State of the art production machinery
DRAINMAX tunnel infiltration trenches are manufactured on one of the most modern and largest thermoforming production lines in Europe. In addition to consistent quality, this also guarantees the lowest possible production costs and ultimately a favorable m³ price for the entire infiltration or retention system.
Minimal transport costs
From the huge stockpile, DRAINMAX tunnel trenches can also be delivered directly to the construction site throughout Europe on a project-specific basis. Up to 40 m³ of retention volume can be stacked on one pallet or 360 m³ per truck or container. More is not possible! As transport costs today make up an enormous part of the total costs, the cost advantage is considerable. Depending on the design, conventional box-type trenches require up to 6 times the transport volume, since essentially only air is transported.
Minimum space requirements
Compared to conventional gravel trenches with a retention volume of approx. 35%, the DRAINMAX tunnel trench provides 100% retention volume. In practice, this means that large quantities of water can be retained, infiltrated or discharged in a very small space with the DRAINMAX tunnel trench. This is important in many projects today, as space is scarce in industrialized regions.
