Stronger, lighter and more sustainable: stackable blocks for the future

Neptunus Structures is an internationally leading player in demountable buildings and event tents. For many years, they used only wooden stacking blocks at their construction and assembly sites for tents. Practical in use, but less ideal in reality: sensitive to weather conditions, frequently needing replacement, and never exactly the same size. That could be smarter, stronger, and more sustainable!

The facet ID "0", used to filter the grid "wpgb-content", is not valid.

Sustainable plastic stacking blocks with maximum load capacity

The challenge was clear: how do we create a stacking block that can withstand intensive use and all weather conditions, without compromising on strength and load capacity?

The design proved to be essential. A solid plastic block would be unnecessarily heavy, expensive, and material-intensive. That’s why we opted for a smartly engineered design with ribbing: an internal structure that delivers maximum strength while using minimal material.

In close collaboration with Neptunus Structures, we explored the optimal material combination to guarantee strength, stiffness, and durability. Every detail — from wall thickness to rib structure — was carefully calculated to ensure the product can easily withstand the substantial forces generated by tent structures.

Precision engineering with our partner in Kessel

The most technically challenging part? In tent construction, there are clear guidelines for wood — but not for plastics. This meant that all strength calculations had to be extremely precise and fully substantiated.

Together with Neptunus Structures, we went through the entire process: design, engineering, testing, and optimization, strictly following the Stage-Gate model to ensure that no risk was overlooked. Thanks to this careful approach, Neptunus Structures could move forward to production and practical use with confidence.

And the fact that we only had to knock on a few doors further down the hall at our partner in Kessel for consultation? That made the collaboration not only efficient, but also particularly enjoyable.

The result: lighter, stronger and more sustainable

The new plastic stacking block delivers everything Neptunus Structures hoped for — and more:

  • Long-lasting, without being sensitive to weather conditions;
  • Consistent dimensions, something that is difficult to achieve with wood;
  • Lighter than wood, making work on site more ergonomic, safer and more comfortable;
  • Improved handling and easier placement;
  • Highly reusable, resulting in direct cost savings and a more sustainable supply chain.

The result? A smart solution that combines future-proof design, safety and efficiency.

The strength of this collaboration lies in the short lines of communication and technical expertise. Because we are practically neighbors, we were able to move quickly and jointly develop a product that perfectly suits our teams during tent construction.
