Rockflow provides an innovative water management system around the roots of trees, in plant beds and on green roofs. The basis of the Rockflow system are sustainable stone wool elements with an extremely high capacity for water absorption and buffering. Rockflow stone wool elements have an available volume of 95%. This means that practically the entire volume of the elements is available for the collection of water. The water management system buffers and supplies water to the greenery. In this way, Rockflow ensures that trees and plants always have available water, even during a growth period or drought.
