A closer look at this build-up at Silkeborg:

Water is our most precious resource and should be treated as such. 

Solution

Sandwich system

In a situation where trees are expected to grow in an urban and paved environment, compaction of the soil, superficial tree roots damaging the pavement and greatly reduced soil-gas exchange are known growth-limiting factors. The Permavoid Sandwich Construction eliminates these by creating a shallow, stable and open subbase for the hardscape to ensure optimum load distribution and high load bearing capacity, preventing compaction of the rootable soil volume underneath. The system is used in parking lots, residential areas, malls and bicycle paths, with a free choice of pavement systems like block pavers, concrete or asphalt.
