Sinkholes are a naturally occurring feature that can form in areas underlain by carbonate geology. They can be destructive and dangerous, and expensive to repair. For those construction managers looking to build in areas underlain by carbonate geology, it is always important to determine if sinkholes are present prior to beginning a project.
What Causes Sinkholes?
Typically, sinkholes tend to form where either surficial stormwater collects in poor drainage areas or below ground where underground pipes leak. Sinkholes are caused by infiltrating water that intercepts open voids and cavities in the bedrock. Prior to opening at the ground surface, a void forms immediately above the rock surface. Over time and after repeated storm events, the void grows towards the surface as the overburdened soils erode into the underlying bedrock. The highest risk for sinkhole activity is typical during construction when drainage patterns change and the stormwater cannot be controlled. Sinkholes can also be caused by rock blasting that may be required for construction.
Signs Of A Sinkhole
There are some signs that you should watch out for that might indicate a sinkhole on your property. These can include:
- A surface depression forms on the ground surface that is circular in nature.
- Ghost lakes
- Shifting ground causes windows and doors not to open properly.
- Lack of water supply to your house
These are just a few signs, but they are early signs and they may save your project and prevent future damage.
Geological Surveys & Sinkhole Repair
Geological surveys are one of the easiest ways to determine if there is a sinkhole before you begin any project. The right company can conduct testing to see if there is a sinkhole or any other geological threat present. It is always best to ensure that your property is ready for the building before you begin and that the substrate is going to be able to support the structure that is going to be built on it.
