Every year, the Cobouw Awards are presented, with the aim of rewarding inspiring frontrunners and smart solutions that contribute to a future-proof construction sector. In the Innovation category, our JustNimbus system is one of the three finalists — and we are incredibly proud of that! On 27 November, the winners will be announced during Cobouw Live, and of course we will be there. Read more about the nominations here.

Why JustNimbus?

With an impending drinking water shortage and increasing pressure on the sewer system, we must rethink how we use water. The JustNimbus rainwater system makes it possible to buffer rainwater and use it for toilet flushing, garden irrigation, and washing machines. This nomination confirms that our innovation can make an impact in both the civil engineering and housing sectors. In doing so, we save valuable drinking water and help relieve the pressure on the sewer system.

Scaling up and making an impact

If the pilot proves successful, the partners aim to scale up the use of the material. “For example, on the Zuid-West 380 kV East project, where we’re working on a new high-voltage connection between Rilland and Tilburg,” says Richard. “We’re already applying circular principles there, like reusing sand. This would fit in perfectly.”

“After this testing phase, Joosten Groep will continue developing a biobased product line tailored to the needs of various stakeholders,” Marco confirms. “And beyond that, this product could be used in many other types of temporary construction. It’s definitely worth exploring.”

And if it doesn’t work out? “Then we’ve still learned something,” says Richard. “Maybe we need to adjust the material or try a different variant. But the fact that we’re willing to take this step says everything about how we want to build.”

Details make the difference

It might seem like a small detail—a piece of fabric beneath a construction road—but the impact is significant. “If we get this right, we save on waste, emissions, and labor,” says Richard. “And we leave the soil in better condition than we found it. That’s what it’s all about.”

Marco adds: “Jogetex HV could very well be the next milestone—not just in how we build, but in how we think about the life cycle of our building materials. We’re shifting from ‘dispose or recycle after use’ to ‘return to nature.’ That’s a fundamental change.”
