The GreenBlue Urban RootSpace® system is essentially a soil 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.
