The GreenBlue Urban RootSpace® 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.
In 2001, GreenBlue Urban produced the world’s first purpose made commercial structural soil cell for urban tree planting. Since that time, thousands of trees have benefited and continue to benefit, from access to uncompacted soil volumes – beneath heavily engineered pavements and roadways.
RootSpace® is the next generation soil protection product, developed by GreenBlue Urban to reduce cost, cut down installation time, and incorporate industry leading soil aeration methodology – a vital and often overlooked component in tree pit design.

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 configurations (this is based on a typical macadam type road construction and the standard tree pit detail of GBU specification):
| RootSpace configuration | Height | Subbase DTp Type 1 depth | Macadam depth * | Total depth |
| 400 single | 475mm | 150mm | 150mm | 300mm |
| 600 single | 675mm | 300mm | 150mm | 450mm |
| 400 + 400 | 875mm | 300mm | 150mm | 450mm |
| 400 + 600 | 1075mm | 325mm | 150mm | 475mm |
| 600 + 600 | 1275mm | 325mm | 150mm | 475mm |
* Total depth of bound bituminous layers (Minimum construction depths for a full range of wheel loads are available separately)
