Installing/Upgrading Surfacing in RPAs (SGN 9)
Establishes:
- Guidelines for installing new surfacing or upgrading existing surfacing in RPAs while minimising root damage.
- Recommends the use of three-dimensional cellular confinement systems filled with washed stone to distribute loads and avoid soil compaction.
- Advises against conventional surfacing installation methods that require excavation and compacting a supporting sub-base.
- Provides options for edge retention that do not involve significant soil disturbance.
Weak Points:
- Ensuring proper installation techniques and avoiding conventional methods that could damage roots is essential.
- The effectiveness of proposed solutions depends on careful planning and execution to prevent compaction and maintain permeability.
