Subsurface Utility Mapping
Subsurface utility mapping is the science of mapping subsurface utilities utilizing non-invasive geophysical technology and vacuum excavation (soft dig) equipment.
SurvTech uses a combination of ground penetrating radar (GPR) and electromagnetic (EM) technology, also known as radio detection, to horizontally locate subsurface utilities.
Our subsurface utility locating personnel are equipped with the following equipment:
GSSI Utility Scan DF (Dual Frequency – 300 & 800 MHz)
GSSI SIR 4000 GPR Cart (300 & 400 MHz)
Radio Detection (RD) 4000 & 8000 Locators
Metrotech Vivax Locator VLocML2 Locators
ERI is used to locate objects much deeper underground by using the Super Sting R8/IP ERI System.
