Impact Moling London — Trenchless Water Pipe Installation Specialists

Looking for New Water Supply Connection in London?

Installation Specialists

Impact moling is the most efficient and least disruptive method for installing underground water supply pipes in London. JD Leak Detection, working alongside our sister company JD Moling Ltd, offer full impact moling services across all London boroughs — replacing lead and supply pipes with virtually no surface disruption.

What is Impact Moling?

Impact moling (also called trenchless pipe installation) uses a pneumatically driven moling tool to create an underground bore through the soil between two small excavation pits. The new MDPE water supply pipe is pulled through this bore, meaning:

• No open trench across your drive, garden, path or patio
• Only two small pits — one at the entry point, one at the exit
• Surfaces remain largely intact — minimal reinstatement required
• Suitable for runs under driveways, paths, roads and established landscaping
• Most jobs completed in a single day

When is Impact Moling Used?

• Lead pipe replacement — installing new MDPE pipe without trench excavation
• Water supply pipe replacement — replacing old, failing or undersized supply pipes
• New water connections — routing new supply pipes to extensions, conversions or new builds
• Shared supply separation — independent supply routes installed without surface disruption
• Long pipe runs — particularly effective for longer distances where a trench would cause major disruption

Impact Moling vs Traditional Open-Cut Excavation

For most London water supply projects, impact moling is the superior choice:

• Faster: most moling jobs complete in one day vs two or more for open-cut
• Cheaper overall: reduced reinstatement costs offset the moling equipment cost
• Less disruption: your drive, garden and landscaping stay intact
• Better for difficult runs: under established driveways, paths and confined spaces

Where pipe routes include tight bends, existing obstructions, or very short runs, open-cut excavation remains the appropriate method — we'll advise on the best approach for your specific job.
