GDM.CASCADE^® stone

• 6,9 % versickerungsfähiger Flächenanteil, Abflussbeiwert ψ = 0,25

Surfaces with an optimized SR value reflect the sun's rays and protect against the urban heat island effect. The less heated surfaces significantly increase the quality of stay.

• Overheating protection

The format, bevel design, joint width and surface structure, as well as the laying pattern, result in particularly quiet traffic areas. The noise reduction helps to improve the quality of life in urban environments.

• Noise protection

With the three-layer GDM.KLIMASTEIN, the moisture in the storage layer with its many pores is activated by solar radiation. The capillary layer is less permeable. As a result, more moisture is retained in the storage layer. Additional moisture is also transported from the bedding into the storage layer. This increases the efficiency by more than 10% compared to proVapo 45. The evaporation capacity is ≥ 50% of the annual precipitation.

• Evaporation ≥ 50 % of annual precipitation
