22 kilometers of cable protection tubes for 15 km of directional drilling (Elia project)

Deschacht provides crucial link for future electricity grid

The energy transition requires a stronger and future-proof infrastructure. A great example of this is the extensive Elia project between Zottegem and Aalst, where a new underground high-voltage connection is being realized. For the execution of the horizontal directional drilling, contractor BESIX UNITEC is relying on Deschacht's expertise for the supply of no less than 22 kilometers of cable protection conduits.

The project is part of the renewal and reinforcement of the electricity grid between Zottegem and Aalst. The existing overhead high-voltage line is being replaced by a new underground connection that is ready for the future energy needs of the region.

Impressive scale

With a total of 22 kilometers of cable protection conduits, this project ranks among the larger HDD (Horizontal Directional Drilling) applications in Flanders. The drilling operations are carried out by BESIX UNITEC, under the management of project manager Edis Karadan.

Thanks to horizontal directional drilling, long routes can be realized with a minimal impact on the environment, infrastructure, and mobility. This technique offers an efficient solution for the installation of utility lines in locations where traditional open trenches are less suitable.

Quality as a starting point

For this project, BESIX UNITEC deliberately chose PE100 Virgin pipes. These pipes are produced without recyclate, ensuring a consistent and high-quality standard. Their properties are comparable to those of a BENOR-approved pipe, which provides an important guarantee for a project with such a lifespan and strategic importance.

Deschacht was not only responsible for supplying the pipes, but also handled the logistical organization and unloading at the construction site. Smooth availability of the materials was essential to support the tight execution schedule of the drilling operations.

Trust as a basis for cooperation

Besides the technical specifications, the years of collaboration between Deschacht and BESIX UNITEC also played an important role in the realization of this project. The good relationship between account manager Jeroen Walgraeve of Deschacht and the BESIX UNITEC team formed part of the basis for a successful collaboration.

A competitive price, combined with technical support, delivery reliability, and mutual trust, was the deciding factor in choosing Deschacht as a partner within this prestigious infrastructure project.

Building the energy grid of tomorrow

With the delivery of 22 kilometers of cable protection conduits, Deschacht is directly contributing to a project aimed at increasing the reliability and capacity of the Belgian electricity grid. The new underground connection will eventually be able to transport more electricity than the existing overhead line and represents a major investment in the energy supply of the future.elia.be)

This project once again demonstrates how quality products, technical expertise, and strong partnerships together make a difference in complex infrastructure works.

“This project perfectly demonstrates where horizontal directional drilling makes a difference today. Over a route of dozens of kilometers, we can realize a new high-voltage connection with a minimal impact on the environment. For the successful execution of a project of this scale, strong cooperation with our suppliers is crucial. Deschacht distinguishes itself through its flexibility, prompt follow-up, and ability to always think along to arrive at the best possible solution, says Edis Karadan, project manager.

Suggestion for a quote by Nick

“In an HDD project of this scale, quality, delivery reliability, and good cooperation are crucial. With Deschacht, we found a partner that meets our expectations in all areas.”
