SIG Design & Technology has launched the next generation of its AH+ liquid waterproofing system with improved levels of robustness and usability.
The new AH+ is a wet-on-wet, cold-applied liquid water-proofing product that’s fully reinforced with a polyester fabric. The one-component liquid system offers benefits including ease of application, fast curing times and, with a low VOC content, it is fume free and almost odourless. The company says the superior performance of the liquid waterproofing system makes it suitable for new build or refurbishment projects.
Available in two versions, the AH25+ and AH15+ use different weight reinforcement fleece and coverage rates, and are available with 25 and 15-year warranties respectively. AH+ systems are BBA certified, certified to EN13948: 2007 for Green Roofs, and fire tested to meet BS476-3 2004.
The SIG Design & Technology Accredited Contractor scheme (DATAC) provides assurance that the company’s roofing systems are correctly installed.
