The D-Raintank manages two important tasks; retention of water below the ground and soaking it away. The D-Raintank® combines an extremely high storage capacity with great stability for underground use. It is a double box element, put together from statically calculated grid plates, and is completely wrapped in a geo-textile. The individual tanks can be laid in various ways depending on the space situation. When they are combined they form underground rainwater storage compartments in which the rainwater is first taken up and then soaked away or taken elsewhere.
Surfaces to be drained are e.g.:
• Terraces and yard surfaces.
• Public squares
• Par parks / garage forecourts.
• Parking and foot paths.
• Sports complexes
• Other sealed surfaces'
