Sinkholes in Florida
Sinkholes are often caused by issues stemming from damaged or corroded sewage pipe and drain pipes. They are a clear indicator that there is an issue underground. Florida sinkholes may appear overtime as the drain pipes underground begin to erode. This is why our underground utility experts emphasize the importance of pipe maintenance.
What is a sinkhole?
According to the United States Geological Survey, a sinkhole is defined as a “depression in the ground with no natural surface drainage”. This means that any water collected above a sinkhole will drain into the rocks beneath the surface.
The USGS explains that sinkholes form when these rocks are made of minerals that are soluble in water, usually limestone or evaporites like salt. As the water from the surface makes its way down it dissolves some of the minerals away, creating holes and and cracks. With time, the soil and sediments above the cracks and holes begin to slump downwards and therefore a sinkhole is formed.
Florida sinkholes come in many forms. In fact, there are three major types of sinkholes- solution, cover-subsidence, and cover-collapse. Below we will break each sinkhole down and explain what makes them different.
Solution Sinkholes: These type of florida sinkhole occurs where the rock is exposed at the ground surface or only has a thin covering of soil. These may appear as dips in the streets that are filled with water.
Cover- subsidence sinkholes - These types of sinkholes happen when the overburden is sandy and doesn’t stick together well. As the hole underneath forms, the, the sediments will sink down, eventually causing the surface to cave in.
Cover- collapse sinkholes - According to the USGS, if the overburden is made up of a lot of clay. Then the sediments will stick together more. When the weight becomes too much to bear, the surface layers will eventually give in and collapse. Cover collapse sinkholes are usually the most difficult to detect since they tend to grow underground without any visible signs on the surface. Worst of all, this type of sinkhole will usually collapse without warning.
Why are sinkholes so common in Florida?
Something we stand by is to prevent the damage before it happens. Yes, even sinkholes can be prevented. Sinkholes are formed underground and can at times show obvious signs before they are seen on the actual surface. Unfortunately, there are no guaranteed ways to determine if there is a sinkhole forming however, there are some ways you can tell if something is happening underneath the surface.
According to the National Geographic sinkholes are common in areas where groundwater can naturally dissolve the rocks below the land surface. Just last year about a dozen sinkholes were reported in Florida.
As previously mentioned, there are some obvious signs of sinkholes appearing. However, in other cases it may not be so clear. Always consult the help of an expert when determining if your home is at risk.
