RockSeal C2 is a high-performance crystalline waterproofing coating developed to provide long-term protection against water penetration in concrete and mortar structures. The product contains moisture-activated additives that act as catalysts, forming water-insoluble crystalline micro-structures deep inside the capillaries and pores of concrete. Unlike surface membrane systems, RockSeal C2 does not rely on film formation. Its deep penetrative crystalline action permanently seals pores and micro-cracks, making it highly effective even under negative hydrostatic pressure. When exposed to water, the crystalline process is reactivated, offering continuous self-sealing protection throughout the service life of the structure. RockSeal C2 ensures excellent water tightness while protecting concrete and steel reinforcement from water-borne contaminants. It is non-toxic, non-tainting, and suitable for use in water-retaining as well as water-excluding structures. The system is ideal for applications such as water tanks, reservoirs, swimming pools, basements, tunnels, foundations, retaining walls, lift shafts, canals, dams, bridge decks, jetties, and concrete pipes. RockSeal C2 can be applied to both new and existing structures and is compatible with brush or spray application methods. With its proven crystalline technology, RockSeal C2 provides a durable, reliable, and permanent waterproofing solution for critical concrete structures.
