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.
