At CMTL we provide comprehensive aggregate testing to meet British and European standards. Our mechanical and physical tests are suitable for a wide range of natural and recycled aggregates, ensuring they are fit for purpose.

Aggregates used in construction projects must meet strict regulation and quality standards. Complying with these standards is often compulsory, so using our independent UKAS* and INAB accredited laboratories for testing guarantees your compliance.

Benefits of Aggregate Testing

  • Comply with the relevant British and European regulations and quality standards
  • Enable informed decisions on aggregate use from test results
  • Ensure the quality of aggregate for its intended purpose
  • Evaluate the performance of available materials
