Tree Canopies

Rapidly growing tree canopies without the risks

A safer, more sustainable way to upgrade streetscapes

From providing shade to purifying air and adding value to cities, trees deliver a huge range of benefits. However, when planted incorrectly, they can cause costly damage to infrastructure and put people’s safety at risk.

At Citygreen, we help clients, communities and stakeholders mitigate the risks associated with street trees. Our durable, proven and sustainable products promote rapidly growing tree canopies, while simultaneously preventing damage to streetscapes.

The truth about tree root damage

Having worked on projects around the world, we’ve seen the worst impacts of tree root damage. Broken footpaths can cause trip hazards that require costly, ongoing maintenance. Insurance claims lead to policy hikes, which can blow out city budgets. But that’s just the beginning.

If a city is seen to be unsafe, the reputational damage can be dire. It can bring down property values and deter people from visiting or investing. With Citygreen you can have safe, shady, tree-lined streets while also protecting your bottom line.

“The high soil volume [in Stratavault] allows trees to develop extensive root systems and, in turn, large canopies, which provide shade and visual relief in the city.”
–Fraser Miller, Rough and Milne Landscape Architects

Precision engineered treepits

Trees in cities require special care and proper planting from the outset. They need uncompacted soil volume, just like in nature. That’s exactly what Citygreen delivers with our Stratacell and Stratavault soil cell systems.

As the world’s strongest structural soil cells, Citygreen systems supply 94% of total soil volume for healthy root growth. Made from 100% recycled polymers, they contain no steel parts. That means no rusting, no corrosion –and, best of all,no maintenance.

As well as helping trees grow healthier, larger and faster,Citygreen’s engineered treepits will withstand the toughest conditions with incredible strength and durability. Heavy paving,harsh climates, high traffic. Guaranteed.

“The results have reflected exactly what the [Stratavault] system claims to do –providing enough strength to support the concrete slabs above while allowing space below for the trees to generate root growth and become established within the environment.”
–Corey Milton, Lake Macquarie City Council

Revolutionary root management systems

When it comes to keeping tree roots in check, we leave nothing to chance.Over years of research, design and development, Citygreen has created a range of industry-leading root management products that make trip hazards and streetscape damage a thing of the past.

Our innovative RootDirector product diverts tree roots downwards, so they can safely establish without surface damage. By ensuring tree roots stay well below pavements, RootDirector prevents damage from root heave –a condition that often results in removal of trees, to the detriment of the community and environment.

Our ReRoot linear ribbed barrier guides roots in a similar way but is not restricted by size or shape. It’s the perfect solution for projects that require a root-free corridor for service utilities, or trees in a high traffic area.

“Citygreen’s Root Director system has allowed the new trees to prosper without damaging the footpath. Root Director is a quality root modification product which modifies the root morphology, directing the roots 400ml below the surface to avoid damage to the pavement above.”
– Kieran Bowd, Lake Macquarie City Council

Many clients come to us when infrastructure is irreparable, or trees have already been destroyed. But why wait until the damage is done? By investing in Citygreen’s quality solutions, you can save time, money and stress down the track.
