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…
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…
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…
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,…
Infrasense recently completed a project where we used GPR to assess settlement issues along a roadway in eastern Georgia. The areas showing evidence of settlement were in the vicinity of an underlying culvert. The GPR survey resulted in maps of subsurface voids and areas with evidence of moisture ingress possibly contributing to the settlement issue.…
Infrasense engineers recently completed GPR scanning of mechanically stabilized earth (MSE) wall systems in the Midwest. GPR data is collected along the fascia walls to measure the air void gap between the back of the fascia walls and surface of the MSE walls. Drilling is also carried out at select locations for direct measurements of…
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…
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 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…
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…
