Duram S900 – 4L or 15L

Duram S900 is a clear, high pH, deep penetrating siloxane waterproofing solution. It penetrates in to the tissue of porous substrates and creates a waterproofing barrier below the surface preventing the ingress of water. S900 is an effective waterproofing solution and stops leaks without lifting tiles or changing the overall appearance of the surface. This product also solves the problems associated with water penetration such as corrosion of steel reinforcement, friability and binder loss of surfaces, fungal and bacteria attack and degradation due to carbon dioxide permeability. Duram S900 is capable of withstanding high pH conditions such as found in new concrete and lime based mortars and bricks. S900 still allows the diffusion of vapors or ‘breathing’ ability of the substrate.
