Your Source for Professional Geotechnical Drilling and Investigation.
When you’re choosing from geotechnical drilling companies, choose GES. Our team of experienced scientists and drill technicians have decades of experience in understanding the soil, water, and geology of the mid-Atlantic region. From the bedrock at the foothills of the Blue Ridge and Allegheny Mountains to the limestone of the Shenandoah Valley, our team uses their knowledge of local geology and state-of-the-art equipment to assay the physical properties of soil and rock at your site.
Geotechnical Drilling Helps You Understand Your Soil Stability.
GES is your source for all types of geotechnical drilling. 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 professionals 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 GES 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. GES maintains state-of-the-art equipment necessary for all types of geotechnical drilling, large jobs and small. GES 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.
Personal Service From Locals You Can Trust.
At GES, our team builds relationships with our clients based on quality services and professional project management. We are committed to providing a positive experience during your geotechnical drilling and use our knowledge of geology and mechanical backgrounds to ensure the data we provide is thorough, accurate and on time to keep your project moving.
