Infrasense has performed vehicle-based infrared thermography scanning of thousands of bridge decks throughout the country. Vehicle-based IR is faster, safer, and more cost-effective than traditional bridge deck inspection methods. It allows for high-precision data collection with no lane closures, no personnel exposed to traffic, and the capability of scanning dozens of decks per day. We…
DetailsCondition assessments for parking structures involve the use of multiple NDT tools, like ground penetrating radar (GPR), impact echo (IE) and rapid automated sounding (RAS). GPR is an effective tool for detecting issues within concrete components such as parking decks, ramps, beams, and columns. Such issues can include moisture intrusion, concrete deterioration, cover thickness and…
DetailsMany bridges in the U.S. are nearing the end of, or already exceeding, their design life. Due to this, agencies are increasingly looking for efficient ways to evaluate the condition and structural integrity of bridge substructure elements. To meet this demand, a comprehensive evaluation may be completed. This evaluation uses a suite of methods including…
DetailsWhen 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…
DetailsInfrasense 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…
DetailsWe 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…
DetailsLeveraging cutting-edge NDE methods, the Infrasense Southeast Office has been hard at work on numerous advanced pavement evaluations. These include work on critical roadways throughout Tennessee, Georgia, Virginia, South Carolina, and Florida. Our team detects pavement layer thicknesses, stripping in asphalt pavements, voiding in the base/subgrade, structural capacity of the pavement structure, and much more.…
DetailsInfrasense leverages advanced Aerial IR and visual imaging to map bridge deck delaminations, patching, and spalling. Using high-sensitivity thermal cameras, we can pinpoint areas of deterioration invisible to the naked eye. Our nondestructive approach allows for rapid, large-scale assessments that prioritize efficiency, safety, and affordability while minimizing traffic exposure or disruptions. If you have upcoming…
DetailsRapid Automated Sounding for Bridge Deck Condition One of the newest nondestructive testing technologies in use at Infrasense is our Rapid Automated Sounding (RAS) system. This system elevates the traditional method of detecting bridge deck delaminations by combining automated chain strikes, microphone arrays, and algorithmic audio analysis – delivering impressive accuracy and efficiency. RAS collects…
DetailsAt Infrasense, we understand the importance of precision and safety in completing infrastructure projects, which is why we often utilize 3D Ground Penetrating Radar (3DGPR) for utility and obstruction mapping. 3DGPR surveys let us provide detailed imaging of subsurface utilities and obstructions without the need for lane closures. The 3DGPR data is combined with as-built…
