GPR surveys are mostly used for finding and mapping the network of underground services, underground storage tanks, archeological artifacts and a variety of buried objects.
The principle works around the propagation of electromagnetic waves thanks to a transmitter in the machine, the wave then bounces back on interfaces and discontinuities of the ground which then get picked up from the instrument's receiver as hyperboles.
So.Gest Ambiente offers a complete mapping service thanks to the gpr IDS Opera Duo.
Knowledge of the exact position of existing underground structure is crucial for the correct prosecution of any work. A GPR survey is an excellent choice to find any information necessary for the planned operations efficiently, safely and without any damage to the infrastructure, as the method is non-destructive.
At the same time of the GPR aquisition So.Gest Ambiente uses also other cable/pipe locators (particularly C.Scope MXL4 - MXT4) to nullify any ambiguity from the interpretation of the GPR radargram.
A typical GPR survey is made of the aquisition of data from a regular grid in order to scan the whole area to search. When the instrument intersect anything perpendicular to his movement the electromagnetic signal is deflected and seen in the screen as a peculiar hyperbole, which has to be interpretated then.
Searching for buried archeological artifacts and structure is perfect for the GPR methodology.
A GPR archeological survey, using a scrupolous grid pattern, is able to find objects and other anomalies on very different scales.
A GPR is able to find in the first layers:
ground anomalies and separations
voids, hollows or hidden rooms
And in depth:
area of interests for excavations
services, metallic or plastic ones
buried objects, uxo
