Turf to one side soil to the other. We were going to go the other side of the wall but it turned out to be a sandstone ridge with 3 or 4 inches of soil.
This short dig gets us across the track and to a field where we can moleplough. We probably have to fill the track back in right away, but we can leave the starter hole for the plough open. If we leave a small hole, then it can be filled later by hand rather than needing the digger back. Because we are filling some of the trench in, we can either lay out a whole field of duct ready for the plough or join the duct.
Turves to one side, soil to the other.
As long as you tuck the duct down below all the broken roots then roots are not a problem. There can be a few spare root ends sticking up after you have finished that need trimming.
A strange ridge of bedrock right across our path. The rest of the trench is okay. We have more experience and a few more items in our armoury these days like slip-on outer ducting, I think we solved that one with a couple of bags of fast-setting concrete.
A during and after pair. One week apart in July. (The bits of orange were markers). We came across some earth wires from the poles in this section.
One of our most challenging sections. A zigzag route through some limestone pavement. Many hours considering alternative routes and then trying to find the best route through this lot with a sounding spike. A few high spots needed the concrete infill solution, you can see the bucket and a bag of postcrete in the picture. Any diggerman will usually enjoy this kind of section but expect swearing.
A digger man will not want to be beaten, especially if you are watching.

In urban areas it is sometimes difficult to get as deep as you would like and where there is a higher probability of someone coming along after you, and digging the same bit of ground up. This is where marker tape is useful. This is a simple plastic warning tape, that is about 9 inches wide and comes on a roll. It has warning writing on it “caution fibre below”. This is laid out in the trench above the duct. It is laid out above the layer of ducting, not with the duct. It should be spread out flat and say about 6 inches above the duct. (It won’t be possible to do a neat job here, but that’s the idea) Marker tape can also be sensibly used in trenches dug by a digger where there is a higher likelihood of the ground being dug up again. Some groups have used electrical marker tape as that often commands more respect from diggers in the years to come.
If you had enough tape and inclination you could use it in all your trenches.
