Non Destructive Testing by Acoustic Emission & Ultrasonics : Diagnosis of Civil Structures

Our knowledge at your disposal

For the inspection and continuous monitoring of civil structures,
by Acoustic Emission, Impact Echo, Ultrasonics...

Acoustic Emission is a non intrusive method for a global diagnosis of the structure's health. Tests are performed in laboratories, in the field and on in service structures. Some examples of our knowledge in Civil Structures :

In service monitoring of civil infrastructures

Internet based on line monitoring
    of suspension cable bridge

Test after repair
(steel bridge)

Geotechnical Applications

Prediction of slope failure

Damage evaluation of concrete
wall built to prevent landslides

Process Control

Compaction process
    monitoring of concrete

Acousto-Ultrasons used for
roller compacted concrete
