In this guide, we’ll break down the best ways to tackle uneven sidewalks in Portland, from what’s causing the problem to how to fix it—and when it’s time to call in the pros. Whether you’re a DIY fan or ready to hire help, we’ve got your back.
Why Do Concrete Sidewalks Become Uneven?
Knowing why your sidewalk’s gone wonky can help you stop it from happening again. Here’s what’s usually to blame:
Tree Roots
Nearby trees can send roots sprawling, shoving slabs upward.
Soil Erosion
Portland’s rainy days wash soil out from under slabs, letting them sink.
Freeze-Thaw Cycles
Water sneaks into cracks, freezes, expands, and throws things off-kilter.
Heavy Loads
Too much weight—like a loaded truck—can make slabs crack or dip.
Poor Installation
A shaky base or sloppy concrete mix sets you up for trouble later.
Once you’ve got a hunch about the cause, picking the right fix gets a lot easier.
Best Methods to Repair Uneven Concrete Sidewalks
How you fix your sidewalk depends on how bad it’s gotten. Here are the top ways to smooth things out:
Concrete Grinding
Best for: Minor bumps (under 2 inches)
How it works: A grinder shaves down high spots to even things out. It’s a fast, wallet-friendly way to boost safety without ripping up slabs.
Pros
- Won’t break the bank
- Done in a flash
- Keeps your slabs in place
Cons
- Only good for small differences
- Might not feel as slick as fresh concrete
Concrete Leveling (Mudjacking or Foam Injection)
Best for: Sunken slabs or dips from settling soil
How it works: Pros pump a mix of cement, sand, and water (mudjacking) or foam under the slab to lift it back up.
Pros
- Cheaper than starting over
- Takes just a few hours
- Holds up for years
Cons
- Won’t fix cracks on top
- Not great if the soil keeps shifting
Slab Replacement
Best for: Badly cracked or busted-up sidewalks
How it works: Out goes the old slab, in comes fresh concrete for a brand-new, steady surface.
Pros
- Fixes it for good
- Looks sharp
- Meets city safety rules
Cons
- Costs more than grinding or leveling
- Takes extra time and effort
Patching Small Cracks
Best for: Little surface cracks or scuffs
How it works: Fill cracks with concrete filler or patching goo to stop them from growing and keep water out.
Pros
- Keeps tiny cracks from turning big
- Cheap and easy for DIYers
Cons
- Doesn’t level uneven spots
- Might need touch-ups down the line

Pick trees with tame roots or add barriers if they’re near the sidewalk.
Improve Drainage
Make sure water flows away, not under your slabs.
Regular Inspections

Portland Sidewalk Repair Regulations
Here in Portland, it’s on property owners to keep sidewalks by their place in shape. The City of Portland Bureau of Transportation (PBOT) might send a repair notice if yours is a hazard. Ignore it, and you could face fines or a forced fix on your dime.
To stay on the right side of the rules:
- Check PBOT’s sidewalk repair guidelines online.
- Grab permits before big fixes.
- Hire a licensed pro who knows Portland’s regs.
