Our climate is changing and this is certainly noticeable in the urban environment. It's raining more often and more heavily, but long periods of drought are also occurring. Rockflow provides sustainable solutions for the collection, infiltration and re-use of rainwater. With an eye on the future, we at Rockflow believe in natural materials based on stone wool.
Percentage of the global population that will live in an urban environment in 2030.
Increase in the number of days of extreme rainfall over the past 100 years.
The absorption capacity of stone wool. Almost its entire volume is available for the absorption of water.
Stonewool is literally made of stone. This material can be found naturally around volcanos, where molten lava is strewn around and settles as thin fibres. ROCKWOOL has imitated and perfected this process, which results in a strong, natural and completely circular material. Stone wool is also extremely effective in absorbing water quickly, whereby it can buffer 95% of its own volume in a very short time. Due to its structure, the product is super strong and retains its shape.
Rockflow forms a sustainable solution for rainwater collection, infiltration and re-use in urban areas.
01
Stone wool is a natural material (made from natural rock) which is produced sustainably by ROCKWOOL. Stone wool is fully recyclable and circular.
02
Rockwool stone wool elements are easy to adapt, without loss of functionality during and after installation, so that any pipes or other obstacles in the ground do not form any hindrance.
03
Rockflow stone wool elements can absorb 95% of their volume in water in in a very short time. This means that almost the entire volume of the elements is available for the collection of water.
04
The stone wool elements can be used for various applications. Infiltrate rain on the spot where it falls, or retain it for optimum use during a drought.
05
Stone wool is not only natural, but also very strong. It also has a high load bearing strength, even when a lot of water is buffered.
In Beverwijk, the Netherlands, a new construction project is not allowed to discharge rainwater via the sewer system. The apartment building on De Brink with 94 sustainable, gasless homes will therefore be equipped with a Rockflow water buffer under the building and a water-buffering roof with stone wool elements under a sedum cover.
Platform 'Amsterdam Rainproof' has the aim of making Amsterdam resistant to the increasingly frequent downpours. The sustainable solution Rockflow helps Amsterdam to combat flooded streets and basements due to intense rainfall.
The playing field in Heel was located in a groundwater protection area, which presented a lot of challenge. Rockflow offered the solution here because a lot of storage can be created while you remain fairly close to ground level.
Rockflow water storage and infiltration system is applied in the municipality of Maasgouw (Limburg) under residential streets as a rainwater sewer. The municipality had previously successfully installed the Rockflow buffer system under playgrounds and parking lots.
Sweden also suffers with increasingly extreme rainfall in the summer. Hedemora, a town in a hilly landscape where rainwater has always found a natural way, is the first municipality in Sweden where the increasing flooding is counteracted with a Rockflow rainwater buffer.
Flooding occurs everywhere, including in schoolyards. In Schimmert, the problems with flooding in the schoolyard of the 'Kirkeveldsje' have been solved by applying Rockflow.
Rockflow tackled a too deep, too steep and difficult to maintain swale in Heel. Water that does not infiltrate quickly enough is led via the gully directly to the buffer from where it infiltrates into the subsoil.
Located in Limburg (NL), the village of Oirsbeek in the municipality of Schinnen is vulnerable to flooding due to large amounts of rainwater coming down from the steep slopes that surround it.
An enormous 'sponge' has been installed in Zevenaar for the large-scale urban renewal: the Rockflow water management system. This underground system collects rainwater and slowly returns it to the environment.
