Cone Penetration Testing Services

Now offering CPT services

Pitcher is now offering CPT services with the support and training of our sister company, Gregg Drilling. Gregg Drilling has been a leading provider of CPT services in the Western US since the early 90’s. Pitcher now operates one of Gregg’s custom designed 30-ton CPT trucks out of our Palo Alto location. Our CPT services include standard cone penetration testing and seismic CPT along with various direct-push and discrete soil samplers.

Safety is our priority

It is our company policy to hand clear locations to 5ft for utilities and we stand by our commitment to this practice. Not only does it enhance the safety of our crews and clients on-site, but the general public and environment as well. Other service providers may skip this critical step to increase their daily production but we are invested in the people and planet and will not sacrifice safety for the bottom line.


Technical Expertise:

Pitcher relies on the highly trained data quality monitoring provided by our sister company, Gregg Drilling. Our CPT data is reviewed by Gregg’s reporting team and processed using industry standard software, CPeT-IT and provided to our clients in PDF, data files and a CPeT-IT project file.
