Tree Protection Zones (TPZs)

Feb 18, 2025Tree Protection Zone, General, Residential Property

This week, the team successfully completed a driveway project that involved areas of Permcon, due to the Tree Protection Zones (TPZs) and the constraints of hard surfaces.


The team did an excellent job matching the stone in the exposed aggregate concrete with the permeable concrete, ensuring a seamless and aesthetically pleasing finish.

Project Considerations Before Specification

Before installing a Permeable Footpath, site conditions should be assessed to confirm suitability and expected performance outcomes. This helps ensure the system is matched correctly to environmental and structural requirements.

Key considerations include:

  • Soil type and infiltration capacity
  • Local rainfall intensity and storm patterns
  • Sub-base design and drainage planning
  • Expected pedestrian and service load conditions
  • Surrounding infrastructure constraints

Next Steps: Planning To Specification

A Permeable Footpath provides a practical approach to managing stormwater while supporting durable, functional urban surfaces. It is suited to councils, developers, architects, and contractors working on infrastructure, public realm upgrades, and new urban developments.
