Tunnel horizontal directional coring: What is at stake ?

For any underground construction project, owners and contractors must have a precise and exhaustive geological profile. With this profile, engineers are able to identify the presence and localization of faults. This information enables project teams to identify and adapt proper methods and routes needed in order to operate a Tunnel boring machine (TBM).

How can VSL help you ?

Through a single hole, Horizontal Directional Coring (HDC) can provide more precise and relevant ground information data than tens of conventional boreholes.

In particular, it provides with ground information for the entire route of the linear structure.

In some situations where traditional holes are impossible to dig, HDC is the only alternative.
