We have the first 800m installed and have a further 1000m to go. We have now back filled the area over the initial 800m and are now excavating the 2nd part of the field. However, we had to move all of the top soil first that we had piled up on the other half of the field.
This is turning into a lot more work than we first imagined, however, there is no turning back now.
This is the second part of the field that we are going to have to dig up to install the final 1000m of pipework.
Here we have removed the top soil and a strip of subsoil. This takes the soil level down about a 1m – just enough for the ground loops.
More of the field exacavated.
This is the heap of sub soil that we have excavated as the second part of installing the ground loops. There is a lot more to come out before we are ready to install the last 1000m of pipework.
It is difficult to get a sense of the scale, but this heap of top soil is around 8-10m high.
