What causes sinking concrete slabs?

The problem isn’t your concrete, it’s the soil beneath. When the soil beneath your concrete compacts or washes out, it leaves voids into which heavy concrete slabs sink. These voids need to be filled in order to raise the sunken slabs back to level.

How soil causes concrete to sink:

Concrete starts out durable, rigid, and weighty, making it a great material for residential patios and driveways to warehouse floors. Over time, the level soil underneath the concrete begins to shift with changes in the moisture content in the ground. Soil movement causes voids under the concrete and because concrete is heavy, it starts to sink. Because it’s rigid and inflexible, it starts to crack. Soil movement occurs in a variety of ways, including:

  • Backfilled Soil: Loose soil that is backfilled when a home is built is often not well compacted and settles over time, resulting in one or more voids under the concrete.
  • Droughts & Soil Shrinkage: In droughts, the soils under your concrete shrink, causing voids, as well as cracks and crevices in the concrete.
  • Rainfall & Erosion: When it rains, water finds its way into and under concrete slabs, causing the soil to soften and weaken, or wash away, leaving voids.

Soil movement is bound to occur, but the damage sunken concrete leaves behind doesn’t have to be permanent. Trusted concrete leveling solutions can easily help resolve such issues.

The Best Alternative to Mudjacking and Slab Jacking

Mudjacking, or slab jacking, is a concrete leveling solution that requires the demolition and replacement of an entire slab of concrete, a procedure that is time-consuming and expensive, not to mention disruptive to the property. PolyLevel® two-part foam expands instantaneously upon injection beneath a settled slab. The injection holes that our contractors drill through the slab are small and much less noticeable than those required for a typical mudjacking procedure. During the injection process, PolyLevel® expands many times its original volume and gains density, forcing the sunken concrete back to its initial level. It takes only a matter of minutes for the polymer to expand and reach more than 90% of its firmness!
