What Tree Root Concrete Damage Tells You About Your Concrete Repair
Tree root damage shows as concrete lifted or heaved where a root has grown beneath it, cracks radiating from the raised area, and sections that later drop as roots die back or disturb the soil. Roots seeking water grow under and alongside driveways, sidewalks, and patios, and their expansion pushes the slabs up, cracking them and creating trip hazards. In Alabama's tree-heavy neighborhoods and moisture-rich clay, root-driven concrete damage is common. Repair combines addressing the root path, then lifting or grinding the affected slabs back to a safe, level surface.
Alabama's mature tree canopy and moist clay drive frequent root heaving of driveways and sidewalks, so root-damaged concrete repair is common work for APS across its markets.
What Causes Tree Root Concrete Damage in Alabama Homes
Root Growth Under the Slab
Tree roots grow toward moisture beneath and beside concrete, and as they thicken they exert strong upward and lateral pressure that heaves and cracks the slabs.
Cracking From Uplift
As a root lifts one part of a slab, the concrete cracks under the bending stress, often radiating from the raised point.
Settlement After Root Dieback
When roots die back or are removed and the disturbed soil consolidates, the previously heaved section can then drop, creating new unevenness.
Moisture Competition in Clay
Roots drawing moisture from Alabama's clay soil intensify the shrink-swell movement around the slab, compounding the displacement.
Signs You Should Not Ignore
- Concrete lifted or humped over a root
- Cracks radiating from a raised area
- A trip lip where a slab has heaved
- Nearby tree roots surfacing at the edges
- Sections dropping after roots were cut or died
How We Diagnose and Repair the Problem
- 1
Free On-Site Assessment
An APS technician visits your property, documents the symptom and severity, and reviews all related indicators to build a complete picture.

Root Cause Diagnosis
After addressing the root path, APS grinds down minor heaves and lifts or relevels displaced slabs with foam, restoring a safe surface. Badly shattered sections may need targeted replacement.

Repair With Transferable Warranty
All APS foundation repairs carry a warranty that transfers to future owners. Serving Birmingham, Mobile, Huntsville, and Columbus, GA.
“A root under a slab is a slow hydraulic jack. We deal with the root path, then grind or lift the concrete back to a surface you will not trip on.”
Frequently Asked Questions
Can concrete lifted by tree roots be fixed without removing the tree?
Often the concrete can be ground or relifted and the root path managed without removing a healthy tree, depending on the situation. APS assesses the root cause and recommends an approach that protects both the slab and, where possible, the tree.
Why did my slab crack over a root?
A growing root exerts strong upward pressure. The slab cannot flex enough to accommodate it, so it cracks and heaves at that point, creating the trip lip and radiating cracks.
Will grinding the high spot fix it?
Grinding removes a minor trip lip, but if the root keeps growing or the slab is badly cracked, more is needed. APS combines grinding, lifting, and root-path management for a lasting result.
Is this the same as tree roots damaging my foundation?
This page is about roots damaging flatwork like driveways and sidewalks. Roots can also affect foundations by drying and shrinking the supporting soil, which APS addresses separately under foundation repair.
