Underflow drilling
Underflow
drilling is a new technique in witch drill cuttings are vented out
of the borehole by means of groundwater. Wells can be placed at
exact the right depth, by monitoring the cuttings. Samples can be
taken by various methods. Great advantage of this system is the
limited and controlled use of water and the low amount of displaced
ground. Wells can be plugged with bentoniet to prevent water or
pollutants from mixing with other layers.
Sampling on any location
For one of our clients, GWTR performed a unique
project for geotechnical research. With the aqualock-sample system,
samples have been taken through the rail-bed, till a depth of 10
meters.
All of this had to be done in between two platforms.
