Core Sampling
Core extraction for laboratory compressive strength testing in a UKAS facility.
Concrete core sampling from Corvus is part of our concrete testing service. Core sampling extracts a cylinder of concrete for laboratory testing. We extract, log, and supply the core to a UKAS-accredited lab, returning the certificate as part of your report.
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 core sampling 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.
