Gamma-Gamma Logging (GGL)

Construction Testing Services is certified by Caltrans for California Test Method 233 (CT233), Gamma-Gamma Logging.

Gamma-Gamma Logging (GGL) is a non-destructive test used for quality assurance of CIDH piles or concrete walls.

GGL is a type of engineering inspection used to determine the homogeneity of concrete in a pile.

The test requires a probe that contains a radioactive source to indirectly determine the concrete’s homogeneity and structural integrity.

This test is an essential part of many transportation projects that have bridges, like high speed trains and highways.
