Duram S900: The Invisible Shield for Porous Building Surfaces

Advanced Penetrating Siloxane Technology for Maximum Protection

As your trusted Waterproof Supplier, we present Duram S900, a state-of-the-art, high-pH, siloxane-based water-resistant solution. This is not a surface film; it's a deep-penetrating treatment that migrates into the very core of porous materials. Once absorbed, it chemically reacts within the substrate to form a powerful, permanent water-repellent barrier below the surface. This revolutionary technology stops water ingress at its source while crucially allowing water vapour to escape, preventing trapped moisture and substrate degradation.

Solves the Root Cause of Water Damage

Duram S900 is engineered to address the most common and destructive problems caused by water penetration. By creating a hydrophobic zone within the substrate, it effectively:

• Prevents Corrosion: Shields steel reinforcement in concrete from rust-inducing moisture and chlorides.
• Halts Surface Deterioration: Combats friability, binder loss, and powdering of surfaces by keeping them dry.
• Inhibits Biological Growth: Assists in preventing mold, fungus, algae, and bacterial attack by removing their source of life—moisture.
• Reduces Efflorescence: Minimizes the unsightly white salt stains (efflorescence) by blocking the water that dissolves and transports salts to the surface.

Built for Performance and Aesthetics

Specifically formulated to withstand the high alkalinity of new concrete and lime-based mortars, Duram S900 provides long-lasting protection from day one. It dries to a perfectly clear, non-glossy finish, preserving the natural look and texture of your concrete, brick, sandstone, or render without altering its appearance.

• Will not bridge or seal existing cracks; cracks must be repaired prior to application.
• Requires a sound, stable substrate; it will not adhere to or strengthen unsound, friable surfaces.
• Effectiveness depends on sufficient absorption; highly porous/sandy surfaces may require extensive testing and multiple coats.
• Treated surfaces can become slippery when wet.
