Our contribution to clean groundwater in cities. Ecological products with a water-permeable and purifying effect. Rainwater can seep into the ground via the joint or directly through the stone and partially evaporate again. The products in the proWater range have a general construction type approval (aBG) and are tested and suitable as a system construction type for groundwater protection. Plan and build with an average runoff coefficient ψm = 0.0 and with maximum safety.
In view of completely overloaded watercourses and canals and the resulting flooding, the maxim today is: rainwater should no longer be collected and drained away in canal networks, but should seep away and evaporate where it falls. In this context, water-permeable and water-storing concrete paving has proved so successful that it is being promoted in many places.
Decentralized rainwater management and especially surface infiltration have long been considered state of the art due to the legal situation and municipal decision-making. In all areas, water-permeable construction with concrete surface systems has proven to be an ecologically sensible rainwater treatment with filtering, evaporation and infiltration of surface water and precipitation. Ecological surface systems minimize runoff peaks by unsealing surfaces, increase the quality of protected goods such as groundwater and surface water and offer the best conditions for saving or waiving fees for rainwater in accordance with many municipal statutes. Legislators in many countries have made decentralized rainwater management a principle.
New laws now apply to decentralized rainwater treatment: To protect our waters, rainwater from traffic areas must be treated - pollutants must not be allowed to enter the groundwater!
Rainwater-treating surface coverings with general type approval from the German Institute for Building Technology can also be used where conventional ecological paving systems are not permitted.
The general type approval is reliable proof of the usability of non-regulated construction products or types of construction. The German Institute for Building Technology (DIBt) in Berlin is responsible for issuing them.
A type approval primarily indicates tested products and systems. In relation to the rainwater-treating surface coverings of the proWater product line, this also means safety in planning, tendering and professional installation, as the construction method and all components are precisely defined and described. It also contains information on operation and maintenance as well as the manufacturer's own and external monitoring. In addition, the DIBt seal ensures simplified approval procedures. All in all, the type approval offers clear advantages for all planners and local authorities (civil engineers, architects, landscape architects, water authorities, etc.) as well as for paving professionals and building owners.
In the capital, affordable residential buildings such as the one on Sterndamm in the south-east are being built, which not only offer affordable rents, but also create a green refuge between the buildings with small playgrounds and individual facilities for the residential community of dementia patients.
The "Squareville" hotel building is located in Munich's new Freiham district, which extends over 350 hectares and will be home to more than 25,000 residents.
Berlin is responding to climate change with "sophisticated rainwater management, cool retreats and lots of greenery", as implemented in the SpreeOne Living residential and commercial building in Charlottenburg in the north of the city.
The stone systems from the GDM.DRAIN stone proActive line with DIBt type approval enable efficient cleaning of the seepage water and reduce the required distance for the groundwater level to 1 m, which made it possible to transform the inner courtyard in Münchwilen into an attractive parking space with environmental benefits.
The Kunstvilla in Nuremberg's Marienvorstadt district, a regional art museum, was faced with the task of restoring a piece of its former quality through external references to the so-called garden level and appropriate materials.
Stölpchenweg in Berlin's Wannsee district is one of the capital's top residential addresses.
Today, eco-paving systems not only provide infiltration and evaporation, but also groundwater protection. In a new housing estate in the Eiche district of Potsdam, around 8,500 square metres of this system stabilize the traffic areas.
