Advantages of the directional drilling technique

  • Quick: A modern drill can drill up to 100m in magnitude in a day.
  • Precise: Modern measurement methods allow for precision as close as 10 cm.
  • Comfortable: In contrast to other technologies where the pavement surface needs milling, drilling saves residents from traffic and noise caused by machinery and trucks, from long-term closure of the area and traffic jams, and helps prevent nuisances arising from other methods. In an area where directional drilling is applied, normal life never stops.
  • Durable: No need to worry about subsequent surface damages or sinkage.
  • Eco-friendly: Nature, as opposed to the milled area, suffers only point-like impacts, minimizing disturbances in the order of the environment. Contrary to open-trench technology, the original vegetation and soil surface remains undisturbed.
  • Directional: In contrast to other technologies that do not use surface milling, directional drilling can be controlled depending on the inflection radius of the drill shank and the soil structure.
  • Cost effective: There is no substantial soilwork and expensive remediation involved; neither is there traffic from machinery, hardly any waste is produced, no need for supporting services or complicated road blocks and traffic regulation methods… Moreover, the client is exempt right from the start from these expenses, not to mention the working hours involved.

Take a look at how the Zolmat Team works!

In the autumn of 2015, Tarr Ltd, the leading cable provider in Tolna County, Hungary, was developing its network, in the course of which a bundle of optical cables was to be installed across the river Danube at the latitude of the town Paks. The cables had to be positioned underground…

What is directional drilling?

Directional drilling is one of the most versatile technologies for laying down pipes without milling, and is a diversified solution in public utility construction.

The essence of the method is to create the passage from the surface, without digging a working trench, then expand it to the desired diameter and insert the product pipe from the outgoing access point.

The drilling itself is performed with a drill controlled from the surface via the rotation and injection of the drill shanks.

A radiosonde in the drill bit sends data about the actual direction and depth to the surface, whereby spatial positioning is calculated.

"There is practically not a single square mile within Hungary where we have not done work in the last 25 years."

Zoltán Varga – Managing Director, Owner



The Zolmat Team has completed 4.3 drills per day on average in 2015, including Sundays and holidays.

60% of our colleagues have been on the team for more than 10 years.
