How long does concrete leveling actually last?

By Sarah Etler - 9/30/22, 6:26 AM

You want to make sure you invest in a concrete repair that will stick around for good. But how long can concrete leveling keep your sunken concrete in its proper place?

Nothing lasts forever, and concrete leveling is no exception to that rule. But even though your lifted concrete won’t stay put for the rest of time, the good news is that it will last a really, really long time when the repair is done correctly.

A-1 Concrete Leveling has been lifting unlevel concrete slabs for over 30 years, so we’ve seen how durable and effective concrete leveling can be. In fact, some of the first jobs we ever leveled are right where we left them!

We warranty our work for 3 years, but the reality is that leveling your concrete can last a lot longer than that. As long as the soil or other sub-material under your leveled concrete stays intact, so will your level concrete. 

Concrete leveling can last for the life of the concrete itself.

How Long Does Concrete Leveling, or Foam Jacking Last?

This article will give our take on why concrete leveling can last so long, why we can’t control natural resettling, and how you can prevent resettling after a slab is lifted.

Why Concrete Leveling Can Last So Long

Most concrete leveling customers typically don't have a problem with the concrete itself, but rather a problem with the soil, backfill, or gravel underneath their concrete. When these materials settle or wash out, they take the concrete slab with them. 

During a concrete leveling repair, we drill through the section of sunken concrete and replace the soil or substrate material that settled or washed away with our injected leveling compound. That material spreads out underneath the section, fills up any voids, then lifts the concrete back into place.

The reason concrete leveling can last so long is that if the material underneath our injected material is done settling, then our material won't go anywhere either.

Uncontrollable Natural Settling

Natural settling around newer concrete is a factor that we cannot control.

The materials under newer concrete slabs or around new construction usually have not had the necessary time to settle naturally. 

Most of the time it takes your home 5-10 years for this natural settling to take place. This is why we don’t offer a warranty for concrete around homes less than 5 years old. There is nothing anyone can do to stop it from continuing to settle if it hasn’t on its own already. 

For this reason, in most scenarios, it makes sense to level concrete over replacing it. If you replace your concrete, you will disturb the soils underneath the concrete being replaced which increases the likelihood of your concrete settling again. Concrete leveling injects on top of the soil that has already had time to settle.

While there is nothing to be done about natural settling, what you can control are other factors that impact the longevity of concrete leveling, like water flow and animals. 

Controllable Factors 

Resettling, when not caused by natural settling and soil compaction, can be controlled by regular maintenance and attention to the following factors:

Water Flow

When water has access to the underside of a concrete slab, it can wash away the important sub-material that’s holding up both the slab itself and the extra material used to lift it back into place. Over time, this erosion of the sub-material gives space for the slab to sink back down. 

If your slab is in an area where water is constantly flowing around or under it, your repair may need to be revisited.

How to Prevent Water Impact

 
  • Backfill Soil

To prevent erosion from impacting your level slabs, you can backfill the exposed edges of the concrete with topsoil as a part of your regular landscaping maintenance. Adding extra material helps prevent the void from reappearing.

  • Reroute Drainage

In addition, it’s a good idea to reroute downspouts and other sources of drainage, like overflowing gutters, away from your concrete slabs, which will cut down on the flow of water and erosion in the area altogether. 

  • Caulk Breaks

Caulking is also a method to prevent water from affecting your level concrete. If your concrete has cracks or expansion joints, water can enter through them and erode the substrate. Caulking these areas allows the water to move over a break instead of seeping through it.

Learn more about concrete caulking.

Animals

If a family of pests moves in under your concrete slab, you’ll likely have problems with your concrete resettling. Animals burrowing in the soil underneath cause voids to open up and create weak spots where the concrete is unsupported and can sink again.

This can be prevented by keeping an eye out for animals like chipmunks and making sure they don’t make a home under your concrete.

Now what?

After learning more about concrete leveling’s durability, you now know that it can be a really useful tool for creating long-lasting, level concrete.
