With permitted partial infiltration, the DRAINMAX system with tunnel elements is an extremely interesting alternative. The low height offset between inlet and outlet in combination with large space flexibility and a very high storage volume are the advantages of this variant. If no water is allowed to enter the surrounding soil from the system, it can be sealed with an EPDM foil on site.
