costly damage to pavements, roads, building

foundations and buried installations. RootBarrier

Owners hundreds of thousands of dollars annually

in expensive repair bills from intrusive roots.

ApplicationRootBarrier should be used anywhere where tree roots can have an adverse

affect on surrounding infrastructure such as paths, roads and paved areas.

Applications include streetscapes, pathways and plaza courts.

DescriptionMade of recycled high density polyethylene, RootBarrier is lightweight,

flexible, yet extremely durable and resistant to UV light, chemicals and

fungus. Available in 600mm, 900mm or 1200mm widths.

Benefits• Lightweight and easy to install in tight confines working

with narrow width excavators

encouraging deep rooting/anchoring and avoiding

root circling
