Horizontal Directional Drilling Oxfordshire
Horizontal Directional Drilling (HDD) is a trenchless method used for installing underground utilities such as water, gas, electrical, and communication cables. This technique is commonly used in places like Oxfordshire, which is a large and growing urban area in the UK. The main advantage of HDD is that it allows the installation of pipes and cables without the need for extensive digging or disruption to the surface, making it ideal for use in areas where excavation would be challenging, disruptive, or expensive.
In Oxfordshire, HDD might be used in urban and rural settings, helping to minimise the impact on traffic, residents, and businesses. The method is particularly useful in areas with limited space, like busy roads, parks, or environmentally sensitive areas, where traditional open-cut trenching would be impractical or damaging.
What is Directional Drilling?
Horizontal Directional Drilling (HDD) is the technique we use to install underground utilities, such as pipes, cables, or conduits, without the need to dig long messy open trenches. Instead of traditional trenching methods, Directional Drilling creates underground pathways with minimal surface disruption that utilities like Water pipes, Electric Cables and Conduits can be installed underground.
It’s a fast, cost effective solution that is perfect for installing utilities underground where there are obstacles like roads, rivers, trees and wildlife or buildings. Horizontal Directional Drilling is one of the most cost effective methods for underground installations.
What is the
Horizontal Directional Drilling Process?
Before starting, we determine the best route for the bore, considering factors like existing infrastructure, soil conditions, and environmental impacts. Entry and exit pits are excavated from which a pilot hole is drilled, using specialist drilling equipment that is guided by a tracking system. The pilot hole follows a predetermined path.
After the pilot hole is drilled, it’s enlarged by pulling larger reamers through the hole to accommodate the size of the pipe or cable to be installed. Once the hole is the desired size, the pipe or conduit is pulled back through the hole.
From planning to execution, our experienced team focus on expert underground installations, while minimising environmental impact and maximising productivity.

About Oxfordshire
Oxfordshire is a county located in the South East of England, known for its charming countryside, historical landmarks, and the famous University of Oxford. The county is bordered by several others: Northamptonshire to the north, Buckinghamshire to the southeast, Berkshire to the south, Wiltshire to the southwest, and Gloucestershire to the west. The county is renowned for its natural beauty, with scenic areas like the Cotswolds and the Chiltern Hills, as well as picturesque towns such as Abingdon, Banbury, and Witney. Oxford itself, the county town, is home to the University of Oxford, one of the oldest and most prestigious universities in the world, which adds to the area’s cultural significance.
Oxfordshire has an estimated population of around 690,000 people. The largest city is Oxford, but the county is also known for its smaller market towns and rural villages, such as Dorchester-on-Thames, Great Tew, Witney, Bampton, Stanton Harcourt.
The main largest towns in Oxfordshire are Banbury, one of Oxfordshire’s largest towns and famous for the “Banbury Cross” nursery rhyme. Abingdon located on the River Thames; Abingdon is one of the oldest towns in England. Witney, a large market town in the west of Oxfordshire. Didcot, home to the Didcot Railway Centre and good transport links to Oxford and London. Bicester, known for its famous Bicester Village shopping outlet. Henley-on-Thames, notable for its picturesque setting along the River Thames and its world-famous Henley Royal Regatta. Wallingford, a historic market town situated on the River Thames.
What is Horizontal Directional Drilling (HDD) used for in Oxfordshire
Horizontal Directional Drilling (HDD) is a trenchless technology used to install underground utilities and infrastructure without the need for extensive excavation. In Oxfordshire, Horizontal Directional Drilling is regularly used to lay pipes for water and gas, as well as cables for electricity and telecoms. The technology allows utilities to be installed underground without disrupting the surface, making it ideal for areas with busy roads, sensitive landscapes, or historic sites (like those found in Oxfordshire). Horizontal Directional Drilling is commonly used to install utilities under roads, rivers, or other obstacles where traditional trenching would be difficult or damaging. In Oxfordshire, this can be particularly useful for crossing roads or natural features like the River Thames without having to dig up the road or riverbank. Given the rural and historically sensitive nature of many areas in Oxfordshire, Horizontal Directional Drilling is often used to minimise the environmental impact of infrastructure projects.
Ground conditions for directional drilling in Oxfordshire
The ground conditions in Oxfordshire vary widely depending on the location, which can influence the feasibility and efficiency of Horizontal Directional Drilling (HDD) projects. In many parts of the county, particularly in the south and southeast (including areas near the Chiltern Hills), the bedrock consists of chalk and limestone. These can be challenging to drill through, as they can be quite hard and may require more advanced HDD techniques. In some areas, particularly along the River Thames and in the Oxfordshire plain, the ground consists of soft clays and silts. These conditions are generally favourable for HDD, as they are easier to bore through. Areas with sand and gravel, often found in riverbeds or as glacial deposits, provide relatively easy drilling conditions. However, loose sand can present challenges in terms of maintaining the borehole integrity and preventing the collapse of the hole during drilling.
The Oxford Clay formation, found in various parts of the county, is a type of mudstone that can be relatively soft and easier to drill through. However, like other clay-rich soils, it can become sticky and difficult to work with in wetter conditions, potentially leading to issues such as borehole instability.

Directional Drilling Case Studies
Benefits of Directional Drilling
Limited Surface Disturbance
Directional drilling reduces the need for extensive excavation, minimizing disruption to surface environments such as landscapes, vegetation, and wildlife habitats.
Preservation of Fragile Areas
By avoiding traditional excavation, directional drilling helps protect environmentally sensitive regions like wetlands, forests, and habitats, safeguarding biodiversity and species.
Conservation of Urban Greenery
In cities, directional drilling preserves parks, green spaces, and trees by minimizing disturbance during utility installations, maintaining valuable urban green infrastructure.
Prevention of Soil Erosion
Traditional excavation can destabilize soil, leading to erosion and sediment runoff. Directional drilling minimizes soil disturbance, helping to prevent erosion and preserve soil health.
Protection of Water Quality
Directional drilling reduces the risk of water pollution by minimizing soil disturbance and sedimentation, thereby safeguarding nearby water bodies and ecosystems.
Reduced Carbon Footprint
With fewer heavy machinery and transportation needs compared to traditional methods, directional drilling helps mitigate carbon emissions and air pollution, contributing to a cleaner environment.
Utility Pipe Tracing and Surveys
As we replace services underground, we are faced with multiple dangers such as electric cables and gas pipes. Our specialist equipment locates other utilities such as these to ensure a safe comprehensive installation, avoiding other existing underground installations.
We use tracer cables to help us locate plastic pipes and drainage systems. We can determine as the depth of the other services, in order to avoid them and also locate them for our clients.
To locate and assist other companies with underground works we carry out full mapping of large areas such as estates and car parks.
Multi-Utility Installations
We utilise the same no-dig methods and equipment to install a wide range of underground services.
For example, we install water, gas, electric, data, fibre and drainage using moling and directional drilling trenchless technologies.
We also use trenching methods where trenchless methods are not viable.
We have carried out multi-utility installations for domestic customers, utility providers, commercial clients and even railway projects.
