Trenchless Techniques

Drilling cables and pipelines: in today's congested surface and underground environments, it is crucial to have access to technologies that do not require excavation. Visser & Smit Hanab is a pioneer and leading expert in the field of trenchless technology.

Drilling techniques

What are the client's specifications? How long is the route? What is the pipe's diameter? What is the condition of the soil? What permits are needed? And what other environmental factors need to be considered? Clients generally have very specific reasons for choosing a particular drilling technique: development, route design, execution, management and maintenance considerations. We are at home in many different disciplines.


Directional drilling
Energy, water and communications: things we all take for granted. But their transport can be complicated, often involving a long ‘journey' past numerous obstacles, objects, waterways and vegetation. Trenchless techniques, such as computer-controlled directional drilling, make it possible to cross through existing infrastructure and natural resources. Horizontal directional drilling, shield tunnelling, guided auger boring and HDDW . With a wide range of technologies at its disposal, Visser & Smit Hanab can handle any drilling project.
