Sunken sidewalks can redirect water toward a home and create tripping hazards. This updated case study shows how Acme Concrete restored proper pitch to a Woodstock, IL front walk using modern polyurethane lifting—without mudjacking.
Key Project Takeaways (Q&A)
Q: What is the best way to fix a sagging concrete sidewalk in Woodstock, IL without replacing it?
A: Acme Concrete levels sidewalks with polyurethane injection, lifting sunken panels and restoring proper pitch with minimal disruption.
Q: Why should homeowners in Woodstock, IL fix a sinking sidewalk sooner rather than later?
A: A settled sidewalk can pitch rainwater toward the foundation, erode the sub‑base, and worsen settlement; early leveling reduces risk and future repair costs.
Q: How does polyurethane sidewalk raising compare to mudjacking in Woodstock, IL?
A: Lightweight, water‑resistant polyurethane reduces washout risk and uses smaller injection holes compared to heavy slurry mudjacking.
Case Study: Correcting a Sagging Front Walk in Woodstock, IL
The front walk at a Woodstock home was gradually settling, creating a low spot that began pitching water toward the house. While it wasn’t yet a major trip hazard, the drainage path was a red flag: water was finding its way under the slabs, loosening the sub‑base, and setting up more settling over time.
What We Found
Several sidewalk panels had dropped, causing a shallow basin near the entry.
During rainfall, water collected and flowed toward the home instead of away from it.
Continued erosion under the slabs would have accelerated future settlement and cosmetic cracking.
The Fix: Polyurethane Injection
Acme Concrete raised the affected slabs by injecting expanding polyurethane beneath the sidewalk. The material filled voids, gently lifted the panels to match adjacent sections, and re‑established a positive pitch away from the house. Compared to tear‑out and replacement, this approach is faster and far less disruptive to landscaping and daily use.

Why Fixing Early Matters
Addressing settlement before it becomes a trip hazard protects people and the property. Once water starts moving under slabs, it can wash out support soils, open voids, and put added stress on panels and joints. Correcting the pitch early is a simple way to safeguard the walkway and help prevent bigger, more expensive issues.
The Result
We lifted the walkway back to its intended elevation and alignment. Now that the slope is correct, rainwater sheds away from the home rather than toward it. The finished surface looks clean and even, and the repair avoided the mess, noise, and downtime of full replacement.
Frequently Asked Questions
How does polyurethane lifting help with drainage around sidewalks in northern Illinois?
Polyurethane injection restores the sidewalk’s intended slope, which redirects surface water away from the home. The expanding material also fills voids that allow water to pool under slabs. By stabilizing the sub‑base and improving pitch, the walkway becomes less vulnerable to continued washout.
What typically causes sidewalks to sink in Woodstock and nearby communities?
Common causes include seasonal freeze‑thaw cycles, downspout discharge near slabs, poor compaction of the original base, and water leaking along joints. Over time, these factors remove or weaken support soils. When voids form, concrete settles until the slab finds new support—often creating an uneven or tilted surface.
Is polyurethane durable through Chicago‑area winters?
This polyurethane performs in exterior environments. It cures into a closed‑cell, water‑resistant support that performs well through seasonal temperature swings. As with any repair, longevity also depends on site conditions and proper drainage.
How is sidewalk leveling priced in Woodstock, IL?
Pricing generally depends on how many panels need lifting, how much elevation change is required, and whether void filling or joint sealing is needed. A brief site evaluation identifies the scope and provides a clear estimate. Our team assesses most small residential sidewalk projects quickly.
Do I have to replace a sinking sidewalk?
Not usually. Raising settled panels with polyurethane is far less invasive than demolition and replacement and avoids long cure times. Concrete raising can deliver a clean, level surface while preserving adjacent landscaping and hardscape.
