No-Dig Solutions
Repair Your Drains Without the Mess
The biggest fear most people have when they hear “drain repair” is the thought of excavators tearing up their driveway, or a trench running through their new patio.
At ASL, we use modern No-Dig Technology (also known as trenchless technology) to solve drainage and water supply problems without the destruction.
In simple terms: We may be able to fix a drainage problem underground without excavation, or install a new water supply pipe with minimal surface disruption.

Why Choose No-Dig?
Gone are the days when every broken pipe required a massive hole in the ground. Customers choose our no-dig methods because they are:
- Cleaner: We protect your garden, driveway, and paths.
- Faster: No digging means less labour and a quicker turnaround.
- Cheaper: You save money on repaving, concreting, or relandscaping after the job is done.
- Less Disruptive: We can often fix pipes located underground without disturbing surface areas.

Our No-Dig Services
We offer a range of trenchless solutions depending on whether you need to fix a drain or install a new water pipe.
1. Drain Lining (CIPP – Cured-in-Place Pipe) – The “New Pipe Inside an Old Pipe” Solution. If your drain is cracked or leaking, we insert a specialist resin sleeve into the pipe. We inflate it and let it harden, creating a tough, waterproof new pipe inside the damaged one.
Best for: Cracks, fractures, leaks, and preventing tree roots returning.
2. Moling – The Tunneling Solution for Water Mains. Need a new water supply pipe? Instead of digging a trench from the street to your house, we dig a small pit every 10m or so and use a pneumatic “mole” to tunnel underground between them. We then pull the new pipe through the tunnel.
Best for: Replacing lead water pipes or installing new water supplies under driveways and lawns
3. Pitch Fibre Re-Rounding – The Reshaping Solution. Many older homes have Pitch Fibre pipes that deform and blister over time. We use a specialist tool to restore the pipe back into its original round shape from the inside, before lining it to lock it in place.
Best for: Squashed or blistered drainage pipes (common in 1950s – 1970s builds).
4. Milling & Root Cutting – The Internal Heavy-Duty Clean. While technically a cleaning method, this is a vital part of the no-dig process. We use robotic cutters to grind away concrete, heavy scale, or tree roots from inside the pipe to prepare it for lining.
Best for: Removing hard obstructions without excavation.
When Is No-Dig the Best Option?
We recommend trenchless methods whenever possible, especially if:
- The pipe runs under a surface you don’t want disturbed.
- The pipe is damaged but hasn’t completely collapsed.
- You want to avoid the cost and mess of reinstatement (re-paving/concreting).
A Note on Honesty: No-dig technology is amazing, but it can’t fix everything. If a pipe has fully collapsed or is crushed flat, or there are multiple underground services which are at risk of being damaged by moling, we may still need to excavate. However, if we can save it without digging, we always will.

The Benefits to You
- Minimal Disruption: Life continues as normal while we work.
- Long-Lasting: Our structural liners are designed to last for decades.
- Eco-Friendly: Less heavy machinery and less waste material to dispose of.
- Cost-Effective: Smart technology saves time and money.
Save your surfaces and solve your drainage problems with ASL.
ASL selects the most appropriate trenchless method based on the condition of the pipe and the customer’s requirements.

What Our Clients Say
“I called at 08:10 hours to report a blocked drain. A little while later, Darren rang to tell me he’d arrive in half an hour. He arrived on time and resolved the problem quickly and without fuss.

“I unreservedly recommend ASL. All the glowing reviews of ASL are true. They had to lift paving slabs to fix my drains, and I was concerned there might be unavoidable damage. I should not have worried. Liam and Richard did a superb job. Thanks, ASL” Customer, Surrey
“Darren arrived very promptly and got to work quickly. He did an excellent job and explained what he was doing. We would have no hesitation in recommending ASL Services.” Customer, Surrey
“Very efficient to book them to sort out a sewer drain blockage, and the cost was exactly what they quoted. Called before they arrived with a clear ETA. Got on with the job and sorted it out within the hour. Darren was excellent – very courteous and helpful, did more than we expected to help sort the problem out and was a font of knowledge on all things sewer-related. Given the subject matter (eeew) the whole experience with ASL was an absolute pleasure.” Customer, Surrey
“ASL recently carried out a drain repair at our house. They responded quickly to the call for help, came out and soon diagnosed the problem – tree roots blocking the drain. The remedial work on site was carried out by Lester and George – they worked hard and were very thorough. This is a long-established company that seems to know what they are doing.” Customer, Surrey
