Understanding the Causes: Why Concrete Settles and Unevenness Occurs

Uneven Concrete Can Be Frustrating and Unsightly, but Understanding the Common Culprits Can Help You Prevent Future Issues. Here’s a Breakdown of Some of the Most Frequent Causes of Concrete Settling and Unevenness:

Soil Issues:


  • Soil Erosion: Over Time, Water Runoff or Improper Drainage Can Wash Away Soil Beneath the Concrete Slab, Causing It to Lose Support and Sink.
  • Unstable Soil: Poorly Compacted Soil or Soil with Low Bearing Capacity Can Settle Over Time, Leading to Uneven Concrete Slabs.
  • Freeze-Thaw Cycles (Especially for Colder Climates): The Repeated Freezing and Thawing of Water in the Soil Can Cause the Soil to Expand and Contract, Putting Stress on the Concrete Slab and Potentially Causing Cracks and Unevenness.

Water Issues:


  • Improper Drainage: Water Pooling Around the Concrete Slab Can Seep Underneath, Softening the Soil and Leading to Settlement.
  • Leaking Pipes: Underground Leaks from Pipes or Sprinklers Can Erode Soil and Create Voids Beneath the Concrete, Causing It to Sink.

Construction Issues:


  • Improper Slab Preparation: Inadequate Compaction of the Subgrade Before Pouring Concrete Can Lead to Settling Issues Later.
  • Poorly Mixed Concrete: Concrete That Is Not Properly Mixed May Not Cure Evenly and Can Develop Weak Spots That Are More Prone to Cracking and Settling.

Other Causes:


  • Tree Root Growth: Tree Roots Growing Near Concrete Slabs Can Exert Significant Pressure, Causing the Concrete to Crack and Become Uneven.
  • Excessive Weight or Traffic: Concrete Slabs Not Designed for Heavy Loads Can Crack and Settle Under Excessive Weight or Traffic.

Spot the Signs: Identifying Uneven Concrete Around Your Property

Proactive Identification of Uneven Concrete Allows You to Address the Issue Early On and Prevent Further Problems. Learn to Identify Problem Areas and Address Them Proactively with Polyjacking Concrete Leveling. Here’s How to Identify Potential Problem Areas Around Your Property.

Start With a Visual Inspection: Walk Around Your Property and Take Note of Any Areas Where the Concrete Appears Uneven, Cracked, or Sloping Downwards. Focus on Common Areas Like Driveways, Walkways, Patios, or Pool Decks.


Use a Straight Edge: Place a Long, Straight Board (Like a Level) on the Concrete Surface. Any Gaps Between the Board and the Concrete Indicate Unevenness.


Measure the Difference (Safety Note: Be Careful While Walking on Uneven Surfaces to Avoid Tripping Hazards): Use a Ruler to Measure the Difference in Height Between the Highest and Lowest Points of the Uneven Area. Generally, Concrete Leveling Is Recommended for Areas That Have Sunk or Settled More Than ½ Inch.


Here Are Some Items to Take Note of on Your Visual Inspection:


  • Tripping Hazards: Have You Noticed Uneven Slabs That Have Created Tripping Hazards for Your Family and Guests?
  • Pooling Water and Drainage Issues: Do You See Puddles Forming on Your Driveway, Patio, or Walkways After Rain or Snowmelt?
  • Uneven Concrete Slabs: Do You Have Uneven Slabs? By Uneven We Mean: Tilted, Sloping, Sinking, Heaving and Settling Slabs Which Causes Them to Be Uneven.
  • Cracks and Fractures: Are There Cracks Developing in Your Concrete Due to Settling or Movement?

  • Door Issues: Do You Have Difficulty Opening or Closing Doors That Lead to Areas With Uneven Concrete? Settling Concrete Can Cause Misalignment of Doors and Windows

  • Initial Assessment: Our Team Starts by Conducting a Thorough Inspection of the Affected Area to Assess the Extent of the Concrete Settling and Determine the Best Course of Action.
  • Preparation: Before the Polyurethane Foam Injection, We Prepare the Area by Drilling Small (Dime-sized) Holes into the Concrete Surface Strategically Placed to Ensure Even Distribution of the Foam.
  • Foam Injection: Next, We Inject the Polyurethane Foam Mixture into the Pre-drilled Holes. The Foam Expands to Fill Voids Beneath the Concrete Slab, Lifting It Back to Its Original Position.
  • Monitoring: Throughout the Injection Process, Our Technicians Carefully Monitor the Foam Expansion to Ensure Precise Leveling of the Concrete Slab.
  • Cleanup: Once the Foam Has Fully Expanded and the Concrete Is Leveled, We Clean Up the Work Area, Removing Any Excess Foam and Debris.
  • Final Inspection: After the Polyjacking Process Is Complete, We Conduct a Final Inspection to Ensure the Concrete Is Properly Leveled and Stabilized.
  • Cleaning & Curing: Once Complete, the Technician Will Clean the Work Area. The Injected Foam Cures Completely Within a Short Timeframe, Allowing You to Use the Concrete Surface Quickly.

Considerations, Examples and Key Terms:

Numerous Methods for Concrete Leveling Are Available, But Polyjacking Stands Out Due to Its Unique Combination of Benefits, Making It Our Preferred Solution. 

