Rockflow for Water Management

Natural solutions for sustaining water resilience

Nederlands / Dansk

The climate is changing: how do we manage extreme rainfall? Not only more rain is falling due to climate change, but rain showers are often more extreme. This means that a lot more water has to be collected and disposed of in a short time. In the countryside this is not usually a problem, but it is more so in the increasingly urbanised environment. More and more land area is being paved or surfaced, as a result of which water can no longer drain into the soil and must be disposed of via the sewer system. That system is not designed to handle extreme rainfall, resulting in flooded streets and basements and other nuisance for residents. The only way to prevent this local flooding is to ensure that water is collected and used or disposed of more quickly and effectively.

This is exactly what Rockflow from Lapinus is designed to do.

The system can be configured in such a way that the volume is fully available again within 24 hours

This is how Rockflow works

Rockflow is an innovative water management system that buffers the rainfall from extreme showers quickly and effectively for it to be subsequently infiltrated into the soil or discharged to the sewer system.

Rockflow benefits

Rockflow is utilised for water nuisance in streets, in squares and in suburbs, when decoupling areas from the sewer system and when (re)designing water retention areas.

01

High drainage and buffer capacity

Rockflow stone wool elements can absorb 95% of their volume in water

within a very short time and have a throughput speed of 200 metres per day.

02

No loss of urban space

The basic material is stone wool, which has all the properties of rock.

Vehicles can park on top of the system without the elements becoming deformed or losing any functionality. All urban functions therefore remain unaffected.

03

Self-filtration

The structure of the stone wool elements filters any contamination from the incoming water, as a result of which the system never becomes clogged.

The system continues to infiltrate from the bottom, even without the use of geotextiles.

04

Flexible

The stone wool elements are easy to adapt, without loss of functionality during and after installation

(without harming quality and performance), so any pipes or other obstacles in the ground do not represent a hindrance.

05

Sustainable

Stone wool is a natural material (made from natural rock)

which is produced sustainably by ROCKWOOL. Stone wool is 100% recyclable.

Sustainability of Rockflow

Stone wool is a natural product made primarily from the volcanic rock basalt. Basalt is a sustainable raw material, sourced directly from our earth and is almost inexhaustible: every year the earth produces 38.000 times more basalt than is used for the production of stone wool by ROCKWOOL.
