GSSI Utility Locating Equipment

GSSI Utility Locating Equipment

Utility locators, construction professionals, environmental firms and land surveyors need to know about underground assets prior to digging and trenching efforts. Learn more about how our ground penetrating radar (GPR) utility systems help locate and map metallic and non-metallic underground utilities and subsurface characteristics.

Utility Locating Information

GSSI Utility Locating - Data Example 1

Locate and Map Underground Utilities

Contractors can mark out the depth and position of metallic and non-metallic pipes, and continuous plastic conduits such as gas and water lines, in real time using the GSSI UtilityScan products. GPR can enhance the overall understanding of subsurface targets and obstructions.

Taken at the GSSI utility test pit, this data illustrates 3 utility targets at various depths. These targets are metal, and this data was taken with the SIR 4000 and 400 MHz antenna. This data image highlights the marker input feature in the SIR 4000 control unit.

Locate Utilities with LineTrac

This data image was taken with the new UtilityScan and shows a target at 1m deep, target is electric utility with 60 Hz power detected. This data set highlights the LineTrac feature that is optional in the UtilityScan system.

Utility Locating - Data Example 3

Locate Duct Banks

Utilities encased in concrete and groupings of utilities can be located by using ground penetrating radar.

This 2D data set shows a duct bank with five utilities. Also shown is a well-defined excavation trench. This data was collected with the UtilityScan Pro with the 400 MHz antenna.

Identify Underground Voids

Construction professionals, engineers and transportation departments can identify and delineate voids under the surface of concrete and asphalt roadways with ground penetrating radar.

Data illustrates a well defined void underneath a reinforced concrete slab with an asphalt overlay. Note the small subsurface utilities in the bottom right of the data set. This data was taken with a SIR 4000 and 900 MHz antenna.

Utility Mapping Information

GSSI - Utility Mapping - Data Example 1

Map Underground Utilities

Construction professionals can use GPR to map underground utilities using 3D data collection techniques that accurately and easily define complex utility scenarios. Users can create utility asset maps for areas such as large street intersections.

Data illustrates a 3-dimensional view of a survey of existing and abandoned utilities presented in RADAN 3D. Note the broken linear feature that denotes an abandoned utility. Data collected with a 400 MHz antenna.

Subsurface Utility Engineering

Municipalities and engineers can take their utility mapping requirements to the next level with GSSI GPR. By integrating GPS positioning in conjunction with GPR and radio detection (LineTrac), users can locate and record underground utilities to obtain ASCE Quality Level B surveys and create network level SUE maps.

Data illustrates a computer screen shot of GPR data collected in a park with the UtilityScan system. Data was collected using the internal GPS system for positioning the GPR data. Screen image shows the data collection path and highlights the interconnection between RADAN 7 and Google Earth.
