How Tree Roots Cause Concrete to Shift
Tree-lined streets and shaded walkways are beautiful, but they can also come with hidden risks. In many Denver neighborhoods, nearby trees are a surprising culprit behind uneven concrete. As roots spread in search of moisture, they often grow directly beneath sidewalks, driveways, patios, and other slabs—displacing the concrete above.
Roots don’t need to be massive to cause damage. Even small root systems can lift slabs, creating raised edges and cracks. Over time, this root intrusion creates trip hazards and drainage issues that worsen with seasonal weather changes.
Signs Tree Roots Are Affecting Your Concrete
Wondering if nearby trees are causing your concrete problems? Here are a few common signs:
Slabs are lifting or buckling near tree trunks
Cracks appear in a pattern radiating from one side
Visible roots are pushing through seams or edges
Tree growth is concentrated near concrete surfaces
Uneven gaps or tilting slabs near sidewalks or driveways
If you’re seeing any of these signs, there’s a strong chance tree roots are playing a role.
Why Tree-Related Damage is Common in Denver
Denver’s urban canopy is made up of diverse tree species, many of which have shallow, aggressive root systems. When trees are planted close to sidewalks or driveways, they compete for space with concrete surfaces. The city’s clay-rich soil can also amplify the issue—holding moisture and encouraging roots to expand horizontally under slabs.
Combined with the region’s dry spells and freeze-thaw cycles, this creates the perfect environment for concrete disruption.
What Can Be Done About Root-Related Concrete Damage
Luckily, not all root-related concrete issues require tree removal. Concrete lifting (also known as mudjacking) is an effective way to restore slabs affected by root intrusion—without tearing them out or harming the tree.
Benefits of concrete lifting for root-related damage include:
- Restoring level, safe walkways
- Improving curb appeal and drainage
- Cost-effective alternative to full replacement
- Minimal impact on nearby landscaping
If necessary, roots can be trimmed or redirected in coordination with an arborist to prevent future problems.
