Our soil testing estimates the characteristics of ground surface movement under the load of construction – a vital part of the process of creating a long lasting and safe built environment.

Characterising soils to determine the mix of sand, silt or clay facilitates a clearer understanding of the predicted behaviour of soils in a geotechnical design.

Our speciality soil testing measures strength and compressibility properties for the design of foundations, slopes and embankments – in accordance with New Zealand and Transport Authority standards.

We offer a range from common compaction control and quality conformance testing for the construction of roads and building foundations through to specialised geotechnical testing to determine  permeability characteristics of soils.

These specialised soil testing services include:

  • soil classification
  • material quality and conformance
  • compaction control testing including pre-treatment
  • routine stress and strain measurements
  • unconfined compression test
  • solid density tests
  • hydrometer/sedimentation particle-size analysis
  • chemical testing
