1. repair methodology
Due to the depth of frost damage, surface repair is insufficient. We suggest aggressive mechanical treatment to expose "healthy" aggregate, followed by chemical impregnation.
Machining
Removal of weak, frosted top layer (milky, loose fractions) using, for example, Bush Hammer heads or milling.
Spot repairs
Repair of cavities, expansion joints, cracks, reinforcement if exposed, etc.
Giving the pavement the right texture
Achieve a safe non-slip texture, such as light sanding with Bush Hammer heads.
Lithium Impregnation
Application C² Hard™ and C² Salt Hard+™ For hardening and chemical protection.
2. increase in abrasion resistance
The key problem of the current floor is peeling and dusting. Application of the product C² Hard™ causes chemical modification of the concrete structure. Independent tests (ASTM C1803) have shown a dramatic increase in resistance to mechanical abrasion.

3. advantage of Lithium Technology
Why do we suggest C² Hard (Lithium Silicate) instead of cheaper sodium hardeners? Lithium, thanks to its smaller molecule, penetrates deeper and does not cause the risk of ASR reaction, which is critical when repairing damaged concrete.
Speed of Response
Full operation possible as early as 1 hour after drying.
No ASR Response.
Safe for older concretes - does not cause alkaline swelling.
Deep Penetration
Declared penetration depth ≥ 10mm (according to DWU).
4 Winter Protection: C² Salt Hard+™
As the pavement has become frozen, it is necessary to apply a "Protective Shield." The C² Salt Hard+ product introduces a hydrophobic and chloride barrier. The chart below simulates the durability of the pavement through freeze/thaw cycles.
