Imagine a hill and then imagine fencing across it horizontally. At a point we have a drive cut into this hill and we have to find a way to continue a fence across the top for a distance of about 6m with a turn half way through.
Currently the previous owners used posts just in the soil on the top of the step but its very unstable. There's a drop of about 60cm off the top to the drive and the earth needs to be held back along this 6m edge.
Help!
