- Well abandonments
- Recovery of 3″ diameter by 10′ continuous cores
- Continuous sampling in saturated sands and gravel
- Telescopic drilling
- Geotechnical sampling
- Continuous Multichannel Tubing (CMT) well installation
- Landfill drilling
At Underground Sonic Drilling Services Inc. our focus is to reduce your project completion time, produce highly representative overburden and rock samples, and achieve your desired depths by utilizing versatile truck and track mounted sonic drills.

The Fastest Way to Sample
When sampling, our sonic drills operate at twice the rate of conventional drilling methods. In challenging formations such as heavy tills, heaving and flowing sands, coarse gravels, and cobbles, our sonic drills operate 4-5 times faster – minimizing project completion times.
In addition to the inherent speed and power unique to sonic drilling technology, our sonic drilling equipment has several integrated mechanical features to reduce manual labour and allow us to work more efficiently.
Highly Representative Samples
- Underground Sonic Drilling Services Inc. is a licensed Ministry of the Environment Well Contracting company utilizing superior Sonic equipment to provide you with:
- High quality, representative soil samples.
- Reduced project completions times.
- A safer work environment.
Sonic vibrations allow us to continuously dry sample overburden providing you with the most accurate identification of subsurface conditions for your test holes. These larger cores can easily be divided when duplicate samples are required.
By adjusting the frequency of these sonic vibrations we are able to quickly sample saturated sands without introducing drilling mud or polymers, which are commonly used in PQ soil coring.
Achieve Your Desired Depth
Our truck and track mounted sonic drills excel in all unconsolidated materials and bedrock. We mobilize to every job site equipped to drill in any geological formation that may be encountered – saving you time and money on equipment re-mobilization costs. We also arrive equipped to drill considerably deeper than the average environmental assessment offering you the ability to change the work plan when unexpected geological conditions are encountered.
Our sonic drills have the ability to core or displace through boulders, which would otherwise cause refusal with a conventional auger drill. One ten-foot core replaces the five SPT’s typically required.
