Gpr scanning concrete

There is inherent risk of striking rebar, electrical and communications conduits, and post tension cables during cutting, coring or drilling process. Ground penetrating radar ( GPR ) is regularly applied to examine concrete structures such as walls, floors, columns and bridges. It has recently gained popularity for concrete . The data is processed using specialist . Single line scan , Quickscan up to 30m, Up to ~ 350m.

Optimal depth of subsurface penetration is achieved in ice where the depth of penetration can achieve several thousand metres (to bedrock in Greenland) at low GPR frequencies.

Dry sandy soils or massive dry materials such as granite, limestone, and concrete tend to be resistive rather than conductive, and the depth of .

The cost of such mistakes can be prohibitive. GSSI provides the widest range of ground penetrating radar for concrete inspection, concrete imaging, roads, bridges, rails, rebar inspection and more. Radar Concrete Scanning is sometimes confused with Concrete X-Ray to locate post-tension cables and other objects in concrete construction prior to cutting or coring. At Global GPR Services we use Ground Penetrating Radar ( GPR ) equipment which uses radio waves that are safe and . At Penhall Technologies, a division of Penhall Company, we have specialized in concrete scanning for more than years. We employ expertly trained analysts that use state-of-the-art GPR ( Ground Penetrating Radar ) equipment to find common embedded objects and other subsurface hazards that are hidden in the . GPR concrete scanning 3-D images of post tension cables, conduit, pipe, wire, re -bar, voids, mesh, tubing, and concrete thickness.

Understanding the differences in GPR responses can help the engineer or technician distinguish between different targets of interest. In order to “ scan ” concrete with GPR , the instrument is placed flat on the surface. When the GPR is pushed along the concrete , still maintaining contact with the surface, it will . The Mala CX ground penetrating radar concrete scanning system is designed for the non-destructive investigation and imaging of concrete and other man-made structures.

We can provide both 2D and 3D images that are easy to interpret, allowing non-destructive testing to take place prior to any drilling, sawing or coring. Applications for Concrete Scanning . Subtronic has the equipment and experience to scan concrete with GPR to locate rebar, electrical conduits and post tension cables. This example illustrates real-time 2D scanning to identify embedde . Concrete scanning using GPR is more accurate, efficient and safer to use than radiography (x-ray). Though X-Ray and GPR ( Ground Penetrating Radar ) are used for similar concrete scanning applications, they are very different techniques.

X-Ray applies radiation to scan concrete and provides the on film. Our unit can scan large areas of concrete in one or more . D Concrete Scanning - LDM Scanning are at the forefront of 3D analysis of steel reinforcement in concrete structures.
