General Information About Pool Construction Types
In this section, you will find comprehensive information about the main types of pool construction, their technical differences, and the potential problems or disadvantages that may occur over time.
Choosing the right construction method is not only a matter of design — it directly affects the durability, waterproofing performance, and long-term reliability of your pool.
Our goal is to help you avoid common pitfalls and select the solution that best matches your property, usage needs, and investment expectations.
THERMAL BLOK – The Isothermal Pool by Aegean Pools
The THERMAL BLOK system by Aegean Pools represents the pinnacle of prefabricated pool engineering in Greece.
It is made of high-density EPS insulation panels, filled on-site with reinforced concrete, combining structural strength with integrated thermal insulation.
Key advantages include:
-
Constant water temperature, up to +3°C higher than conventional pools
-
Fully integrated plumbing within the walls for maximum safety
-
No external braces and reduced excavation space
-
Compatible with all types of finishes (Liner, AEGEAN SLIM, tiles)
-
Custom-built to any dimension and depth
-
Resistant to corrosion and deformation
-
Life time warranty
The THERMAL BLOK pool is the ideal choice for both private residences and professional properties (Airbnb, hotels), offering a rare combination of energy efficiency, solid construction, and luxurious design.
Metal Prefabricated Pools
Metal panel pools consist of steel walls assembled on-site, offering quick installation and low initial cost.
However, their long-term durability depends heavily on the quality of corrosion protection.
Prolonged exposure to moisture and pool chemicals can lead to oxidation, material fatigue, and —in advanced stages— complete structural failure or wall collapse.
Although regular maintenance and waterproofing may delay these effects, metal pools generally lack the structural stability and lifespan of concrete or THERMAL BLOK system.
Fiberglass (Polyester) Pools
Fiberglass pools are made from a single molded polyester shell, which is placed directly into the excavation.
While the installation process is fast and convenient, these pools come with notable limitations in terms of longevity and maintenance.
A major issue is osmosis — the formation of bubbles and blisters under the surface due to a chemical reaction between water and resin.
Over time, this leads to discoloration, surface damage, and loss of waterproof integrity.
Additionally, fiberglass shells lack the structural rigidity and pressure resistance of concrete or reinforced THERMAL BLOK system.
Concrete Pools
Concrete remains the most robust and versatile construction method for swimming pools.
It allows unlimited design freedom, custom dimensions, and compatibility with any type of interior finish.
When properly designed and waterproofed by skilled professionals, a concrete pool offers exceptional durability, long-term reliability, and timeless elegance — making it an investment that truly lasts.
✨ In Summary
Choosing the right pool type is a strategic decision that defines not only the lifespan of your construction but also the overall experience of pool ownership.
At Aegean Pools, we provide expert guidance to help you select a solution that ensures technical excellence, thermal efficiency, and refined aesthetics for years to come.
