STRUCTURAL CONDITION ASSESSMENT 

Effective remediation of concrete structures is highly dependent on accurate diagnosis and characterisation of defects especially, depth / lateral extent of visibly external and hidden defects including: voiding, honey-combing, delamination, cracks, concrete inhomogeneities).

In accordance to industry standards methods and procedures (including AS/NZS: 2425:2015, ASTM D6432, ASTM D6431 – 99(2010), ASTM D6087 – 08(2015, we utilise multi-dimensional [2D/3D], [B-scan, C-Scan, D-Scan] high-resolution imaging techniques using high-frequency pulse radar (GPR) and Ultrasonic tomography technology to image through concrete and masonry.

Depending on the job requirements, specialised depth-slicing image processing techniques can be further applied to accurately locate, characterise and assess both depth and lateral extents of defects.

Benefits

  • Locate and Characterise Defects
    • Honey-combing and porosity in concrete
    • Delamination and internal cracks
    • Voids
    • Corrosion and deterioration of reinforcement
    • Sagging in reinforcement

 

  • Structural Geometry Verification
    • Thickness of slab
    • Reinforcement cover
    • Reinforcement type, spacing and diameter

Method

Depending on the specification, we conduct data acquisition, processing and reporting in accordance to: AS/NZS: 2425:2015, ASTM D6087 and ASTM D6432 standard procedures, for evaluating asphalt, concrete bridge structures.

Reporting is standardised, and results are presented in finely interpreted format for further engineering analysis.
