Causes Of Broken & Cracked Sidewalks
If you manage sidewalk maintenance you know that cracked sidewalks are common. Many times the cracks simply make the sidewalk look older, but under certain conditions they also become a safety risk and a liability to lawsuits.
Broken sidewalks are caused by a number of factors, some of which you can effect and other which you cannot. The most common cause of cracked sidewalks is movement under the ground. Tree root sidewalk damage is the most common. The slow growth of these roots lifts sections of concrete, causing them to be lifted and then crack. As trees are highly desirable, the best solutions are to plant trees farther away from sidewalks, or pick trees with deeper rather than shallow surface roots. Often this is not an option, so inexpensive repair methods such as horizontal concrete slicing can be employed and if needed be employed several times as needed for less than the cost of removing and replacing the broken sidewalk. |
