Concrete Grinding vs. Polyjacking for Trip Hazard Repair: What’s Best for Your Property?
Uneven concrete can be more than just an eyesore; it’s a serious trip hazard and brings down the value of your home. Whether it’s a sunken sidewalk, uneven driveway, or lopsided patio, these issues not only affect your curb appeal but also pose liability risks and can lead to injuries.
When it comes to fixing these hazards, two common repair methods stand out: concrete grinding and polyjacking (also called polylifting or polyurethane foam injection). But which is the better option? And how can BAM Basements and Masons of Des Moines help?
Let’s break it down.
Concrete Grinding: Quick Fix, Limited Longevity
What it is:
Concrete grinding involves mechanically shaving down high points on a slab to level it out with surrounding concrete. It’s often used for small height differences (typically less than 1 inch).
Pros:
- Fast and affordable
- Minimal disruption
- Works well for minor surface-level trip hazards
Cons:
- Doesn’t address the underlying cause (settling or erosion)
- Only reduces height difference — doesn’t restore original position
- Leaves visible grinding marks
- Can lead to dust and surface wear
Best for:
Temporary or cosmetic fixes on minor trip hazards.
Polyjacking (Polylifting): Long-Term, Structural Solution
What it is:
Polyjacking lifts sunken concrete slabs back into place using high-density polyurethane foam. The foam is injected through small holes beneath the slab, expands, and gently lifts it restoring it to a level position.
Pros:
- Raises and realigns sunken slabs
- Fills voids beneath concrete to prevent future settling
- Quick cure time (can walk/drive on within hours)
- Long-lasting, waterproof, and eco-friendly
- Less invasive and more cost-effective than full replacement
Cons:
- Slightly higher upfront cost than grinding
- Requires trained professionals and specialized equipment
Best for:
Sidewalks, driveways, patios, pool areas and concrete slabs with noticeable settling, voids underneath, or more than 1 inch of misalignment.
So, Which Should You Choose?
If you’re looking for a quick, cosmetic fix and the difference is very small, concrete grinding might be enough. But for most homeowners and property managers who want a permanent, structural solution that prevents future problems, polyjacking concrete lifting is the smarter investment.
