Ground penetrating radar (GPR) is a technology that allows you to see objects underground. Used for locating utility lines, septic systems, underground storage tanks and voids, old building foundations, and other structures, it is superior to traditional electromagnetic locating in some conditions because it can detect both metallic and non-metallic objects up to 12 feet underground, or even much deeper in some soil conditions.
Numerous hazards lurk underground creating potential for serious accidents, injury to workers, construction delays and unanticipated expense.
It’s vital for utility locators to be able to “see” everything that’s underground. Traditional locating methods may not detect non-metallic and non-conductive objects such as PVC pipes, cables with broken or damaged tracer wires, abandoned utilities, conduits containing asbestos, concrete sewer and stormwater systems, and old burial sites.
GPR scanning is also beneficial in identifying different utilities that are buried close together. It can reliably estimate the depth of utility lines, allowing for better mapping of underground features. It is often used for planning the installation of new utilities.
In addition to identifying subsurface structures, ground penetrating radar can detect soil disturbances such as previous excavation sites and trenches.
