What is Trenchless Moling?
Trenchless moling (also known as impact moling) is an advanced, non-destructive method of laying underground water pipes. Instead of digging a continuous, messy trench across your entire property, we use a pneumatically driven 'mole' to punch a clean horizontal tunnel deep underground.

Excavation Pits
Instead of a long trench, we carefully dig just two small 1m x 1m pits—one at the boundary and one near your property.
Impact Moling
The pneumatic mole fires through the subsoil between the two pits. We then securely attach the new MDPE pipe and pull it through.
Testing & Reinstatement
We connect the pipe, test the pressure, and fill in the small pits. We ensure everything is fully tested and compliant with UK Water Regulations before leaving your property.
Trenchless Moling FAQs
Common questions about our non-destructive pipe laying services.
What is trenchless moling?
Trenchless moling (or impact moling) is a method of laying underground pipes without needing to dig a continuous trench. We use a pneumatically driven 'mole' to bore a horizontal tunnel beneath the ground, allowing us to pull the new pipe through cleanly.
Can moling go under my block paved driveway?
Yes, absolutely. Moling is designed specifically to go underneath expensive surfaces like block paving, tarmac, concrete, and landscaped lawns, keeping them completely intact.
Are your moling installations fully compliant with water regulations?
Yes. Because our engineers are fully WIAPS (Water Industry Approved Plumbers Scheme) and WaterSafe registered, you can be confident that every new water supply pipe we lay strictly adheres to UK Water Regulations.
How long does the moling process take?
Because we eliminate the need for heavy excavation and surface reinstatement, 95% of our residential moling jobs in Manchester are completed within a single working day.
What size pipes can be installed via moling?
We typically mole standard 25mm or 32mm MDPE (Medium-Density Polyethylene) pipes for residential water mains, which drastically improves your water flow rate and pressure.
