We have an experienced team who have been part of the aggregates and concrete sector for decades. We’re committed to innovation and the industry, and we work to support the aggregates sector. We represent Stevenson on a range of organisations including the Aggregate and Quarry Association (AQA) and various transport infrastructure committees.
Our expertise is backed by over 40 years of proven industry experience. In 1975, we obtained IANZ accreditation (formally known as TELARC), and became one of the first non-Government owned certified civil engineering testing laboratories in New Zealand.
IANZ accreditation is formal recognition that our laboratory and its staff have been independently assessed and are deemed capable of performing tests to the requirements of national and international standards for which it is registered. For a copy of our IANZ Scope of Accreditation click here.
