Ground Penetrating Radar Data Experts

GPR Data Inc. is a leader in non-destructive, non-invasive, cutting edge, geophysical testing and sub-surface investigations. Our licensed professional staff provide superior services and comprehensive engineered solutions to clients around the world using state of the art ground penetrating radar technologies to image the earth and concrete.

GPR Data Inc. technologies produce accurate information pertaining to cracks, delaminations, voids, honeycombing, and debonding in plain, reinforced, and post-tensioned concrete structures, including plates (slabs, pavements, walls, decks), layered plates (including concrete with asphalt overlays), columns and beams (round, square, rectangular and many I and T cross-section members), and hollow cylinders (pipes, tunnels, mine shaft liners, tanks). Our methodologies can be used to locate voids in the grouted tendon ducts of many types of post-tensioned structures. We can provide thickness measurements of concrete slabs with an accuracy better than three percent, and can locate voids in the subgrade directly beneath slabs and pavements. Our methods can be used to determine thickness or to locate cracks, voids, and other defects in masonry structures where the brick or block units are bonded together with mortar.

Unparalleled experience, state of the art equipment, and expert staff allow us to provide precise high resolution subsurface information to depths reaching 30 meters.

Why is GPR Data Inc. the experts in ground penetrating radar?

Our clients and the complex challenges they present to us have made GPR Data Inc. the industry experts in ground penetrating radar technology. GPR Data Inc. has the professional experience to deliver the critical information our clients need. This experience is illustrated by our ability to collect, process, interpret, and display accurate GPR data obtained from any work site in the world. GPR Data Inc. strives to provide highly accurate comprehensive data by utilizing our in house 3D digital processing.

GPR Data Inc. employs the following non destructive testing technologies:

Full Resolution Ground Penetrating Microwave Radar (GPMR)

Full resolution ground penetrating microwave radar (GPMR) imaging is a technique pioneered by GPR Data Inc. Our techniques prevent aliasing during post processing and yield contiguous subsurface information in every direction. This in house data collection and 3D processing technique images at dense interval resolution resulting in crisp clear high definition 3D data.

Impact Echo (IE)

Impact echo (IE) testing is a proven method for nondestructive evaluations of reinforced concrete and masonry structures that is based on the use of impact-generated stress (sound) waves that propagate through concrete and masonry and are reflected back by internal flaws and external surfaces. Impact-echo can be used to determine the location and extent of flaws.

Infrared Thermography (IR)

Infrared thermography (IR) is a technique using high definition thermal imaging cameras to produces images of infrared radiation levels omitted by different objects or materials. With this technology we can map these infrared radiation levels to produce images or thermograms. All objects with temperatures above absolute zero omit certain levels of infrared radiation – as an object’s temperature increases so does its infrared radiation signature. Thermography allows us to see into our customer’s environment with or without visual illumination.

Sub Decimeter Global Positioning (GPS)

Sub decimeter global positioning (GPS) allows us to reference our data to centimeter accuracy from any work site in the world. Our GPS systems work on GNSS satellite technology and are fully integrated with each of our geophysical technologies to produce accurate positioning reference data deliverables.
