Sinkhole Repair in Franklin, TN

How big do you think a sinkhole is? When you imagine a sinkhole, is it small enough to trip on, or is it large enough to swallow your entire home? The truth is both options are very real. Thankfully, the experts at United Structural Systems can repair sinkholes in Franklin, TN, so you don’t have to worry one way or the other.

What is a Sinkhole?

Imagine there’s a large rock underneath the soil around your home. When groundwater moves around that rock, it slowly erodes it. Eventually, that rock can dissolve entirely.

A large empty space, or void, is left behind when that happens. That means the soil that was originally above the rock no longer has any support. Inevitably, the soil will collapse to fill the empty space beneath. This collapse is a sinkhole.

How Do Sinkholes Form in Franklin, TN?

In Tennessee, the majority of the state rests on top of easily dissolvable limestone and dolostone bedrock. Heavy rainfalls followed by droughts are major contributors to sinkhole development. Improper grading can let water into the subgrade. Significant water leaks near the karst area can also cause sinkholes to form.

Sinkhole Warning Signs

If you’re concerned about sinkholes on your property, look for the big red flags first. Should you spot new or random depressions in your yard, ground cracks, and tilting trees or fence posts, a sinkhole may be forming.

If your foundation has suddenly formed cracks, or if there are visible holes in the ground, you might have a sinkhole on your hands already.

How We Repair Sinkholes

The first step is to excavate to expose the sinkhole’s throat where it enters the bedrock. Next, we choke the throat with proportionally sized stones and line the excavation with nongovernmental geotextile fabric.

Then, we backfill with clean #57 gravel to within a few feet of the surface, fold the geotextile fabric over the gravel and complete backfilling with previously excavated soil. Lastly, we consider rerouting or managing any water sources away from the area.

This proven method is referred to as an inverted cone filter repair.
