Concrete Core Testing
In-situ strength assessment of hardened concrete
About This Service
CTSL provides professional concrete core testing services to assess the strength and condition of hardened concrete. Using drilled core samples taken from existing structures, core testing provides valuable data to support structural assessments, compliance checks and quality investigations.
Our technicians carry out testing in accordance with BS EN 12504-1, ensuring dependable results to support structural evaluation and compliance requirements.
What Is Concrete Core Testing?
Concrete core testing involves extracting cylindrical core samples from hardened concrete for laboratory examination and compressive strength testing. This method is commonly used to assess in-situ concrete strength, investigate suspected defects or provide additional verification where further analysis is required. Core testing can support both new construction and existing structures.
When Is Core Testing Used?
- Verifying in-situ concrete strength
- Investigating low cube test results
- Assessing existing or ageing structures
- Quality assurance and compliance checks
- Structural investigations and defect analysis
- Supporting refurbishment or remedial works
Why Core Testing Matters
Core testing provides direct insight into the condition and performance of hardened concrete, helping clients validate structural integrity, support engineering decisions, investigate concerns with confidence, reduce uncertainty and demonstrate compliance where required.
