Metal Substrate Waterproofing
Specialised Protection for Metal Surfaces
Metal substrates including box gutters, camper trailers demand waterproofing solutions engineered for their unique challenges. Thermal expansion, substrate movement, and exposure to the elements require membranes that flex, bond, and perform where conventional products fail.
Soudal Soudagum Hydro
A liquid-applied, elastic waterproofing membrane specifically formulated for metal roofing, gutters, flashings, and cladding. Creates a seamless, flexible barrier that moves with metal substrate expansion and contraction without tearing or delaminating. Excellent adhesion to Colorbond, Zincalume, aluminum, and galvanised steel—even in exposed coastal environments.
Fast-curing formula withstands rain shortly after application, keeping your project on schedule. Applies easily by brush or roller for detail work around penetrations, valleys, and complex junctions. UV-stable finish maintains waterproof integrity under constant sun exposure.
Ideal for roof repairs, gutter remediation, parapet waterproofing, and preventing leaks at problematic metal-to-metal junctions. Works where traditional membranes simply can't handle the substrate movement.
Built for Real-World Conditions
Metal substrates face relentless thermal cycling, corrosive atmospheres, and mechanical stress. Standard waterproofing products weren't designed for these conditions. Soudagum Hydro was. Whether you're addressing existing leak points, waterproofing new installations, or protecting vulnerable flashings and transitions, you need a membrane that bonds tenaciously and flexes indefinitely.
