Water-permeable pavements are mainly surface pavements in road and path construction, where rainwater can seep away directly to a large extent. The aim of this construction method is to reduce surface sealing. The reduced or delayed discharge of rainwater leads to a reduced load on the sewer system and the sewage treatment plants. The area of application of these coverings is versatile, but soil mechanical, hydrological and other conditions must be observed. The leachate must be uncontaminated and must not pose a risk to soil, vegetation and groundwater.
