Underground voids can be caused because of material washout.
For the most part, underground void detection is all too common among those who handle concrete and more. In fact, void detection surveys tend to use Ground Penetrating Radar (GPR) to scan the actual area and determine the exact location and ultimate extent of any potential voids and sinkholes. The reality is, void detection that is installed underground is usually designed to form a risk prevention that actually has the intent of checking the ultimate integrity of the ground itself before moving or using any heavy equipment. Ultimately, if any remediation is necessary, underground void detection can help to locate that as well. Here are a few key things to understand when it comes to underground void detection and how it actually works.
The Actual Causes Of Underground Voids
There are some clear causes associated with the development of an underground void. In fact, sinkholes tend to be the most common cause. The reality is, besides sinkholes, underground voids can be caused because of material washout as a result of underground water movement that tends to carry material with it — usually in coastal areas. Ultimately, natural substances can also be carried in with the ground simply moving and shifting over time — leading to the potential for an underground void as well.
Detecting Sinkholes And More Using GPR
Fortunately, there are systems and technology that have been developed to help locate and detect sinkholes and other underground voids that may appear and cause damage. In fact, GPR typically works to ideally transmit an electromagnetic signal directly into the ground and record reflections immediately. The reality is, with GPR, reflections tend to be caused by any change in the below surface environment generally. Ultimately, detecting underground voids is made a lot easier by using GPR.
Bottom Line
At the end of the day, having the ability to detect underground voids can be incredibly useful, beneficial, and helpful overall. In fact, GPR is a great method of accurately, effectively, and efficiently detecting an underground void. This can easily help understand where an underground void is located and repair them as needed. The reality is, underground void detection is a key component to making sure that the ground is structurally intact so people can build on it without worry.
