South Africa, Horizontal Directional Drilling Services
Horizontal Directional Drilling
A Horizontal Directional Drilling (HDD) Company that puts your needs first. HDD is mainly for the installation of underground utility pipes, ducts or cables in a straight or curved line without damaging the surface layers. HDD is a trenchless form of drilling that is faster, cleaner and more eco-friendly.

*A HIGHLY SKILLED TEAM OF EXPERTS GETS TO THE CORE OF THE MATTER.
*INNOVATION AND EXCELLENCE IS WHAT SETS OUR SERVICE OFFERING APART.
HORIZONTAL DIRECTIONAL DRILLING SERVICES
Horizontal Directional Drilling (HDD), also known as directional boring or trenchless drilling, is a method used to install underground pipelines, conduits, or cables without the need for traditional trenching methods. It involves drilling a borehole along a predetermined path from the surface, and then pulling the desired utility through the drilled hole.
Horizontal Directional Drilling is commonly used for installing utilities such as water and sewer lines, telecommunications cables, electrical conduits, and gas pipelines. It has become a preferred method for many underground construction projects due to its efficiency, versatility, and minimal environmental impact.
Benefits
Minimal Surface Disturbance:
HDD minimizes disruption to surface infrastructure, landscaping, and traffic, making it ideal for urban areas, environmentally sensitive areas, or locations with existing utilities.
Reduced Environmental Impact:
By avoiding extensive excavation, HDD reduces soil disturbance and the risk of soil erosion or contamination.
Cost-Effectiveness:
While HDD may have higher upfront costs compared to trenching, it can be more cost-effective overall due to reduced restoration expenses and shorter project timelines.
Versatility:
HDD can be used to install various types of utilities, including pipelines, conduits, and cables, across different soil types and terrain features.
Here's how the process generally works:
Planning
Engineers carefully plan the route for the borehole, taking into account factors such as soil conditions, existing utilities, and obstacles. The path typically follows a predetermined horizontal and vertical profile to reach the desired endpoint.
Drilling
A drilling rig is set up at the starting point, which may be above ground or in an access pit. A drill stem with a drill bit is then inserted into the ground and directed along the planned path using guidance systems such as gyroscopic tools, magnetic guidance, or electronic tracking devices. As the drill progresses, it creates a pilot hole.
Pilot Hole Enlargement
Once the pilot hole is drilled to the desired length, it is enlarged to accommodate the size of the utility being installed. This may involve using larger cutting tools or reaming equipment to widen the hole to the required diameter.
Pullback
After the hole is enlarged, the utility, such as a pipeline or conduit, is attached to a pulling assembly and pulled back through the borehole to the starting point. This process can be done simultaneously with the drilling or as a separate step after the pilot hole is drilled.
Connection and Restoration
Once the utility is pulled through the borehole, it is connected to the existing infrastructure at both ends. Access pits are backfilled, and any surface disturbances are repaired.
