘fingers’ that curve downward from the fourth floor of the building to the ground level at a 45-degree angle, connecting the hospital wards with the surrounding parkland.

The structure posed installation challenges and in order to safely waterproof the steep slopes the installation team to work using a mixture of abseiling equipment and telelifters to apply two coats of a Liquid Applied Membrane, which was developed for use in verdant roof gardens. The liquid applied system was chosen for speed of installation and its elastomeric properties, allowing it to expand and contract with the building to ensure a reliable seal. The ease of application also meant a safer process for those working on the less accessible areas of the roof.

This was followed by installing Radmat’s ProTherm Inverted Roof Insulation, specifically designed to give effective, long-lasting insulation on inverted roofs. The green roof was completed with a substrate-based Wildflower Meadow System.

The main hospital and outpatient’s department have already won a number of RIBA Awards and can now add a Roofing Award to the many accolades it is no doubt going to receive. Radmat and Prater were awarded the ‘Green Roof Project of the Year 2016’ in the Sustainability category of the UK Roofing Awards for their work on the hospital, which is a home-from-home for children who need care, and gives them access to play areas, fresh air, natural light and striking views of the park.
