- Stormwater Infiltration Boxes



Decentralised, Tailor-Made Solutions for Stormwater Infiltration And Retention: GEOdek infiltration boxes store excess stormwater and release it afterwards. Made from Polypropylene, they exhibit exceptional strength and are resistant to all chemicals normally found below ground. GEOdek can be used under sealed surfaces such as streets and parking lots. 7 standard types cover requirements for different types of loads.

Technical Stormwater Attenuation

Natural stormwater infiltration needs uncovered surfaces. The growing number of sealed surfaces increases the risk of flooding and/or poor waste water treatment. One means to prevent those risks are technical infiltration systems like GEOdek infiltration boxes. During the storm, they collect the water below the covered ground and release it later into the sewage drains.


GEOdek boxes are available in 7 standard strength types. Their combination in single or multi-layer systems offers a great flexibility to cover all requirements with regard to type of traffic load and earth coverage.

Our GEOdek design program helps our customers to easily choose the appropriate type, allowing economically and ecologically-friendly realization of their projects.

TÜV certified

In addition to in-house tests, the quality and strength of the GEOdek boxes is independently tested by external institutes like TÜV.


GEOdek can as well be used for

  • Rainwater Harvesting
    Rainwater harvesting systems with GEOdek resemble attenuation systems. Tanks can be built without concrete or steel surrounds. An impermeable membrane around the fill structure prevents infiltration.
  • Infiltration of Treated Effluents
    For the infiltration of treated effluent from medium and small waste water treatment plants GEOdek boxes can be used as well.

  • No need for stormwater drains
  • Decentralized, flexible and tailor-made solutions
  • Cost saving by lower wastewater discharge charges
  • Easy and quick installation
  • TÜV and BBA certified
