Urbastyle Lithos | Climate Stone

The Climate Stone is a climate-adaptive concrete paving stone that combines infiltration, water storage and evaporation. Rainwater is absorbed through the joints, stored temporarily in the system and then brought back to the surface, where it can evaporate. In this way the stone helps to absorb peak rainfall while cooling the surroundings. The system can store up to 10 litres of water per m², evaporate up to 70% of that water again in summer, and keep the surface up to 12°C cooler than conventional paving. The relatively narrow joints preserve a comfortable walking surface. The Climate Stone has won several international awards, including the Deutscher Nachhaltigkeitspreis, the Bundespreis Ecodesign and the Green Award.
