How deep do I need to lay the lead-in pipe when I’ve got power in the same trench?
You can find useful information on trenching here. The general guideline is that power goes in first at 550mm deep, dirt or grit 100-150mm deep and then our 20mm green pipe can be laid on top.
Don’t forget the hazard warning tape is to be inputted at approximately 300mm deep. If your trench is only for telecommunications, then aim for 400-500mm deep with a warning tape 100mm above. With fibre we request that you don’t do hard bends – keep it as straight as possible or gentle curves.
