Soil Investigation 

Simple Core Barrel

The simple core barrel is a very sturdy sampler, suitable for the sampling of soft formations

Double tube core barrel type T2

T2 series are thin core barrels for most types of homogeneous and rock formations where water flush can be used. The thin thickness means: -Faster penetration -Lower diamond bit consumption -Larger core diameter The reduced thicknesses guarantee:

  • High penetration speeds
  • Less consumption of diamond crowns
  • Carrots of larger diameter


Double tube core barrel type T6

The sturdy T6 core barrels are designed for core sampling in all formations. Despite the relatively thin thickness, T6 can also be used with mud or water. Thanks to this characteristic it can work indifferently with water and sludge.

Triple tube core barrel type T6

The sturdy T6 core barrels are designed for core sampling in all formations. Despite the relatively thin thickness, T6 can also be used with mud or water. Thanks to this characteristic it can work indifferently with water and sludge.
