Horizontal Directional Drilling (HDD)

​

Pipeline Drillers specialises in Horizontal Directional Drilling (HDD), a guided, trenchless technique for installing underground pipelines, cables, and ducts. Ideal for pipe sizes ranging from 25mm to 900mm in diameter and distances of several hundreds of metres, HDD is a surface-launched method requiring no deep excavations. With a minimal footprint, it works across various ground types, making it a versatile and efficient solution.

​

HDD is perfect for projects in environmentally sensitive areas, congested spaces, or locations where traditional methods are costly or impractical. Applications include water mains, pumped sewers, gas and oil pipelines, and utility cables, especially under roads, railways, waterways, and existing structures.

​

Why Choose Horizontal Directional Drilling?

• Versatility: Works in challenging locations, including under roads, rivers, and railways, with no surface disruption.

• Cost-Effective: Requires no intermediate pits, reducing overall project costs.

• Precision: Pipes can be installed in straight or curved paths to avoid obstacles and existing services.

• Minimal Environmental Impact: No scarring of the landscape or disruption to traffic, and it’s safe for environmentally sensitive areas.

• Efficient Installation: Suitable for short, medium, and long pipelines with minimal surface disturbance.

​

How It Works

HDD involves drilling a pilot borehole along a pre-determined path. Once the pilot hole is complete, the borehole is enlarged to accommodate the required pipe size. This process ensures precise installation with minimal disruption.
