Dual Tube Sampling

The Dual Tube (DT) 325 Soil Sampling System (from Geoprobe) uses a combination of cutting shoe, sheath, and liner retainer to allow efficient recovery of samples in formations ranging from plastic clays to saturated sands.

It is designed to quickly recover samples well below the water table and is ideal for continuous sampling.

The Dual Tube Sampler is also suitable for use in:

  • Installing 50mm standpipe
  • Providing casing support for our Piston Sampler
  • Installing pre-pack screen for Environmental Monitoring Well.

This service is currently available in our M2, M3, RFW and Marshbuggy CPT rigs.
