Specs of HydroTherm

The components of HydroTherm in a solution with surface tension less than half that of water penetrate more deeply than water itself, moving through the capillary water gaps and voids in concrete and stone, achieving deep penetration.

Once penetrated, HydroTherm reacts with the free alkalis (primarily free lime) in concrete and stone, as well as with the highly reactive silica (amorphous silica) in the concrete aggregate. Over time, it transforms into an insoluble inorganic compound within the water gaps and voids.

The inorganic compound formed is more stable than before the reaction, filling the water gaps and voids. It starts to reinforce the substrate approximately four days after application.

The insoluble inorganic compound, which fills the water gaps and voids and densifies the structure, impedes the absorption of water by the concrete and stone itself. Unlike organic water repellents or resin coatings that are merely applied to the surface, it forms a permanent, breathable waterproof layer.

Neutralization, a major cause of concrete deterioration, is primarily due to the carbonation or acidification of free alkalis in the concrete, a process that is mainly accelerated by carbon dioxide and water. By stopping water absorption and converting the free alkalis in the substrate into stable substances, neutralization is prevented. When high-alkaline HydroTherm is applied to concrete that has already undergone neutralization, the alkalinity is restored.

Concrete and stone treated with HydroTherm are protected from water penetration by a stable and dense protective layer. This not only prevents neutralization and alkali-aggregate reactions but also guards against salt damage and frost damage, significantly enhancing the durability and stability of concrete structures.
