Staircase Leading Past Existing Tree

In this example a staircase was designed to pass by an existing tree. Conventional methods of constructing a sub-base would have resulted in soil compaction and water deprivation for the tree, which would have had a long term impact on it's overall health. The roots were also too close to the surface of the soil for a cellular system, as this would have pushed the pathway too high.

Our RootBridge light duty was installed, replacing the angular stone base, and reducing the surface preparation depth from 300mm down to only 75 mm.
