City trees

In a situation where trees are expected to grow in a paved environment, compaction of the soil, superficial tree roots damaging the pavement and a greatly reduced gas exchange with the soil are known for growth-limiting factors. The Permavoid Sandwich construction eliminates these limitations by creating a stable and open raft beneath the pavement to ensure healthy roots.

Permavoid future-proof growing sites are designed in such a way that the tree no longer causes costly and potentially dangerous damages to the pavement. The nuisance of frequent and reoccurring pavement repairs become a thing of the past. With Permavoid roots are prevented to grow where they cause damage, seperated from the pavement with a layer of air, while providing them enough space to develop and flourish, away from the paved surface.

Just like in nature, we collect, store and naturally return water to the trees. Whether they grow in open soil or paved circumstances, trees become an integral part of urban rainwater management. By balancing stormwater availability and potential tree evaporation with irrigation based on natural capillary rise from below, we prevent flooding of the growingsite each time it rains.

Healthy city trees reduce the urban heat-island effect, but the amount of water needed to be able to actually do so is often underestimated. Without sufficient water the tree cannot grow to its full potential to provide us with his much needed services to improve city life.
