Concrete is a durable and versatile building material, but it’s not immune to damage. Over time, even the most well-poured concrete surfaces can crack, sink, or become uneven due to natural wear, soil movement, and weather exposure. For property owners in Long Island, Brooklyn, Queens, and The Bronx, staying ahead of these issues is key to preserving curb appeal, preventing trip hazards, and avoiding costly repairs.
At The Mudjacking Contractor, we’ve helped countless homeowners and businesses maintain solid, safe concrete surfaces. This blog breaks down the most common concrete issues, signs to watch for, and proactive steps you can take to avoid long-term damage.
1. Problem: Concrete Settling (Sunken Concrete)
What It Is
Concrete settling occurs when the ground beneath a slab becomes unstable. This instability causes the slab to sink unevenly, leaving noticeable dips, cracks, and tripping hazards. It’s especially common in areas with shifting or poorly compacted soil—like many parts of the New York City metro region.
Signs of Concrete Settling
- Uneven or sloped driveways, sidewalks, or patios
- Cracks forming around the sunken area
- Gaps between concrete slabs and adjacent structures
- Puddling water in low spots
Prevention & Repair Methods
- Proper Drainage: Ensure your property slopes away from structures to avoid water pooling under slabs.
- Soil Compaction: Before pouring new concrete, make sure the base soil is compacted properly.
- PolyLevel Injection: If your slab is already sinking, our PolyLevel (poly foam concrete leveling) method is ideal. It lifts concrete back into place with minimal disruption, perfect for tight urban settings like Brooklyn and Queens.
2. Problem: Concrete Cracks
What It Is
Cracks are among the most common concrete issues and can appear due to shrinkage, freeze-thaw cycles, soil movement, or excess load. While some hairline cracks are cosmetic, others may signal deeper structural problems.
Signs of Cracking
- Spiderweb or hairline cracks across the surface
- Larger, jagged cracks that grow over time
- Cracks with uneven slab elevation (may indicate settling)
- Cracking near joints or corners
Prevention & Repair Methods
- Control Joints: Installing joints during pouring helps guide natural cracking along planned lines.
- Sealing and Maintenance: Regularly seal your concrete to protect it from moisture and the freeze-thaw cycle, especially critical in The Bronx where winters can be harsh.
- Crack Injection & Sealing: For existing cracks, we offer epoxy or polyurethane injection, depending on the severity.
3. Problem: Soil Erosion Under Concrete
What It Is
Erosion washes away the base soil supporting your concrete, often due to poor drainage, heavy rainfall, or nearby landscaping. Once the sub-base is compromised, the slab becomes unstable and prone to sinking or cracking.
Signs of Soil Erosion
- Voids or hollow sounds under the concrete when tapped
- Rapid cracking or sinking after a heavy rain
- Visible gaps at the slab’s edges
Prevention & Repair Methods
- Downspout Extensions: Direct water away from concrete surfaces to avoid soil displacement.
- Regrading Landscape: Adjust slopes to promote natural runoff.
- Void Filling with Poly Foam: Our poly foam leveling process fills voids and re-stabilizes your slab from beneath without excavation.
4. Problem: Freeze-Thaw Damage
What It Is
During the winter, moisture in and around concrete can freeze, expand, and cause the surface to crack or flake. This is a common issue throughout Long Island and The Bronx, where winter temperatures fluctuate frequently.
Signs of Freeze-Thaw Damage
- Peeling or flaking concrete surfaces (spalling)
- Scaling or surface discoloration
- Cracking that appears after winter ends
Prevention & Repair Methods
- High-Quality Sealants: Use water-repellent sealants before winter begins to minimize moisture penetration.
- Proper Drainage Systems: Install drainage solutions to prevent water from pooling and freezing on slabs.
- Surface Refinishing: If spalling has already occurred, resurfacing with concrete overlays can restore appearance and integrity.
Why Proactive Concrete Care Matters in NYC’s Boroughs
Each of New York City’s boroughs brings unique environmental and structural challenges:
- Long Island: Sandy and clay-heavy soils often lead to shifting and erosion.
- Brooklyn: Dense urban infrastructure and old buildings require non-invasive solutions like poly-level foam.
- Queens: A mix of residential and commercial zones with varied soil types and exposure.
- The Bronx: Rolling terrain and harsh winters make poly foam concrete leveling a practical and long-term solution.
By understanding your local terrain and acting early, you can prevent small concrete issues from turning into expensive repairs.
