We have spent most of today back filling the land after installing the ground loops last week. We have installed 1800m of ground loops in the field adjacent to the house. This has been a mammoth task since it has involved removing all of the topsoil and subsoil from this field, installing the pipes and then back filling the field.
Today, the last of the pipes were covered up. Hopefully, we will not be seeing these again for a very long time. The pipework has been pressurised while we have been backfilling. If any of the pipes get damaged, the pressure would drop immediately. Fortunately, the pressure has remained exactly the same throughout.
I took some time lapse video of backfilling the field today. You will find it here on YouTube.
We have made some serious progress today on reducing the size of the spoil heap. All of the subsoil is back down.
This is probably the last we will see of the ground loops. Hopefully. Covered with light grey sand and then buried under the subsoil.
