Directional drilling is used to install water supply lines, including potable water mains and distribution pipelines.
HDD allows for the installation of water lines beneath obstacles such as roads, existing infrastructure without the need for disruptive open-cut excavation.
It provides a cost-effective and efficient method for extending water service to new developments or areas with limited access.
Wastewater Services
Installation of sanitary sewer lines, sewer mains, and wastewater collection systems.
HDD enables the installation of sewer lines in densely populated urban areas, environmentally sensitive areas, and areas with limited space for traditional excavation.It minimizes surface disruption, reduces the risk of environmental contamination.
Stormwater Services
Installation of stormwater drainage systems, including storm sewers, culverts, and drainage pipelines.
HDD allows for the installation of stormwater infrastructure beneath roads, highways, railways, and environmentally sensitive areas with minimal disruption to surface traffic and vegetation.
Electrical & Communications
Installation of underground electrical conduits, communication lines cables, and transmission lines in urban areas, suburban developments, and rural communities without disrupting surface traffic or causing property damage
What is Directional Drilling?
Horizontal directional drilling (HDD), is a minimal impact trenchless method of installing underground utilities such as pipe, conduit, or cables in a prescribed underground path using a surface-launched drilling rig. Directional boring offers significant environmental advantages over traditional open trench methods. The technique is routinely used when conventional trenching or excavating is not practical or when minimal surface
Directional drilling can be utilized with various pipe materials such as PVC, polyethylene, polypropylene, etc but based on the ground conditions and ductility factor in the Polyethylene pipes are most commonly used provided that the pipe's properties (wall thickness and material strength) enable it to be both installed and operated (if applicable) under acceptable stress limits.
Directional boring/HDD is generally accomplished in three principal phases. First, a small diameter pilot hole is drilled along a directional path from one surface point to another. Next, the bore created during pilot hole drilling is enlarged to a diameter that will facilitate installation of the desired pipeline. Lastly, the pipeline is pulled or pushed into the enlarged hole, thus creating a continuous segment of pipe underground exposed only at the two initial endpoints.
Horizontal directional drill (Thrusting) is an innovative technique allows for the installation of infrastructure such as such as Stormwater drainage , Sanitary Sewer, Power, Telecom, Water and Gas etc beneath obstacles such as roads, rivers, railways, and environmentally sensitive areas, minimizing disruption to surface structures and reducing environmental impact .The process of HDD can achieve minimal disruption, Traffic obstructions, Ground contamination, Noise issues, Multiple utilities can be installed in one go.
The process allows to provide more cost effective solutions with job completion archived lot faster without the need for traditional open-cut excavation.
The HDD process begins with the drilling of a small-diameter pilot hole from the entry point to the exit point using a specialized HDD rig
The drill operator uses guidance systems to steer the drill head along the desired path
On Grade drill shots the guidance systems provide real-time information about the drill head's location, orientation, and direction, allowing the operator to adjust the drilling angle and direction as needed
Once the pilot hole reaches the exit point, the drill bit is removed, and larger diameter reaming tools are used to enlarge the hole to the desired size
As the utility or pipeline is pulled back, drilling fluid (typically a mixture of water and bentonite clay) is circulated through the bore hole to lubricate the pipe, stabilize the bore hole walls, and carry cuttings back to the surface
Once the utility or pipeline is successfully installed, the bore hole is typically backfilled with drilling fluid or grout to stabilize the surrounding soil and prevent ground subsidence
Surface structures and landscaping are restored to their original condition, minimizing disruption to the surrounding environment and infrastructure
