Main information

DualWall CoreBarrel benefits
- Improve sample quality and recovery in harder and mixed formations
- Do not flush away the fine material in a sample
- Do not miss any layer!
- A monitoring well can be installed directly after sampling through the casing
- No deviation in formations with boulders and hard layers
- Very accurate sample of overburden intersection going over into hard bedrock
The DualWall core barrel sampler is designed to take high-quality samples in formations that are normally a nightmare. It will work best in formations that contain harder layers or boulders. It can even handle very soft alluvial formations going over into a hard material. The sampler has an annular space in the barrel that makes it possible to use a medium without washing away the fine material. For ring bit selection there is a front or side discharge available. The front discharge is used in homogeneous hard formations. The side discharge version is designed for mixed formations, it will prevent that fine material is flushed away. A casing makes sure that the borehole does not collapse when emptying the sampler. The DualWall Core barrel is available in 3 different diameters to match your requirements. Cores will be sampled straight in the core barrel. The sample can be extruded into polyethylene foil tube, plastic gutters or core box.
