All of the ground loops for the ground source heat pump have been covered. The ground loops were pressurised to 1 bar when they were installed. And there are still pressurised to 1 bar after the soil has been put back. At least we know that none of the pipes have damaged while the soil has been reinstated.
We are going to re-lay the topsoil on those areas of the field away from the builder’s cabin and the house. We can then re-seed this part of the field and it will have the opportunity to the grass to grow before the winter sets in. I am guessing that we will reseed at least 1/3 of the field (around 450 sqm) in the next few days (weather permitting).
