Rainwater flooding

Smart, sustainable water management of rainwater flooding

Prevent rainwater flooding with smart water management

Our climate is changing. According to the KNMI, we must get used to wetter winters and heavier showers in the spring and autumn. We're seeing this already: it rains harder and more often, and all that rain has to go somewhere. But the Dutch sewage system is mostly outdated. What happens when a lot of rain falls in a short time? The system often cannot cope with such a large quantity of water. This has serious consequences: from flooded cellars and water on the roads to closed tunnels and highly polluted ponds.

Stone wool has an absorption capacity of at least 95%. Almost its entire volume is available for the absorption of water.

Rockflow requires an installation depth of just 38 cm.

Is more rain forecast? Rockflow's buffer capacity is fully available to collect new downpours after just 24 hours.

The benefits of Rockflow

Stone wool is sustainable, surprisingly versatile and remarkably strong. With a buffering capacity of 95%, Rockflow's stone wool applications offer an innovative, very quick and efficient method of water storage. Even during peak downpours. A lot of rain in a very short time? This is when the hugely absorbent capacity of the stone wool elements come into their own. And by delaying the discharge of the excess rainwater, overloading is avoided, preventing flooding on the roads. In doing so, Rockflow is keeping our country moving and ensuring it is future-proof.

Rockflow infiltration systems

Parks and swales

In residential areas, a swale must be relatively deep to function properly, which can lead to unsafe situations and difficult maintenance. With Rockflow stone wool elements, a swale can be made shallower, without loss of capacity and the green appearance.

Squares and car parks

Urban areas are largely paved by roads, squares and parking places. The risk of flooding is greatest in these paved areas. Rockflow limits the risk of flooding on squares and parking spaces, even during extreme rainfall.

Alongside and beneath the road

Rainwater that falls on paved surfaces, such as on roads, cannot sink into the ground, which can cause serious flooding. The Rockflow infiltration system, made up of stone wool elements, can be used to buffer water and slowly release it into the ground.
