While you might not think of it at first glance, the cute, innocent-looking chipmunk using your porch as wintertime nut storage is actually putting your concrete at risk.
When burrowing pests move in under your concrete slabs, not only can they cause health and safety concerns, but they can also cause damage to your concrete.
Here at A-1 Concrete Leveling, we see multiple cases every day where animals make homes under concrete slabs, ultimately causing them to settle.
In this article, we’ll break down why exactly this is the case, what you can do about it, and which pests we have seen the most throughout our 30+ years repairing concrete.
Soil erosion is one of the main reasons that concrete slabs sink. If the soil under a concrete slab is removed or displaced, the slab on top will eventually settle down where the soil used to be.
Rodents and other burrowing pests are big culprits of soil erosion. As these animals dig away at the soil and burrow under a slab, they loosen and displace the soil that the slab is sitting on.
Over time, the concrete slabs sink as the loosened soil compresses back down or the burrowed voids give way.
As burrowing pests create voids, tunnels, and weak places under the slab, they’re removing and displacing the important material that holds the slab in place.
Concrete leveling can fill rodent holes under concrete, stabilize the slab in place of the loosened soil, and lift the settled concrete back up into the proper position.
The concrete leveling process works by first drilling small holes in the affected slabs, pumping a leveling compound underneath, lifting the concrete, then sealing off the drill holes.
It’s important to mention that concrete leveling is not a pest control method. Pests can still come back after leveling is done and cause your concrete to settle all over again if they are not properly removed and prevented.
We most often see these burrowing animals under settling concrete slabs:
Some less common but still relevant burrowing pests found under concrete are:
*Ants are commonly found burrowing under concrete, but their damage can be slow-going.
Now that you’re aware of the dangers that burrowing animals pose to your concrete, you should remove unwanted pests and take care of any damage left behind.
Leaving pest removal up to the professionals can be safer and help ensure that no animals come back to the concrete, potentially causing it to settle again.
Once the pest situation is under control, concrete leveling can fill the voids left behind by these animals while lifting and stabilizing your slabs at the same time.
