Concrete lifting is a cost-effective solution for fixing sunken slabs, but concrete lifting maintenance is key to ensuring the repair lasts for decades. While polyurethane foam lifting (polyjacking) is one of the most durable concrete leveling methods, poor upkeep can lead to erosion, cracking, and resettling over time.
At Slab-Jack Kings, we don’t just lift your concrete—we help you protect your investment. By following the right concrete lifting maintenance steps, you can extend the lifespan of your repair and avoid costly future fixes.
Why Maintenance is Crucial After Concrete Lifting
While foam concrete lifting (polyjacking) is one of the most durable methods for leveling sunken slabs, improper maintenance can shorten its lifespan.
Without proper care, your lifted concrete could be at risk of:
- Soil erosion, which can cause resettling
- Cracks, leading to water infiltration
- Pest infestations, weakening the foam underneath
- UV damage, breaking down exposed foam
Essential Maintenance Tips for Lifted Concrete
Prevention Tip #1: Stop Soil Erosion Around the SlabProblem: One of the biggest threats after concrete lifting is soil erosion. If water washes away the soil beneath the slab, the concrete might settle again. Solution:
|
 |
Prevention Tip #2: Protect the Foam From UV ExposurePolyurethane foam is highly durable, but it breaks down under direct sunlight. If the foam is exposed along the slab edges, it can lose its hydrophobic properties, causing it to degrade over time. Solution:
|
|
Prevention Tip #3: Maintain Proper DrainageWater is the #1 cause of slab settling. Poor drainage can lead to soil washout and the formation of voids beneath the slab. Solution:
|
 |
Prevention Tip #4: Seal Cracks and Joints to Prevent Water DamageEven small cracks can allow water to seep under the slab, causing soil movement and weakening the foundation. Solution:
|

Prevention Tip #5: Watch for Signs of PestsSome pests, like ants and rodents, may burrow into the foam beneath the slab, creating voids that can cause resettling. Solution:

FAQs About Concrete Lifting Maintenance
How often should I perform concrete lifting maintenance?
You should inspect and maintain your lifted concrete at least twice a year—before winter, after heavy rain and in the spring time. Proper concrete lifting maintenance helps prevent cracks, pooling water, and soil erosion.
Can lifted concrete sink again without proper maintenance?
Yes, if concrete lifting maintenance is neglected, issues like drainage problems and soil erosion can cause the slab to sink again. Regular inspections and upkeep help prevent resettling.
What are the most important steps in concrete lifting maintenance?
Key maintenance steps include:
- Ensuring proper drainage to prevent soil erosion
- Sealing cracks to block water infiltration
- Checking for exposed foam and covering it to prevent UV damage
- Keeping pests away by maintaining landscaping and sealing entry points
How can I prevent water from damaging my lifted concrete?
Good drainage is crucial for concrete lifting maintenance. Keep gutters and downspouts clean, install proper drainage, and ensure water flows away from the slab edges of the slab to prevent erosion.
How does pest control fit into concrete lifting maintenance?
Pests like ants and rodents can burrow into the foam beneath your slab, causing voids. As part of concrete lifting maintenance, keep landscaping tidy, apply pest control treatments, and seal entry points around the slab.
Does concrete lifting maintenance include cleaning?
Yes, gentle cleaning is part of proper concrete lifting maintenance. Use mild soap and water for general cleaning.
How does winter impact concrete lifting maintenance?
Freeze-thaw cycles can cause cracks and soil shifting. As part of concrete lifting maintenance, apply sealant before winter and ensure proper drainage to prevent issues caused by freezing temperatures.
How long does foam jacking last?
If you follow proper concrete lifting maintenance, your foam jacking repair can last 20 to 50+ years—as long as the concrete itself!
What should I do if my lifted concrete starts to crack?
Small cracks should be filled with high-quality concrete sealant. If cracks expand, consult a concrete lifting maintenance professional to prevent further damage.
