Set of seepage tunnels - packages

Drainage packages consist of drainage tunnels, closing plates, geotextile fabric and vents. Drainage tunnel sets are designed for well-permeable soils (with a filtration coefficient kf ≥ 0.00005 m/s). The purpose of the tunnel is to infiltrate rainwater into the ground collected from roofs, parking lots and roads. The drainage tunnels are modular, so they can be connected together with snaps. In this way, you can create a drainage line that is adapted to the area to be drained. The tunnels can be placed in parallel in a single layer. It is also possible to connect them with their bottoms, which provides twice the accumulation capacity, with the same surface area. Vehicle traffic of up to 40 tons can pass over the sequence of drainage tunnels.

Assembly and laying of the tunnels is intuitive and very simple. Thanks to the modular design of the tunnel, transportation is also greatly facilitated - the tunnels can be stacked (up to 30 tunnels fit on 1 pallet). When installing the water seepage system into the ground, appropriate distances should be maintained:

  • The seepage system should be a minimum of 6 m from adjacent buildings (without insulated basements).
  • Also important is the groundwater level, which should be at a minimum depth of 1 m from the bottom surface of the tunnels.
  • The seepage system should be located from trees at a distance equal to the diameter of the tree crown.
Details of installation can be found in the manufacturer's instructions. We encourage you to familiarize yourself with the materials. Additional equipment on individual request: filter settling tank - the number depends on the number of drainage pipes of the system.