Here’s a Quick Overview of Other Options:

  • Mudjacking (Slabjacking): Mudjacking Is Messier, Prone to Washout, and Requires Larger Injection Holes. Polyjacking Offers a Cleaner, Faster Alternative.
  • Slab Replacement: This Is the Most Expensive Option, Requiring Demolition of the Existing Concrete. Polyjacking Is Often Suitable for Use the Same Day, Saving You Time and Money.
  • Concrete Grinding: Concrete Grinding Only Reduces High Spots and Doesn’t Address Settlement. Polyjacking Lifts, Stabilizes, and Fills Voids to Prevent Future Settlement.
  • Self-Leveling Concrete: Offers Minimal Surface Improvement and Doesn’t Address Structural Issues Like Polyjacking, Which Can Prevent Future Problems.

Before After

Heave and Frost Heave: Upward Movement of Concrete Slabs Caused by Soil Expansion, Frost, or Tree Roots.


Settle, Settled, and Settlement: Downward Movement of Concrete Slabs Due to Erosion, Moisture Changes, or Improper Construction.


Slope and Slope Correction: The Slight Slant of Concrete for Proper Drainage. Adjusting This Slope Is Called “Slope Correction.”


Void and Void Filling: Empty Spaces Beneath Concrete Slabs. Filling These Voids Restores Support and Prevents Further Settlement. Polyurethane Foam Is a Common Solution for This.


Lateral Movement: The Sideways Shifting of Adjacent Slabs, Often Occurring as a Result of Leveling One Slab, Which May Necessitate the Leveling of Adjacent Slabs. Our Experienced Technicians Consider the Possibility of Lateral Movement While Assessing the Project to Ensure Evenness and Stability.


Curing and Curing Time: Allowing Materials to Reach Full Strength. Mudjacking Takes 24 Hours, While Polyurethane Foam Cures Within Hours.


Sealing: Applying Sealant to Protect Concrete from Moisture Penetration.


Expansion Joint: A Deliberate Gap Between Slabs to Allow for Movement Due to Temperature Changes. Sealing These Is Crucial.


Mudjacking (Slabjacking): Lifting Concrete with a Slurry Mixture. This Method May Require Repeated Applications Due to Potential for Re-Settlement.


Polyjacking: A Reliable and Long-Lasting Solution for Lifting and Leveling Concrete Using Polyurethane Foam. It Addresses Voids and Is More Cost-Effective Than Replacement.

Winter: 

To Ensure Long-Lasting Results, Concrete Leveling Projects Are Typically Paused During Winter Months When Frost Heave Can Potentially Cause Re-Settlement of the Leveled Concrete.


Heavy Rain:

Poses Risks to the Leveling Compound and Equipment, Hindering Proper Curing. If Heavy Rain Is Forecasted or Occurs During Your Scheduled Exterior Concrete Leveling Appointment, We May Contact You to Discuss Rescheduling. This Ensures That the Leveling Compound Can Cure Optimally Under Suitable Weather Conditions.

Get Ready for Your Assessment : Save Time and Ensure a Thorough Assessment


  • Clear the Area: Remove Furniture, Rugs, and Anything Blocking the Concrete Slabs (Interior) and Move Vehicles or Obstacles (Exterior).
  • Mark Areas of Concern (Optional): If You Have Specific Problem Areas, Mark Them with Washable Marker or Tape for Easy Reference During the Technician’s Visit.
  • Discuss Utilities: If You’re Aware of Any Underground Utilities Near the Concrete Slabs, Let Us Know During the Appointment. This Will Help with Planning the Repairs.


What Happens During the Assessment?


  • Our Technician Will Inspect the Slabs for Existing Damage, Assess Potential for Lateral Movement (See Key Terms), and Take Measurements for Leveling.
  • Pilot Holes (If Needed): To Determine Soil Conditions and Extensive Voids, We May Request Permission to Drill Dime-Sized Holes. These Holes Are Filled After the Assessment.
  • Feel Free to Ask Questions! Your Technician Is Happy to Answer Any Questions You Have About the Process.


Preparing for Your Repair:


  • Clear the Area Again: Similar to the Assessment, Remove Furniture, Rugs, and Anything Blocking the Slabs (Interior) and Move Vehicles or Obstacles (Exterior).
  • Mark Utilities (If Applicable): If You Haven’t Already Discussed Them, Mark Any Underground Utilities Near the Concrete Slabs Before the Repair Appointment.


What to Expect After the Repair:


  • Ready to Use (Generally): The Leveled Area Is Typically Usable Once the Repair Is Complete and the Cleanup Is Finished.
  • Curing and Care Instructions: Your Technician Will Advise You on Any Specific Curing Times or Post-Repair Maintenance Required for Your Project.


Maintaining Your Leveled Concrete:


  • Grading and Backfill: Maintain Proper Soil Grading and Backfill Around Your Foundation to Prevent Future Settling.
  • Gutters and Drainage: Ensure Your Gutters Function Properly and Are Directed to Lead Water Away from the Foundation.
  • Cracks and Sealants: Seal Expansion Joints to Prevent Water Infiltration and Potential Slab Movement.

Foundation Wall Cracks: Uneven Concrete Can Allow Water to Pool. If the Pooling Water is Entering the Basement You Might Have a Foundation Wall Crack.
