Frequently Asked Questions

What is horizontal directional drilling?

Horizontal directional drilling, often referred to as HDD or trenchless technology, is an innovative technique for laying underground utilities such as pipes, cables, ducts, and conduits without resorting to conventional trenching. Instead of creating open trenches, this method starts with a pilot hole that is drilled diagonally from the surface toward a desired endpoint. After the initial hole is made, advanced drilling equipment enlarges and steers the hole in the desired direction while underground. This seamless process provides minimal damage to the surface ground and is not as invasive as conventional methods, saving our clients money and the hassle of restoring the area after large excavation work.

What is the directional drilling process?

Our procedure starts by drilling a pilot borehole that follows a predetermined route. We then expand the hole along the trajectory established by the pilot bore, a process referred to as back reaming. Finally, the product pipe is pulled through the enlarged passage.

What is the horizontal directional drilling machine used?

The machine we will choose for your project is dependent on your site and location. For our smaller and more fragile ecological sites, we will select our smaller HDD machine to ensure that we minimise disruption to the environment and protect delicate ecosystems. This smaller HDD machine is designed to navigate tight spaces and sensitive terrain with precision and care, allowing us to complete the job while minimising impact on the surrounding area.

For larger sites that require greater power and capacity, we have larger HDD machines equipped to handle more demanding projects, whilst still maintaining little impact at your location. These machines are capable of tackling larger bore diameters and longer distances, providing the necessary strength and efficiency to complete the job effectively.

No matter the size or complexity of your project, we have the expertise and equipment to ensure successful horizontal directional drilling while prioritising environmental conservation and minimising disruption to sensitive areas.

What is the purpose of directional drilling?

Directional drilling is utilised for laying utility lines and conduits, providing a more economical and minimally invasive option compared to conventional vertical drilling methods.

This approach provides many advantages over conventional drilling as it is possible to lay or repair utility pipes, ducts, or cables, without excavations of large amounts of ground and provides options for laying pipes in sensitive or protected areas.

What is the benefit of using horizontal and directional drilling?

There are many advantages to employing horizontal and directional drilling. These are, minimal disturbances to surfaces, reduced environmental impact, cost savings, enhanced safety, and provides minimal disruption to utilities.

How far can you drill horizontally?

This is entirely dependent on the machine used for your location and ground conditions and/or obstructions. We will conduct a site visit and discuss the plan of action. Pipes from 25mm to 355mm diameters can be installed over distances of up to 200 metres in a single shot. Ducting, cables, and pipework can also be installed in either straight or curved lines.

Will the location be disturbed by heavy machinery and footfall?

No, it won’t. Our methods and trenchless technology will minimise disturbance in your location. Our approach ensures that we can carry out our work efficiently and effectively while keeping the impact on your surroundings to an absolute minimum. We will conduct a site visit before work takes place, talk through your requirements and we will evaluate the area to identify any obstacles or obstructions that may be present.

If you require work in protected or specialist areas, we can provide minimal disruption to the natural environment, ensure compliance with any relevant regulations or restrictions, and respect the integrity of the site.

Where do you provide the implementation of horizontal drilling?

We provide our expert trenchless solutions across a span of industries in the UK. Our industries include environmental remediation, water management, utility services, civil engineering and construction, and more.
