Root Space

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.

RootSpace G2

GreenBlue is very proud to announce a relaunch of RootSpace with some excellent improvements

New 400mm high version to enable a wider range of tree pit depths – now 5 different height configurations
Faster, simpler and easier assembly process

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
