Horizontal Directional Drilling (HDD) is a trenchless method used to install underground pipes, cables, or conduits with minimal surface disruption.
Common pipe types include HDPE, PVC, steel, and ductile iron, used for water, gas, telecom, and electrical installations.
* No open trenching
* Minimal traffic disruption
* Suitable for crossing roads, rivers, railways
* Environmentally friendly
* Faster project completion in urban areas
Yes. Proper survey, mapping, and use of guided drilling technology help avoid damaging existing underground utilities.
Lengths can vary from a few meters to several kilometers, depending on the soil conditions, equipment used, and pipe size.
HDD works well in a variety of soil types including clay, sand, gravel, and even soft rock. However, a geotechnical survey is recommended.
Yes, HDD is ideal for congested zones due to its no-dig nature, making it ideal for cities and developed areas.
Yes, permissions are typically required from local authorities, municipalities, or railway/highway departments depending on the project scope.
Modern HDD rigs use tracking systems to achieve high accuracy in bore path alignment and depth control.
Pipes like HDPE or steel laid using HDD can last 50–100 years depending on material quality and usage conditions.
