The cable is the standard grey twin and earth - its in blue water pipe to protect it and to keep it in a more rigid position. I will sprey it black later on.
Well i didnt bother with digging it into the ground for a few reasons
1) The time and effort in doing so
2) I didnt feel the need to do it as currently its elevated close to 3.5m above the ground
3) 6mm twin and earth cost me £80 for 50m! Running an additional 11m of it just to get it under ground really aint worth it
4) I am, sooner or later, building an extension on to that side of the house so it's not LONG term building i am doing just now anyway
I do, however, need to start digging for my drainage and water supply/drainage....
