Why is very important to replace your walkway or sidewalk? On the city side is sometime when I have a trees along the walkway or sidewalks. Sometime the trees route is just a lift, like the flag, the concrete, and that this is very danger. It's like a hazmat trip.
And this is very important. You can do two ways. Some case you can just a grind down like the air if it's not too bad. But another way you had to replace, because the root is keep it grow and it's gonna keep lift more and more, more, when we just grind down. It's not last long.
It depend how fast the root is gonna grow, but it's very important. That's it is a safe, stay safe, anybody can trip over there. This is can be liability and it's very important to fix.
