Drilling under road

In the past, when one had to drill under the road to replace or install pipelines or cables, this often involved excavation work. Today, there is an efficient way to drill under roads: horizontal directional drilling (HDD). This is an innovative method that involves trenchless drilling without using traditional vertical excavation techniques. Horizontal directional drilling involves the use of advanced drilling equipment and precise positioning technology to guide the boring. The precision of this method allows for safe drilling under roads to install pipes and cables.

One of the advantages of drilling under roads with horizontal directional drilling is that the daily traffic and the surrounding community are not disturbed. In addition, horizontal directional drilling reduces ecological impact, as there is less ground displacement and destruction of landscapes. Moreover, HDD also allows for longer and more challenging drilling projects.

Since 1994, Brownline has been developing innovative technologies for various applications, including drilling under roads. We developed our Drillguide Gyro Steering Tool to enable safe and accurate underground drilling. Based on gyro technology, the tool measures the position of the drill head very accurately and in real time. Our steering service offers a suitable solution for all kinds of drilling projects and is used all over the world, for example in these projects:

• Challenging curved HDD in the middle of Florence: To replace a network of high-voltage power lines, it was necessary to drill under a busy intersection. We surveyed a challenging drill path with s-curve and the pilot phase of the project was completed using our Drillguide Gyro Steering Tool.

• Gas pipeline with large curvature in Luxembourg: For the installation of a gas pipeline, we surveyed a drilling with a curve of 67 degrees. This pipeline was installed under a highway. Our Drillguide Gyro Steering Tool was used to control as accurately as possible whether the planned curve was followed.

• Extreme urban crossing in the heart of Miami: Brownline USA was a major contributor to a challenging trenchless project in the middle of Miami. Laying underground power cables in such a busy urban area, required accuracy during the pilot bore. Thanks to our Drillguide Gyro Steering Tool with Radar add-on, the drilling was completed successfully.

Since 1994, Brownline has been developing measurement and navigation technologies that stand out for their accuracy, reliability and ease of use. With our Drillguide Gyro Steering Tool, we provide a solution that makes navigating through increasingly complex underground infrastructure significantly safer and more efficient. The tool is part of our complete steering service. With our advanced technology and years of experience, we ensure that every drilling project can be executed with precision.

More than 25,000 projects around the world have already been successfully completed using our tools and add-on modules. Want to know how our steering service can enhance your drilling project? We’re happy to help.
