25 Years of Expertise

in Extracting Quality Data

Utilizing Advanced CPT Equipment to Deliver Precise Soil and Groundwater Data

Providing Geotechnical and Environmental Engineering Services Across the West Coast

With over 25 years of experience operating CPT equipment for geotechnical, environmental, and scientific clients across the West Coast, we can provide the highest quality soil and groundwater data tailored to your needs.

From small residential additions to multi-million-dollar foundations and expansive solar farms, we can adapt to your project’s requirements. We can characterize sediment up to 150ft deep in a matter of hours while logging pore pressure and taking discrete seismic profiles of your site. Utilizing direct-push hydraulics, we have the capacity to quickly log 8–10 locations in a day and push far deeper than traditional drilling rigs in the same amount of time. If needed, discrete soil and groundwater samples can be collected at any depth.

Compared to traditional drilling, CPT offers much higher productivity (300' to 400' per day) at significantly lower cost, waste, and noise levels. Data can be processed immediately and sent from the field, further reducing costs.

“I am pleased to see that Bobby Hancock is now his own. Bobby has been my first choice as a operator and vendor for CPT for well over a decade. His dedication, conscientious attention to detail and operation has given me the confidence to rely on CPT data he obtains for geotechnical analyses and design. I have found the CPT data he obtains both credible and reliable. Bobby also has the insight to design and implement special exploratory techniques with success such as deep CPT soundings and seismic cone testing to depths of 150 feet within boreholes.”

"I have worked with Middle Earth Geo Testing Inc. on dozens of projects over the past almost 10 years and I don’t think I have ever had any problem with their service. Only one time they experienced some issues with the rig and Bobby worked over the weekend to finish the job. I always get reliable data on time, and the invoicing is simple and honest. I would continue to use their services and would highly recommend it to fellow engineers."

"Middle Earth Geo Testing is among our preferred and trusted CPT and in-situ testing providers. They are responsive, nimble, flexible, and provide high quality in-situ testing data in a timely fashion. Because of their excellent service and reasonable rates, they are often booked weeks in advance. However, they frequently accommodate time-critical projects by filling cancellation spots and strategic scheduling. Geocon owes a lot of our success to our trusted service providers. Middle Earth Geo Testing is truly a trusted partner and we highly recommend them to anyone in our industry."

"GSI (GeoSoils, Inc.) of Southern California uses Middle Earth Geotesting, Inc. because of our commitment to our clients for the best combination of quality and price available for cone penetration testing. As costs begin to climb and the competition is tightening in this economic market, Middle Earth keeps our small business competitive. Other firms cost 50 to 75 percent or more for the same field service. The personal attention to the data interpretation and data reduction as well as a variety of field options is why GSI will look to Middle Earth in the future for our field evaluation needs."
