we are rainup, providing you with a selection of products and systems for capturing, storing, and reusing rainwater.
We see rainwater in the urban area as a building block, not a problem. By collecting it where it falls and using it when needed, we create a healthy, climate-resilient living environment. We invite you to think differently about rainwater!

water management & innovation, from the experience and vision of our founder
Rozanne van Vliet, founder of Rainup and managing director of Permavoid, is determined to spread the word about the importance of (rain) water management and inspire people worldwide. From water-storing sports fields at Real Madrid to blue-green roofs in Amsterdam, her international experience and network in the water management industry enables us to develop these for people's homes. We believe that every drop of water counts, whether you store and reuse it under a stadium field, at a train station or under your own dream garden.
permavoid technology
For nearly 25 years, Permavoid has been developing products and systems for reusing (rain) water and optimizing infrastructure in the urban area. From stadiums to city trees, bike paths to roofs. The units are made of high-quality, 100% recycled material. Rainwater is a valuable resource that we should cherish. Rainup by Permavoid is committed to taking the next step: optimizing the environment around our homes.

making a difference, one drop at a time
We believe in giving back to the community and being environmentally conscious. That is why we donate 2% of our sales to a project that helps spread awareness and knowledge about the importance of rainwater. By introducing children to the possibilities and beauty of rainwater through play, we are working towards a resilient future. Join our mission and make a difference, one drop of rainwater at a time.
without our partners, we couldn't do it.
