A smarter way to work underground

Installing underground pipework does not always mean excavating a continuous trench from one end of the property to the other.

Impact moling is a trenchless installation method that creates an underground bore between carefully positioned access points. New pipework can then be installed through the created route.

Where ground conditions and the project allow, this can significantly reduce the amount of excavation required across gardens, driveways and other areas.

Why use impact moling?

The main advantage is simple. Instead of opening up the entire route, work can be concentrated around smaller access points where the method is suitable.

Reduced Excavation

Pipework can be installed between access points without excavating a continuous trench along the entire route.

Less Surface Disruption

Reducing open excavation can help limit disruption across driveways, gardens, patios and other surfaces.

Underground Pipe Installation

The method creates an underground route through which suitable new pipework can be installed.

Planned Around the Site

The route and access points are considered around the individual property, ground conditions and work required.

Contact our team

Small access points. One underground route.

Impact moling works by creating a bore through suitable ground between a launch point and a reception point.

The mole travels underground and compacts the surrounding soil to create a route for the new pipework. The exact layout, distances and access required depend on the site and the installation.

Where can impact moling be used?

Suitability depends on the project, ground conditions, route and surrounding infrastructure.

Water Supply Pipework

Installation of new underground water supply pipework where trenchless installation is suitable.

      Trustindex verifies that the original source of the review is Google. Great service.  Had a horrible underground leak. Enquired with them.  But as they were very busy there was a long wait.  I called back asking if they could prioritise us as the leak was so bad the shower wouldn’t work. They came out much quicker, the two lads who came and, I apologies I’ve forgotten their names, just got on with. No mess when they had finished, they were happy to explain when I asked what they were doing.  Can’t recommend them highly enough. Thanks again Jayne  Ste and the team.

     Trustindex verifies that the original source of the review is Google. This is an amazing company! I’ve been thinking all day how to word my review and can only come up with the old saying that I’m gobsmacked! I had lead pipe replaced by Ardent, a job I believed would be a nightmare. The survey was carried out by two lads who knew their stuff and assured me the job would be done with minimum disruption. But you know what more than anything they were as my son would say ‘top lads’ highly respectful and reassuring.
I was told the lads would be at my house by 8.30 on Sunday and they were there on the dot, started work right away and worked until the  job was done. When we looked out to see the finished job there was no sign of any disruption, not a speck of soil/ dust/gravel etc.
if I hadn’t seen the photos of each stage of the work I wouldn’t have known anything had been done. And you know what these two lads were as good, professional and respectful as the surveyors.
The ethos in this company flows through every employee and that is to provide exceptional customer service.
The work  was done yesterday and by 10 this morning the girls in the office have emailed to me and UU all the documents needed to validate the work.
Apologies for long review, if this was an Oscar winners speech I’d have been pushed off the stage but I really want to emphasise how brilliant this company is, my husband and I are like two old cranks excited about our new water pipe.
Thanks for everything and the very best of luck

A huge thank you to Mark, Steve, and the whole team for an absolutely outstanding job installing our new underground water pipes.

From the first day to the last, they were professional, friendly, punctual, and kept us informed every step of the way. The workmanship was first class, and they left everything spotless when they finished. You genuinely wouldn’t know they’d been there—everything was put back exactly as it was.

It’s rare to find a company that takes so much pride in their work, and it really shows. The attention to detail and the care they took throughout the entire job were second to none.

I honestly can’t recommend them highly enough. A fantastic team delivering exceptional service from start to finish. 110%—thank you all for a brilliant job!

     Trustindex verifies that the original source of the review is Google. Great company and great work. They team at the office were great in dealing with my husbands OCD questions, and the guys who arrived on time, were very polite, got the job done well, avoiding all the underground obstacles in the way of our new water pipe. They tidied up well  and you'd struggle to see they'd been, other than the sparkly new pipe and tap in our outbuilding. Couldn't ask for better. Highly recommended.

     Trustindex verifies that the original source of the review is Google. I cannot praise the company enough. They work they did on our rear garden to stop the surface water laying there is first class. Moreover, the garden looked as good after they finished as it did before. I am delighted with the outcome. Thank you Ardent Utilities

     Trustindex verifies that the original source of the review is Google. I fully echo the positive reviews shared here. I appointed Ardent Utilities to replace an old lead water main, and the service from start to finish was outstanding. From the initial communication with Kirsty to the site inspection with Mark, and finally the work carried out by the team on the ground — every stage was handled professionally and efficiently. The work was completed to a high standard, and the site was left clean and tidy. I wouldn’t hesitate to recommend Ardent Utilities and would gladly use them again.

Mark came out and gave me an estimate for replacing a water supply pipe to my property, which was a really great price. The work was done with no fuss. The 2 guys were very polite and professional  executed the job brilliantly infact so good you couldn't tell they had been.

Our process

A clear approach to assessing the route, planning the installation and completing the underground work with disruption kept to a minimum.

Assess the project

We look at what needs to be installed, the proposed route and the areas the pipework needs to pass through.

Plan the route

The underground route and suitable access points are planned around the individual site.

Create the bore

Where impact moling is suitable, the underground bore is created between the planned access points.

Install the pipework

The new pipework is installed through the route and the required associated works are completed.

Frequently asked questions

Straightforward answers to common questions about impact moling, trenchless pipe installation and what to expect from the work.

What is impact moling?

Impact moling is a trenchless installation method used to create an underground bore between access points. Suitable pipework can then be installed through the created route.

Does impact moling mean there is no digging?

No. Access points still need to be created for the installation. The advantage of impact moling is that it can reduce the need for a continuous open trench along the entire route.

Can impact moling be used under a driveway?

It can be suitable for routes beneath driveways and other hard surfaces, depending on the ground conditions, route and individual project requirements.

What pipework can be installed using impact moling?

Impact moling can be used for suitable underground pipe installations, including water supply pipework. The right installation method will depend on the pipework, route and individual site.

Is impact moling suitable for every property?

No. Suitability depends on factors such as the ground conditions, underground route, surrounding infrastructure and the work being carried out. We assess the project before deciding on the appropriate approach.

Will impact moling reduce disruption to my garden or driveway?

Where impact moling is suitable, it can reduce the amount of open excavation required across gardens, driveways and other finished surfaces.

Do you also carry out the associated civil works?

Yes. Ardent Utilities can carry out the associated excavation and civil works required as part of the wider underground installation.
