Pull-Out Testing
Pull-out testing for in-situ concrete strength to BS EN 12504-3.
Pull out testing concrete from Corvus is part of our concrete testing service. Pull-out testing — Lok-test for new concrete, Capo-test for existing — gives you a calibrated in-situ strength estimate. We deliver the test, the calibration, and a defensible report you can put in front of a verifying engineer.
Built around the question being asked.
Test selection follows the question being asked. For in-situ strength estimation we combine rebound hammer with pull-out for a calibrated answer. For definitive results we extract cores and test them in a UKAS lab. We design the testing programme to give you defensible numbers, not just data points.
For pull-out testing specifically, the brief drives the choice of frequency, density, and reporting style. We quote a method that fits your access window, your accuracy requirement, and the downstream use of the data.
What you get
