Soudal Soudagum Hydro is a ready-to-use, solvent-free waterproofing membrane designed for internal and external use. Applied by brush or roller, it forms a flexible, durable barrier over concrete, screeds, cement sheeting, and tiles. Its single-component formula makes it easy to apply and ideal for wet areas, balconies, and exposed surfaces.
It can also be used for short-term rooftop repairs, roof edges, and chimney flashings. Reinforcement with fleece adds strength for demanding jobs. Once cured, it withstands ponding water, bridges cracks, and can be tiled over while remaining permanently flexible.
