I am considering replacing my existing water feature, a drilled slate monolith on a pebble pool
with a wildlife pond, probably around 1 m x 2 m and about 600 cm deep in the middle.
Reading up, it seems that using a butyl liner is more appropriate than preformed pools for this purpose, as the shelving and ramp can be much better tailored. Not sure what the best edging would be.
I still want to re-use the drilled monolith, which is a piece of slate about 600 mm high, and must weigh close to 80 kg, far beyond my lifting capacity. I moved it into place by "walking" it along.
I am unsure how to support it in a stable position in the new pool, and feed the pump hose up the vertically drilled bore.
I have seen suggestions of placing concrete, or presumably a paving slab, beneath the liner and fleece, then building inside the liner upon this solid base.
Since liner installation seems to involve filling it progressively with water, I guess I would then have to empty it again to build anything inside.
I reckon getting the monolith into position would then involve some temporary works akin to pyramid building.
Maybe the pipework would be easier if I managed to cut a slot in the monolith base and introduced a pipe bend of some form. However, that would require the heavy slate to be laid down, and I also need to avoid unwanted splits in the stone.
I welcome any thoughts and advice on all aspects of the project.
Sorry if it sounds like rambling, but it helps me to get my own head round things.
