Founded in 1992, we continue to grow a diverse team with expertise in engineering and testing.

• Starting salary of £26,000 per year
• Working hours 37.5 hours per week
• Pension scheme
• Regular training and CPD opportunities
• Flexible shift patterns
• Excellent entry‑level role for candidates with limited experience

We offer an opportunity for a Materials Technician Apprentice to support day‑to‑day laboratory and site operations. The role involves assisting with routine materials testing, maintaining equipment, and supporting technicians in the laboratory and on construction sites where permitted.

• Carry out basic laboratory tasks to support routine materials testing activities.
• Assist with making and demoulding of concrete cubes and beams.
• Maintain clean, organised, and well stocked laboratory and store areas.
• Clean, restock, and check testing equipment, ensuring calibration dates are current.
• Support vehicle management by updating tracking systems and confirming daily checks have been completed.
• Assist site teams when permitted and holding the appropriate CSCS card, including supporting coring operations and reinstating core holes.
• Log, trim, and prepare cores in the laboratory for compressive strength testing.
• Support on‑site concrete testing activities, including air entrainment, slump testing, and general quality control work.
• Weigh concrete samples in air and water to calculate density and assist with on‑site crushing tests.
• Assist with ground investigation testing, including plate loading, C  testing, and dynamic plate (LWD) testing.

This role is ideal for a candidate with limited experience, who will have the opportunity to develop as the role progresses.

You’re naturally curious about how materials behave and enjoy understanding why they perform the way they do, not just following instructions. You take pride in getting things right, paying close attention to detail, and producing accurate, reliable results. Whether you’ve explored science before or are just starting out, you’re motivated to build real knowledge and develop a long‑term career in a materials testing laboratory.

You thrive in a structured setting. You like clarity, routine, and knowing what good looks like. Following standardised test methods, working with laboratory equipment, and carefully preparing samples and recording data feels satisfying rather than restrictive. You’re patient, focused, and comfortable repeating precise tasks because you understand that consistency and accuracy are essential for high‑quality results.

You take safety, quality standards, and laboratory procedures seriously, and you approach your work with a calm, methodical mindset. You’re just as comfortable working independently as you are communicating clearly with colleagues, supervisors, and engineers. You’re motivated by analysing results, understanding why materials pass or fail, and progressing over time, building your skills step by step and becoming a trusted expert in materials testing.

This role does not require a full driving licence to apply, but you must be working towards obtaining one, as travel to various sites will be needed during the apprenticeship.
