Earthworks Quality Control

Experienced BGL staff are available to carry out quality control testing of earthworks and roading aggregates to ensure compliance with specifications. We will be happy to discuss your particular requirements & tailor a testing & reporting programme to suit.

Our parent company (Babbage Consultants Ltd.) is available to prepare a Foundation Completion Report at the end of works if desired. Testing carried out includes:

  • Nuclear Density Meter (NDM) testing of clay and aggregate fill to determine bulk (in situ) density, dry density, moisture content & air voids.
  • In situ density determinations using core-cutter/sampling tube method.
  • Dynamic Cone (Scala) Penetrometer & Impact Hammer (Clegg) testing to infer CBR values.
  • Laboratory Thermal Conductivity testing is also carried out.

Soil & Aggregate Sampling

  • From test pits, hand auger holes & machine boreholes.
  • Undisturbed block sampling.
  • Stockpile sampling.

Geotechnical Site Investigations

Experienced geologists & engineers are available to carry out a range of geotechnical site investigation work including:

  • Hand auger drilling to 5m with soil profiling, strength testing, sample recovery, & standpipe/piezometer installation.
  • Test pit & machine borehole investigations.
  • Slope stability investigations.

Geotechnical Monitoring

  • Inclinometer monitoring of slope movement – installation of inclinometer casing in boreholes, field monitoring surveys, & office production of displacement graphs.
  • Vibration & noise monitoring using an Instantel Minimate Plus seismograph & linear microphone.
  • Groundwater level monitoring using dip meters, pneumatic piezometers & downhole LevelLogger pressure transducers for continuous monitoring.

Environmental Investigations & Monitoring

  • Sampling of soil & groundwater for environmental analysis.
  • Installation of groundwater monitoring wells.

Non-standard testing can be undertaken by arrangement.
