The Liquid Roofing and Waterproofing Association (LRWA) is a UK member organisation of manufacturers of liquid applied coatings for buildings, professional coatings contractors and associated trade suppliers. ==History== The association was formed in the 1970s and was originally known as the BRCMA (Bituminous Roof Coating Manufacturers Association). The primary purpose of the association was to promote good practice in all areas of the UK bituminous roof coatings industry. The late 1980s and early 1990s saw the rise in popularity of non-bituminous products and in particular liquid roofing. Recognising this trend, the association reinvented itself as ELRA (European Liquid Roofing Association), now focusing solely on liquid roofing systems. The 'European' tag reflected the associations involvement in the drafting of European standards for all areas of liquid roofing. In 2005 a second reinvention took place as ELRA became ELWA (European Liquid Waterproofing Association) in recognition of the wider applications for liquid waterproofing products, for example the protection and waterproofing of car park decks. In 2010 the association identified a need for an industry voice for liquid roofing, which was and remains the fastest growing sector of the roofing market in the UK. The 'European' label was dropped as the association re-launched as LRWA (Liquid Roofing and Waterproofing Association).〔http://www.lrwa.org.uk/Our-History〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Liquid Roofing and Waterproofing Association」の詳細全文を読む スポンサード リンク
