Laboratory and Field Testing
Winstone Aggregates currently operates 4 independently accredited IANZ laboratories across the country from Auckland to Wellington. These labs employ approximately 30 technical staff with extensive experience both in New Zealand and overseas.
Though testing aggregates is a core part of our business, Winstone Aggregates Labs’ scope of accreditation includes laboratory and field testing for typical construction, soil, concrete and asphalt.
This allows us to undertake major local, national and international infrastructure, earthworks and geotechnical project testing.
We provide safe, accurate and fast IANZ certified and accredited testing for the Civil Engineering, Geotechnical and Construction Industries.
Our labs perform soil, roading, material, project, site and laboratory testing, undertaken by experienced lab technicians.
