Geo Sonic Drilling

We're all about good vibrations with the sample in the bag

The EP10 may be small but when it comes to the crunch that is what it does, on old land fill sites it can make itís way though most materials. Because of the use of high frequency vibration the sample is not as likely† to heat up which can be caused by other drilling techniques.

The Ep10 rig

Applicable to Indoor Operation . Mast height of 2.98m-2.63m and base machine width of 700mm and 900mm allows the drill to operate in many indoor situations.

Secure Stability of Drill. Rear blade will stabilise the drill while drilling takes place.

Lower peak noise levels than typical top hole hammers.

Low speed rotation combined with high frequency vibration lets the operator determine the optimum drilling method.

Mobility in Limited Space. By tilting the mast to 90 degrees, the height of the drill (1.84m) means that it can pass through the door of a house or building.

Quieter than a rotary percussion drilling rig.

Has the ability to retrieve highly representative, relatively undisturbed continuous core samples from both solid and unconsolidated materials.

No need for drilling fluid, allowing for uncontaminated core samples.

Dual tube method allows for simultaneous sampling and monitoring well completion.
