I'm about to bury armoured cable, armoured ethernet cable and mdpe water pipe running from my house then under a kitchen extension, under patio and lawn to an outbuilding, total distance about 20m. The posts I've read here only seem to consider the electric cable but not the water pipe together.
I'm not too sure how deep I should lay each type of cable and what type of aggregates I should surround each type of run. I have an 80cm trench already dug. I've seen different types of options and cross section drawings on the net but I'm not clear on the best method.
I purchased the following items from TLC
SW16/3 16.0mm⊃2; 6943X 3 core SWA Steel Armoured Cable
CACAT5E/SWA CAT5e - 4pr External Steel Wired Armoured Cable
FMPT103 Electric Cable Below Tape 150mm x 365Mts
At first I going to lay the water pipe in backfilled soil at 80 cm, followed by the electric cable and ethernet cable in sand (or pea shingle?) at 45cm but slightly offset from the water pipe. Finally the warning tape.
Your kind advice would be highly appreciated, thanks in advance.
