Key Challenges
To create a situation where parking places and tree pits must be combined.
The Purpose/Function of the System
To create a situation where parking places and tree pits must be combined.
- The Permavoid structure accommodates the vertical and lateral forces from vehicular loading; whilst the soil remains uncompacted.
- The Permavoid can act as a container to hold the rich soil.
- The Permavoid provides the ideal sub-base replacement layer for the pavement (doesn’t rut etc).
- The air gap within the Permavoid facilitates re-oxygenation of the soils.
- The air gap prevents root growth into the pavement
- The air gap and the un-compacted soils facilitate the movement of water, gasses and oxygen through the system.
