Sonic sampling can give a very high quality sample in soft formations and uses high frequency vibration (50-180hz) which causes liquefaction of the material, up to 0.5mm-1mm around the drill string allowing it to pass quickly through any soft formation to great depths and retrieve exceptional samples, which can be pumped out into plastic bagging or a sample tray for sampling
The unit can be used on various bases and can be removed from its track base and placed on the boom of a loadall machine with the power pack in a trailer or can be craned onto a pontoon to work over water sample quality in very soft strata is where the unit really excels
Our machine also has a planetary gearbox that can be mounted on the rig to give it rotary capabilities instead of Sonic

Safety:
Fully Interlocking guard.
Achievable Depth’s
Drilling depth’s for this machine vary depending on Geology but we have used it to sample sediments to 20m.
The rig stats for access:

  • Weight = 8 tons
  • Width = 2.3m
  • Access Height = 2.3m
  • Working Height= 3.8 m

Drilling Methods Available
Sonic Drilling

  • The unit can sample sands/gravels/alluvium/soft clays and chalk up to and over 30m

Installations
Once drilling is complete in a size and method agreed the created bore can simply be backfilled or installed with a vast array of ground monitoring instruments as required.
Solid/Hollow Stem Auger
Auger to depths of 10m dependant on geology.
