The HydroSpacer® HS 170 allows Zinco to come closer to its goal of bringing the water balance of a developed area closer to that of an undeveloped area. The basic idea is to have as much storage space as possible beneath the substrate and plant level. On the one hand this is to efficiently absorb heavy rainfall events and on the other hand to store water so that it is available to the plants. The accumulated water will supply the plants during dry periods, and in doing so will maintain their evaporation capacity over a long period of time.
The HydroSpacer® HS 170 can store up to 160 l/m² of water. Up to 11 l/m² of this can be provided to the plants each day.
The water accumulated in the lower area of the HydroSpacer® HS 170 remains on the roof and is therefore available to the plants for a longer period of time. When it rains, the upper area will fill temporarily. This water then drains off through the retention run-off limiter at a slower rate.
