How We Fix Sidewalk Trip Hazards Without Full Replacement

Trip hazards on sidewalks are more than just a nuisance — in New York City, they can lead to DOT violations, liability issues, and even lawsuits. But not every uneven slab or crack means you need a full sidewalk replacement. At Eden Contracting, we specialize in cost-effective solutions that address sidewalk trip hazards without tearing out the entire walkway.

Here’s how we do it.

What Is Considered a Trip Hazard?

In NYC, a sidewalk is considered a trip hazard if there’s a height difference of ½ inch or more between adjacent concrete flags. These often form due to:

• Tree root growth

• Ground settling

• Freeze-thaw cycles

• Heavy foot or vehicle traffic

Techniques We Use to Fix Trip Hazards Without Full Replacement

1. Concrete Grinding

One of the most effective and affordable methods.

• We use a precision grinder to shave down the raised edge of the concrete.

• This creates a gentle slope that removes the abrupt trip risk.

• It’s ideal for minor elevation differences up to 1 inch.

• Fast and clean — no need for major demolition.

💡 Bonus: Grinding helps maintain original sidewalk layout and is DOT-compliant when done correctly.

2. Concrete Leveling (Slabjacking/Mudjacking)

Used when a sunken sidewalk slab needs lifting.

• We inject a grout or foam mixture beneath the sunken slab.

• The material expands and lifts the concrete to its proper height.

• No concrete replacement, no heavy equipment — just strategic lifting.

This method works best when the slab is intact but uneven due to soil erosion or compaction.

3. Edge Beveling and Slope Repair

In cases of minor misalignment:

• We create a slope or bevel along the raised edge using specialized tools or patching compounds.

• This helps reduce abrupt edges and makes the surface safer for walking.

• It's a temporary solution but still very effective for compliance and safety.

4. Joint Repair and Crack Filling

Trip hazards can also form at open joints or cracks.

• We clean and fill the cracks using a flexible, weatherproof concrete filler.

• For open joints, we use sealants or patch materials to stabilize and prevent further movement.

While this doesn’t lift slabs, it prevents water infiltration that can worsen damage.

When Full Replacement Is Necessary

While we aim to save our clients time and money, there are situations where replacing the sidewalk flag is the only safe and legal option:

• Slabs with multiple cracks or severe damage

• Sections raised by large tree roots

• Concrete that’s crumbling or spalling beyond repair

In these cases, we provide full-service removal and repour — always up to NYC DOT standards.

Why Choose Trip Hazard Repair Instead of Full Replacement?

• ✅ Saves thousands in repair costs

• ✅ No long permit wait times (for minor work)

• ✅ Faster project timelines

• ✅ Minimal disruption to pedestrian flow or your property

• ✅ Keeps you compliant and reduces liability risk
