Our mission: we build water conscious sponge cities

using the power of stone wool

At ROCKWOOL Rainwater Systems, we believe in sponge cities; cities that absorb rainwater and put this valuable resource to good use. By fostering a healthy urban water balance, sponge cities are better adapted to the effects of climate change, such as heavy rainfall and excessive heat.

Powered by Rockflow® stone wool, we create sustainable, durable solutions for stormwater storage and infiltration, delayed discharge, treatment and reuse, helping to build future ready sponge cities.

Our ambition: Prevent flooding, harvest valuable rainwater – and safeguard water quality

Our stone wool solutions capture, filter and bring valuable rainwater to good use. And thereby contribute to a healhier water balance and cleaner water tables in cities.

Our approach: Stronger together!

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

We are convinced that stone wool solutions can contribute to healthy water systems in our cities.

We invite you to work with us on fresh solutions for collecting, filtering, and infiltrating rainwater. Together we make cities climate-resilient!
