Description
Integral Crystalline Waterproofing & Durability Admixture
AC-CRYSTACRETE is a high-performance crystalline admixture that transforms concrete into an impermeable barrier. When exposed to moisture, its proprietary chemicals react with cement hydration products to grow insoluble, needle-like crystals. These crystals permanently seal pores and capillary tracts, providing lifelong protection against water and chemical attack.
Core Advantages
- Self-Healing Technology: Automatically seals hairline cracks up to 0.5mm upon contact with moisture.
- Dual-Pressure Resistance: Withstands extreme hydrostatic pressure from both positive and negative sides via crystalline osmosis.
- Permanent Protection: The crystalline action remains dormant and reactivates whenever water is present, offering “evergreen” waterproofing.
- Corrosion Defense: Chloride-free formula that shields reinforcement from waterborne corrosive agents.
- Standard Compliant: Classified as a Permeability Reducing Admixture for Hydrostatic conditions (PRAH) per ACI-212-3R-10.
Ideal Applications
- Water Infrastructure: Dams, reservoirs, treatment plants (WTP/STP), and swimming pools.
- Underground Structures: Tunnels, basements, foundations, subways, and lift shafts.
- Marine & Civil: Sea defense walls, bridge decks, rigid pavements (PQC), and culverts.
Key Feature: Because it becomes an integral part of the concrete matrix, it cannot be punctured or damaged like surface membranes, making it the ultimate solution for high-durability infrastructure.
