Pull testing on concrete

The Pull-Out System is an extraction test of a metal anchor for estimating the resistance of concrete on site. The extraction test called Pull-Out is classified between the semi-destructive methods of investigation.

The mechanical properties of concrete can be determined on site by measuring the force needed to pull a metal anchor pre or post inserted.
The test is performed using a manual hydraulic pump unit with a pressure gauge that drives a hydraulic jack connected to the anchor.

The value of the force produced by the test is used later to determine parameters of concrete strength by calibration curves and/or correlating the test with other methods of non-destructive investigation.
