Air excavation will also give you a good idea of what the tree has for structural roots. for example, it the tree has 6 roots under the walk but only one needs to be removed to replace the concrete, you would feel more confident that a selective root prune won't render the tree hazardous. however, if the root you need to cut is 1 of only 2 roots on that side of the tree, thats something to be concerned about. </div><div class=""><br class=""></div><div class="">In Edmonton we do something we call a tree treatment when replacing sidewalks that have failed due to root conflicts. this sometimes involves decreasing the thickness of the base under the concrete and / or reducing the thickness of the concrete, but reinforcing it with additional rebar.
