Wall-mode Surveys
Purpose: Wall-mode surveys are specialized for imaging vertical surfaces, such as concrete wall faces, to locate and map internal structures. These surveys use Ground Penetrating Radar (GPR) and Radiodetection to detect features like rebar and other embedded elements, providing valuable data for structural assessments and construction planning.
Applications:
Structural Assessment: Wall-mode surveys are essential for detecting rebar, voids, and other minor features within concrete, helping engineers and contractors plan modifications or repairs without damaging the structure.
Detailed Mapping in Vertical Faces: This mode is ideal for situations requiring precise imaging of vertical surfaces where standard floor or ground surveys are not feasible.
Technical Process: Instruments like the Sensors & Software Conquest 100 GPR unit are used to penetrate up to 1 meter into concrete, identifying structural elements. By adjusting frequency, wall-mode surveys can balance depth penetration with resolution, allowing for flexible imaging based on project requirements.
Key Uses: Wall-mode surveys are critical in construction, engineering, and maintenance projects for assessing concrete integrity and identifying hidden structural elements, ensuring safe and effective modifications to built structures.
