Ground Penetrating Radar
Reliable diagnostics for concrete structures and other materials.

Structure Scan
Concrete scanning with ground penetrating radar is a well-defined application. Unlike X-rays techniques, there are no issues with unsafe radiation. Concrete scanning with a high frequency antenna can locate many targets within concrete. For example, post tension cables, buried pipe or conduit, wires, reinforcing bars, and voids. With optimal site conditions, one may be able to image a trench, drainpipe, waste pipe, or vent pipe beneath the concrete slab. New concrete, precast concrete with void spaces, and concrete with metal fibers or metal screening often yield undesirable results. When looking concrete scanning services, know that we offer the best value and the best equipment and analytics.

Pavement Thickness Analysis
Working for DOT or an independent Engineering company this application would provide joint valuable information system for their data bank or project planning. The method is similar like the other GPR technics except the antenna emits out signal from the air therefore this method is called Air Launched GPR. Data acquisition is fast, the surveying vehicle can move up to 60mph on a Highways or Roadways. The report is always presented in a common GIS form.

Subsurface Condition Assessments - Void Investigations
Ground Penetrating Radar also know as GPR is suitable to perform ground condition assessments with. Lower frequency unit is capable to emit EM signal that can propagate through 3-10 feet thick soil. The signal penetration is always depending on other factors and parameters such as material permittivity, density, and moisture content. The signal penetration is in reverse proportional with antenna frequency. A properly design 3D subsurface GPR scanning could provide appropriate information about near field anomalies up to 10 feet. By combining the digital/analog GPR data set with GPS positioning information a comprehensive GIS (Geographic Information System) map will be created that provides valuable information about the ground conditions qualitatively.
Subsurface condition assessment service is generally provided to Oil and Gas Industry and Chemical Plants to provide them quality and safety assurance in a highest level. Working close together with area owners, plant engineers or Craning & Rigging department void survey is always recommended prior to heavy machinery placement or before any rigging, hoisting is taken place inside a facility. The provided map will be showing hot spots where ground quality is different, and the detected anomalies are showing some kind of abnormality in the soil underneath the area where a heavy crane will be erected or placed. This information will be translated to the competent person in order to make further action to mitigate the unknown danger(s).
