Sinkhole Repair in Clarksville, TN
When you think of a sinkhole, what size do you imagine it to be? Does your mind go straight to a simple trip hazard or something large enough to devour a house? In the end, both scenarios are possible. United Structural Systems is able to repair any sinkhole that forms due to Tennessee’s unique geology.
What is a Sinkhole?
To understand how sinkholes form, imagine that there’s a large boulder under the soil in front of your house. Groundwater slowly dissolves the boulder as water flows over it. After a long enough time, it can eventually dissolve completely.
If this happens, it leaves behind a lot of empty space, and this means that soil that was previously on top of the rock now has no support. As the soil is exposed to the elements, it will begin to crumble and fill the gap. This is known as a sinkhole.
How Do Sinkholes Form in Clarksville, TN?
Most of Tennessee’s land mass sits on bedrock composed of easily dissolvable limestone or dolostone. Sinkhole development can be exacerbated by heavy rainfalls that are followed up by droughts. Bad grading may allow water into the subgrade. Sinkholes could also form if water leaks occur in the karst areas.
Sinkhole Warning Signs
Be aware of the signs that indicate a sinkhole is forming on your property. Sinkholes could be possible if there are new or unrelated depressions found in your yard. You may also notice ground cracks, or you’ll see trees and fence posts leaning to the one side.
If your foundation has cracked suddenly, or you see visible holes in the ground, you may already have a sinkhole issue.
How We Repair Sinkholes
There are a few important steps in sinkhole repair. To expose the sinkhole’s throat, where it enters bedrock, the first step is excavation. The throat is then filled with appropriately sized stones. We then line the excavations with nongovernmental geotextile fabric.
Afterwards, we backfill the area with #57 clean gravel and cover the gravel with the geotextile material. Finally, we fill the hole with the previously excavated earth. Finally, to prevent the issue from returning, we will consider managing or redirecting nearby water sources.
This technique is known as inverted cone filter repair.
