Scope of Accreditation

Lab Testing

Winstone Aggregates currently operates 5 independently accredited IANZ laboratories across the country from Auckland to Wellington. These labs employ approximately 50 staff made up of local and international technicians with extensive experience both in New Zealand and overseas.

Though testing aggregates is a core part of the business, some of Winstone Labs’ scope of accreditation included testing for typical field construction, soil, concrete and asphalt. This allows them to undertake major local, national and international infrastructure project testing. 

We provide safe, accurate and fast IANZ certified and accredited testing for the Civil Engineering and Construction Industry. Our labs perform soil, road, materials, project, site and lab testing from experienced lab technicians. 

 

Services include:

  • Nuclear Density testing
  • Dynamic cone penetrometer
  • Shear strength
  • Impact hammer
  • Sieve analysis
  • Plasticity index
  • NZ Standard / Heavy / Vibratory and Australian modified compactions
