Constructing root space for trees

Use of tree trenches beneath pavements as an approach to urban greening in Brisbane, Australia. [UMN]

"Over the last 6 years Brisbanes central business district has grown significantly greener and more pedestrian friendly, using a combination of "tree trench" technology and footpath widening. Millions of spectators at the Olympic Games in Sydney last year, walked along boulevards lined with fig trees and jacarandas growing in tree trenches covered with porous paving. Incorporating tree trenches beneath pavements in both site upgrades and new projects, is an exciting and cost effective approach to greening urban centres." [Abstract]
