Characterization of the conservation state
            
        - Analysis and monitoring of vibrations in structures 
- Quality       and durability assessment for cement pavements
- Pull-out       test on bonded plates 
- Evaluation of the       integrity of concrete piles by sonic tests. 
- Termographic survey
- Measurement       of the superficial moisture in walls 
- Monitoring of the       evaluation of cracks and other structural movements
- Boroscopic inspection       of cavities and cracks
Apart  from these and other “in situ” techniques, Oz collects samples  for laboratory testing techniques, in particular the following most frequent  tests:
      
        - Petrographic       examination of concretes and mortars; 
- Control of the compressive strength of       the concrete one from cores.
