Mapping Utilities in the Complex Built Environment

When mapping utilities in the complex built environment, it is important to have the proper tools and expertise. Subsurface Utility Engineering (SUE) is the process of mapping the utilities under your feet safely, before you dig. Complex distribution systems being utilized daily by millions can be hard to track, but geophysical tools like electromagnetic induction…

GPR Scanning of Concrete Pavements

Infrasense provides comprehensive GPR scanning of concrete pavements to map rebar and layer thickness of concrete and base layers. In addition to accurate rebar and pavement layer thickness measurements, the GPR data can be used to determine the precise location and alignment of each dowel bar and tie-bar. This information is invaluable for both rehabilitation…

GPR for Mapping Bedrock Topography and Revealing Subsurface Features

We employ advanced NDE methods, such as ground-penetrating radar (GPR), to map bedrock topography and reveal subsurface features – depth/elevation, areas of fracture or weathering profiles, or other potential weak zones – that can have a direct impact on infrastructure stability and performance. In addition to collected GPR data, borehole data can be used as…

GPR Survey to Map Bedrock in Northeastern MA

Infrasense engineers recently conducted a ground-penetrating radar (GPR) survey along a segment of road in northeastern Massachusetts in order to map bedrock topography. In this case, GPR proved to be an effective tool in mapping bedrock stratigraphy to approximately 25-feet maximum depth penetration. If you have an upcoming project where we can be of assistance,…

Subsurface Scanning of 1800s Cemetery

Infrasense recently completed subsurface scanning of an 1800s cemetery located in central Massachusetts. We used an array GPR system to identify the locations of graves (known and unknown). The multichannel Raptor system allowed for efficient data collection while producing a high-resolution 3D dataset of the subsurface! If you have an upcoming project where we can…

Tri-State Area Projects

Infrasense has completed multiple pavement and bridge testing projects in the Tri-State Area. These projects include ground penetrating radar (GPR) and falling weight deflectometer (FWD) testing of pavement sections; infrared thermography, video, and GPR scanning of bridge decks; and a suite of testing for evaluating bridge substructures. If you have an upcoming project where we…

Infrasense Completes GPR Surveys in Toronto

Infrasense is happy to announce that recently, we were able to travel back to Toronto to complete numerous ground penetrating radar (GPR) pavement thickness surveys. This included surveying over 2,600 kilometers of the City’s network! We are grateful to have worked as a subcontractor to ICC-IMS on this project. If you have an upcoming project…

Infrasense NRRA Research Project

The National Road Research Alliance (NRRA) has selected Infrasense for an exciting research project! This project objective comprises of automating 3DGPR data analysis for concrete pavement evaluations. The research includes developing machine learning algorithms to detect missing, misplaced, or misaligned dowel and tie bars, voids under joints, and other deficiencies in concrete pavements. If you’d…
