CTS and our range of independent UKAS accredited laboratories provide on-site testing and laboratory services to the construction, quarry products and civil engineering industries across the whole of the UK.

Our purpose-built laboratories are fully equipped to test the mechanical, physical and chemical properties of soils, aggregates, concrete and bituminous materials as well as other construction materials and products. 

Our highly-trained technicians and engineers either visit sites and take representative samples for subsequent laboratory testing, or conduct in-situ field tests. 

As aSenior Materials Testing Laboratory Technician, you will be responsible for performing a wide range of materials testing on soils, aggregates, concrete, and other construction materials. You will also provide technical support to junior technicians, help manage the day-to-day operations of the lab, and ensure that testing procedures are carried out accurately, safely, and in compliance with industry standards.

Key Responsibilities:

• Conduct a variety of materials tests, including but not limited to compaction, grading, moisture content, and strength testing on soils, aggregates, and concrete, following the relevant standards (e.g., BS, EN, ASTM).
• Assist in the preparation and analysis of test samples, ensuring all materials are handled and stored appropriately.
• Provide technical guidance and support to junior technicians, assisting with their training and development.
• Ensure that laboratory equipment is properly maintained, calibrated, and ready for use.
• Interpret test results, prepare reports, and present findings to senior management or clients as required.
• Monitor and uphold laboratory safety standards, ensuring compliance with health and safety regulations.
• Manage the recording, storage, and archiving of test data and results, ensuring they are accurate and easily accessible for future reference.
• Assist in the management of laboratory supplies and equipment, ensuring adequate stock levels and timely ordering of consumables.

• Proven experience (2+ years) in a materials testing laboratory, with a strong knowledge of testing methods for soils, aggregates, concrete, and related materials.
• Familiarity with testing standards (e.g., BS EN, ASTM, ISO) and the ability to carry out tests in compliance with these standards.
• Good understanding of laboratory equipment and the ability to troubleshoot basic issues.
• Strong attention to detail, ensuring accuracy in test results and reporting.
• Excellent organisational skills, with the ability to manage multiple tasks and prioritise effectively.
• A proactive approach to safety and a thorough understanding of health and safety protocols in the laboratory environment.
• Good communication skills, both verbal and written, with the ability to prepare clear and concise test reports.
• Ability to work independently and as part of a team, providing leadership and support to less experienced technicians.

Desirable Attributes:

• Experience with laboratory accreditation processes, such as ISO 17025.
