Why Rockflow?

With custom solutions, we prevent flooding and create a healthy water balance in the city

Why water storage with Rockflow?

The healthy city of tomorrow needs not only good infrastructure for people but also for water. For less urban flooding, cleaner water, more greenery, and a better quality of life. The infiltration buffers of ROCKWOOL Rainwater Systems take up hardly any space above ground and create a lot of space underground for water storage. A modern solution for the modern city that also contributes to cleaner groundwater and surface water.

Rockflow has been successfully applied in over 300 locations. Check out our case studies:

Preventing urbanflooding

Rainwater capture

Even in densely built cities, you can cleverly create underground space for rain. With an underground Rockflow stormwater system made of circular stone wool, you effectively capture rainwater and then return it to the ground through natural infiltration.

Cleaner groundwater and surface water

Filtering runoff rainwater

The natural environment and the quality of life in cities benefit from clean groundwater and surface water. A buffer of ROCKWOOL Rainwater Systems retains much of the potential pollution. Thus, the water that infiltrates the ground is much cleaner. The stone wool system itself can be cleaned in no time.

Protecting the natural water cycle

Infiltrating rainwater

A natural water cycle is essential to counteract desiccation. However, urban paving prevents water from being absorbed into the soil. Instead, it flows away via the stormwater sewer to prevent waterlogging during heavy rainfall. ROCKWOOL Rainwater Systems offers a solution that takes up no space above ground and creates sufficient space underground for water infiltration.
