Principle

The objectives of the Ultra Sonic Pile Integrity Testing (RSM-SY7) are to determine the homogeneity and integrity of concrete between the probes. The data are used to /confirm/i adequate concrete quality or identify zones of poor quality (due to inadequate vibration, segregation due to over vibration and/or improper concrete placement, washouts of cement due to groundwater flow, cracks due to shrinkage, contamination of the concrete, etc). If defects are detected, then further investigations should be made by excavation or coring the concrete as appropriate, or by other

testing methods.

Features
