CTSL provides a comprehensive range of concrete testing services across London and the South East. Our experienced technicians work around your programme to deliver fast, reliable results.
Concrete cube testing is the primary compliance test for concrete in the UK. CTSL collects or receives your concrete samples, cures them and crushes them to determine compressive strength in N/mm2. We test 100mm and 150mm cubes and provide results rapidly so your project stays on schedule.
- Sample collection or drop-off accepted
- Water curing
- Compressive strength result in N/mm2
- Written test report issued
Correct sampling is critical to valid test results. Our trained technicians visit your site to take concrete samples directly from the pour, cast and air cure them on-site and transport them to our laboratory. Serving construction sites across London and the South East.

- Sampling
- Proper mould filling and compaction
- Secure transport to CTSL laboratory
A slump test assesses the workability and consistency of fresh concrete before it is placed. CTSL carries out slump tests to current British and European Standards, providing a fast indicator of concrete uniformity and water content. Available across London and the South East.
- On-site testing
- Slump classification recorded
- Verbal and written result provided
- Fast turnaround on results
Core testing involves drilling cylindrical samples from existing concrete structures to assess in-situ compressive strength. This is used for post-construction compliance checks, investigation of failing concrete, or structural assessments. CTSL provides core drilling and lab testing across London and the South East.
- Core drilling on-site by CTSL technicians
- Laboratory compressive strength testing
- Full written report issued
- Structural compliance assessment included
