Continuing on from my last question re digging out my wildlife pond I have returned with a couple of more questions. Work is steadily progressing as you can see.
Firstly, I came across this during my excavations!
After much effort I (with help) was able to get it out in one complete lump! Phew. The hole left, because of where it was, needed filling in. I back filled the area gradually using the clay soil I dug out from elsewhere and ensured I tamped it down really well. Adding a few inches at a time then ramming down. Will this be suffice so as not to cause me bother at a later date?
I appreciate that it is more important to get the level correct around the edge of the pond. It appears, although I have not checked this with level etc that the edge where the lawn is dips and is slightly lower that the edge where the plants are. Should I also build up this edge with clay soil or is there an other way I haven't yet thought off? The lawn edge is where the planned beach/shallow waters will be if that has any bearings on advice.
Thanks in advance. I have found all your advice and comment invaluable thus far.
