We perform many subsurface explorations in-house using both our AMS 9500 VTR PowerProbe™ and our AMS 9630 truck PowerProbe™. 

Our geotechnical exploration capabilities include:
  • Seismic Cone Penetration Testing (SCPTu)
  • Conventional Auger Boring with SPT Sampling 
  • Direct Push Percussion Casing with Push Tube, Shelby Tube, and SPT Sampling
  • Groundwater Monitoring Wells
  • Test Pits

Our environmental drilling capabilities include:
  • Cone Penetration Testing (CPTu)
  • Hollow Stem Auger Boring for Soil Exploration
  • Direct Push for Soil Sampling (Soil Liners)
  • Groundwater Monitoring Wells 
  • Direct Push Groundwater Monitoring Wells 
The AMS 9500 VTR PowerProbe™ is a remote controlled rubber track ATV direct push/auger exploration machine capable of remote site access with low ground pressure.

The AMS 9630 truck PowerProbe™ is a larger machine mounted on a Ram 5500 4x4 truck.  Both are capable of conducting seismic cone penetration testing (SCPTu) using Vertek instrumentation.
 
The Vertek VTK cone system includes a real-time data logging system with 5 ton and 10 ton SCPTu cones.  SCPTu cones are equipped with tri-axial seismic modules to provide both S and P shear wave velocity testing.  SCPTu is performed with a single or dual point anchor system pushed at a controlled speed of 2 cm/s with adjustable hydraulics and monitoring instrumentation capable of applying up to 17 tons of push force.  

This compact yet powerful combination provides high quality geotechnical and environmental explorations for continuous subsurface profiling and data collection.
