Ground Penetrating Radar (GPR) is a form of radar which is designed for subsurface imaging. Its radar can be used to locate underground utilities and is a non-invasive and non-destructive method of surveying.
The Radar works by transmitting energy into the ground or other solid surface (soil, rock, concrete, wood, etc.). The energy transmitted then reflects back and the energy variations received are processed and displayed to the operator on a screen, showing the possible target in the ground. GPR mapping can detect the following:
Metals
Plastics
Concrete
Voids in the ground
Underground tanks
Please note: GPR mapping will not work in detecting objects and utilities behind metallic objects, such as reinforced concrete. Heavy clay soils and water with high mineral content ("hard water") will inhibit the ability of the GPR equipment.
GPR surveys can help prevent utility damage and decrease your overall project cost and are an excellent way of saving money.
Electronic Mapping and Tracing
By using a CAT and Genny, we can provide you with the exact location of all electrical cables on site. When used in conjunction with a GPR, this allows us to give you a precise location of all the utilities on site, including electrical cables, drainage runs, gas lines and telephone lines. A CAT can also be used to detect a Sonde, allowing drainage runs to be quickly and accurately traced.

Scaled Plans
Just Surveys can produce scaled plans as required to show the location of all underground utilities.Verification to PAS 128The above utility mapping works to achieve a Type B specification on the PAS 128 specifications. To achieve a Type A specification, the exact locations of the utilities must be verified by exposing them. Vacuum Excavation is an invasive but non-destructive technique, allowing test trenches to be dug without the risk of damaging the utility. Vacuum Excavation is SAFE method and around 50-100% faster than conventional hand digging. In addition, this aids in preventing dangerous and costly utility strikes.
