The Piston Tube Sampling technique developed by Probedrill is based around traditional Piston Type sampling methods, but with the speed and efficiency of a CPT Rig where suitable soil conditions are available.
A stainless steel tube (60mm dia x 500mm or 63mm x 500mm) is pushed to the target depth. The piston is retracted as the sample tube is advanced.
Piston tube samples have been tested up to depths of 20m.
Changes to our Piston Sampler means we now have a better seal and therefore have improved sample recovery, achieving 100% recovery from a tailings dam at just qt 0.4MPa.
Improvements have also been made to the locking mechanism to increase efficiency of operation.
This service is available with all our CPT Rigs.
