When shopping for a water tank you will find plastic (polyethylene) tanks everywhere, with tempting prices and low weight. Before you decide, let us compare them with reinforced concrete tanks on the points that really matter.
1. Lifespan
A reinforced concrete tank built under engineering supervision and properly waterproofed lasts a very long time, and ours carry a 10-year warranty. Plastic tanks have a shorter life, especially when exposed to the sun.
2. Water temperature in summer
Thin plastic walls let water heat up quickly under the Saudi sun. Thick concrete walls insulate against heat, keeping water much cooler, especially in an underground tank.
3. Capacity
Plastic tanks usually come in small sizes, so large capacity means installing several. A single concrete tank from us goes up to 29 m³, or 29,000 litres.
4. Strength
Reinforced concrete withstands soil pressure, loads and impacts. Plastic can deform or crack under pressure or impact and is not suited to underground use without special preparation.
5. The real cost
Plastic is cheaper upfront, but factoring in its shorter life, the need for several tanks for large capacities, and replacement after a few years, concrete is usually more economical in the long run. Compare our concrete tank prices.
Summary
| Criteria | Reinforced concrete | Plastic |
|---|---|---|
| Lifespan | Very long | Shorter |
| Water temperature in summer | Cooler | Heats up quickly |
| Capacity per tank | Up to 29 m³ | Usually small |
| Underground use | Yes, with waterproofing | Limited |
| Sun exposure | Not affected | Degrades over time |
| Upfront price | Higher | Lower |
If you want a tank that lasts, keeps water cool and holds a lot, concrete is the choice. You can also compare concrete and fibreglass.
