PRODUCT PROFILES | DRAINAGE, PLUMBING AND WATER SUPPLY Chamber assemblies meet revised standards 68 BUILDING PRODUCTS | JULY 2017 Syphonic system ensures roof shape is maintained The roof of London's new Design Museum (previously the Commonwealth Institute) has had Geberit's siphonic drainage solution installed, allowing its unusual parabolic shape to remain intact, while providing water drainage. To retain the roof's unusual shape, piping could only be included in two existing internal raked columns. The Design Museum forms part of the Hollandgreen development, located off Kensington High Street, which is a mixed use residential and public sector project, incorporating 56 highend apartments grouped around the museum. In addition to Geberit Pluvia the project also features Geberit Mapress piping, Geberit Silentdb20, a sound-deadening drainage solution, and luxury shower-toilets, Geberit AquaClean Sela. Mike Carter for Arup, who were heavily involved in the design and specification of the project said: “Geberit Pluvia could be installed without impacting on the visual aesthetic. “Because of the negative pressure, no slopes were needed for the discharge pipes leading to the outfall locations at the building perimeter, meaning the installation was simpler and needed far less void space at high level in the basement." www.geberit.co.uk Offering a range of highperformance Adoptable Access and Inspection Chamber Assemblies, Brett Martin has released a new range, which is designed to meet the requirements of Sewers for Adoption (SfA7). Brett Martin’s range of Adoptable Access and Inspection Chamber Assemblies, carrying the BSI Kitemark KM 635998, are tested to EN13598-1 and satisfy both the requirements of Sewers for Adoption 7 and Building Regulations Part H1. Chris Dawson, sales director at Brett Martin said: “This combination of strength, loading capabilities and exceptional sealing means that our high performance chamber assemblies offer a wide range of benefits to the installer and meet all of the latest regulatory requirements.” The 315mm Shallow Access Chamber Assembly complies with Building Regulations Part H1 to a depth of 600mm and SfA7 to a depth of 900mm. For deeper applications, the 450mm Inspection Chamber Assembly complies with Building Regulations Part H1 to a depth of 3.0m and SfA7 to a depth of 1.2m. Brett Martin also offers a range of Non-Adoptable Access and Inspection Chamber Assemblies in 280mm, 315mm and 450mm diameters. www.brettmartin.com Quick-installation rainwater system helps keep water at bay UK stockist and online retailer of metal rainwater systems Rainclear Systems has introduced the SnapIT extruded aluminium rainwater system, with the ability to click together without the need for nuts, bolts or washers. Available in 26 smooth finish colours for a contemporary look and textured black or ivory white (RAL 1015) to add traditional heritage character to your property. SnapIT also comes in 2 profiles; the half-round profile in 115mmm and 125mm sizes or vintage moulded profile in a 125mm x 100mm size. The round downpipes, with swaged neck to slot together without fuss, come in 63mm and 76mm diameters. James Wright, sales executive at Rainclear Systems, said: “At a cheaper price than either cast iron or cast aluminium, SnapIT is the perfect choice for home builders or installers going for high quality but keeping a close eye on time and budget as well. If you’ve worked with SnapIT before, I think you’ll be impressed by the introduction of the ‘swept’ bends on the offsets, shoes and bends. They have managed to improve an already stunning looking, long-lasting and easy-fit system.” www.rainclear.co.uk London hotel gets canopy drainage A major London development has been supplied with Harmer Building Drainage’s SML below ground drainage system. The project, sited at The Minories, Aldgate, saw the introduction of the first Canopy by Hilton hotel in the UK. Working with contractors PCW Drainage Ltd and A J Morrisroe, Harmer supplied below ground drainage for the hotel’s new double storey basement box. Wayne Willmott, national sales manager for Harmer Drainage said: “It’s an unusual site. The contractor constructed a double storey basement box and podium slab to support a 16-storey residential block and a 14-storey hotel extension. It covers a footprint of around 3,500m across a narrow site. There were multiple levels of earlier construction to work through, including foundations and piles that date back to the 19th century. “The construction required drainage with excellent load bearing strength,” continues Wayne, “as well as the assurance of durability and maintenance free, so our Harmer SML drainage was the ideal choice.” www.harmerdrainage.co.uk
