RootSpace AirForm

Description

The GreenBlue Urban RootSpace AirForm Pavement Support System is an engineered load-bearing soil cell with optimal soil volume for maximum rooting volume as well as the ability to accommodate services. RootSpace AirForm is manufactured from 100% recycled material, designed for economic freight and is the culmination of more than 27 years experience in helping establish trees in complex urban environments.

100% recycled polypropylene
Only 2 main interlocking components
Very open format for optimal soil volume
Highly engineered lattice structure optimizing world lead strength v. cost ratio
Unique lid creates essential air zone above soil
Unique interlocking structural side panel

Optimum conditions for soil biology maximising root growth & tree health
Very fast, simple and easy to assemble reducing installation time & costs
Designed for easy integration, and re-excavation for maintenance, of utilities
Minimum excavation depths required
Can be used close to highways due to world leading lateral performance

Material

100% recycled polypropylene
