Laboratory Services

Our Construction Materials Testing Laboratories offer an extensive range of NATA accredited testing services covering earthworks, soil, aggregate, concrete, rock, asphalt, geomechanical and chemical testing.

Our laboratories are underpinned by our ISO/IEC 17025 accredited quality management system combined with a highly skilled and mobile workforce.

During construction, we understand the time and cost pressure affecting our Clients and provide the highest standards of service in terms of turn around times, quality and safety. We help our clients deal with the daily challenges of their projects, ensuring they remain on schedule and the construction meets project specifications.
