Geotechnical Drilling
& Sampling Services
Your source for professional geotechnical drilling and investigation
Understand Your Soil Stability
We use geotechnical drilling to test soil stability before the construction of new buildings, parking lots, bridges, dams, and towers. We also use auger probes to determine the depth of bedrock.
Our experienced scientists and drill technicians pull from their vast knowledge of the area’s geology to strategically drill specific areas with our heavy-duty complex equipment.
You can count on HydroGeo to get you the information you need with minimal impact to your property.
The Proper Equipment Makes a Difference…
There are various types of geotechnical drilling, each requiring specific methods. HydroGeo maintains state-of-the-art equipment necessary for all types of geotechnical drilling, large jobs and small.
Our geotechnical drilling methods include:
Split-Spoon / SPT Sampler – This sampler is typically an 18” to 30” long, 2” diameter hollow tube, split in half, lengthwise. It is driven into the ground with a 140-pound hammer, falling 30”. The blow counts required to advance the sampler a total of 18” are counted and reported. This method is generally used for non-cohesive soils.
Shelby Tube Sampler – This sampler consists of a thin-walled tube with a cutting edge at the toe. Generally used in cohesive soils, this sampler is advanced into the soil and removed, with the retained soil collected for testing.
