RootSpace AirForm

Short description

The GreenBlue Urban RootSpace® AirForm system is essentially a pavement support system – designed for maximum soil and rooting volume, to be ‘utility friendly’, with economic freight and industry-leading strength characteristics.

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

The following table gives the minimum allowable paving construction depths required to disperse a 4.5 tonne wheel load (as an example) on different RootSpace AirForm configurations (this is based on a typical macadam type road construction and the standard tree pit detail of GBU specification):

RootSpace AirForm configuration Height Subbase DTp Type 1 depth Macadam depth * Total depth
400 single 19″ (475mm) 6″ (150mm) 6″ (150mm) 12″ (300mm)
