We can carry out testing to NZ and/or International Standards. Our tests include site subsurface and foundation testing for roads, bridges, buildings, airports, wharves and dams, landfills, subdivisions, greenfield sites, site sampling and testing and specialist testing services.

Laboratory testing includes:

  • Allophane detection
  • CBR
  • Core shrinkage
  • Linear shrinkage
  • Oedometer consolidation
  • Organic content (loss on ignition)
  • Particle size distribution
  • Permeability (falling and constant head)
  • Permeability of soils
  • PH value – electrometric
  • Plasticity index
  • Point load
  • Point load (rock core samples)
  • Repeated load triaxial
  • Resistivity of backfill
  • Automated triaxial compression tests
  • Tube density
  • Unconfined compression tests
