Advanced Integral Waterproofing Technology for Concrete & Cementitious Systems
NOVASTAR™ CCCW-AD cementitious crystalline capillary waterproofing admixture is a high-performance integral waterproofing additive engineered using advanced crystalline growth technology and premium active inorganic compounds.
Designed specifically for concrete waterproofing, cement-based coatings, and premixed mortars, CCCW-AD enhances internal densification by forming permanent needle-like crystals that block capillary pores and microcracks.
Used at 2%–4% of total cementitious materials, CCCW-AD crystalline waterproofing admixture delivers 200–500× improvement in impermeability, dramatically extending the service life of concrete without affecting strength, breathability, or durability. It is widely used as a core raw material for manufacturing cementitious crystalline waterproof coatings and premixed crystalline mortars.
CCCW-AD crystalline waterproofing additive forms long, dense, needle-like crystals that penetrate the concrete matrix.
NOVASTAR™ CCCW-AD integral waterproofing admixture actively responds to moisture and reseals future microcracks.
CCCW-AD crystalline waterproofing powder increases resistance against harsh concrete conditions.
CCCW-AD waterproofing admixture creates a vapor-permeable structure that ensures long-term performance.
Suitable for drinking-water structures, reservoirs, tanks, pools, and municipal works.

NOVASTAR™ CCCW-AD Cementitious Crystalline Capillary Waterproofing Admixture is widely used in major infrastructure projects requiring integral concrete waterproofing and self-sealing crystalline technology:
Crystalline waterproofing for underground structures
High-pressure water resistance for large-scale structures
Permanent protection against groundwater infiltration
Durability enhancement for exposed concrete
Chemical-resistant waterproofing for harsh environments
High chemical resistance for industrial facilities
Potable water-safe crystalline waterproofing
Safe, non-toxic waterproofing for recreational facilities
Integral waterproofing for PC components
| Material | Dosage | Role in Cementitious Waterproofing |
|---|---|---|
| Cement | 64% | Primary binder (Use P.O 42.5 or above for best crystalline reaction) |
| NOVASTAR™ CCCW-AD | 2–4% | Core crystalline catalyst; forms capillary-blocking crystals |
| Quartz Sand | 30% | Filler (60–100 mesh; enhances coating strength) |
| Water–Cement Ratio | 0.3:1 | Optimal for crystalline capillary growth |
This proportion ensures maximum crystalline formation and long-term waterproofing performance

It is an internal waterproofing technology that forms insoluble crystals inside concrete to block pore networks permanently.
No. It typically increases compressive strength due to improved densification.
Typically 2%–4% by weight of cementitious material.
Yes. It can be used together with PCE, RDP, HPMC, defoamers, and most cement additives.
It significantly reduces or eliminates the need for external membranes in many conditions, but design decisions depend on project requirements.
Slight retardation may occur but remains within normal ranges.
