New Liquid Waterproofing Training Videos
We have launched a set of liquid waterproofing training videos for AH+, the next generation of our popular liquid waterproofing system.
These videos will provide you with a practical understanding of how AH15+ and AH25+ are correctly installed and will give you a useful insight into both the principles and the process of liquid waterproofing, together with an understanding of the expected appearance of the finished roof, joints and details.
SIG Design and Technology also provide a one-day course in AH+ liquid waterproofing for our DATAC accredited contractors. The training sessions take place at the SIG Design and Technology Roofing Academy in Shepshed, near Loughborough. If you would like to find out more about the training, download our Training Academy Brochure or contact Sara Jelly, Roofing Academy Manager via our contact form.
SIG Design and Technology is a member of the Liquid Roofing and Waterproofing Association.
What is AH+ Liquid Waterproofing?
Unpleasant odours, restrictive weather conditions, differing application processes, multi component systems – combined, these make the successful installation of liquid systems very challenging. Hydrostop AH+ has been developed with these attributes in mind to produce a membrane which is considerate to the needs of the installer.
Hydrostop AH+ is a liquid waterproofing system that eliminates many of the challenges faced, to provide a product which is very practical to use. Hydrostop AH+ Liquid Waterproofing Systems are the latest innovation in liquid roofing technology combining the benefits associated with existing alternative products, to create a new user friendly
Hydrostop AH+ is a wet-on-wet, cold applied liquid water-proofing product that’s fully reinforced with a polyester fabric. An extremely versatile and innovative one-component liquid system it offers many benefits including ease of application, fast curing times and with low VOC content it is fume free and virtually odourless. It can also be applied in practically any conditions and at low temperatures. The superior performance of the liquid waterproofing system makes it ideal for new build or refurbishment projects and gives superb results with complex detailing.
