State of the art production machinery
DRAINMAX tunnel infiltration systems are manufactured on one of Europe's most modern and largest injection molding facilities. In addition to consistent quality, this also guarantees the lowest possible production costs and ultimately a competitive price per cubic metre for rainwater management and water storage applications.
Minimal transport costs
From our vast warehouse, DRAINMAX tunnels can also be delivered directly to construction sites worldwide, depending on the project. Up to 57.6 m³ of usable volume can be stacked on a pallet, or 518.4 m³ per 40' HC container. More is not possible! Since transport costs currently account for a huge portion of total costs, the cost advantage is significant. Other systems require considerably more transport volume. This makes DRAINMAX systems highly efficient, even for export.
Minimum space requirements
Compared to conventional gravel infiltration systems with a maximum retention volume of 35%, the DRAINMAX Tunnel offers 100% retention volume, and in the installed version, for example, with a 100 m³ system, this is approximately 62 %. In practice, this means that large quantities of water can be retained, stored, infiltrated, or drained away in a very small space using the DRAINMAX Tunnel infiltration system. This is important for many projects today, as space is at a premium in industrialized regions. The flat design of the DRAINMAX systems offers a particular advantage during installation. This saves excavation work and allows the use of smaller equipment. If there is still not enough space, the gravel layer can be raised. Alternatively, INTEWA tanks, honeycombs, or boxes can be used.
