Our Common investigation methods...

  • Soil boring: Drilling into the ground to collect soil samples for laboratory testing.
  • Test pit excavation: Digging pits to visually inspect soil layers and collect samples.
  • Cone Penetration Test (CPT): Pushing a cone-shaped probe into the ground to measure soil resistance.
  • Standard Penetration Test (SPT): Driving a heavy weight into the ground to measure soil resistance.
  • Plate Load Test: Loading a plate on the ground surface to measure soil bearing capacity.
  • Inclinometer installation: Monitoring ground movement and deformation.
  • Stanpipe piezometers: Installation of wells to monitor, sample and assess the nature of groundwater.
