Where can you install drening?
Drening can be installed below any type of surface from the green area to an heavy traffic zone as long as it is put in place with the required placement stratigraphy.
Installation below builidings is not recommended.
Why use Drening if I can discharge the water in the sewage?
The authority of many zones requires a maximum water capacity that can be inserted through the net but usually limits are very restrictive. A DRENING properly sized basin, permits water disposal conforming to the regulations, avoiding net obstructions and preventing possible surface overflowings. Moreover, it is possible to put back the water in the subsoil to restore the hydrological balance and to contribute to the mantainance of aquifers.
