Benefits of GPR
Ground penetrating radar is a non-destructive way to see what's beneath the surface. It has a wide range of applications, including archaeology and construction.
Utility Locating
The most important benefit of GPR is that it is able to locate underground utilities quickly and accurately. Having this information can save contractors time and money by not having to cut through underground utilities before they start working.
It also allows them to find rebar, post-tension cables, and other structures that aren't visible from the surface. This makes it easier to work safely and efficiently, especially on jobs where there is limited access to the site.
Search and rescue
Using continuous signals, GPR can detect movement that could help rescuers find victims of landslides or building collapses. These signals can be sent at up to one thousand times per second and are ultra-sensitive, so they may even pick up shallow breaths or small motions.
Cemetery mapping and grave location
Another common application of GPR is helping researchers map out cemeteries or locate burial grounds where no records exist. The data can also be used to identify buried artifacts and other remains, which is invaluable when archaeological excavations are underway.
Structural assessments
Bridge decks are another popular target for GPR, enabling engineers to analyze structural damage and determine whether remediation is necessary. This type of technology is particularly useful for assessing the extent of voids and cracking that can result from concrete spalling, which can help engineers identify issues and design more cost-effective repair solutions.
