Driveway Leveling: The 4 Best Methods

The Top 4 Driveway Leveling Methods 

When choosing a driveway leveling technique, it’s important to consider how it addresses the root cause: unstable soil. Driveways often crack and sink because the ground beneath them shifts or erodes, unable to bear the weight. 

For repairs to last, the soil must be stabilized along with leveling the concrete. The leading driveway leveling methods vary in their approach to reinforcing the soil. This guide examines how the top four techniques—mudjacking, polyurethane foam injection, replacement, and asphalt overlay—deal with the underlying soil issues behind a sinking driveway. Analyzing the soil stabilization methods used by each process can help determine the best long-term solution for your driveway. 

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 is 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 is 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 is 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 Level My Driveway with DIY Repairs? 

The Top 3 Tips for Preventing Worsening Damage 

While cracks and unevenness are common driveway problems, you can take proactive steps to protect your concrete and maintain its integrity, including: 

• Weight Distribution: Avoid parking heavy vehicles in the same spots repeatedly. The constant weight can cause cracking and sinking. 
• Control Water Runoff: Direct water drainage away from the driveway. Make sure downspouts and landscaping don’t allow water to pool on or near the concrete. 
• Vigilance, Repairs, and Maintenance: Check for early signs of damage. Look for minor cracks or shifting and address them quickly before they worsen. Consult concrete repair professionals at the first sign of a problem.

FAQs

What are signs my driveway needs leveling?

Indications your driveway may require leveling include cracks, slabs that are higher or lower than others causing unevenness, water that pools instead of drains, and tripping hazards from raised or sinking sections. If you spot any of these problems, reach out to Baker’s Waterproofing for a free inspection and estimate. Our experts can evaluate your driveway’s condition and advise if leveling could help resolve these issues. 

How long does driveway leveling last?

Driveway leveling, particularly with polyurethane foam injection, can provide long-lasting repairs for uneven concrete. This method not only levels the driveway surface but also reinforces the soil underneath, preventing future sinking. However, longevity depends on fixing the root problems like poor drainage. When the causes of unevenness are properly addressed, leveling offers an effective, lasting solution for concrete problems. Consult the experts at Baker’s Waterproofing to determine if leveling is the right choice for maximizing your driveway’s lifespan. 

What is the cost to level my driveway?

Driveway concrete leveling costs vary depending on the amount of damage, method used, labor, materials, permits, and other factors. Most driveway leveling projects range from $800 to $4,000+. The most accurate pricing for your specific driveway can be determined through a free inspection and no-obligation estimate from Baker’s Waterproofing. Our experts will assess your concrete, recommend solutions, and provide tailored quotes based on your driveway’s unique needs.
