Alabama Sinkholes and Nichols/Grout Tech
Sinkholes in our area are nothing new, but aside from being a nuisance, they can be extremely destructive. A sinkhole can quickly appear and, just as quickly, become large enough to damage property and endanger people. According to the Geological Survey of Alabama, sinkholes are the number cause of land subsidence. Subsidence is the sinking of soil, usually due to natural causes under the surface.
A large portion of Alabama is resting on a surface of limestone. Limestone is easily worn away by water, causing the formation of underground caves and sinkholes. There is a section of Northern Alabama, in Morgan County, that has an area peppered with sinkholes over four miles long. The largest sinkhole in the state is located in Shelby County. The Golly Hole near Calera, AL is over 100 yards in diameter and is over 120 feet deep. Fortunately, it occurred in a rural area and no one was injured and no property was damaged when it opened.
If a sinkhole opens near you, there are some steps you can take.
- This is the most important step: Place barriers and other warning signs around the sinkhole. This is to protect others and to protect yourself against liability claims.
- Contact your insurance company.
- Contact Nichols/Grout Tech to inspect the sinkhole and determine the steps needed to repair the damage.
- If the sinkhole is impacting public property, roads, or the safety of others, you may need to contact your local government.
Taking these steps will help make sure that others are safe and that you are protected from any liability issues.
Nichols/Grout Tech Can Help With Your Sinkhole
In early 2016 a sinkhole developed within the driveway of a residence. Through geotechnical investigations, it was determined this was one of a number of sinkholes, which are likely connected to each other. Working directly with the homeowners, insurance company, geotechnical engineers, and utility contractors, our team of sinkhole experts at Nichols/Grout Tech remediated the primary sinkhole.
This was accomplished by removing soils in a circular pattern around the sinkhole, which had a total diameter of approximately 40 feet, with the soils removed for approximately 10 feet in depth. After removal, geogrid and filter fabric was placed at the bottom of the excavation, soils were replaced in 8-inch lifts and compacted to approximately 98%.
Once our repairs were completed, the sinkhole stopped growing and the surrounding area was stable and secure. Contact the sinkhole professionals at Nichols/Grout Tech if you have a sinkhole on your property. Even what appears to be a small hole can be hiding a much larger problem under the surface that can cause serious damage and injury.
