Liquid Roofing


Hydrostop EU AH-25 is an innovative one-component liquid waterproofing system which offers significant advantages over conventional systems. It can be applied under practically any conditions, including cold days above 0oC and on moist surfaces (7% or less). Hydrostop EU AH-25 is fast-curing and easy to apply. Its superior performance makes it ideal for any small scale, large commercial, new build or refurbishment projects.

Hydrostop EU AH-25 is based on alpha-hybrid, silane terminated polyether technology. Not only does it exceed most performance criteria of other liquid systems, including polyurethane and PMMA, it also eliminates many of the disadvantages of these products. This product is the first product in our range to offer a low odour 25 year solution that is solvent and isocyanurate free making it suitable for highly sensitive flat roof areas adjacent to windows and ventilation intake plants.

Hydropstop EU AH-25 is grey in colour.  Custom colours are available.

Hydrostop EU AH-25 complies with the European Technical Approval Guidelines for liquid applied roof waterproofing kits (ETAG 005) for all listed use categories.
