“AquaBOX” – an innovative modular tank for underground installation

6 August 2025

Company «TechPolymer» has launched active production of modular underground tanks «AquaBOX» (СТО 56910145-053-2022), made of mineral-filled polypropylene. This solution combines practicality, cost-effectiveness and ease of installation, offering an alternative to traditional fibreglass and polyethylene tanks.

Key advantages of «AquaBOX»:

1. Optimised logistics and storage

  • Compact transportation: the modules are transported disassembled, allowing two 60 m³ tanks to be loaded into a standard European truck.

  • Delivery savings: no special transport for oversized cargo is required, reducing costs.

  • Convenient storage: the modules can be stacked, taking up minimal warehouse space.

2. Fast production and convenient installation

  • High production speed: up to 400 m³ per day, significantly faster than manufacturing fibreglass equivalents.

  • Easy assembly: each module weighs 125 kg, allowing installation using a crane truck or forklift without heavy equipment.

  • Configuration flexibility: the tank capacity can be easily increased in multiples of 5 m³ depending on project requirements.

3. Reliability and environmental performance

  • Repairability: if necessary, a damaged module can be replaced without dismantling the entire structure.

  • Environmentally friendly material: polypropylene can be recycled, unlike fibreglass.

  • Production safety: the manufacturing process does not produce toxic emissions.

4. Strength and leak-tightness

  • Installation depth: up to 3 m, meeting most technical requirements.

  • Joint leak-tightness: ensured by gaskets or sealant, while bolted connections ensure structural stability.

Installation process

  1. Base preparation.

  2. Installing the modules to form rings.

  3. Tightening the rings and securing them with bolts.

  4. Sealing the joints.
