When it comes to replacing or installing underground utilities, modern trenchless technology offers efficient and non-invasive methods to get the job done. Two of the most popular techniques in underground drilling are moling and directional drilling. At EPS Trenchless Installations, we specialise in both, providing reliable trenchless solutions for utility installations and replacements across the UK. But how do these underground construction methods differ, and which is best suited for your project? Let’s break it down.
Moling, also known as mole digging, is a trenchless technique that uses a pneumatic device, often referred to as a “mole” or “pipe mole,” to create small tunnels underground. This moling machine is particularly popular for installing or replacing utility pipes and cables without the need for extensive excavation. By avoiding open trenches, moling allows for quick and efficient installation with minimal disruption to the surrounding area.
Minimal excavation reduces labour, material, and reinstatement costs.
Ideal for smaller projects or installations over short distances.
Perfect for residential areas where maintaining the existing landscape is crucial.
Moling is commonly used for domestic installations or replacements of utilities such as:
for homes and properties
ensuring safe and reliable delivery of energy.
particularly in residential developments.
It’s particularly effective in areas with soft ground conditions, such as clay or sand, and is best suited for distances of up to 25 metres. Moling is often the go-to solution for homeowners and small-scale contractors looking for an efficient, budget-friendly option.
Directional drilling, also known as horizontal directional drilling (HDD) or HDD drilling, is a more advanced trenchless method that involves using a steerable drill head to create precise underground bores. Unlike moling, directional drilling can follow curved paths, making it incredibly versatile and suitable for complex installations.
Capable of handling longer distances and challenging ground conditions, including gravel and rock.
Allows for navigation around existing utilities, obstacles, and sensitive areas, such as under roads, rivers, or buildings.
Suitable for installing larger-diameter pipes or multiple cables simultaneously.
Directional drilling is widely used for a variety of commercial, industrial, and municipal projects, including:
ensuring high-speed connectivity.
for large-scale energy distribution.
replacing aging infrastructure or installing new supply lines.
especially in densely populated urban areas.
This method excels in projects where traditional excavation would be impractical or too disruptive, such as busy city centres or environmentally sensitive areas. The directional driller can use a compact drilling rig to perform horizontal drilling in tight spaces, making it ideal for urban environments.
Choosing between moling and directional drilling depends on the specific needs of your project. Here’s a breakdown of key factors to consider:
Best for small-scale domestic projects, such as installing a single utility pipe or cable.
Ideal for large-scale projects requiring precision and longer installations, such as utility upgrades for commercial developments or industrial facilities.
Works well in soft soils, such as clay, sand, or silt.
Suitable for a wider range of ground conditions, including rocky or compacted soil.
Effective for short distances, generally up to 25 metres.
Capable of covering hundreds of metres, making it the preferred method for long or complex routes.
More budget-friendly for smaller, straightforward jobs. The impact moling cost is generally lower than other methods.
More budget-friendly for smaller, straightforward jobs. The impact moling cost is generally lower than other methods.
Both methods provide unique advantages, and the choice will depend on your project’s specific requirements, budget, and timeline.
