UPDATED PHONE NUMBER - To speak to one of our team, please call 0333 987 4581. LRWA, the Liquid Roofing and Waterproofing Association consists of the leading manufacturers of liquid applied waterproofing, approved contractors and related materials suppliers. The Liquid Roofing and Waterproofing Association represents the fastest growing sector of the construction industry. Suitable for new-build and refurbishment projects, liquid membranes have delivered proven performance in the UK since the 1970’s with literally millions of square metres laid. Our aim is to raise awareness of both the technical and financial benefits of specifying liquid applied waterproofing systems and provide independent advice for specifiers. All our manufacturer members have to meet stringent quality criteria before membership with the LRWA can be approved. This includes: Having their own quality systems that meet ISO 9001 standards. Providing trained technical staff to give support in the office and out on site. Achieving independent product accreditations such as BBA and ETA certificates. Developing their own approved contractor schemes and providing full training for these contractors. Supplying systems with a minimum 10 year guarantee. We provide technical guidance for specifiers through Guidance Notes and the LRWA Code of Practice, and our members work together to ensure liquids are represented within industry standards such as the BREEAM Green Guide to Specification. Through partnerships with other roofing trade associations, the National Federation of Roofing Contractors and the Institute of Roofing, the LRWA is working hard to move the flat roofing industry forwards and ensure quality products with quality installations.
