A permeable pavement designed to allow rainwater to filter through 8 mm joints and drain into a specially prepared sub-base beneath the pavers. This sub-base acts as an attenuation tank, where water is stored or channeled to a receiving course in a controlled manner.

The Terana® six Acqua Joint pavement is part of the most comprehensive SUDS (Sustainable Urban Drainage Systems) techniques, reducing the possibility of flooding, removing impurities, and helping to prevent water pollution. Furthermore, it is suitable for large public surfaces that support vehicle loads.
