Concrete Testing & Evaluations
CSR GeoSurveys Ltd. specializes in utilizing geophysical methods such as ground penetrating radar (GPR), ultrasonic tomography, and seismic (tomography and spectral analysis of surface waves (SASW)).
Information regarding concrete structures that can be determined utilizing geophysical techniques include:
• Identification and mapping of sub-slab voiding
• Reinforcement pattern and coverage
• Material integrity (P and S wave velocities)
• Flaw detection (voiding, spalling, open fractures, cold joints, honey combing etc.)
• Slab thickness/Pile depth
• Reinforcement oxidation
• Variation in material composition
Applications
- Damage prevention for concrete cutting and coring
- Bridge deck evaluation (milling, refurbishment, or assessment)
- Quality assurance and control (QA/QC)
- Engineering/Load bearing analysis
- Infastructure rehabilitation or repair
- Identification of impact caused by floods or water/sewer main breaks
