How to Dig a Drainage Trench with a Mini Digger

Whether it’s land drainage, a soakaway run or a service trench, a mini digger makes light work of trenching — as long as you plan it properly.

How to dig a clean trench

1. Mark the run and, critically, CAT-scan for buried services before breaking ground.
2. Choose a bucket to match the pipe and bedding width.
3. Dig to a consistent fall — use a laser level so water actually flows where you want it.
4. Keep the spoil to one side, leaving room to lay pipe and backfill.
5. Bed, lay and surround the pipe, then backfill and compact in layers.

Safety first: deep trenches can collapse — batter the sides or use trench support, and never work in an unsupported excavation. We hire mini diggers and can supply compaction kit too, delivered and collected across Norfolk & Suffolk. Get a quote.
