Trenchless techniques

In urban areas or nature reserves, for example, it is not always possible or desirable to carry out traditional excavation work. That is why A.Hak uses innovative trenchless techniques, such as horizontal directional drilling (HDD) and the Direct Pipe technique. This allows cables and pipes to be installed or replaced without major disruption to the environment.

These trenchless techniques are sustainable, cost-saving and efficient. These techniques also make it possible to work under roads, railways or waterways. With our specialized teams and modern drilling equipment, A.Hak is a leader in this field and we realize high-quality solutions within the underground infrastructure.

An impressive example of A.Hak’s application of trenchless techniques is the project near Bergen op Zoom, where an 800-meter-long bore was made for a 150 kV high-voltage cable in collaboration with TenneT. This bore ran along two vulnerable Natura 2000 areas, making minimal impact on the environment crucial. What makes this project special is the use of Hydrogen Driven Drilling (H2DD): an innovative method in which the electric drilling rig is powered by hydrogen-powered generators.

The drilling was carried out completely emission-free. This sustainable approach has earned A.Hak the NSTT No-Dig Award from the expert jury, a recognition for innovative and socially relevant trenchless applications. Our trenchless projects show how A.Hak contributes to future-proof infrastructure with advanced techniques and environmentally conscious choices, even in ecologically sensitive areas.
