Non Destructive Testing
At Streval Ltd. we excel in the area of non destructive testing. We can carry out the following NDT investigations:
- Ground penetrating radar for stratification, buried objects, utility location, concrete investigation, water saturation and concrete condition.
- Ultrasonic Pulse velocity.
- Schmidt Rebound Hardness.
- Ultrasonic Pulse Echo for concrete voiding, concrete thickness, and honeycombing.
- Impact response (s’MASH) for uniformity assessment of plate like structures.
- Impact echo for slab thickness.
- Ultrasonic metal thickness measurement.
- Back scattered electromagnetic response (BSEF) analysis of GPR data for water saturation and voiding.
- Electromagnetic location of utilities.
- 4 probe concrete resistivity to understand porosity.
- Rebound metal hardness.
- Half-cell corrosion rate measurement.
- Screed drop hammer test for screed hardness.
