The most efficient and precise solution for carrying out horizontal borings in demanding environments.
Installing underground utilities in urban, interurban, natural, and protected areas requires solutions that are more efficient, faster, and have a lower environmental impact.
In this context, Horizontal Hammer Boring (HHB) has become an essential alternative for executing horizontal borings without the need for open trenches. Catalana de Perforacions is a pioneer in introducing this technique to the Spanish market, offering precision and reliability even in the most challenging ground conditions.
What is HHB technology?
The Horizontal Hammer Boring technology is a trenchless horizontal drilling method developed by GEONEX, designed to bore through all types of ground, including those with complex or heterogeneous geological conditions.
Its auger-driven propulsion system enables progress along the planned trajectory while ensuring a clean, precise, and efficient bore.
This technology stands out for its capacity to execute borings of:
- 10 to 100 metres in length
- Diameters ranging from 139 mm to 1,200 mm
The final accuracy depends on the ground conditions and the length of the bore, but it remains exceptionally high compared with other trenchless techniques.
How does it work?
The HHB system drills using helical augers, designed to:
- Ensure stable progress, even in non-homogeneous ground
- Prevent over-excavation
- Maintain constant gradients, which is particularly useful for installations requiring controlled inclinations
Unlike other trenchless methods, the HHB system is fast, clean, and efficient, minimising surface impact.
Main applications of the solution
HHB technology is extremely versatile. Its key applications include:
- Installation of primary utilities: electricity, gas, water, telecommunications
- Sewer installation
- Crossings beneath roads, rivers, railways, and more
It is ideal for projects where traffic cannot be interrupted, where protected areas must be preserved, or when ground conditions pose challenges for other techniques.
Advantages of HHB Technology
The HHB drilling system offers several advantages that make it an optimal solution for many projects:
- Efficient and innovative: Capable of drilling through any type of ground or geological formation while avoiding unnecessary over‑excavation.
- Facilitates pipe installation: This solution is designed for installing steel pipes up to 100–150 metres in length and polypropylene pipes up to 60 metres.
- High precision: Enables constant gradients and maintains controlled trajectories even in variable ground conditions.
An essential technology for demanding projects
The combination of precision, performance, and adaptability makes HHB a key solution for complex projects, infrastructure crossings, and environments where excavation is particularly challenging, establishing it as an essential technique in horizontal drilling.
