What are suitable/ recommended materials to backfill trench to cover main incoming electrical cable?
The MDPE and Gas pipe are in close proximity too
I have some of the following materials spare
- Soil (but it gas tiny rocks in there)
- Sand (building/ plastering sand which has been mixed together)
When backfilling does one need to do any additional steps like compacting at certain stages?
