Trenchless Solutions
Horizontal Directional Drilling Technology
Horizontal Directional Drilling (HDD) is a trenchless method for installing underground pipelines, conduits, and cables with minimal environmental impact and surface disruption.
What is HDD?
HDD is a steerable trenchless drilling technique used to install underground pipes, conduits, and cables along a predetermined path. It's ideal for crossing obstacles like rivers, roads, and environmentally sensitive areas without disruptive excavation.
HDD Process Overview
- Pilot Hole: Drilling a small diameter pilot hole along designed path
- Reaming: Enlarging the hole to required diameter
- Pullback: Pulling the pipeline through the reamed hole
- Final Connection: Connecting to existing infrastructure
Key Applications
- Utility installations under roads and highways
- River and water body crossings
- Environmental and protected area crossings
- Urban infrastructure development
- Telecommunications and fiber optics
Technical Specifications
Drilling Length: Capable of installations from 100 to 5,000+ feet
Pipe Diameter: Accommodates pipes from 2 inches to 56 inches
Depth Capacity: Can drill at depths up to 200 feet below surface
Major Advantages
- Minimal surface disruption and restoration costs
- Reduced environmental impact
- Faster installation compared to traditional methods
- Ability to cross obstacles without disruption
