Through extensive in-house capabilities and strategic relationships, Alpine can provide its clients with a full range of geotechnical capabilities worldwide. 

Through Alpine, clients can access the following geotechnical sampling services:

  • Van Veen, Day Grab and Shipek Samplers
  • Drop and Piston Cores
  • Vibracores (Electric and Pneumatic) capable of up to 40 foot penetration. Most systems come equipped with Jetting and CoreLog capability.
  • Seafloor Deployed CPT Units
  • Marine Drilling Systems with Downhole CPT capability

All of our geotechnical staff are OSHA 40 Hour HazMat certified and trained in proper sample handling and preparation for lab analysis. 

Alpine is the Leader in Vibracore Manufacturing and Sampling

Alpine has over 50 years of experience as a leader in the manufacturing and use of Pneumatic and Electric Vibracore sediment sampling equipment. Alpine developed and produced the first pneumatic Vibracore as part of the US Army Corps of Engineers’ Coastal Engineering Research Center 1964 Sand Inventory Program. Our systems now represent the gold standard for the industry.

Alpine can supply a variety of vibracore systems making it easy to find the ideal solution to a client’s sampling requirements:


Full Size Systems capable of obtaining samples up to 40 feet long

Mini System capable of obtaining samples up to 12 feet long


Rated to 1000 feet water depth, these units are capable of securing samples up to 40 feet long.

Most Alpine Vibracores (electric and pneumatic) can also be outfitted with our proprietary Corelog© System and/or a high pressure Jetting System:

  • Corelog is a proprietary logging and processing system capable of recording, in real time, a variety of important data on the Vibracore’s progress through sediment. The data can then be immediately processed into graphical format for review or stored for later analysis.  Output from the system includes US Army Corps standard penetration graphs.
  • The Jetting System uses high pressure water to greatly increase the chances of achieving target sample recovery in most sediments when conducting multiple runs.
