Defects and Damage
What is GRP delamination and how is it detected?
Delamination is the separation of laminate layers and it reduces hull strength directly, usually without any sign on the surface. The one practical detection method is sound: a sounding hammer returns a dull note over a void.
Why it works this way
Suspect areas are then confirmed with moisture readings and, where needed, ultrasonic measurement. It is the clearest example of a defect that a visual inspection simply cannot find.
