Key Challenges


  • High traffic intensity
  • High ground water level
  • Poor growth development of current trees; no prestigious street appearance
  • Bad soil conditions
  • Diagonal tree pits at surface



  • Use of the strong and tested concrete Treebox HP construction, which can handle high traffic loads.
  • A lower model of the concrete crosses is developed and used to stay above the high ground water level.
  • A layer of drainage sand is applied to function as an extra barrier between the ground water and the nutrient tree soil.
  • High nutrient soil is processed in the construction, that provides an healthy growth environment for the trees.
  • Through the concrete slabs on top of the construction, this soil will stay non-compacted.
  • Permavoid® units are used as a permeable wall construction. This will create an “open” barrier that lets water an oxygen into the construction for an optimal natural environment.
  • The cutout for the tree pits are diagonal divided over two concrete slabs to create the desired surface design.
