Crack Detection

Crack detection in concrete can be easily performed by using water for contrast enhancement The surfaces to be investigated can either be watered from the surface or from the back In the latter instance water appears at the surface by capillary moisture transport through the crack As water has a higher emissivity than concrete the crack
