We perform aggregate testing to help you choose products for your construction projects. We assess options and identify the ones that comply with New Zealand standards and ASTM to produce the best possible project outcome.

We’re focused on providing timely and high quality information through the use of  Qestlab LIMS System and continual sample response tracking to applied shear pressures.

Our aggregate testing delivers enhanced integrity and reliability of results from an increased area of the shear plane. It provides size, shape and density analysis as well as strength and durability testing to ensure compliance of aggregates in:

  • granular base and sub base materials for surfaced road pavements
  • selected material in formation
  • storm water drainage
  • size, shape and density analysis
  • strength and durability testing
