What should you be looking for? Making the right liquid choice... As the Liquid Roofing and Waterproofing Association (LRWA) reveals its latest market size figures, CEO of the association, Sarah Spink, discusses product choice and application best practice in the fastest Liquid roofing and waterproofing has gone from strength to strength in 2017, something which is expected to continue in 2018. Recent figures from research undertaken by the LRWA recorded a 35% growth in its members’ turnover – measured in m2 – for liquid applied waterproofing since 2013. During the last four years, a rise in LRWA membership also reflects sector growth, with an increase from 16 manufacturer members in 2013, to 25 in 2016 – which has seen the association’s collective turnover grow by 98% – meaning liquids is now the fastest growing sector of the flat roofing market. New liquid systems As with any market sector, the successes of rapid growth does present its own issues, and because of the increased demand for liquid waterproofing, there has been an influx of new manufacturers emerging into the market, as well as an increase of imported products from growing sector in flat roofing overseas. Whilst manufacturers and contractors must relish the new business opportunity, it’s important to ensure high standards are still being met. Some of the new liquid waterproofing systems emerging onto the market – often sold through distribution networks – are substandard and have been developed without any testing or certification, so there is a risk that some of these products are simply not fit for purpose. This is an issue within the industry which the LRWA continues to try and combat, and will do so throughout 2018. There are some good product systems sold through distribution networks, but in some circumstances, operatives aren’t being trained properly or don’t have the field service personnel to ensure a quality of application. Liquid products vary considerably depending on different chemistry types, so it is important that operatives are fully knowledgeable with regard to the performance and behaviour of the different systems, as well as being fully trained in the application. Product choice In the flat roofing sector where poor product performance could lead to water ingress, the contractor needs to be able to pass peace of mind upstream through the delivery partners, all the way to the principle designer, the client and the end user. It’s therefore important for the contractor to seek advice from a trusted trade association such as the LRWA – which is the only recognised body in liquid applied membranes to produce compliant technical guidance notes and Codes of Practice – before choosing a product. For a contractor to know a product is fit for LRWA VIEWPOINT Sarah Spink, LRWA CEO: “In the flat roofing sector where poor product performance could lead to water ingress, the contractor needs to be able to pass peace of mind upstream through the delivery partners” A technical team based on the UK is vital to ensure product and application advice can be given if required “It is worthwhile for any contractor to consider what service a manufacturer offers, aside from the product benefits, before specifying any liquid waterproofing system”
