GPR Applications
Choose the investigation, then select the system
UTSI ground penetrating radar systems support service avoidance, utility mapping, road and railway assessment, concrete investigation, brownfield surveys and archaeological research.
Why Use GPR
Investigate what lies beneath the surface
GPR records reflections created by changes in electromagnetic properties, providing non-destructive information about buried objects, structures, interfaces and variations in ground conditions.
Reduce unnecessary intrusive work
Gather subsurface information before excavation, coring, drilling or destructive opening-up.
Investigate different target materials
GPR can respond to metallic and non-metallic objects, structural features, layers, voids and other material contrasts.
Collect continuous profiles
Survey data collected along a route or across a grid can reveal changes, patterns and areas requiring further investigation.
Configure around the investigation
Frequency, channel count, deployment method, positioning and processing should be selected around the required output.
Application Areas
Six routes into the UTSI product range
Each application page explains the investigation objective, suitable survey methods, relevant products and important limitations.
Construction and Excavation
Utility Detection & Mapping
Choose between simplified service avoidance, immediate mark-out and professional configurable utility-mapping workflows.
- Pre-excavation service avoidance
- Immediate on-site mark-out
- Metallic and non-metallic utility investigation
- Professional route mapping and interpretation
Highways and Pavements
Road & Pavement Investigation
Combine rapid asphalt spot measurements with configurable GPR profiling to investigate pavement layers and subsurface variation.
- Total bound-layer spot measurement
- Continuous pavement profiling
- Construction and layer variation
- Targeted coring and verification
Transport Infrastructure
Railway Investigation
Investigate ballast, sub-ballast, formation conditions and changes in trackbed construction using continuous radar profiles.
- Ballast and layer-interface investigation
- Trackbed construction variation
- Drainage and moisture-related change
- Deeper specialist investigation
Built Environment
Bridge & Concrete Investigation
Use high-frequency and configurable GPR to investigate reinforcement, concrete construction, interfaces and structural variation.
- Reinforcement and embedded-object mapping
- Slab thickness and interface investigation
- Support for drilling, cutting and coring
- Bridge-deck and approach profiling
Environmental and Geophysical
Environmental & Brownfield Surveys
Investigate buried structures, former foundations, made ground, fill variation and anomalous areas before intrusive work.
- Former foundations and buried construction
- Tanks, utilities and disturbed ground
- Made-ground and fill variation
- Larger-area and deeper investigation
Heritage and Research
Archaeological Investigation
Map buried walls, foundations, surfaces, ditches, pits, voids and changes in archaeological deposits without disturbing the site.
- Walls, foundations and buried structures
- Floors and former surfaces
- Ditches, pits and disturbed ground
- High-density grid surveys
Utility Workflows
Different levels of operation for different field tasks
The utility range separates straightforward avoidance, immediate mark-out and professional radar surveying instead of forcing every user into the same workflow.
e-Safe
Processed likelihood information for straightforward service avoidance without conventional radargram interpretation.
e-Spade Lite
Immediate Mark Out and Utility Mapping workflows with visible conventional GPR information.
GroundVue
Configurable channels, antenna frequencies and professional radar data for experienced survey operators.
Product Matching
Start with the required result
Final selection also depends on expected depth, target size, ground or structural conditions, survey speed, operator experience and required output.
Project Approach
Define the investigation before selecting the equipment
The most appropriate system depends on the target and required output, not only the general application category.
Define the target
Identify the expected material, size, depth, orientation and contrast with the surrounding ground or structure.
Assess the environment
Consider conductivity, moisture, surface condition, obstructions, access and the required survey speed.
Select the configuration
Choose frequency, channel count, deployment method, positioning and data-collection parameters.
Plan the output
Define whether the project requires rapid indication, mapping, interpreted information, archived data or formal reporting.
Specialist Applications
Some investigations require more than an off-the-shelf system
UTSI can assess requirements involving unusual target depths, frequency ranges, channel arrangements, mechanical deployment, data interfaces or research objectives.
