Change we bring about together

Be inspired by the Rockflow ambassadors

We design our living environment together. And it's time for a fresh perspective. Today's cities house more people than ever before, which means we need to look smarter and more efficiently at what we do with water in the city.

In more and more places, municipalities, companies, and individuals take the initiative to return rainwater to the ground through infiltration. This saves costs, is good for the environment and the livability of the city, and prevents overloading at the water treatment plants.

Work with us on fresh solutions for collecting, filtering, and infiltrating rainwater. Together we make cities climate-resilient!

Rockflow ambassadors speak out

Hear it not from us, but from satisfied clients, customers, and users.

Ruben Swier, KWS

"Our experience is that Rockflow is quite simple to install, since the instructions and guidance from ROCKWOOL are clear and straightforward. The speed of construction is also high."

Project: Amsterdam Nieuwzijds Voorburgwal

Rutger Traag, Municipality of Duiven (NL)

"The system remains intact in the ground for years without the material being affected. These qualities were decisive for us to choose Rockflow. The swales retain the function of water buffering, they remain neatly maintained, and they are safe for children.”

Torben Tijms, Waternet

"Amsterdam has made climate adaptation a high priority on its agenda. What you actually want to do is create a sort of toolkit with measures and systems that are ready to be deployed if you want to take action in the city, so that you know in advance which measures you can implement when you are running a project.”

Ronald Pluijmakers, Royal Haskoning DHV

""When I heard the story about Rockflow, I was immediately convinced of its benefits and saw that it was a perfect fit for my primary school project in Schimmert. In close collaboration with all parties involved, the pilot project was then prepared and ultimately successfully executed."

Lowie Eijkelhardt, Maasgouw Municipality

“The high absorption capacity of Rockflow also means that less material is needed to achieve the desired buffer volume. Compared to lava crates, that's more than a factor of 2. This means that less than half of the soil needs to be excavated with Rockflow.”

Project: Maasbracht

Joop Schagen, advisor for area development and citizen participation

"The infiltration buffer is a practical and sustainable solution for the current water management issues that municipalities are increasingly facing. It has high water permeability and uptake speed, and it can absorb up to 95% of its own volume in water.”
