We can carry out testing to NZ and/or International Standards

Our tests include quality control testing, random verification testing (RVT), site sampling and testing, specialist advisory services, pore water pressure monitoring (vibrating wire piezometer), settlement monitoring (profilometer) and slip/lateral movement monitoring (inclinometer).

Routine tests are as shown below:

  • Basecourse/sub-base
    • Uniformity of material
    • Maximum dry density
    • Compaction control
    • Insitu density (Nuclear Density Meter (NDM) testing)
    • Water content
    • Clegg impact hammer
    • Benkelman beam

Subgrades/Cut to fill

  • Maximum dry density
  • Insitu density
  • Compaction control/air voids
  • Water content
  • Shear strength
  • Scala penetrometer
  • Benkelman beam
