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 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.
