Rotary Drilling

Good architecture is like a good therapy session, a good marriage a good
poem gently and almost invisibly allowing you.

Rotary Drilling Services

Cable Percussion (or Shell and Auger) has been traditionally used in the site investigation industry for deeper boreholes in soft strata to determine parameters for pile designs and deep earthworks etc. The method can be inaccurate, dangerous and yield poor quality samples and test data.

We drill deeper boreholes using our new Massenza MI-2 rotary drilling rig. We are able to match Cable Percussion drilling rates and can drill up to 60m in soft or hard strata including bedrock!

We use a range of techniques depending on the depth, ground conditions, and sampling/testing requirements, including dynamic sampling with rotary follow-on, T2/T6 drilling for core recovery, wireline and Geobor S applications.

If you are purchasing one of our fixed-price packages or requesting a custom quote, we will decide on the relevant scope of testing necessary within the budget to meet the objectives of the report.

Alternatively, you can arrange specific laboratory tests if you know the individual tests you require.

  • Excellent sample recovery for reliable logging & testing
  • Variety of techniques suitable to all ground conditions
  • Options for dynamic probing, SPT tests & UT100/70 sampling
  • Can rotary core through competent strata such as rock​​​
  • The capability to concrete core through the surface ​​
  • Can use different casing diameters including clean drilling
  • Less operator errors compared to cable percussion
  • Accessible through gates & alleyways (rig width 780mm)
  • Tracking slopes up to 30 degrees​​
  • Excellent drilling productivity meaning quicker results​​
  • Using one rig for jobs requiring rotary follow-on
  • Soakage tests can be carried out
  • Borehole soakaways can be installed

Downsides of this technique are:

  • Not accessible up/down long runs of steps or stairs
  • Ventilation is required in enclosed spaces

Things to consider:

  • Headroom required is 3.60m
  • A water supply is normally needed
  • Deep boreholes can generate a lot of spoil & water run off
  • The rig is 2.65ft plus tooling and may damage surfaces
  • Reinstatement and safety requirements
  • A starter pit is usually hand-dug at surface to check for services (approx. 0.3m diameter)
