Self-Healing Waterproof Coating That Repairs Cracks Upon Contact with Water?

Have you experienced this? After a few years in a new home, fine cracks appear on walls or roofs, leading to leaks during rainy days—repeated repairs still fail to solve the problem.

Worry no more! Meet the revolutionary cementitious capillary crystalline waterproofing material, a self-healing solution that automatically repairs cracks when exposed to water, ensuring long-lasting waterproofing performance.

Say goodbye to endless repairs. This material acts as a "self-repairing shield" for your property.

1. Self-Healing Magic: Simple Science, Powerful Results

How does it work?

The secret lies in its formulation:

Core Components: Cement, active silica, and a proprietary active compound (the "guardians" of waterproofing).

Mechanism: When water penetrates concrete, these "guardians" migrate into micro-pores and react with cement hydration products, forming dendritic crystalline structures that fill gaps and seal pores.

Self-Healing Power: Even if new cracks (up to 0.4mm wide) form later, water reactivates the compounds, regenerating crystals to seal the damage—like giving concrete a "self-strengthening" ability.

2. Two Key Advantages for Worry-Free Waterproofing

High-Pressure Resistance & Leak Prevention 
Penetrates 5mm+ into concrete to form a dense waterproof layer.
Withstands 120-meter water depth (equivalent to a 20-story building height).
Ideal for underground parking garages, reservoirs, tunnels—any high-pressure environment.

Rigid-Flexible Integration with Concrete
Not just a surface coating—it bonds deeply with concrete for unmatched adhesion.
Resists weathering, UV exposure, and thermal cycles (no cracking in winter, no softening in summer).

3. Versatile Applications: Where Can It Be Used?

Residential: Basements, kitchens, bathrooms, roofs, balconies.
Municipal: Tunnels, culverts, bridges, dams.
Industrial: Water treatment plants, storage tanks.

In short: Perfect for all cementitious surfaces—prevents leaks and repairs existing damage.
