Most traditional modular water tanks rely on internal tie-rods. But why are they necessary—and are they still the best solution?
What Are Tie-Rods?
Tie-rods are internal metal supports used to:
- Prevent tank walls from bulging
- Maintain structural stability under pressure
The Problem with Tie-Rods
While effective, they introduce several issues:
- Difficult cleaning
- Corrosion risk
- Stress concentration at connection points
A Better Alternative
Modern designs use structural optimization instead of internal supports.
Arc-ribbed panels distribute pressure across the surface, making tie-rods unnecessary.
LeAqua eliminates tie-rods through advanced structural design,And we used finite element analysis to prove the feasibility of eliminating the internal rods.

FAQ
Why do water tanks need tie-rods?
They are used to resist outward pressure from stored water.
Are tie-rods still necessary?
Not in modern arc-ribbed designs, which achieve strength through geometry.
