Best price per m³

Optimized production, minimum transport volume, minimum space requirement, huge storage volume and fast laying performance result in the DRAINMAX tunnel trench at the best price per m³ storage volume that can be achieved with plastic trenches.

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.

Fast installation performance

Due to the low weight of 30 kg, one tunnel can be carried by 2 people. The tunnels are connected to each other by overlapping. With only three different component shapes, 360 m³ can be laid in 8 hours.
