Concrete Driveway Leveling: The 4 Best Options for Repair

The significance of your driveway in daily life may be underestimated, but it plays a more crucial role than you might think. Being constantly exposed to the weather means your driveway is prone to wear and tear, leading to issues like sinking and uneven surfaces.  

For homeowners, a driveway that’s cracked and uneven becomes a serious tripping hazard, can decrease the property’s value, and cause damage to vehicles. Concrete leveling is the solution to these problems, involving the injection of materials beneath the concrete to restore it to its original level. 

This guide will explore various methods to repair and level your driveway, detailing the advantages and disadvantages of each and explaining how local experts in concrete leveling can assist you. 

Top 4 Ways to Level a Driveway 

Driveways require a solid foundation—namely, the soil beneath them—to endure over time. The soil may settle or erode, creating gaps that the concrete slabs can sink into.  

To repair or level your driveway effectively, stabilizing the underlying soil is essential. Without addressing this, the same issues will persist. Considering the soil’s stability is crucial when selecting the most suitable driveway repair technique for your house. 

1. Mudjacking

What it is:

Also known as “slabjacking ,” mudjacking uses a slurry formula (cement, water, soil, and sand mixture) which is pumped underneath sunken concrete to raise it back to level.  

Pros:

  • Fills up gaps and forms a sturdy base for concrete  

Cons:

  • Requires large holes  
  • Does not fully fill voids  
  • Difficult to control material flow  
  • Long cure time  
  • Cannot use concrete for several days  
  • Added weight on top of soil  
  • Temporary solution 

2. Polyurethane Foam Injection 

What it is:

Also known as “polyjacking,” “polylifting,” or PolyRenewal™ (our method), Polyurethane injection involves injecting a specially formulated foam material under the concrete which expands and lifts the slab.  

Pros:

  • Lightweight foam  
  • Smaller drill holes  
  • Completely fills voids  
  • Cures quickly (within 30 minutes)  
  • Environmentally friendly 
  • Stabilizes underlying soil  
  • Smooth finish  
  • Lasting results  

Cons:

  • Slabs may not be 100% level  
  • Visible cracks may remain  
  • Variable soil conditions can impact its stability  

3. Replacement

What it is:

Driveway replacement involves demolishing old slabs and repouring cement  in its place which may be necessary with severely damaged, crumbling, pitting, flaking, or staining concrete  

Pros:

  • Brand new concrete slabs  
  • Smooth finish  

Cons:

  • Requires heavy equipment and excavation  
  • Extended downtime (long cure time and inability to use driveway)  
  • Heavy cement on top of unstable soil  
  • Future soil and slab settlement likely  
  • Expensive (sometimes costing $5,000 or more)

4. Asphalt Overlay  

What it is:

Asphalt overlay is used for minor sinking and cracks.  An epoxy and sand slurry used to fill voids and level the surface on top.  

Pros:

  • Relatively inexpensive  
  • Less disruptive method  
  • Can be used to fill potholes  
  • Smooth, consistent finish  

Cons:

  • Added weight to soil  
  • Worsens underlying issues  
  • Not suitable for severely damaged slabs  
  • Concrete’s expansion joints can cause shifting asphalt over time, leading to cracks and bumps  

Can I Fix My Sunken Driveway Myself? 

These approaches may seem simple, and indeed they are—for experts. 

We advise against attempting concrete driveway leveling on your own. The necessary techniques demand specific tools and materials, acquisition of which can be challenging and expensive.  

Operating heavy machinery and handling these materials can pose risks without appropriate expertise. Entrust the substantial work to professionals.

3 Ways to Prevent Driveway Cracks from Worsening 

While it’s not unusual to see cracks and uneven surfaces in driveways, there are several strategies to prevent and safeguard your concrete: 

  • Weight Distribution: Avoid heavy loads on the driveway—such as vehicles continuously parked in the same spot—that could cause pressure points, leading to cracking or sinking.  
  • Proper Drainage: Make certain that downspouts and nearby landscaping effectively channel water away from your driveway. 
  • Regular Inspection: Routinely check your driveway for minor cracks or indications of shifting. Quickly tackle these problems by consulting with local concrete professionals to avert major issues.

FAQs

The unevenness or sinking of driveways can be attributed to a variety of factors, such as the erosion of soil, inadequate soil compaction prior to installation, the gradual settling of the ground over time, and problems with water runoff or drainage. These issues may cause spaces to form under the concrete, resulting in parts of the driveway sinking or becoming uneven. 

Indications that your driveway might require leveling include noticeable cracks, an uneven surface where parts of the driveway are not level with others, water accumulation, and potential tripping hazards. Should you observe any of these conditions, it’s advisable to reach out to Tar Heel Basement Systems for a complimentary inspection and further information on the advantages of driveway leveling.

The cost to level a driveway is influenced by various factors, such as the severity of the damage, the repair method selected, and the expenses associated with labor, materials, and permits.
