But in some cases, subsidence and structural damage can be linked to tree roots. Make the trench 1 foot deep or deep enough to contain the barrier. Calculating the Structural Root Zone (SRZ) is a bit more complicated. So, for example, if a tree is 6m wide, the radius of the canopy is 3m. The root systems of some oaks, for example, can extend well beyond the canopy dripline. Most tree roots spread 2-3 times the radius of the canopy, and often reach out 5 times the radius of the tree canopy or more in dry conditions. The Ficus genus of plants includes more than 800 woody species found mostly in tropical zones, with a few extending into warmer temperate regions.

The DRC (Diameter Above Root Crown) is the width (diameter) of the tree trunk measured immediately above the root crown or root buttress. The formula for the Structural Root Zone (SRZ) radius is as follows: To calculate, multiply the DRC value by 50, then multiply the result by the power of 0.42 (which is not the same as simply multiplying it by 0.42), and then multiply the result by 0.64.

Ficus macrophylla, commonly known as the Moreton Bay fig or Australian banyan, is a large evergreen banyan tree of the family Moraceae native to eastern Australia, from the Wide Bay–Burnett region in the north to the Illawarra in New South Wales, as well as Lord Howe Island.Its common name is derived from Moreton Bay in Queensland, Australia.It is best known for its imposing buttress roots.

Also, pachycauls – trees with thick, fat stems/trunks with few branches, such as Baobabs and Brachychitons technically do not conform to the definition of trees according to arborists, and therefore do not technically have a SRZ, though in the real world are trees and do have structural roots!

Blocked drains and lifted paving may also be a problem. Tree varieties will grow into small shrubs inside the house. There are three conventions for calculating the Tree Protection Zone (TPZ): Note: Section 3.2 of the Australian Standard AS4970–2009 (Protection of Trees on Development Sites) states that the TPZ of palms and other monocots, cycads and tree ferns (pachycauls) should not be less than1 m outside the crown projection (canopy drip line).
