Services
Subsurface Utility Locating
Our subsurface utility locating service identifies buried infrastructure using ground penetrating radar technology. We map gas, water, electric, and fiber optic lines to depths of 30 meters, providing accurate XYZ coordinates for safe excavation planning. This non-destructive method reduces project risks by preventing accidental utility strikes during construction activities.
Bridge Deck Inspections
Bridge deck inspections combine GPR and infrared thermography to evaluate concrete condition. We detect delamination, rebar corrosion, and structural weaknesses at highway speeds without lane closures. Our comprehensive reports include deterioration mapping and overlay thickness measurements to support maintenance planning for transportation agencies.
Concrete Imaging
Concrete imaging services visualize embedded elements in structural concrete. We map rebar, post-tension cables, and voids in slabs, walls, and columns. This non-invasive technique ensures safe core drilling and saw cutting operations while maintaining structural integrity during renovations or repairs.
Environmental Mapping
Environmental mapping services identify subsurface features for remediation projects. Our GPR systems detect bedrock depth, contaminant plumes, landfill boundaries, and abandoned mine shafts. This technology supports environmental assessments and land development projects requiring detailed subsurface information.
Pipeline Inspections
Pipeline inspection services locate leaks and structural defects in buried pipelines. Using multi-sensor technology, we identify problem areas in concrete, steel, and plastic piping systems. Our depth-accurate mapping supports maintenance planning for water, sewer, and industrial pipeline networks.

Questions
What subsurface features can GPR detect?
Our ground penetrating radar systems identify utilities, voids, rebar, bedrock, contaminant plumes, and structural defects to depths of 30 meters in most conditions.
How does GPR concrete scanning work?
GPR emits electromagnetic pulses that reflect from objects within concrete structures, creating detailed 3D maps of embedded elements without damaging the material.
Can you inspect bridge decks at highway speeds?
Yes, our high-speed data collection systems perform bridge deck assessments without lane closures using vehicle-mounted radar and infrared equipment.
Do you provide nationwide service?
We operate across North America with offices in Oregon, Nevada, Washington, California, and Alaska, supporting projects of any scale.
What data formats do you deliver?
We provide CAD/GIS files, 3D models, and comprehensive reports with georeferenced data for seamless integration into engineering workflows.
