Concrete Leveling

Sunken or uneven concrete does not always need to be replaced. We lift and level settled slabs in Anchorage at a fraction of the cost of full replacement.

Why Concrete Slabs Settle in Anchorage

Settlement is one of the most common concrete problems in Anchorage and the surrounding areas. The primary cause is Alaska's frost cycle. As the ground freezes and thaws repeatedly, soil compacts and shifts beneath slabs. Over time, voids form under the concrete and the slab settles into those voids.

Poor drainage that allows water to erode fine soil particles out from under a slab is another common cause. So is inadequate compaction during the original installation. Whatever the cause, a settled slab creates an uneven surface, water ponding at the low point, and trip hazards where panels are no longer flush.

The good news is that when the slab itself is still structurally sound, meaning it has not broken into multiple pieces, leveling can restore it to a usable surface for significantly less than replacement.

How We Level Concrete Slabs

We use mudjacking (also called slabjacking) to lift settled concrete. The process involves drilling small holes through the existing slab, pumping a slurry material under pressure into the void beneath, and letting that material fill the void and lift the slab. Once the slab reaches the correct elevation, the holes are patched.

For slabs with drainage issues contributing to the settlement, we also address the drainage as part of the project to reduce the chance of the problem recurring.

If the assessment shows the slab is too damaged for leveling to be effective, we will tell you honestly and provide a concrete replacement option instead. We do not push leveling when replacement is the right answer.

Common Surfaces We Level

  • Driveway panels that have settled below the garage apron
  • Sidewalk sections that have heaved or sunk unevenly
  • Patio slabs that have settled toward the house
  • Garage floors with settled sections near doors or drains
  • Front entry steps and walkway panels
  • Commercial parking lot and loading area panels

We also offer concrete steps and stair work if your entry stairs have settled alongside your walkway. Call us or visit our home page to get started with a free estimate.

Frequently Asked Questions

What is concrete leveling?⌄
Concrete leveling, also called mudjacking or slab lifting, is a process that raises sunken or uneven concrete slabs by pumping a material beneath them to fill voids and lift the slab back to its original position. It is typically faster and less expensive than full slab replacement when the slab itself is still structurally sound.
Is concrete leveling a permanent fix?⌄
Concrete leveling can be a long-term solution when the underlying cause of the settlement is addressed. If a slab sank due to a one-time soil event or compaction issue that has since stabilized, leveling can last for many years. If ongoing erosion or drainage issues caused the settlement, those need to be corrected along with the leveling work.
When should I choose leveling over replacement?⌄
Leveling is usually the right choice when the slab has not cracked significantly, the settlement is limited to a few panels, and the sub-base conditions are still repairable. If the slab is broken into multiple pieces, has widespread cracking, or has settled by more than 2 to 3 inches, full replacement typically delivers a better outcome.
