Best Waterproofing Techniques for Overhead Water Tanks
1. Cementitious Waterproofing
A popular method where a cement-based waterproofing slurry is applied to the internal and external surfaces of tanks.
Advantages:
- Cost-effective
- Durable and strong adhesion

- Long-lasting performance
3. Polyurethane (PU) Waterproofing
A highly flexible and elastic coating that prevents cracks and leakage even under thermal expansion.
Why Choose It?
