Tree Root Damage to Sidewalks and Driveways
in Springfield, OH
A lot of Springfield's older neighborhoods have silver maple and oak trees planted right next to sidewalks. Those trees are now 50 or 60 years old with root systems that have nowhere to go but under the concrete. Clark County requires homeowners to maintain the sidewalk in front of their property, so a lifted slab is your problem to fix.
Quick Answer
Tree roots grow toward water and air, and a concrete sidewalk or driveway traps both underneath it. Many Springfield homes have large silver maples planted close to the street in the 1960s and the roots have been cracking pavement ever since. A trimmer can cut specific roots and remove surface wood to level the area again. This will not stop roots forever but it buys several years.
Telltale Signs
Warning Signs to Watch For
- Concrete slabs lifted one inch or more above the slab next to them
- Cracks in the driveway or sidewalk running in a curved pattern following root direction
- Visible roots running along the surface of the lawn near pavement
- Asphalt rippling or bubbling in a line across the driveway
- Settled areas in the lawn that trace the line of a large root
Root Causes
What Causes Tree Root Damage to Sidewalks and Driveways?
Shallow Roots Under Compacted Soil
In Springfield, clay soil compacts under foot traffic and mowers, which pushes roots sideways near the surface instead of down. When roots hit the underside of a slab they keep growing and the slab goes up.
The Fix
Root Pruning and Pavement Reset
A trimmer cuts the offending root at a point that protects the tree's stability, then the concrete can be ground down or reset. If the same root is cut too far back it can destabilize the tree, so the cut location matters.
Trees Planted Too Close to Pavement
Many Springfield homes built in the 1950s and 1960s have trees planted within three feet of the sidewalk edge. That was standard practice then. There is simply not enough space for the root system that a 50-year-old tree needs.
The Fix
Root Barrier Installation or Tree Removal
A deep root barrier redirects roots downward away from the slab. If the tree is too close and too large, removal followed by a smaller species replanted farther back is the only lasting fix.
