With the addition of new products and the launch of its new Drainage Calculator software, Alumasc’s Harmer brand offers benefits to all professionals involved in the design and specification of rainwater and roof drainage products.

Alumasc recently unveiled the innovative Drainage Calculator software at Ecobuild 2012, where it was heralded a major step forward for the industry. It is quick and easy to use, turning the process of foul drainage system sizing and flat roof and eaves drainage calculation, into an elementary process.

Another significant development is the introduction of a comprehensive range of cast iron rainwater outlets to create competitive choice for designers who have a preference for cast iron drainage products. The new range of outlets provides for inverted and warm roof construction whilst improving fire safety as well as accommodating wheel load capacities to meet the requirements for car park and podium deck drainage applications.

Alumasc’s Harmer brand is already the leading name in flat roof drainage, with an established product range consisting of aluminium and insulated rainwater outlets. A new Mini Balcony Outlet is now included within the aluminium range, featuring a shallow sump and interchangeable gratings in stainless steel or nickel bronze for applications requiring improvement of finish and enhanced aesthetics.

The Harmer Modulock system consists of an all new product offer comprising an adjustable linear channel system that meets the requirements of Part M Level Access compliance manufactured in galvanised or stainless steel. The new Modulock offer also extends the successful range of adjustable deck supports by simplifying levelling and adjustability during and after installation. The introduction of these products has significantly improved the choice and cost efficiency of raised deck drainage solutions available for green roofs, terraces, walkways and ballasted flat roof construction.

The Harmer range is suited to different roof types including structural concrete, metal deck, timber deck, warm roof, cold roof, green roof and inverted roof.  Harmer Roof outlets can be used with all types of membrane including asphalt, built-up felt, single ply and wet-applied systems and are suitable for applications such as  flat and low pitched roofs, car parks decks, factories and workshops, balconies and roof terraces. All products feature premium quality materials chosen for their inherent strength and durability, for ease of installation and long-life service.

Paul Hetherington, MD of Alumasc Rainwater and Drainage, comments: “No other manufacturer offers such an extensive roof drainage range at such competitive prices. The on-going development of our products and services is essential in supporting the industry – in addition to the improved range, Alumasc’s Harmer technical support is second to none and our new calculation software is proving a major benefit to contractors and specifiers.”

Harmer SML is the optimum choice for soil and waste pipework, offering many advantages for contractors and end users both in terms of installation and performance. Cast iron is inherently robust and highly resistant to damage while its outstanding dimensional stability and high tensile strength eliminate the need for expansion joints and reduce the amount of fixing bracketry required. It is also non-combustible, offers excellent noise attenuation, tested to BS EN 14366: 2004 and is 100% recyclable.

The pipework comes with the option of two-part ductile couplings or unique stainless steel ‘Duo’ couplings that enable faster fixing and built-in electrical continuity, whilst the fixing positions on one side of the coupling allows ease of fixing in confined spaces. The unique Duomat Fixing Tool enables contractors to reduce installation time for the SML system by 50%.

The Duomat Fixing Tool is unique to the Harmer SML system and is suitable for use with any power drill. The tool enables both of the coupling bolts to be tightened simultaneously to the optimum torque setting of 7Nm-9Nm. Two independent preset clutches ensure the correct torque setting, irrespective of the pipe tolerances. The simple toggle adjustment allows for perfect Allen bit alignment for all couplings from 50mm to 300mm diameter and once fitted, the stainless steel duo coupling is totally secure.

John Whybrow, of Alumasc’s Approved Installer PSI, regularly installs Harmer SML using the Duomat Tool. He comments: “Having installed drainage systems both with and without the Duomat Tool, I can state quite confidently that Duomat installations take around half the time.

“The efficient simultaneous tightening of the Duo coupling system has resulted in impressive time and labour savings on site for a significant number of our installations.”

Harmer SML pipes are available in standard 3m lengths, with diameters of 50mm-400mm plus a comprehensive range of fittings and accessories. The system is BBA Agrément Certified fully compliant with BS EN 877 and is CE Marked to European Standards.

The benefits of Harmer floor drains are clear – just two body types and three interchangeable styles of grating meet the needs of almost every imaginable floor drainage application, negating the need for over a hundred alternative components.

The range has been designed with the needs of fast track building projects in mind, where installation speed is paramount. All models offer direct connection to the drainage system and grating assemblies are adjustable.

In use, Harmer floor drains surpass the brand’s reputation for durability and longevity of performance. Their high quality engineering pays off in a high flow rate that meets and often exceeds current British Standards. The drains are corrosion resistant, and the smooth finishes are both tough and hygienic.

Designed by Dyer Associates of London, Gloucester Quays is a £200million scheme, comprising over 150,000m² of floor space and an 18,000m² Factory Outlet Centre. Located alongside the Gloucester and Sharpness Canal, the development is a key part of the regeneration of Gloucester’s historic town centre, setting a benchmark in contemporary design. The main contractor was Bovis Lend Lease. 

Alumasc worked closely with installers T Clarke Bristol Ltd to overcome the challenge presented by complex roof build-up at Gloucester Quays’ car park. Various areas of asphalt and liquid waterproofing membranes demanded the specification of a robust yet versatile drainage system able to accommodate the differing build-up thicknesses. Harmer Car Park Outlets were fitted using a double clamping ring which could be adjusted to suit the requirements of the waterproofing layer.

The Harmer system enabled fast installation, with a flush-fitting, hard-wearing result capable of withstanding cars and light commercial vehicles to a maximum single wheel loading of 1 tonne and total weight of approximately 255 kg/m2.

The Harmer Roof Outlet range includes Detail outlets for use in multi-level car parks, balconies and gulleys, AV high capacity outlets for flat roof projects and Insulated outlets used mainly in metal deck warm and inverted roof installations. They are all lightweight, durable and non-corrodible, offering ease of installation in projects that present awkward roof detailing. Offering high performance and minimal maintenance requirements, Harmer Roof Outlets are diecast in LM6 aluminium silicon alloy to BS 1490: 1988, offering a BBA approved powder coating on grate and clamping collar.

In accordance with Alumasc’s environmental policy, Harmer Roof Outlets are manufactured under the ISO14001:2004 environmental management standard using 100% recyclable Aluminium.
