Water Proofing
PATRAWALA-NS is a mineral-based silica powder (SiO, 98%+) that enhances concrete strength with multiple properties including self-compacting ability, strength enhancement, heat dissipation, prevention of water seepage (leakages), and smooth surface finish. It meets all national and international standards for ready-mix concrete applications.
- High grade Concretes
- Ready Mix Plant (RMC)
- Precast work
- All type of concrete work.
Crack Reduction: PATRAWALA-NS aids in preventing cracks, improving cohesion, and reducing maintenance costs in the long term.
Compressive Strength: Demonstrates compressive strengths ranging from 12.1–14.5 MPa at 2 days, 19.1–23.8 MPa at 7 days, and 34.1–36.9 MPa at 28 days.
Purity: Contains high levels of silica (95% to 99%) compared to regular sand, reducing impurities.
Temperature Reduction: Can reduce temperatures via carbon reduction at 1600°C–2000°C to yield volatile silicon monoxide.
Water Leakage Reduction: Some silica sands absorb moisture better than others, aiding in reducing water leakages.
Time Saving: Offers quick setting time and smooth surface finish, reducing further surface treatment time.
Long Durability: Allows for long-term use, reducing maintenance costs.
Easy Application: Easy to mix in batches as needed.
Eco-Friendly: Contains no fly ash or slag.
The surface should be free from oil, grease, paint, loose plaster or dirt particles.
16% to 18% of water by weight of material
Mix thoroughly using mechanical stirrer for 2-3 minutes
Leave the mix to react for 5-10 minutes before use
The mixture should be thrown while the cement slurry is wet, ensure leveling with the help of tools.
Use between 5° C to 50° C
Curing 2-3 times a day for 7 days
Prevent direct contact with skin and eyes. In case of contact, wash with clean water immediately
