| Geo-Tech has two truck mounted and one track mounted sonic rig to facilitate scheduling and mobilization from our Tualatin, Oregon office.
Sonic Drilling is taking off in the Northwest.
Sonic Drilling is the ideal drilling choice for
environmental sites with tough formations and
the need for highly representative samples and
little disturbance. Sonic drilling uses no drilling
fluids or air to move cuttings which minimizes
disturbance of the formation and helps to maintain
sample integrity. Our experienced crews are ready
to assist you on any of your projects.
To schedule or receive more information on Sonic
Drilling and its applications on environmental
and geotechnical projects please contact us (503)692-6400

What is Sonic Drilling?
Sonic drilling is a dual cased system that employs
the use of high frequency vibration to obtain
continuous core samples of any unconsolidated
formations and many consolidated formations (including
bedrock), and to advance casing for well construction
and other purposes. Sonic rigs can drill to depths
in excess of 300-feet and install test borings
and wells to angles of 75° off vertical. Well
installations are available from 1/2 inch to 8
inch diameter.
Because Sonic drilling does not use air, mud
or water like traditional drilling methods, it
is capable of collecting highly representative,
relatively undisturbed soil samples that can be
screened for VOCs. Depending on geotechnical or
environmental data needed, standard split spoons,
shelby tubes or any other conventional sampling
unit can be attached to collect a soil sample.
