Provides integral waterproofing protection within the concrete matrix.

Here’s a question for every engineer in Pakistan:

Why do we pour concrete, wait for it to cure and then only then start worrying about waterproofing?

Membranes applied after construction are expensive. They need skilled labor. They can be damaged during backfilling. UV destroys them over time. And they have a finite lifespan 10 to 15 years before replacement.

But what if the waterproofing was already there? What if every cubic meter that came out of the truck was already watertight from the inside?

BETOCRETE®-CP350-CI makes this possible. It is a powder admixture added during batching that Provides long-term integral waterproofing protection, corrosion-resistant material.

For betocrete waterproofing in Pakistan, this is the future.

What Is BETOCRETE®-CP350-CI?

BETOCRETE®-CP350-CI is a grey powder a concrete admixture that combines two powerful technologies:

  1. Crystalline Waterproofing

Active chemicals react with water and cement byproducts to form insoluble crystals that block concrete’s capillary pores. These crystals become part of the concrete matrix permanent, insoluble and self-healing.

2. Corrosion Inhibition
 Compounds that protect steel reinforcement from rust, even if chlorides eventually penetrate the concrete.

Packaging:

· 20 kg bags for batching plants.

· 3 kg water-soluble bags for precise mixer truck dosing.

How It Works

The Crystalline Reaction

When water contacts cement, hydration produces calcium hydroxide and other byproducts. BETOCRETE-CP350-CI’s active chemicals react with these byproducts and with any moisture that later enters the concrete to form long, needle-like crystals.

Crystalline growth helps reduce permeability by blocking capillary pores and micro voids. They are insoluble. They become part of the concrete matrix.

And they are permanently active. If new cracks form later (up to 0.4 mm), moisture triggers new crystal growth that seals them automatically.

Corrosion Inhibition

Even waterproof concrete can crack. When that happens, water and chlorides can reach the reinforcement. The corrosion inhibitor:

· Migrates to the steel surface.

· Forms a protective molecular layer.

· Significantly reduces corrosion rate.

This dual action makes it ideal for aggressive environments.

Applications Across Pakistan

Coastal Karachi

Chlorides from sea air are the #1 enemy of reinforced concrete. BETOCRETE-CP350-CI reduces chloride migration and protects steel extending service life dramatically.

Lahore Basements and Foundations

When groundwater is present, integral waterproofing eliminates external membranes. No membrane means no future replacement. No replacement means lower lifetime cost.

Water and Wastewater Structures

Certified for drinking water. Use in:

· Potable water tanks.

· Reservoirs.

· Sewage treatment plants.

· Swimming pools.

Northern Infrastructure

Bridges, tunnels and retaining walls in Murree, Gilgit and Skardu face freeze-thaw cycles that destroy ordinary concrete. BETOCRETE-CP350-CI improves frost resistance and heals cracks.

Industrial Floors

Factories and warehouses need concrete that resists water and chemical penetration. Integral protection can’t be damaged by forklifts or spills.

Important Restrictions

Prohibited Cement Types

CEM III/B and CEM III/C cements are prohibited. Always verify cement type.

Fly Ash Limitations

The TDS states: “Lignite fly ash is only of limited suitability.” Conduct preliminary testing.

Setting Time

In rare cases, BETOCRETE-CP350-CI can influence solidification. If adjustment is needed, RUXOLITH-T5 (VZ) is available.

Surface Crystals — Normal and Expected

The TDS notes: “BETOCRETE-CP350-CI modified concretes may have crystals on the surface.”

This is not a defect. It indicates the crystalline reaction is working. Crystals can be brushed off they don’t affect performance.

Frequently Asked Questions

Q: Is BETOCRETE-CP350-CI a surface coating?

No. It is an integral admixture. Protection is throughout the concrete, not just on the surface.

Q: Can it be used for roof waterproofing?

For new construction, yes. For existing leaking roofs, topical solutions like AQUAFIN-IC are more appropriate.

Q: How long does protection last?

As long as the concrete lasts. Crystalline chemicals are permanently active. When new cracks form, they reactivate.

Q: Is it safe for drinking water?

Yes. DVGW W-347 and W-270 certified.

Q: How should I store it?

Cool, dry, protected from sunlight. Shelf life: 12 months.

Conclusion

BETOCRETE®-CP350-CI changes the waterproofing conversation entirely. Instead of asking “what membrane should we apply after construction?” it asks “why not build the protection in from the start?”

For coastal Karachi, for waterlogged Lahore, for the freeze-thaw cycles of the north this admixture offers a simpler, more durable, more cost-effective approach.

One addition during batching. Permanent protection for the life of the structure.
