What Houzz contributors are saying:
Know exactly where the roots are. As with any construction near existing trees, it is important to protect the root zone from damage. A general rule of thumb considers the critical root zone as determined by the tree’s trunk diameter or by the drip line measured from the trunk to where the branches extend. However, this calculation is not precise enough when building close to an existing tree. Instead, air-spade technology can blow soil away to reveal where the major roots occur. Using that information, a precise mapping of the roots can inform the exact locations of deck and foundation pilings as well as other structures.
