Sonic drilling

DSC01541.JPG

Sonic drilling is a technique making use of intense vibrations directed down the drill string causing liquefaction of the soil at the cutter shoe, enabling extremely rapid soil penetration with relatively light drilling equipment. The system benefits from little or no drill spoil and does not require air or water flush to advance the drill string.

We offer two Sonic Wizard tracked drill rigs which provide the highest quality of environmental soil sample. All our rigs use biodegradable hydraulic oil.

Suited to soft to firm and loose to medium dense ground conditions. Not suitable for dense sands, gravels, hard rock or concrete conditions. Depth range down to 20m depending on ground conditions.

The GP100 rods can be used to install up to 50mm monitoring wells when combined with the lost point system in unconsolidated ground conditions. The Aqualock takes very high quality discrete samples in the same conditions such as sands or fine gravel.
