Impact Moling in Dorchester

What the work involves

• Launch and reception pits at each end of the run
• A pneumatic mole driven along the planned line and depth
• New MDPE pipe drawn through in the same pass
• Pit reinstatement — the surface between them untouched

When you need it

• Replacing a supply under a driveway, path or established garden
• Crossing where excavation would be slow or expensive to reinstate
• Runs up to ~20m per shot in suitable soils
• Any job where the surface above must not be disturbed

What impact moling costs in Dorchester

Moling typically prices at £60–£150 per metre plus the launch and reception pits at each end. Ground conditions, pipe diameter and reinstating the two pits — especially in paved surfaces — move the number; connection work at each end is often the larger cost, so check what the metre rate includes.

When moling wins

Moling almost always wins under driveways, paths and established gardens, because open-cut trenching pays twice — once to dig and once to reinstate. Under a plain lawn, compare quotes: short excavations can compete. And for longer or curved runs — under roads or whole gardens — a related steerable technique, horizontal directional drilling, is used instead; quotes name whichever fits. Very short runs, congested ground and some soils rule moling out, which contractors confirm before quoting the method.

How the work proceeds

The sequence on the day: two pits are dug at the launch and reception points; the mole is aligned and driven, hammering a bore between them; the new MDPE pipe is drawn through behind it; connections are made at each end; and the pits are backfilled and reinstated. A typical house-length run is completed in a day.

Impact Moling in Dorchester — common questions

What ground suits moling?

Clay and most firm, settled ground mole well. Very loose sand, waterlogged ground or heavy rubble/rock can deflect the mole — your contractor assesses on survey.

Can every pipe be moled?

No — congested ground with other services, very short runs and some soil types rule it out. Feasibility is confirmed before the method is quoted.

Does the metre rate include connections?

Often not — the rate usually covers the bore and pipe, with connections, fittings and any water company work at the boundary as separate lines, so ask what is included.
