The GDM.KLIMASTEIN

Climate protection through innovation
Climate protection is more important for our future than anything else - and we are preparing the ground for it. The GDM.KLIMASTEIN gives paved surfaces climate-friendly properties that previously seemed unthinkable.

New perspectives for green-blue urban design

With the GDM.KLIMASTEIN, GODELMANN has created a world first that can make a significant contribution to improving the urban climate: The first paving block with a three-layer structure protects the groundwater through proven pollutant retention and achieves an evaporation rate comparable to that of a meadow.

Built-up and paved areas must make their contribution to a positive urban climate. The GDM.KLIMASTEIN provides new answers to the most pressing questions and is an elementary building block for the concept of the sponge city. It can be used to recover the soil as a natural resource.

Storing, filtering, cooling

We live in the age of cities. Drought and heat stress affect the urban climate. Heavy rainfall events are on the increase. Time for a solution to rethink paving. Time for paving stones that achieve a significantly higher evaporation rate, are almost as high as a meadow and can do even more for the city of the future.

A PAVING STONE HAS THREE TASKS IN THE CLIMATE-RESILIENT CITY OF THE FUTURE

  1. Protect the environment from noise, heating and pollutants.
  2. Infiltrate and store moisture on site to cool the environment through evaporation.
  3. Stop pollutants from entering the groundwater.
  1. Catalyst layer: The visible surface reflects heat radiation, reduces noise emissions and neutralizes air pollutants. Moisture passes through the joints into the storage layer and into the ground.
  2. Storagelayer: The core area can absorb and release large amounts of moisture. In this way, paved surfaces achieve a similarly high evaporation rate as a meadow.
  3. Capillary layer: The sub-layer is less permeable, more moisture is stored and also absorbed by the soil. This leads to increased evaporation.

Thanks to its intelligent proActive properties, the GDM.climate stone is able to do more for the urban climate than any surface system before it.

proDrain
Decentralized surface infiltration keeps the natural water balance on site largely intact and relieves the burden on the sewer network.

proVapo
Evaporation activity improves the urban climate: higher humidity and more cooling.

proWater
The joint material filters pollutants out of rainwater from traffic areas: Groundwater protection.

proAir
Thanks to a modified concrete formulation, the surface contributes to the reduction of air pollutants

proReflect
The surface reflects the heat of solar radiation and protects against overheating.

proSilence
Certain formats, the joint width and surface structure, as well as the laying pattern guarantee a particularly quiet paving surface.

proCycle
Conserves raw material resources through recycling and upcycling.

The sponge city principle

The Sponge City urban planning concept aims to absorb and store as much rainwater as possible instead of draining it away. The aim is to protect the city from flooding, heatwaves and drought and to improve the urban climate.

With the GDM.KLIMASTEIN, areas can be paved for traffic without sealing the ground. With this completely new surface covering system, GODELMANN offers a pioneering solution for making built and paved surfaces climate-resilient
