Trenchless Moling

What Is Moling?

Moling, impact moling, trenchless moling are all the same and is trenchless method used to lay pipes. The process involves a pneumatically-driven machine known as a mole forcing its way through the soil along the desired path of the pipe. Moling is used extensively by all civil engineering and utility services for laying of their pipes and cabling.

At JD Moling – External Moling Services Surrey, we use our moles to form a bore underground that the new pipe work can then be pulled through. This is a fast and efficient method of installing new pipes, saving both labour and materials when compared to traditional trench excavation. 

Why Use Moling?

Our trenchless method involves excavating pits at intervals for the mole to be placed instead of digging trenches to lay pipes/ducts and cables.

The mole is then entered into the earth on the horizontal face at the bottom of the pit. Destination pits of similar proportions are also dug, and this is where the mole emerges. The mole itself is a steel cylinder, it works as a pneumatic cylinder with pulsed compressed air causing the head of the mole to repeatedly hammer against the soil in front of the mole. The mole displaces the soil creating a bore for the new services to then be pulled through.

The overall benefit is a reduction in the installation time, ground disturbance and cost.

Our Stages


We start with a detailed survey, site visit and the use of online technology to check geological information around your project.


From conception to completion JD Moling work in partnership with you, planning and advising you on the best way to complete your project which will cause the least conviencence, cost and enviromnental repurcussions. 


Our experienced engineers follow our plans from start to finish and carry out the moling process with competence ensuring the job is handled professionally and diligently by our fully qualified engineers

Quicker & Efficient

Our moling and trenchless technology offers a unique way to burrow through the ground for conduits and lead pipe replacement with a significant reduction in surface disturbance. A small pneumatic device burrows and hammers it’s way through the ground to make a channel.

Proven Technology 

Having completed moling projects across Surrey on roads, motorways, rivers and canals, domestic propertes and sporting venues, JD Moling has a proven track record in major underground installation projects in Surrey.

No Surface Distruption

As only excavations of no more than 1 metre square and 1 metre deep are required to introduce and receive the mole, there is no need to disturb the surface, the mole burrows discreetly under gardens, patios and driveways.

JD Moling - External Moling Services - Trenchless Installations

Trenchless Installations

Impact Moling is a technique in which a pneumatic piercing tool is used to create a bore hole. The ground is compacted and displaced rather than excavated and removed, therefore disruption and reinstatement are minimal.
Impact Moling is the simplest and least expensive trenchless technology installation method.

How Do I Know I Have A Leak?

If your property is fitted with an external water meter there is a simple test you can do to check for leaks. Ensure that all appliances and taps are turned off and then monitor the meter.

No dials should move and if they do there may be a leak on the system.

If you assume a leak - If a leak on the water supply pipe is suspected and you are the property owner it is your responsibility to have it repaired or replaced promptly.

Please contact us as soon as you can to avoid water damage to your property.

Causes For Low Pressure?

Leaks - If water is leaking from your system your pressure will drop.
Shared supply pipes - you may experience low pressure during peak periods. An independent supply is highly recommended.
Supply pipe size - a smaller internal diameter will limit the flow rate to the property.
Pipe Corrosion - restricts water flow and can lead to leaks
Heating systems and showers - Many new showers and combination boilers will need a minimum level of flow to work effectively
