It is fully capable of direct push probing with the GH64 percussion hammer, which now has two new significant features: a Modular Percussion Power Cell and integrated two-speed, bi-directional rotation. This is an industry first, and allows us to perform numerous rotational applications, including surface pavement coring and subsurface rock coring, with a rotation speed of up to 550 rpm.
The GA4000 augerhead allows for augering with solid and hollow stem augering to depths over 100', with the capabiltie of coring bedrock through the augers. We can perform NQ, HQ and PQ coring of bedrock to depths of 150'
