Concrete Testing & NDT
Strength, integrity, durability — measured properly, reported clearly.
NDT concrete testing from Corvus combines calibrated equipment, qualified surveyors, and engineering-grade reporting. On-site non-destructive and intrusive testing methods, including rebound hammer testing, pull-out testing, core extraction, and laboratory compressive strength testing.
Structural testing and sampling.
Concrete testing covers a family of methods used to assess strength, durability, and integrity in built concrete. We deliver non-destructive and intrusive testing methods, including rebound hammer testing, pull-out testing, core extraction, and laboratory compressive strength testing. Pull-out testing is semi-destructive and core extraction is intrusive.
Method matters.
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.
The right call at the right moment.
- 01
When concrete strength is in question
- 02
After a defect or distress is observed
- 03
Before structural alterations or change of use
- 04
When the original mix design is unknown
- 05
For dispute resolution and expert reporting
- 06
When commissioning new works requires verification
