BC Crysto Proof is a high-performance crystalline admixture in powder form, formulated to provide integral waterproofing of concrete.

Mechanism of action and properties:

Chemical reaction: When added to fresh concrete, a chemical reaction begins that generates insoluble and needle-shaped crystals within the concrete matrix.

Blocking water pathways: These crystals fill pores, voids, and microcracks, effectively preventing the passage of water even under high hydrostatic pressure.

Long-term protection: The additive remains inert until moisture reactivates it, enabling long-term cracking and enhancing the durability of the concrete.

2. Key Features & Benefits:

• Permanent integral waterproofing

• Seals capillaries, pores, and microcracks up to 0.4 mm

• Effective against both positive and negative water pressure

• Enhances concrete durability and lifespan

• Resistance to chlorides, sulfates, carbonation, and biological growth

• Withstands freeze-thaw cycles and de-icing salts

• Reactivates in the presence of moisture

• Reduces permeability and maintenance requirements

3. Areas of Application:

• Basement structures and underground concrete

• Water tanks, reservoirs, swimming pools, and concrete basins
