<div dir="ltr">Is that broken sidewalk also on the Municipalities side of the property line? In edmonton, that may determine who pays for sidewalk repair. <div><br></div><div>In this situation I would remove the broken sidewalk, air excavate out the soil in the area of the sidewalk, place the gravel base for the sidewalk around and over the roots and repour the sidewalk to match the height of the first step. 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><br></div><div>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. In addition, the cement is scored every 12-16 inches before it cures (just as you would with sidewalk panels). the rebar will prevent the concrete from disjointing, and the scores in the concrete will control and perhaps hide the cracking</div><div><br></div><div>You will likely have to curve the walk around the tree. </div><div><br></div><div>raising the walk may allow you to avoid root pruning but you will have to do some minor filling and sod replacement to get everything to blend together.</div><div><br></div><div>I hope this helps. </div><div><br></div><div><br></div><div><br></div><div><div><img src="cid:ii_k2g893sx1" alt="image.png" width="485" height="562"><br></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><span><p dir="ltr" style="line-height:1.2;margin-top:0pt;margin-bottom:0pt"><br></p><p dir="ltr" style="line-height:1.2;margin-top:0pt;margin-bottom:0pt"><br></p><br><p dir="ltr" style="line-height:1.2;margin-top:0pt;margin-bottom:0pt"><br></p><br></span><div style="margin-bottom:0pt;background-image:initial;background-repeat:initial"><b>Trevor Thistle<font size="2"> </font><font size="1">Bsc.
