Rockflow® fills up rapidly with water and is ready for the next peak rainfall within 24 hours
It's becoming an increasingly common picture: a cloudburst occurs, and the streets are flooded. The sewer system simply can't cope. Eventually, the water is drained via the sewer, but by then, damage, nuisance, and water pollution may have already occurred.
With solutions from ROCKWOOL Rainwater Systems, this image becomes a thing of the past. Even in densely built cities, you can cleverly create space for rain underground.
Rockflow stone wool elements have up to 95% free space. This space is available for the rapid capture of rainwater. In a system, water is supplied from below. The buffer fills with water from the bottom, and the air escapes through the vent at the top.
The speed of collecting water is determined by the size of the system, the water pressure, and the number of available inlets. Normally, the design accounts for the system to be filled in a maximum of 15 minutes.
The inlet channels provide for the rapid capture of rainwater into the Rockflow system.

Also in urban areas, a natural water cycle is essential to combat 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.
Creating more space for greenery, parks, and natural infiltration is not always possible in urban areas. The available space is sorely needed for other purposes. ROCKWOOL Rainwater Systems offers a solution that takes up no space above ground and creates sufficient space underground for water infiltration. For a vibrant, green city with a natural water cycle.
| Rainwater infiltrates the soil within 24 hoursWith solutions from ROCKWOOL Rainwater Systems, water is returned to the ground. Rainwater is not carried away but is quickly captured on-site in an underground buffer. Within 24 hours, the water gradually infiltrates the soil.

 | Protecting the local water balanceIf rain can infiltrate the ground in built-up areas, more water is available for trees and plants in the immediate vicinity. This promotes biodiversity, shade, and cooling, and keeps the city a pleasant, livable place in hot summers. |
