1. Durability & Corrosion Resistance

  • FRP Tanks: Made from corrosion-resistant fiberglass reinforced plastic, they are unaffected by water, chemicals, or UV. No risk of rust or spalling.

  • Concrete Tanks: Susceptible to cracking, leakage, and steel corrosion over time, especially in high-salinity or coastal environments. Require internal coating for added protection.



2. Hygiene & Water Quality

  • FRP Tanks: The smooth inner surface prevents algae growth and sediment buildup. GTOFRP™ tanks use food-grade, non-toxic materials approved for potable water.

  • Concrete Tanks: Porous surfaces can harbor bacteria and are harder to clean. Regular disinfection is needed.



3. Installation & Mobility

  • FRP Tanks: Delivered as lightweight panels that are easy to transport and assemble on-site. No large cranes or curing time required.

  • Concrete Tanks: Require heavy machinery, skilled labor, and a long curing period. Once built, they are fixed permanently in place.



4. Maintenance & Repairs

  • FRP Tanks: Minimal maintenance. If damaged, individual panels can be replaced easily.

  • Concrete Tanks: Cracks may require expensive patching, lining replacement, or full tank reconstruction.



5. Lifespan

  • FRP Tanks: 30+ years when properly installed and maintained. GTOFRP™ tanks come with long-term structural guarantees.

  • Concrete Tanks: 40–60 years but with significantly more upkeep and risk of internal deterioration.



6. Customization & Scalability

  • FRP Tanks: Modular design allows easy resizing, relocation, or shape adjustment to fit different site constraints.

  • Concrete Tanks: Fixed dimensions and location once constructed. Expansion is complex and costly.
