From our head office in Dorset on the south coast of England, we have provided independent professional materials testing and consultancy services to the building, waste, quarrying, construction and civil engineering industries since 1987. Over the past 30 years, ACS has steadily expanded and developed, now providing a comprehensive UKAS accredited sampling, site testing and laboratory testing service for a wide range of materials, the results of which ACS can translate into interpretive reports to meet our Client’s needs. Our team’s decades of expertise are entirely portable and can be relocated as required, including in our satellite laboratories in Bristol and Horsham, and in bespoke site laboratories.

ACS will always endeavour to help you achieve your objectives with our seamless all-in-one service, which includes;

Training is carried out in accordance with our Laboratory Quality Manual and assessed by UKAS as part of the ISO / IEC 17025 : 2017 accreditation. ISO / IEC 17025 : 2017 is specific to laboratory accreditation, incorporating and exceeding the requirements of ISO 9001.

All ACS staff who work on sites hold a CSCS Card, and therefore must have passed the relevant CITB Health, Safety & Environment (HSE) Test for their job role. In addition, activity specific HSE training is provided and updated frequently.

Every person employed by ACS will receive training to enhance their value to both the company, themselves and society. Many of our staff have worked for ACS for more than twenty years and so have a vast experience and understanding of materials management and how properties influence the way materials can be used. Our Managing Director has worked in the groundworks civil engineering sector for more than forty years, and our staff include graduate chemists and geoscientists, who are active members of their chosen professional body and engage in continuous professional development, either working towards or already chartered.
