Characteristics of HydroEarth
HydroEarth components in an aqueous solution with surface tension less than half that of water deeply penetrate concrete’s capillary pores and voids.
These components react with the free alkalis in concrete (mainly free lime) and highly reactive silica in the aggregate (amorphous silica). Gradually, these reactions form insoluble inorganic compounds within the pores and voids, filling them and preventing the absorption of water by the concrete itself.
Unlike organic water repellents or resin coatings that merely cover the surface, HydroEarth forms a breathable waterproof layer.
Prevention of Carbonation and Neutralization of Concrete:Carbonation (neutralization) is a major cause of concrete deterioration, primarily resulting from the reaction of free alkalis in the concrete with carbon dioxide and water, which accelerates the neutralization process.
By stopping water absorption and converting free alkalis in the substrate into stable substances, HydroEarth prevents carbonation. Moreover, when applied (impregnated) to already-carbonated concrete, the highly alkaline HydroEarth restores and improves the alkalinity of the concrete.
When HydroEarth is applied, it reacts with the free alkalis inside the concrete structure, generating water-insoluble inorganic crystals in the voids. These extremely stable crystals strongly bond within the substrate and densify the surface, thereby strengthening the surface layer and forming a permanent breathable water-resistant barrier without altering the texture of the concrete.
Prevention of Structural Deterioration
By forming a water-resistant layer on the inner surface of the structure, HydroEarth prevents water penetration, which in turn prevents the leaching of alkalis inherent in the structure. This enhances the durability of the structure.
(Prevention of efflorescence: Suitable for exposed concrete, mortar, tile joints, stone, etc.)
Pollution Prevention
HydroEarth prevents contaminants dissolved in water from penetrating into the structure.
(Suitable for preventing dirt and mold on surfaces such as exposed concrete, mortar, tile joints, stone, brick, and plaster.)
Strengthening of Surface Layers
The formation of hard inorganic crystals that bond firmly to the voids in the structure improves abrasion resistance and creates a dust-proof effect.
(Suitable for open corridors and ground floors.)
Prevention of Leakage
For minor cracks such as hairline cracks, HydroEarth’s ability to block water infiltration due to the surface tension of water prevents leakage and provides waterproofing.
(Suitable for external walls, drainage channels, open corridors, balconies, ground floors, and tiled walls.)
