4 Reasons To Choosing Ground Penetrating Radar For Finding Old Septic Tanks

Posted on

Old septic tanks are often left in place underground when replaced with newer models rather than being excavated and removed. This leads to large voids in the soil that can collapse and create a sink hole, especially with the weight of something like a building pressing down on the empty spaces. These four reasons will convince you that it's worth the cost to hire a professional for ground penetrating radar scanning.

There's No Need for the House

Most non-destructive methods for finding septic tanks require you to know where the sewage pipe leaves the house served by the system. If the house is long gone and there's no visible pipe sticking up from the ground, a method like ground penetrating radar is your only choice. The professional running the scanner can cover large areas to find the faintest signs of abandoned and forgotten underground structures.

You Can Find Other Structures with One Scan

Concerned about buried fuel tanks, natural voids, and underground springs ruining a perfectly good home building site? The same radar scan used for checking septic equipment can also reveal any other type of buried material at the same time. Even if you don't find a septic tank, you may discover half a dozen other problems that convince you to relocate your home site or even invest in a different property.

You Get to Skip the Messy Excavation

When you're not sure if a septic tank even exists on the property in question, you don't want to waste a lot of hard packed soil by digging around endlessly to see what you find. While most people think that using a backhoe is the only affordable way to find old septic equipment, ground penetrating radar can cost less in the long run if you consider all the work it takes to recover from excavation. You could end up with serious drainage and erosion problems after digging around in the yard, while a silent and quick radar scan leaves everything intact.

The Scan Picks Up Almost Any Material

Finally, you'll get the best results with ground penetrating radar over other types of underground scans because the signal detects both metallic and non-metallic objects. This makes it useful for locating more modern plastic and concrete septic tanks, which are often missed with metal detecting scans. The results returned from the radar scan are also clearer and easier to understand than the readings produced by heat-dependent infrared imaging.
